Hi Nic,
I need some help. On my ewi I have this contact button that now sends a continuous stream of cc 64. I want to convert this into a toggling cc 66, when cc 64 = 127 is reached.
Actualy I could do the toggling in my daw with pizmidi. But maybe you have some clever way
I am using streambyter in midifire.
Tia, Alfred

Hi alfredr, This will do that: IF LOAD
# K: CC+chan, CC64, CC66
ASS K0 = B0 40 42
# assume CC66 starts at off
ASS L0 = 7F
END
# check if CC64 is at 127
IF M0 == K0 K1 7F
# toggle CC 66
SND K0 K2 L0
IF L0 == 0
ASS L0 = 7F
END
IF L0 == 7F
ASS L0 = 0
END
ENDRegards, Nic. |

Hi Nic,
It took me some time to comprehend what you did there. Wow streambyter 2 is advanced :-)
Thank you, Alfred

Hi Nic,
There was a little problem with the code. Only the first time it works. After that cc66 is always 0. I rewrote the toggling part like this:
IF L0 == 0
ASS L1 = 7F
END
IF L0 == 7F
ASS L1 = 0
END
ASS L0 = L1

Good find! I've been bitten by that one many times before. Can't teach an old dog new tricks.
Edit: What I should have done to toggle is use the ^ (XOR) operator:
L0 = L0 ^ 7F
No need for IF clauses...
Regards, Nic.
