Bc2000 (for the BCF2000 & BCR2000)

So I'm in the process of creating a pretty fully implemented patch
(set of them actually... ) for alesis quadrasynths (i'm using a QSR)
and ran into a few issues with offsets in sysex messages. 

I've been using the alesis sysex doc (which is very comprehensive, but
wrong about a few things... go figure...) from their website. I've
been figuring out the commands by watching the output from a software
qsr editor that i know works.

A basic program parameter changenlooks like this:

<header 6bytes><mode/function><sound/page><channel/pot><val><F7>

So for a filter freq change i've got this on a rotary controller:

$F0 $00 $00 $0E $0E $10 $44 $00 $07 val $F7

and it works like a charm.

Now, when I read the output of another parameter change (Vel>Filt)
from the software editor I get <06> in the 9th byte but then it
changes to <07> mid-way through a revolution of the slider in the
software. I know this has something to do with an offset b/c in the
sysex doc from alesis this parameter shows up as having an offset of
-99 (the filt freq example above showed an offset of 0). My problem is
I have no clue what the offset means, or how to use it to program a
single rotary controller in bcman to adjust this parameter fully.

I'd love some help. This is taking a lot of work and when its done
I'll post the whole thing here for everyone. No more quadrasynth
menus! I just gotta get over this hump.

I appreciate you giving this a look Royce

The output I get coming out of my software editor shows at max value:

F0 00 00 0E 0E 10 44 00 06 63 F7

and at min: F0 00 00 0E 0E 10 44 00 07 1D F7 

also my sysex document has this to say about the parameter

offset: -99
limit (max value): 199
bits: 8
bit address:13:0-12:1

Hopefully that'll help. I don't know what half of it means...

Thanks again, Royce. I figured that was the deal but thought that some
of those other variables in the "custom output" menu in bcmanager
might be able to help me out. 

Looks like this'll be going to way of my micron template, then (hhehe
and don't even get me started on that.)

Josh, you are doing a great job. I'm waiting this template, cause i 
have a QSR too. Don't know nothing about Syxex commands, so just my 
moral support for you.
Thanks for this
Cheers

thanks. its close to done. not gonna be 100% but pretty close. mainly
program mode stuff. i'm gonna work on mix later.
