Bc2000 (for the BCF2000 & BCR2000)

Good day,

I've taken a look around the group since recent membership and let me tell you, it renews my faith in humanity to see there are still people with brains out there.  Nice little community.  I, on the other hand, use and intend to use the BCF in much simpler fashions, yet maybe they still present new challenges.

I have some experience with SysEx messages and controlling various devices with them.  I am wondering just how one can program a momentary button, say those atop the bc's, to latch on and off.

What I am asking seems simple, but lets get deeper...  Say I want to send a SysEx message from that button to turn a function to "on".  I then have to send a slightly different Sysex chain to turn that same function "off". (changing one bit of the hex)  Let us also say that the device controlled by the BC only accepts input and does not feed any signal back to the BC.

Can I do this with the same button?  Can the LED on the button correspond?  What happens if I turn the BC off and then on again, and the controlled device hasn't changed?

Let me know your thoughts...

Get Mark's editor from his website (mentioned in the files area)
Get the BCL (Behringer Control Language) while you are there.
Have a read of my SecretBC.pdf , again in the files area.

The code you use is
$button 33
.minmax $23 $12
.default $23
.mode toggle ; for latch or 'updown'= momentary
.tx $F0 ... val .. $F7

"val" is the current value assigned to a button, encoder or fader and will be
substituted in the sysex message
On - the max value
F0... 12 ... F7
Off - the min value
F0... 23 ... F7

You can repeat 'val' or use other 'val' types (bits of the 14bit data the BC
uses)

$button 33
.minmax $0023 $3F14
.mode toggle
.default $23
.tx $F0 ... val7.13 ... val0.6 .. $F7

On - the max value
F0... 7E ... 14 ... F7
Off - the min value
F0... 00 ... 23 ... F7


> Can I do this with the same button?
Yes if you can organise the sysex to fit.
It can't do different lengths of sysex for example
Not possible
ON
F0 41 23 34 F7
OFF
F0 41 23 34 13 56 F7


> Can the LED on the button correspond?
The LED matches the state of the button.

You can change patches and the BC will remember the state of all the other
patches, but when you power on the BC, it loads the default into the value of
the button

Hope this helps

Royce, 

Definitely helps. I have found the BCL and secrets. The language reminds me something of a cross between JavaScript and the old Hayes modems. 

If my "project" here works out, we'll have another audio item that can be manipulated with the BC. It's a Studio Technologies StudioComm 78. Made for monitoring 7.1 surround. Most of their products use SysEx messages to control them, not to mention beautifully written manuals that tell you every detail of the operation. Worth checking out if you're into audio and MIDI. 

Where the proprietary controller may be "better" than using a BC, its pretty expensive and I picked up the 78 for near pennies on a whim. We already use a BCF in our studio with Apple Logic. The BCF's 8 faders might be nice to adjust all 8 channels of the 78 on the fly, rather than the controller's big knob and push buttons. (It is certainly easier than entering in the sysex from midi-ox!) 

Hope to get some presets made up soon. 

Thanks, 
Eric
