[PD] HELP Please! Pd-0.40.3-extended on Windows 7 with Fireface 400 to get 4 outs

[Patrice Colet]

Hello Lorenzo,

 I own a fireface 400 and use it under windows, so maybe I could be some help...

Where do you expect to have 'multiple input/output' ?

if I use FIREFACE asio I can use [dac~ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18]
and [adc~ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18]

just make sure that drivers are not already used by windows system, because it could make
this unstable.

The only command line I use is about setting -asio -audiobuff -audioindev -audiooutdev

when starting pd from a batch file, just to be sure to use asio fireface with low latency and all input/output

but pd would save those settings once it has been applied through pd audio dialog.

 I have sometimes to use pd -listdev to check out where the hell are FIREFACE asio
because audio device number are often moving whenever I have other drivers enabled or not,
but I've heard about some solutions to get/set it from a patch,
maybe IOhannes could give some hints about this.

 Be sure you don't have jackdmp installed because it is conflictual with last portaudio release.

The smallest latency I've been able to use with pd is about twice the buffer size
I could get with any audio interface, something about 2*buffersize/samplerate in seconds

How do you see this?

Do you have fireface working under linux???????
