What irritates me is this "knocking" sound when the phasor loops back to the beginning, which happens even with your settings, although they set the loop to happen at places where the sample data is almost the same over the 256 samples that lie 128 samples before and after the loop start and end points as the overlaid arrays indicate. I'd assume that the derivatives are sufficiently similar there, and tdditionally he knocking doesn't sound like a click coming from a discontinuity. OTOH the same sound is heard when using for example the [susloop~] external, so maybe it's indeed in the sample data.

[PD] nbx: wrong return-behaviour?
Hi, I always noticed this behaviour, but never rememberd to say something about it. When a number is written in [nbx], it's necessary to press return - just like in a number box. But, unlike in a number box, after typing one value, if I want to type a 2nd value, when I press enter the number goes to 0. The only way to put in a new value is to click in the box again. Isn't this behaviour a bit contradictory? Not just because one number box behaves differently from the other, but also because it makes it much more laborious to input values one after the other. About the normal atom number box, one question: wouldn't it be better to allow it to have patch cords also when it has send/receive variables? (I guess that this has been discussed before).

Re: [PD] naming objects
about the abbreviation, I would think twice. only because there are already lots of objects around, and it might happen that you double some name already used by someone. since there is no system to look at which names are being used and developers don't look much around to prevent it, nameclashes do occur. the good point about the big names (with or without capitals, makes no difference) is that your objects won't be confused with anyone else's. or you use some individual abbreviation technique, like [r_d_s], etc. or you ignore this message. João Pais Greetings Everyone, I am trying to make a gaggle of objects and some of them have spun out with rather long names ([renderDepthSelector] is one example). It seems helpful to keep that name for the object (as it may make the thing more self explanatory), but I would also like to make an option for it to form with an abbreviation (say [rds]) analogous to the way [trigger] and [t] function.

[PD] table abstractions
Hello list, For a while there had been talk about starting a vanilla-only table-abstraction collection in the spirit of list-abs and the iem_tab objects. This could be useful both for manipulation of or calculations using table data and for populating tables with desired data (in the manner of the csound GEN routines). I'd love to start it, but I don't know if I have enough Pd cred yet to be in charge of it. There are a few problems I'd like input on: 1) Naming -- would it be worth it to have different prefixes for objects which manipulated data, e.g. [table-reverse], and objects which populated tables, e.g. [tabwrite-blackman]? 2) Input-Output -- for the ones which manipulate data, should that generally happen in place unless a destination table is provided -- [table-qsort foo] sorts table values in table named foo and writes results back to foo, while [table-qsort foo bar] would sort foo's values and write them into bar? 3) In general I'm assuming that the objects which populate tables should simply write to a table, not internally provide the table to be written to. For instance, I'm thinking a [tabwrite-hann foo] which writes a hann window into foo would be more useful than a [table-hann foo] which internally instantiated a table called foo AND wrote a hann window to it, and responded to messages like "resize" with a larger or smaller hann window (I think accessing the table from without might be too buggy for this to be worth it). 4) Interpolation -- I'm also assuming that anything which would write a table that would usually be read by [tabread4~] or [tabosc4~] should write the guard points for proper interpolation by default. I've attached an example [tabwrite-chebyshev], which writes a weighted sum of chebyshev polynomials of the first kind to a table, probably for use with waveshaping, as an example of what I'm thinking of, and of a few options members of such a collection might have. (Incidentally, it might be a good idea to abbreviate this particular one to "cheb" or "cheby" due to the many transliterations, or even something like "chebsum" to name it like the sinesum or cosinesum array methods.)

Re: [PD] naming objects
Well...that got me thinking. I've often wondered how to avoid nameclashes. If each object has a prefix then this could be avoided. So, jmmmp externs could be called jmmmp.prepend or jmmmp.rds etc (or jmmmp_rds - whatever flavour suits your tongue!) Otherwise there are nameclashes that can seriously screw up a collection of abstractions. So, for example, the latest Metastudio objects have a phasevocoder~ abstraction (using pvoc~ from the bsaylor objects) but a lot of the other objects use the svf~ from cyclone (not bsaylor/svf~). Once bsaylor is imported into Pd-extended, the svf~ will always default to the bsaylor one (that has a denormal error, although I think I fixed this - anyone for testing?) I got round this by setting the objects in PD to cycone/svf~ and bsaylor/pvoc~ (in case anyone else makes a pvoc~ object). But many PD users, especially those used to Mac or Windowze, will not know that you can access the directory structure of the extra folder directly within PD. I think I might have to rename all my abstractions now...or maybe I'm too lazy until it becomes a problem.

Re: [PD] length in midifile
PF wrote: i'm no expert in midi, but i want to send midi notes (and durations) from a .mid file to a synth of mine. i see the midifile help has a bunch of stuff for noteOn and noteOff events, but it's confusing to me. if anyone can clarify a bit i'd really appreciate that. [midifile] outputs lists made up of midi messages, the first item in the list is always a status byte, a number between 128 and 255. So something like: [midifile] | [route 144] | [noteout] will route note-ons on channel 1 to the midi output device, because the status byte for note on is 144. [midifile] | [route 144] | [unpack 0 0] | | will give you the note number and velocity. This works if the file is a single track. For multi-track you might also want to select a track with the [track n( message. Usually the duration of a note is determined when the note-off message is sent. There is a status 128 for note-off but usually note-on with velocity 0 is used instead. If there are controllers in the file you can add a [route 176] and send them to [ctlout].

Re: [PD] Piezo device comanding a bang in Pd through arduino

I was able to download the firmware into arduino, and worked with the popular example of connection to pd found in the web. Now i am interested in knowing what .pde file should I program for the piezo device to be recognized. Finding out how I should connect the piezo to the arduino, and rewireing this to Pd. Not sure what you are trying to do, but could connecting the piezo to the computer's soundcard, and detecting a volume peak within pd, do the same thing?
