Not true.
Behringer, for what ever reason, have limited their own equipment to
.easypar and the simple sysex on the buttons with their learn method
where the firmware code inside the BC2000 allows much more.
$encoder 34
.minmax 0 127
.default 1
.tx $F0 $41 $10 $00 $6B $12 $10 $00 $21 $1E val cks-1 6 $F7
.resolution 96 96 96 96
.showvalue on
.mode bar
$encoder 35
.minmax 0 127
.default 1
.tx $F0 $41 $10 $00 $6B $12 $10 $00 $22 $1E val cks-1 6 $F7
.resolution 96 96 96 96
.showvalue on
.mode bar
Here are a couple of encoder setups to show you what I mean.
These control my Fantom X
There are a few checksums to choose from
cks-1 <arg>
- a bit confusing in the German documentation but it works for Roland
and they say
byte aa + bb + cc = sum
sum /120 = quotient with remainder
128 - remainder = checksum
I'v seen it calculated differently using subtraction instead of
addition and that is what the Germans say
subtract all the values and the bottom seven bits is the chksum
and it works.
cks-2 <arg>
like cks-1 but adds the values instead
cks-3 the bytes are XORed together
The val can also be broken up into nibbles allowing for a greater max
and min (ie negative) value
You can write the numbers in decimal
.tx $F0 $41 $10 $00 $6B $12 $10 $00 $21 $1E val cks-1 6 $F7
"val" is the value of the encoder
"cks-1" is the Roland checksum
the 6 at the end is - "what position in the sysex message do I start
at when I calculate the checksum"
Note that there is a bug (in my BCR2000 at least) if you get the
BC2000 to send back the sysex you will get the line
.tx $F0 $41 $10 $00 $6B $12 $10 $00 $21 $1E val 6 $F7
which is still a valid sysex, but it is not what you need as the
checksum is missing
To write the .tx stuff use the LEARN setting in the Birdie editor.
There are a few limitations to the Birdie editor and he has written to
me saying that he is not going to develop the editor any further so I
am writing my own (I would prefer to be playing music).
Currently it is just a BC2000 Script editor that then wraps the sysex
around each script line and sends it to the unit.
I use it as a text editor (like the one I am use to write this) and I
cut and paste a finished encoder or button script and then change what
I want.
I might build a graphic editor but the text bit is woking well.
If that is any use to anyone let me know and I'll neaten it up and
post it.
Check out the German site metioned in previous posts. Pass it through
Bablefish or Google to translate it. I don't speak Gearman (shame on
me as most Germans speak great English) and I got all the info through
Google translation. A lot of it doesn't translate too well being
technical stuff, but worth the effort.
All the best
Royce
