[PD] best format for send/receive between iOS and libPD

I've got a six voice synth, each with about 20 variable parameters, and then sequence data, etc... and all of this data is being stored by the objective C front-end of my app. can someone tell me, hopefully from experience, what the best format is to send a lot of pattern data between obj C and li

I guess one of the nicest things about what you're showing is to do manipulations ala PWGL or open music. I'm interested in being able to make arbitrarily complex and long scores, and be able to export these as lilypond scores that can be edited and printed for someone else to play… best, J

hi katja, i tried your patch and had a look at it. it’s beautifully programmed :-) so skilled. thanks for taking the time and it’s very interesting to see a different style and different thinking to get to the “same” outcome. i tried (with a different version of the patch) just to replace osc~

Hi Simon, I'd be curious to see this adaptive filtering work in practice. Could you share a patch, once you have that working? Vocals mostly don't exceed a 3 octave range either. Only thing is, in vocals the strongest component is sometimes not the first harmonic but the second, when speaking or s

Well, the follow up to this is that I was able to resolve the problem by installing pure data (Vanilla), pd-cyclone, pd-comport with apt-get. Added /usr/lib/pd/extra/cyclone to the search path (-lib cyclone didn't work for some reason). And it works! I wonder if that means there's something wrong

katja, exactly! i filter the input based on the output of the pitch detection. i used this for quite some time with my doublebass (but with a pickup per string) and it works perfectly. i get no octave jumps or glitches at all. the version i shared here is planned to be used for vocals, i have t

Hi Simon, See attachment for an upsampled version. I used a 6th order lo pass filter with cut off at 1/4 of the original sampling rate. This seems to work with max. 8 times upsampling. Period length error is then limited to 1/8 sample. You mentioned adaptive filtering of a real life input signal.

Hi, more precisely, The number of simultaneous audio streams (called an application in your message) depends on the soundcard hardware mixer and the driver. In the case of the BeagleBone, this probably sums as 1 hardware mixer == 1 application at a time. Cheers, Charles Simon Iten wrote: > Als

Katja thanks for your Inputs! Will Look at the Patch tonight. Simple lowpass Filtering? I tried to upsample with a Block object but the biquad object stopped outputting Pulses. If you don't mind doing a Version with upsampling that would be fantastic. Well i just copied from the Gr300 schematic

Hi Simon, So your method counts samples per (zero-crossing) cycle, is what I learned from studying the patch. Very nice how you do this with tilde objects. It seems possible to get equivalent result with only one [rpole~], when using the positive pulse as trigger for [samphold~] and with two sampl
