[PD] [Pd] Multiple audio devices

Wed Jun 11 16:38:01 CEST 2008

I also have problems with an RME fireface (400 model in my case)
I cannot get PD to make use of the asio fireface driver to give me full
duplex...I can only get input or output but not both.
Nick.

hi,
that's cool. did not know that expr can do that! are there more features of
expr that are hidden or unknown??

very nice indeed. i remember sven posted once a way to directly access

hi mika,

have you tried -audioindev 4,7 -inchannels 12? I think you should be 
able to use different soundcards, but maybe there is no possibility to 
use 4 from the one and 8 from the other, but rather all channels from 
both soundcards?? but I don't know about that. maybe -audioindev 
4,5,7,8,9,10?
on the other hand, if the octamic pre-amp is connected to adat1 can you 
do -audioindev 1, and -inchannels 36, does that give you all inchannels?

Hi Hans et al.

I tried the RC1 test build of the latest Pd-extended. Will the Jack  
problem be resolved in this version of do you know?

many thanks for all the hard work everyone!

a friend of mine successfully used exactly the same setup on mac osx.
she also used 12 mic inputs simultaneously in pd, which worked well over
jackosx.

can you elaborate that a bit? i am not too used to windows anymore, but
iirc, using all mme devices sequentially, that are actually driven from
the same card and from the same clock, is supposed to work well.
you might already have tried that: what about accessing just _ALL_
inputs of the card? i don't know, where your octamic is connected to,
adat1 or adat2. if it is on adat2, -audioindev 4 -inchannels 12 wouldn't
work, since this would access actually the analog inputs and some adat1
inputs. try:

-audioindev 1 -inchannels 28

then the [adc~] numbers in pd are not continous, but this wouldn't cause
any harm, would it?

this is certainly not true. pd's execution order is very strict, so it
shouldn't cause any trouble at all to load several samples in 0 logical
time through the same [soundfiler] while keeping track of all sample
lengths. from pd's perspective, everything is processed sequentially,
even if for the user it looks like to happen at the same time. so
conceptually, there isn't actually no 'at the same time', so there is
also no need to wait until all samples are loaded and then ask each
array about its size.

I am trying to reduce a log waveform oscillator (as found with
a charging/discharging capacitor) to it's simplest form.

Note: It uses the soon to be deprecated form of [pow~] (with
reversed inlets)

Attached is the first attempt, and a slight improvement that
saves a couple of subtractions.

Any thoughts on reducing this further?

Also any ideas on constructing a proof that this has the
same spectrum as a triangle wave?

best to all,

Andy
