Hi,

Chasing some advice on sequencing my Access Virus C with my 
MachineDrum by using the "Midi" machines...

Basically, how do I use program change messages with the MD and the 
Virus?

I set up a midi machine to paly the Virus on say, channel 1. The 
default program change is say; 8

If I then try and change it on a step then it sends a control change 
message for that 1 step only.  (and stuffs up the sound by making the 
virus flick patches for one step)

Do I need to setup different kits with different midi machines?

Or anyone else got any advice on doing this? Especially with the 
Virus?

Thanks,
Rusty
