"How do you send a continuous controller message with a button push?"

From John Fera at Peavey:
-------------------
Sure you can send CC's by programming a string: 

Bx cc dd, where 
x is channel-1 (0-F)
cc is controller # (00-7F)
dd is data value (also 00-7F)

You can program the Bx as B0-gc. This will let the global ChOut
variable (utility screens) channelize the controller instead of
hardcoding it in the string.

The list of controllers is on page 25 of the MIDI spec. It can be
purchased from the MMA, but there are plenty of people who post
similar lists on the web, so you may want to search around a little and
find it for free.

I have a single-page MIDI summary on my wall that has proved
invaluble over the years. I've got it on my website - print it out and
hang it if you're learning MIDI:

Good luck,
John
