Re: Controlling Valves/Relays from PC

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

I was concerned about the number of channels, as well, but that shows 
I'm stuck back with my Roland JX-8P and 6-voice polyphony - and it can 
respond on only one channel.

Now I did wonder about assigning a different "pitch" to each valve. A 
good sequencer can send "pitch" signals out on several channels, as I 
recall. That would maybe take care of the number or valves he is 
controlling.

And the main reason I brought up MIDI at all is, it is really and ON/OFF 
kind of thing. And he could coordinate everything, including music and 
video with such an app.

I've asked a friend who has been in the electronic music biz awhile, 
including some work on Garritan (?) sounds used in Finale.

I'm just glad I finally learned to use the patch chain feature of my JX-8P!!
