2 arduinos + VST

Hello all,

I need help to connect 2 arduinos to Max. I can already connect one, using the arduino 2 max patch. Works pretty well, can make some noise with it already, but I still need to connect another arduino. And I also want to play "real" sounds with my software, so I need a way to play VSTs. I have to manipulate the pitch, volume and duration… which software shall I use?

Regards
