Bc2000 (for the BCF2000 & BCR2000)

Dear David,
Hi, I'm not sure I correctly understand your question. I'll try to
help but keep in mind I'm not an expert, I made the BCF preset mostly
by copying Kip's great BCR preset, and added a way to "combine" two
commands in one button.

As far as I know, the Shift, Option, Control and Alt functions of the
Mackie controler in Live are "activated" by note-on commands, and
"deactivated" by note-off commands. For example: PlayClip is a Ch1 F7
note-on / off on in "live - mackie language". However, if you first
send an Option command (Ch 1 B4 note-on in live-mackie language), then
send Play Clip (Ch 1 F7 note-on/off) while B4 is still "on", and then
send a B4 note-off, Live interpret this PlayClip command as a StopClip
command. 

And I found a way to send two different Note-on commands at the press
of a button, and two note-off commands when this same button is
released. In fact the preset sends notes with velocity 127 when the
button is pressed, and the same notes with velocity 0 when released. I
really don't know exactly how I did it, just played with the "custom
output" options in BCEditor and found a way that worked.

You could use this technique to group more than two commands in any
button. Just copy the "Opt/Ctrl" button in my preset, and change the
values 71 & 72 (or $47 and $48 in hex, which are the note numbers) to
whatever note you want, and add another "triplet" (144+71+val, or
$90+$47+val in hex) for each additional note you want to "group" in
this button...

Here a great link with the function of eaach note in "live mackie
language":

Hope this helps,
