Great project here!! Been messing around with pd and I love it...

Currently using pd on my carpc to do basic processing/routing and as a proof of concept/usability testing...so far so good..

Right now this is my audio path/ pd patch...

Winamp-> pd adc in--> master gain--> split to 3 ways with gain control on each line --> pd dac with 8 output --> maudio fw 410 sound card --> zapco dc360.4/dc500.1 amps --> 2 way active front speakers/1 sub

The zapco amps handle the xover, phase, eq and time alignment...

for the next phase of my pd patch I would like to implement the zapco processing.

I've messed around with various vst plugins with audiomulch and had great success...but audiomulch didn't play nicely (no soft/takeover) with my midi controller, plus it cost almost $200!!

Should I integrate vst plugins in my pd patch or can pd handle xovers/phase/polarity eq and time alignment?

Has anyone written patches for this purpose?

Thx for any input ... i go under pcpete on many other forums....you can find more details if u are interested on my setup at mp3car.com

Hmmmm.... I guess I don't understand the question. It seems you are using pd as a 2x8 muxer, which is fine, but jack would probably work better, as it is a daemon and set up for this sort of thing off-the-shelf. The zapco dealie looks to be a DSP engine, so I'm sonfused why you'd want to use pd, or anything software based for that matter, for EQ/xover. You already have special equipment to do that. Perhaps what you mean is that you'd like to control your DSP? In that case: most DSP's I've run accross are serially controlled, or controlled via LAN. If you have the manual, it should have details on the serial protocol and strings.

I want to get rid of the zapco eventually and do all processing via the pc....

i'm using virtual audio cable (vac) as opposed to jack to route audio internally from winamp to pd adc...from there I can process the audio for a 3 way front stage...

so I need lpf , bpf , hpf and delay/phase subpatches...from looking around the docs and samples it seems doable....was wondering if anyone has used pd in a home environment to do this....i've tried some vst plugins (rubber fliter for xover, electriQ for eq, phasebug for phase, voxengo sounddelay for delay) in pd and they seem to work...was hoping to to be able to do it internally in pd....

thx for looking
