[PD] Looking for solutions to the indexing into large arrays problem

I'm finally getting around to trying to modify my looper patch to be able to index into long arrays, using the solution suggested. I am sorry to say the onset for [tabread4~] does not seem sufficient IMO (if my understanding is correct). The single precision index provided by the left inlet of [tabread4~], which seems safe in the range (0..150,000), which is typically driven by a phasor~, is *added* to the right inlet. So instead of first hearing distortion at 150,000 samples --- 3.4 seconds at 44.1Khz) -- this is the example in B15 Using Onsets into Tabread4~ to provide accuracy-- Now, we have deferred the problem to 300,000 samples, *6.8 seconds!* Do I have this right?

I am intermediate PD programmer, about 9 months into patching. I really love PD, despite some quirks. The single most annoying issue I have found so far is the inability for PD to accurately index into large arrays. The way this manifests is very curious! I first noticed high frequency noise at maybe 6 min. into an array, which gets worse as you move into the file. At 20 min, it's really horrible. I would say the root cause is a) lack of a long integer datatype. Friends, sometimes you really want ints, like accurately indexing into an array, and b) lack of precision in (short) floats. People on the FB group promptly told me this is a well-known issue, and directed me to PD-double. This sounds like a wonderful project, however it seems it is only beta, and breaks several of the modules in extended. So I am wondering 2 things: 1) What solutions have people come up with for accurately reading big arrays at audio rate, using either pd-extended or vanilla? (I have considered breaking the big file up into smaller arrays, but this is cumbersome). 2) What is the long-term goal at solving this problem?

Note that I was only on a laptop so I don't know how relevant this is to your question. Below is the solution I found on the Max forum (I don't have the link right now but it should come up on google). 1- Read the file [silently] from disk (using sfplay~ or equivalent), at 50 times the original speed and record the output into a buffer that is 50 times smaller than the original file. 2- You can navigate through this smaller buffer and multiply the output by 50 to get the correct time pointer into the original file. I then read the original file from the disk, instead of loading it into a buffer. 3- Since I'm making my patch for concert playback, I have put in place a checking mechanism that looks for an existing 'waveform' file. (The patch automatically names these originalFileName.wave.aif.) If it exists, the waveform file is read into the buffer, otherwise, the loaded soundfile is 'analysed'. I can send you my patch if you are interested. I don't see any reason why this can't be implemented in PD. Although the graphical scrolling might be slower in PD. I'd be interested to know if this works in PD.

As there is no way to get Max patches run on mobile devices, I want to do it in PD using the MobMuPlat apps for Android/iOS. The task would be to simply to play a stereo sound file, but of about one hour lebgth. As MobMuPlat only supports vanilla PD I am restricted to that as far as I know. In the docs and on the net I did not find any way to navigate within that playback. (Its crucial for rehearsals.)

Re: [PD] pd in a eurorack modular system
Hi i have made some advances. I installed Debian Wheezy onto the Raspi I programmed the arduino to excpet the potentiometers and all 6 react from 0-1023 They are both responding I found the same bug where pd -nogui needs about 1/2 second to boot before turning on the dsp I also had to change the WProgram.h to Arduino.h in the Simple Messages System library which works well when placed in Arduino/Libraries. Now i am looking for a nice pd patch that can granulate sound without the need for a table to be written first. I am looking at Bill Orcutt's Grain2.0 port.? in conjunction with the Arduino2pd patch. more soon. if anyone has any suggestions for a fun effects patch please link or attach one! pp Patrick Pagano B.S, M.F.A Audio and Projection Design Faculty Digital Worlds Institute University of Florida, USA (352)294-2020 From: Pd-list pd-list-boun...@mail.iem.at on behalf of tim vets timv...@gmail.com Sent: Friday, April 17, 2015 6:06 PM To: Tilo Kremer Cc: pd-l...@iem.at Subject: Re: [PD] pd in a eurorack modular system 2015-04-15 0:57 GMT+02:00 Tilo Kremer p...@dadacafe.orgmailto:p...@dadacafe.org: Hello, On Mon, Apr 13, 2015 at 8:01 PM, Peter P. peterpar...@fastmail.commailto:peterpar...@fastmail.com wrote: * Pagano, Patrick p...@digitalworlds.ufl.edumailto:p...@digitalworlds.ufl.edu [2015-04-13 19:53]: Hi I am building my first modualr system with a little grant money i got for research.

Mounting holes and solder holes are also provided to connect and mount the midi part after separation. For Eurorack connectivity, voltage levels for control voltage in- and output must still be shifted from 0..3.3V to 10V externally and thus will require some DIY work. from https://www.indiegogo.com/projects/axoloti-a-digital-audio-platform-for-makers#comments gr, Tim hth, tee ___ Pd-list@lists.iem.atmailto:Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] GUI lock ups
Hi all-- I use 0.43.4-extended on Windows 7. Whenever I have one or more [metro]'s running 30ms, I commonly get GUI lockups. Bangs still blink, but sliders and number atoms and other elements are frozen. They still work, they change value, but the GUI does not update. The problem seems to become more likely as the interval reduces. I can get 20 mins sometimes at 30ms, but if I bring it down to 10ms, it locks up in just a couple of minutes. Has this been fixed? Is this a reason for me to move to main-branch Vanilla?
