Bc2000 (for the BCF2000 & BCR2000)

Hello all

I've customised a BCF2000 b-control mode preset emulating Mackie 
control mode which I found in the group which I use with Ableton Live 
in Mackie mode.  I'm trying to understand how multiple button 
presses, i.e. shift+button, are supported by the Live 
implementation.  

Sniffing the BCF in Mackie mode I can see firmware handles shift key 
modifications of target midi note values, but in b-control mode I 
also see note on sequences that perform different functions on the 
target button, e.g. using the EXIT button to modify the function of 
teh STORE button defined in the preset as starting (STORE) or 
stopping (EXIT+STORE) clip playing.

The preset I'm playing wiht is Mago's MCE.  I'd like to squeeze 
another couple of multi-functions out of a couple of controls, if 
possible.

Any help much appreciated.

Cheers
David

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, 
Regards,
Mago

Thanks for the emulation info, Mago, very helpful.
