Hi nickrose thanks for your answer

Yes i have the PA-422!

if i can use midi is great,i have more experience with midi devices,i must ask because my pc is not in a ready use!!  " Vsig" can communicate with the DSP4000 via midi?

From your answer i understand it is,i will read the manual for more info.

One more thing about the "vSigX" (mac) can it also be used with midi?

in the "vSigX" preferences i see the midi option but it appear that i can't enable it! any info about that will be great,i will also read the manual for more info!

i must ask for these guide lines it help me to get in to proportion.

Again big thanks….
