[CM] ring-modulate
Hi, I'm getting confused over ring-modulate ex. in manual vs. ring-modulate code in new-effects.scm. Manual: ring-modulate in1 in2; returns (* in1 in2) And new-effects.scm seems to show map-channel using frequency and radians: (rm-effect rm-frequency #f)) ;(list 0 0 1 (hz->radians rm-radians)) I'm trying to use a reader and apply ring-modulate to the snd. (with-sound (:play #t) (let ((reader (make-readin "mywave.wav"))) (do ((i 0 (+ i 1))) ((= i 602866)) (let* ((mysnd (readin reader))) (outa i (* 0.5 (ring-modulate xxx xxx)) ;not sure what it wants here? But whatever I use as input to ring-modulate I'm not getting close to the new-effects.scm application of Ring modulation which uses frequency and radians. Wondering where I'm getting confused.

[CM] select color
Hi, re: select-color Geez. Wayland was the problem. That was bothering me for a couple weeks. Somehow the f39 login setting for Gnome became set to Wayland instead of Xorg.

[CM] edit selection color
Hi, This is a bit odd, but I'm posting in case someone might have a suggestion. I'm on fc39, Snd 23.9, using motif, no gl. I've recompiled Snd a few times recently trying to solve a wacked color problem with the edit selection color. When I select an area to edit, the color is yellow with a red tinge looking something like overlay or spectrum instead of the default lightsteelblue1. I've defined using make-color and set selection-color to change the color from the listener a few times but the edit color just gets worse. I tweaked colors in preferences, and checked nothing is odd in my ./snd prefs file. In the preferences color panel other colors seem okay. Seems to only affect the selection-color. I upgraded my ram from 8gb to 16gb recently and I'm thinking maybe the wacked edit colors have something to do with rgb and ram? I also changed the laptop's color profile a few times using Genome's Settings for Colors, but no joy there either. Stranger still if i select and area for editing, leave it selected, and open any other menu (ex. reverbs), and close that menu, part of the reverbs menu is showing up faintly in the edit area of the waveform. That's very odd but gets me thinking about screen refresh and memory issues. Maybe the ram was bad, but strange it only seems to affect the edit area for color.

[CM] make-sampler vs. open
Hi, Yes. Snd's make-square-wave works great. I took another look at my code and figured out the problem was not reading from make-sampler, but my trying to get the maxval of the sampler's output to see what was going wrong. I was using (set! maxval (float-vector-max (float-vector-abs! im))) and didn't realize float-vector-abs! was setting all the values to absolute value. I thought it was just getting the abs value. So for a square wave that's deadly. My fault.

[CM] make-bandpass
Yes. Understood. That's very helpful information. I see I can use mus-xcoeffs with make-bandpass. I think I wasn't indexing it properly too. If I might continue to ask, what are the numbers ouput from the generator, ex. (bandpass b)? I know the xcoeffs are the filter magnitudes but when nothing is passing thru the filter yet, as it would be if one were to call (outa i (b (* amp (oscil os, what do the output numbers of the generator represent before the filter is applied to a source? Are they random sample amplitudes, for ex.? (let* ((b (make-bandpass (hz->radians 500.0) (hz->radians 2000.0) 3)) (v (make-float-vector 3)) ) (do ((l 0 (+ l 1))) ((= l 3)) ;(float-vector-set! v l (bandpass b l)) ;what is output here? (float-vector-set! v l ((mus-xcoeffs b) l)) ;filter magnitudes (format #t "~%l: ~F v: ~0,6F" l (v l)) ) (do ((l 0 (+ l 1))) ((= l 3)) (format #t "~%j: ~F v: ~0,6F" l (v l)) ) ) ...also (sorry this long-winded) when I see a lambda func adding the two bandpass filters, ex. (flt3 (lambda (y) (+ (bandpass flt1 y) (bandpass flt2 y I cannot get the mus-xcoeffs of flt3 then, because it's now a lambda function. So my purpose was to prove to myself that the lambda func was indeed the same as adding two vectors of mus-xcoeffs. (float-vector-add! v1 v2). In other words trying to see the numbers to verify the lambda function is indeed adding the xcoeffs, not the generator outputs. I hope that makes sense. But I'm still failing in my proof.

[CM] make-bandpass xcoeffs
Hi, It seems make-bandpass doesn't have the mus-xcoeffs feature as general make-filter does, but I was trying to get the numbers to do some comparisons all in one definstrument, define, or let. It seems calling the make-bandpass function as a generator and trying to place the output into a vector is the wrong approach, or maybe I have the inp variable wrong? Also it seems one can use a bandpass or fir-filter call interchangeably? How can I best get accurate xcoeffs numbers in-line, so to speak, from the make-bandpass gen?

[CM] out
Hi, I think I've had a basic misunderstanding re: re stereo and using out such as outa, outb, outc, outd. It seems to sum rather than provide discrete outs? I'm just checking I'm not going bonkers looking at the fft of the output signal. I know locsig works differently ex.1 results in 880 hz on a and b, but would expect 440 on a and 440 on b. (with-sound (:play #f :channels 2) (let ((gen (make-oscil 440.0))) (do ((i 0 (+ i 1))) ((= i 48000)) (outa i (* 0.5 (oscil gen))) (outb i (* 0.5 (oscil gen))) ))) ex.2 but to have have the same signal on both channels I need to use 2 gens? (with-sound (:play #f :channels 2) (let ((gen (make-oscil 440.0)) (gen2 (make-oscil 440.0))) (do ((i 0 (+ i 1))) ((= i 48000)) (outa i (* 0.5 (oscil gen))) (outb i (* 0.5 (oscil gen2))) ))) Or how do you best do stereo using out?

[CM] portamento
Hi, I'm still pondering how best to accomplish this. I tried a couple of exs below, one adding filters. I thought bandpass was best to try but couldn't get good high cutoff results with just one filter so I went to two overlapping bandpass filters. But I've buggered the freqs by an octave somehow. That could have been in using hz->radians as cutoffs. I think my experiments still sound too glissy overall. I'm wondering if there are other suggestions? Thank you, Jim ;no portamento.

[CM] mus-chebyshev-u-sum
Hi, I'm trying and failing to get my head around mus-chebyshev sums. For predictability I was trying to achieve the square wave output but getting hung up. The manual says mus-chebyshev-tu-sum and friends perform the same function as partials->polynomial, but it takes a coeffs vector too, so I'm confused about how you would perform additive synthesis (as square wave) with it? I get the parts about phase, and ability to set individual partial amps etc., but can't quite figure what coeffs needs. My three tries for the coeffs vector don't seem to work. I guess I'm thinking phase and amps are not all that critical as long as the coeffs are correct, but I could be wrong. But maybe it's the other way round where you can only do it thru phase and amps and the coeffs are not that critical.

[CM] loading libc_s7.so

Hi Bill, Yes, that's very helpful.

(xxx (make region beg end snd chn)) I tried the string-append approach, but doesn't seem be the best method since (type-of) shows the variable (xxx) as a c-object.

Re: CM, Grace, JUCE Fedora31 I rechecked my JUCE dependencies, thanks Frank Sergi, but all was ok. I spent several days dialing around with different versions of juce and cm. Still no joy. I think the current problem on Fedora is with gcc/g++ 9. It complains about the PixelRGB problem. Guess I'll wait a bit for things to catch up with the compilers.

Hi, re: Circular-Scanned bracket error. It was my fault. Sorry. It's been a while since I've been in CLM-5, since mostly using scheme w/emacs. I forgot from emacs the M - x, slime-compile-and-load-file command is only useful for .lisp file, not .ins file. Although I can Ctrl -x Ctrl - f, load the .ins, it gives an unmatched bracket error (below) at the beginning of definstrument if trying to run M - x, slime-compile-and-load-file. I needed to rename the .ins to .lisp, then it goes thru fine. ...BTW, I have a small side project to try to convert that very cool .ins to scheme using the dotimes, and setf! macros from Bill's scheme, but still getting hung up in the run loop which is quite tricky. Be good sometime if it could make it over to a .scm file. Be glad to share what I have so far.

In the env-channel case, the vector is treated as an envelope and applied to .015 seconds of samples, but in the float-vector->channel case, the vector itself is simply copied into the file. It only has 8 samples, so in the float-vector->channel case, the blips are 8 samples wide, rather than .015 * 48000 = 720 samples.

Float-vector->channel works fine if I employ the vector as envelope across the whole snd., but I'm failing to understand how to employ it for successive back-to-back edits within the snd. Thank you for Snd 18.7! Regards, Jim (set! (mus-srate) 48000) (let* ((mysize 8) ;size of vector for envelope pairs (fsize 48000) ;size of the snd (myvec (make-float-vector mysize)) ) (new-sound "test.snd" :size fsize) (insert-silence 0 fsize) (map-channel (lambda (y) 0.5)) (float-vector-set! myvec 0 0.1);x1 (float-vector-set! myvec 1 0.5 );y1 (float-vector-set! myvec 2 0.5 );x2 (float-vector-set! myvec 3 1.0 );y2 (float-vector-set! myvec 4 0.75 );x3 (float-vector-set! myvec 5 -1.0 );y3 (float-vector-set! myvec 6 1.0 );x4 (float-vector-set! myvec 7 0.0 );y4 (do ((i 0 (+ i 1000))) ((= i 24000)) (env-channel (make-env myvec :duration 0.015 :scaler 1.0) i 1000 0 0 ) ;(float-vector->channel myvec i 1000 0) ;place float-vector in the editor ;XXX )) ___ Cmdist mailing list Cmdist@ccrma.stanford.edu https://cm-mail.stanford.edu/mailman/listinfo/cmdist

Hi, Thank you. I think I get it now. I was thinking "i" was smarter about values while going thru the do loop, or was was keeping track somehow of all values, not just the increment. But it seems to only know about values of the increment. I think I can fix it now.

[CM] map-channel with dsp
Hi, I'm really stuck on trying to use map-channel to replace a newly created snd file with a dsp modified version of it. I've been looking at snd-test.scm for examples but still don't have it right yet and not sure how to craft the let/map-channel/lambda to make it work. All I get is a flat line so far. I'm trying to place values in a float-vector, then modify those values and output to the editor. I know (float-vector->channel im 0 fsize 0) works, and I also tried sample (but very slow): (do ((i 0 (+ i 1))) ((= i fsize)) (set! (sample i) (im i))) Wondering if there's an example someplace I haven't found yet for how to dsp modify a vector of values and use map-channel to output to the editor? Thank You, Jim I’ve been trying something like below… but cannot seem to get the map-channel/let/lambda part right. (let* ((fsize 22050) (increment (/ (* 440.0 2.0 pi) fsize)) (im (make-float-vector fsize)) ;empy vector (current-phase 0.0) (val 0.0) );init var (new-sound "test.snd" :size fsize) ;creates a new snd in editor ;place values in a vector (do ((i 0 (+ i 1))) ((= i fsize)) (set! val (* .1 (sin current-phase))) (set! current-phase (+ current-phase increment)) (set!

[CM] generators
Hi, I've been using the generators in generators.scm for a while, and enjoy making sound with them, but for the life of me I cannot seem to understand how they work. I'm confused about the lambda part and the use of fm. What is fm doing? I'd be grateful if someone could explain that. Such as in nxycos, It seems like (set! angle (+ angle fm frequency)) is critical, but is (+ angle fm frequency), simply the sum of those variables, such as (+ 3 1 2), > 6? Or does the fm part contribute to the radians value of angle in some other way in that bit of code. I've tried using display and formatted output to look at output values such as x, y, den, angle in radians in lambda, but nothing is really making sense to me yet. I've also experimented with input of different values and viewing the fft outputs to see the frequency in hz, ratio, n, and also angle or phase start in the waveform view of snd. For ex. if I do something like: ... (outa i (* .5 (nxycos gen 0.1)) such as adding a value for fm, then the frequency really takes off, so I'm not sure I'm understanding what fm does in the generator or how it's supposed to be used. Thank you, Jim (defgenerator (nxycos :make-wrapper convert-frequency) (frequency 0.0) (ratio 1.0) (n 1) (angle 0.0) fm) (define nxycos (let ((+documentation+ "(make-nxycos frequency (ratio 1.0) (n 1)) creates an nxycos generator.

[CM] make-pvocoder
Hi, I'm working thru snd make-pvocoder, clm make-phase-vocoder trying to find more info on the analyze, edit, and synthesize methods, such as the one below the manual which shows a lambda func for the synthesis or resynthesis method. Most of what I've been able to find is based on a gen from readin of a file or input samples to access spectral data. I know this is a bit odd, but I was trying to create designer spectra, by filling empty vectors with various numbers etc, as opposed to getting the data from a readin generator. So far mine just sounds like noise, so I don't have it quite right. I'm wondering if I'm on the right track by using original vectors in the analyze, edit, and synthesize methods. Or maybe I should just be creating sound files using something like infinite sums, for example, and sticking with the readin generator to analyze those sounds? I've looked at at the moving-spectrum and pins insts too.

[CM] s7 wrap c func with scheme
Hi, I had a question about wrapping a c func with scheme, s7. I'm trying to understand how to wrap the declared function from the .h file with scheme in a .scm file (mywrapper.scm) so that it can be called from s7 and use the shared library. > (load mywrapper.scm) > (myfunction) > (exit) I have a .c file which includes a function (myfunction), and .h which declares that function. I compile the .c file using -fpic into an obj. file, then create a shared library, ex. mylib.so. I'm looking at SND files libc.scm and libgsl.scm which seem to be wrappers, but are quite complicated. I'm also looking at the S7 manual example for "Load a shared library", but there are static s7_pointer functions in the example's c code which seem to be doing the wrapping on the c side as opposed to wrapping a c function in scheme using a .scm file. I'm wondering if there's a simpler example somplace where I can get some ideas about how to go about wrapping a c function in scheme, or if the manual vers. is the preferred way to go, i.e. create a library using s7 functions from c, and then load the library into s7 to call the function?

[CM] scheme, larger structures
Hi, I had written about a scheme method to do something similar to CLM's with-mix for larger compositional structures using multiple instruments and Bill had replied... "If you want to concatenate several with-sounds into one, just concatenate the instrument calls, with some variable holding the section's start time." I tried several ways to concatenate definstrument calls and place those with the body of with-sound, but nothing seems to work. It seems like ws.scm just wants a direct call to a definstrument in the body part. I gave up and tried concatenating with-sound blocks instead, and it works after a fashion but the creation of separate audio files means those still have to be stitched together at some point. At least this is getting closer to what I was after. regards, Jim (load "/opt/snd-16/CM_patterns.scm") (define (round-off z n) (let ((power (expt 10 n))) (/ (round (* power z)) power))) (definstrument (examp1 start-time duration frequency amplitude) (let* ((beg (seconds->samples start-time)) (end (+ beg (seconds->samples duration))) (sine-wave (make-oscil :frequency frequency))) (do ((i beg (+ i 1))) ((= i end)) (let ((x (* amplitude (oscil sine-wave (outa i x) (outb i x) (definstrument (examp2 start-time duration frequency amplitude) (let* ((beg (seconds->samples start-time)) (end (+ beg (seconds->samples duration))) (gen (make-polywave :frequency frequency :partials '(1 1.69 3 5 (do ((i beg (+ i 1))) ((= i end)) (let ((x (* amplitude (polywave gen (outa i x) (outb i x) (let ((var '()) (aaa (make-heap '(360 800.345 1200 600))) ;freq (bbb (make-cycle '(1 1 .75 .25 .20 .15 .10 .10 .10 .10))) ;dur (ccc (make-heap '(241 840.345 1000 960 500))) ;freq (ddd (make-cycle '(.2 1.25 .75 .25 .20 .15 .10 .10 .50 .10 .50))) ;dur ) (set! var (cons (with-sound (:reverb nrev :output "Test1.wav" :srate 48000 :channels 2 :header-type mus-riff :statistics #t :play #t) (let ((i 0)) (do ((k 0 (+ k 1))) ((>= k 25)) (let ((v (next bbb))) (examp1 i v (next aaa) .3) (set! i (+ (round-off i 2) v)) ;;end of with-sound (with-sound (:output "Test2.wav" :srate 48000 :channels 2 :header-type mus-riff :statistics #t :play #t) (let ((j 1)) (do ((k 0 (+ k 1))) ((>= k 25)) (let ((v (next ddd))) (examp2 j v (next ccc) .1) (set! j (+ (round-off j 2) v)) ;;end of with-sound ) ;end var ) ;end set! var ) ;end let ___ Cmdist mailing list Cmdist@ccrma.stanford.edu https://cm-mail.stanford.edu/mailman/listinfo/cmdist

"If you want to concatenate several with-sounds into one, just concatenate the instrument calls, with some variable holding the section's start time."

[CM] Snd inf-snd.el
Hi, I finally got Snd working as an emacs subjob with help from Micahel Scholz. Some of it had to do with the way the .emacs file was being called, which meant the load-path variable was not being completed properly. It's neat to be able to load a .scm script, edit it, and hear and see the results in the Snd motif gui by controlling the code from emacs. I've tried reading all the Snd documentation to figure out how you might load a .scm file in the lisp listener, edit it in the lisp listener, and evaluate it in the lisp listener, but I haven't yet found how you would do something like the inf-snd.el snd-scheme-mode to bind the usual key commands for use within the Snd lisp listener without writing your own listener. I must be missing something important, someplace. Regards, Jim ___ Cmdist mailing list Cmdist@ccrma.stanford.edu https://cm-mail.stanford.edu/mailman/listinfo/cmdist

Snd can communicate with emacs through s7, forth, or ruby, and inf-snd.el has instructions. I use the built-in repls (and a separate emacs); in that case you load a file with (load "a-file.scm"), and evaluate s7 code by typing it at the prompt, just as in any other repl. Hi, Thank you. This is a bit clearer now. Since I don't need slime, quicklisp or sbcl, then maybe just a separate .emacs file is best approach than trying to combine everything into one .emacs startup file? Or maybe I'm getting confused about .emacs vs. .el files somehow? I've read inf-snd.el , but not sure I understand it all yet. For my .emacs, and just the scheme part, I tried below using the snd customization and extension example from Bill's ~/.xemacs/init.el shown in the snd html manual for the inf-snd.el part, and then tried loading a .scm file from emacs but nothing is happening so I don't think I'm there yet.

Hi, I'm finding myself s7 challenged, trying to do an example using CM_patterns.scm in Snd using the listener. Seems that Snd doesn't have process, sprout etc. which Grace allows for working with patterns, so trying to figure out how to set up a control loop in with-sound in Snd using the patterns, but getting a bit confused.

[CM] Scheme, Outa, and reverb
Hi, I'm getting myself confused about the following info below from the manual about outa and *reverb*. If I'm understanding correctly then, *reverb* is not a reverberator and you still have to supply one, such as jc-rev, which I think I did below using with-sound. But I'm stuck trying to figure out how to use a reverberator with a scheme process instead of with-sound. I know I can include the the reverb-amount etc. on the send line in the process, but I can't seem to figure out how to to include the jc-reverberator with the process or define. Do I include the reverberator in the definstrument perhaps for calling it with a process? I know using reverb from a scheme process is much easier if I use locsig instead of outa, but I was hoping I might understand if will work or not. Thank You, Jim -- *reverb* The reverb instrument has to send to the *reverb* output stream an appropriately scaled version of its main output, something like: (outa i (* sample reverb-amount) *reverb*) What clm does is, after with-sound processes the whole note list that is its body, it runs the reverb instrument that you supply over the reverb soundfile that it generated as part of running the body and then merges the output of that instrument run into the main soundfile generated.

Hi, Using Snd and getting unbound variable error on analog-filter.scm for line 309 gsl-roots. I configured Snd --with-gsl, and have gsl and gsl-devel on my machine. I also compiled a simple exampl.c in gsl using bessel functions and it compiles and runs o.k. I'm wondering what might be going wrong or why it's not able to get to gsl? Thank-you.

[CM] defvar global list
Hi, Working in CLM with a .clm file, getting confused with lisp, and I was hoping I could get some help from lisp experts here. I'm confused why collecting into a global list is not available from the second loop, in ex. 1. I'm wondering if I'm not understanding something about scope. Should the loops from ex. 1 be wrapped with something else like a let statement? I can access the global list by defining a function in ex. 2, but curious where I'm going wrong in ex. 1? ex. 1 (defvar mylist '(0.5 100.0 200.25 4000.0 1.0 0.33)) (defvar *test* '(nil)) (loop for i from 0 to 10 by 1 for xx in mylist collect (random-element mylist) into *test* finally (return *test*)) ) (loop for i from 0 to 10 by 1 for yy in *test* ;the randomized list above does not seem available as global here do (format t ~A yy) ) -- ex. 2 (defvar mylist '(0.5 100.0 200.25 4000.0 1.0 0.33)) (defvar *test* '(nil)) (defun myfunc (somelist) (loop for i from 0 to 10 by 1 for xx in somelist collect (random-element somelist) into *test* finally (return *test*)) ) (loop for i from 0 to 10 by 1 for yy in (myfunc mylist) do (format t ~A yy) ) ___ Cmdist mailing list Cmdist@ccrma.stanford.edu http://ccrma-mail.stanford.edu/mailman/listinfo/cmdist

[CM] green, butter clm
Hi, For CL/CLM manual under other generators, I'm trying to understand the implications of green.cl and butterworth.cl. green.cl defines several special purpose noise generators. butterworth.cl has several Butterworth filters. (See analog-filter.scm in the Snd package for functions to design all the usual analog filters; the output is compatible with CLM's filter generator). I think I've understood green.cl, but stuck on butterworth.cl, however I did get the Snd analog-filter.scm working in Grace and Snd. For emacs/slime/lisp with butterworth.cl was trying below, but getting memory errors. Not sure if I understood what .cl is for? I just named it .lisp, added the instrument below to it and tried to compile and load that. I'm thinking I'm off on the wrong track about how the butterworths are intended to be utilized in clm. (definstrument mybutter (beg dur freq amp) (let* ((start (floor (* beg *srate*))) (end (+ start (floor (* dur *srate* (flt (make-butterbp 200 .5)) (os (make-oscil freq))) (run (loop for i from start to end do (outa i (* amp (filter flt (oscil os (with-sound (:channels 2 :srate 48000 :header-type mus-riff :output testbutter.wav) (mybutter 0 5 400 .7) ) ___ Cmdist mailing list Cmdist@ccrma.stanford.edu http://ccrma-mail.stanford.edu/mailman/listinfo/cmdist
[CM] slime printing
re: clm emacs-slime ...might be a bit OT I was hoping to get some advice on printing from emacs-slime. I'm trying to print output to a visible area of the emacs editor when the code is compiled and runs, such as in with-sound below. I'm using f20, sbcl, emacs-slime, and clm but having a devil of a time getting any contrib to load and run with my .emacs file which might support more repl such as to the echo area etc. I'm wondering what approach you folks might use to print to std out? Are you using a contrib package or other editor and print .el utility files? I've tried things like (print ), and (format t ...) and (message ...), and those evaluate the expression to the echo area but they don't work when I compile and run and it is beeping. Or am I totally off base, and lisp doesn't do that very well at all? Thank You, Jim (definstrument simp (start-time duration frequency amplitude optional (amp-env '(0 0 .5 1.0 1.0 0))) (multiple-value-bind (beg end) (times-samples start-time duration) (let ((osc (make-oscil :frequency frequency)) (amp-env (make-env amp-env :scaler amplitude :duration duration))) (run (loop for i from beg below end do (outa i (* (env amp-env) (oscil osc) )) (outb i (* (env amp-env) (oscil osc) )) ) (with-sound (:channels 2) (loop for tt from 1 to 10 by 2 do ** (print tt) *** (simp tt .25 220 .75) )) ___ Cmdist mailing list Cmdist@ccrma.stanford.edu http://ccrma-mail.stanford.edu/mailman/listinfo/cmdist
[CM] cm 3.9 kde desktop
Hi, I got a fedora build of cm 3.9, but am having a KDE issue since the fedora20 upgrade. Error: load file /home/fedora2/Object::connect: No such signal org::freedesktop::UPower::DeviceAdded(QDBusObjectPath) Object::connect: No such signal org::freedesktop::UPower::DeviceRemoved(QDBusObjectPath) does not exist. The error shows thru the Grace console, and is a KDE problem but renders the file editing in Grace such as .scm and .sal files useless. Doesn't show some text and won't allow you to enter text. Nasty problem. CM 3.9 is working fine on Mac and on my f20 with gnome desktop however, so just thought I'd post this here and see on the off chance if there might be another KDE user who's figured out the UPower, or ibus, or dbus problem. I just just went thru a bunch of KDE upgrades and was hoping that would do it but no joy.

Also followed gnome instructions for adding icon to app on fedora with gnome:
Place the icon in

Then after build is complete right click grace app in bin directory, select
properties, then click on the icon image on properties page and associate it
with cm.png.

[CM] clm, evelope with reverb
Hi, I'm getting better at using reverb but wrestling with trying to include amplitude envelopes in the instrument now. The reverb (locsig) is working for me, if I just use amplitude instead of the amplitude envelope on the output stream, but if I try to employ the amplitude envelope I loose the reverb. (locsig loc i (* amplitude (oscil osc) )) ;works fine (locsig loc i (* (env amp-env) (oscil osc) )) ; no reverb? I've tried several changes to the ins but not sure I understand why (env amp-env) takes away the reverb?

[CM] clm, slime, reverb
Hi,
For explanation or reverb. Thank you for that info. I'm still trying to
understand what it means by example. I don't think I quite have it yet. My
try below just seems to be increasing gain but not creating reverb. I also
looked at locsig explanation in the clm manual, but that's a bit beyond me to
start. I just need a simple understanding of how reverb is working in ins
design to help get started. Are there any simple examples around? I've
grepped thru clm-4 and snd but don't see much by way of example for nrev,
jcrev, or rev2.
I'm getting hung up on the out-any part with trying to add reverb to the
stream. For ins with complex outputs a clearer example of wet/dry would be
appreciated to see how it's done.
re: The reverb instrument has to send to the *reverb* output stream an
appropriately scaled version of its main output, something like:
(outa i (* sample reverb-amount) *reverb*)
What clm does is, after with-sound processes the whole note list that
is its body, it runs the reverb instrument that you supply over the
reverb soundfile that it generated as part of running the body and then
merges the output of that instrument run into the main soundfile generated.
