Title: MIDI CC Commands
Post by: Lunatic Sound on August 01, 2018, 12:22:08 pm

Here´s something else interesting, I found:

The knob controlling the volume of the OSC´s Waveforms and also the knobv controlling the Mixer send MIDI CC on two, umm, whats the name, channels(?). I don´t mean MIDI Channels, but for example OSC1´s triangle waveform send MIDI CC as MIDI CC 10, linearly rising to 127, and on MIDI CC 42, jumping around quite wildly. I suppose, that is to enable more than a 127 steps resolution?

It created some really unexpected behaviour on other synths, when I used the MatrixBrute as a Controller for those, thats how I found out...

I really feel like a scientist, sometimes, discovering more about this marvellous, poorly documented beast.

Those are standard assignments for 14-bit control messages. Try disabling "14-bit automation" in the MIDI Control Center.

See https://www.midi.org/specifications-old/item/table-3-control-change-messages-data-bytes-2 -- note the MSB/LSB pairs for the CC messages.

I thought so myself after reading around.

Intersting! Thank you!
