Pan problem

[jrm1]

Turning Osc 2 frequency knob transmits CC10 to my DAW, which is Logic. Similarly if I pan the MIDI instrument in the channel strip, I get the same result in reverse direction. Any idea why?

[jrm1]

Actually, the OSC 2 knob transmits 10 and 42 (#10 LSB -not sure what that is!?)

Least Significant Byte, as opposed to MSB - Most Significant Byte.

This is used for transmitting 14 bit MIDI data.

So it's effectively still CC10 MIDI data (ie pan) when I turn the OSC 2 Freq? Why would it do that?

Those functions can be mapped to the knob. New or used? Maybe a previous owner mapped it that way for that patch? Factory reset?

[jrm1]

Do you mean I can change the CC mapping? I'd like to be able to pan, without changing OSC 2's frequency, but as yet I can't. I'll look again at the manual.

I was thinking of the Little Phatty. My bad. But the Voyager also has pot mapping. See page 58 of the manual.

14 bit MIDI it is.

Classic MIDI is coded over 7 bits, which allows to obtain the usual MIDI CC's 128 values. To get more detailed parameter values, Moog uses another CC to trasmit 7 other bits. The result is 128*128 possible values, which are 16384.
The 7 bits used for the first 128 values are the least significant byte, while the other one is the most significant since its changes lead to bigger value variations.
