Re: [PD] Unity and libpd and multichannel audio (was: Unity and libpd)
by Dan Wilcox 27 May '20

27 May '20

libpd supports the same number of input and output channels as desktop pd. The C# wrapper does as well. If the Unity wrapper does not have an init method to set the number of channels, then they most likely hard coded it to stereo. You may have to look in their code to see. > On May 26, 2020, at 10:11 PM, pd-list-request(a)lists.iem.at wrote: > > Message: 2 > Date: Tue, 26 May 2020 17:11:34 -0300 > From: Fede Camara Halac <camarafede(a)gmail.com <mailto:camarafede@gmail.com>> > To: Pd-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: Re: [PD] Unity and libpd and multichannel audio (was: Unity > and libpd) > Message-ID: <9EE7AC0B-13D1-40B4-B9BE-E9BC3E2C7C0A(a)gmail.com <mailto:9EE7AC0B-13D1-40B4-B9BE-E9BC3E2C7C0A@gmail.com>> > Content-Type: text/plain; charset="utf-8" > > if I need to use more than 2 dacs as output, would these extra channels need to be treated differently on the C# bindings? > > I ask this because, using the repo I mentioned earlier, I cannot get more than 2 channels out and I could not figure out why. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Unity and libpd
by Max 26 May '20

26 May '20

Hi list, it's fascinating just how many individual attempts there are to use libpd inside Unity: https://github.com/libpd/libpd/wiki/Unity Most of the listed projects however have their last changes about 5 years ago and are not up to date with libpd or Unity. And none of the solutions are truly cross platform. Is anyone having more recent experience? m.

Externals work fine with libpd if it is compiled with libdl support. You need to add the path to the external, then use declare to load it. Whoever is providing the C# libpd binary probably didn't compile it with libdl. The compiler flag is listed in the libpd readme. > On May 26, 2020, at 4:22 PM, pd-list-request(a)lists.iem.at wrote: > > Date: Tue, 26 May 2020 11:00:53 -0300 > From: Fede Camara Halac <camarafede(a)gmail.com <mailto:camarafede@gmail.com>> > To: Pd-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: Re: [PD] Unity and libpd > Message-ID: <7B245B40-420A-4CE3-B01D-BBB287BB4C79(a)gmail.com <mailto:7B245B40-420A-4CE3-B01D-BBB287BB4C79@gmail.com>> > Content-Type: text/plain; charset="utf-8" > > One thing I'd like is to have a way of compiling externals to use with libpd. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Add commas to an OSC-message
by Patrick Heidegger 26 May '20

26 May '20

Hello all, I want to send controls for multiple fx-parameters in Reaper with a single OSC-message. Controls for multiple parameters in reaper are defined like: /track/1/fx/2/fxparm/x1,x2,x3,x4/value y1 y2 y3 y4 where xn are the parameter index and yn are the assigned values. I know that commas in PD usually can not be used in this way. Is there any workaround? Thanks in advance, Patrick

udpsend: unsure about raw data
by rolfm＠dds.nl 24 May '20

24 May '20

hi, i want to minimize the data stream send through an UDP connection by sending 'coded' bytes; the receiver(s) will decode them. i'm unsure about the meaning of 'raw data' in the helpfile of [udpsend]. does [1 2 3( represent bytes with the octal vaue 001 002 003, or the integers 1 2 3 which will be 'translated' into the octal bytes 061 062 063 ? it's a bit ambigious for me, especially comparing the helpfiles of [iemnet/udpsend] and [mrpeach/udpsend]. with the iemnet version one cannot send files directly, it's necessary to use [binfile]. does it mean that the mrpeach version recognizes that a file is used for input; wow that [binfile] is embedded in its [udpsend]? rolf

Re: [PD] MIDI in channel looks wrong
by Philip Stone 22 May '20

22 May '20

Hi Christof, You are absolutely correct; I was on port 2. I guess I've never used port 2 for any MIDI devices before, so I never knew that the channel values for the midi-in objects behaved that way. It's not explained in the help patches, either. At any rate, all is working well, now that I know how to use the channel value. Thank you!

MIDI in channel looks wrong
by Philip Stone 21 May '20

21 May '20

Hello, I’ve connected a Behringer X-Touch Mini to PD (0.50-2) on OS X Catalina, and the raw data coming into [midiin] looks fine, but the [ctlin] and [notein] objects are reporting a channel of 27 (it should be 2). Since that’s not even a legal channel number, I’m wondering if this is a bug. Best, Phil Stone Davis, California
