Bc2000 (for the BCF2000 & BCR2000)

Royce,

Thank you very much!  And I get how it works!  (I take it 96 "pulses" per rotation is the actual resolution of the controllers, so you add 0x7f to the value for each "pulse".)

So, given one thing I thought wasn't possible actually is, I guess I should ask about other things I don't see a way to do.  Here's two other things I thought it'd be nice to be able to do, that I don't know how to:

1. (I think these are often called Radio Buttons in GUI terms.)  If I've got three (or more) buttons in a group set up to send sysex strings, can I get the light to turn on for the last button of the group pressed, and the other lights off?  As a specific example, I've got three buttons selecting a sawtooth, pulse, or triangle wave.  I've been imagining it might be possible to use an .easypar with an unused controller, but each button would have to respond to a different value for "on".

2. Can I affect the range of one encoder based on the setting of another?  (Particular case: I Change the octave of oscillator A, and want the range of oscillator B to be +/- 24 from the value I set for A.)   This one I am extremely doubtful can be accomplished...

I might as well explain the application.  

A full blown editor for a JV-1080 is too large for me to tackle at this point.  But:  A freeware Windows editor for the JV/XP family, called ChangeIt by Jurgen Mossgraber, has a tool called the Virtual Synth.  This tool sends a patch to the synth that is configured a lot like a two-oscillator analog synth, and has on screen controls for the various things you'd typically find in an analog synth (Oscillator wave and ocatve/tuning, ADSR for amp and filter, filter cutoff and resonance, LFO rate, shape, destination, etc).  Of course it sends sys-ex strings for each control.

I've mostly succeeded in putting all those on-screen controls into the BCR.  26 buttons and 28 encoder's worth of control.  It's rather fun. :-)

Anyway, thanks again, to Royce, and to whoever else might reply to this message, plus to all those who bothered to document the BCR/BCF sysex format.

--> Steve
