The spec sheet appears sparse, and while the MIDI implementation for the 707 and 101 is limited, there is more than that PDF.
There are 3 ways to use MIDI to control parameters.
- CC mappings per the spec sheet
- Knob Assigns and then using CC81-84 to control Knob 1-4, there are parameters here that are in neither CC nor Matrix
- Use one of the possible matrix sources that are accessible via MIDI to
control a destination parameter
- Possible sources include CC numbers, sys-ctrl1-4, TODO the rest
What you cannot do:
- You can not control individual partials over MIDI unless through the matrix
- For instance, some partials are not in a matrix's destination, or (and this
- is hard to explain in words, but idea from Ben Coe) creative uses of Step
- LFO values as the source with neg/pos depth, and you use the MIDI command to
- iterate the LFO steps.
- TODO more
Sanity checks:
- There are default matrix source/destinations in the Init patch that you should double check.
- If you change a matrix in advanced mode, the simple mode will only show the values for the first partial. I lost quite a while trying to figure out why sys-ctrl1 was changing vibrato even when the simple menu showed no matrix for it. Turns out partials 2-4 were still matrixing sys-ctrl1 to LFO Pitch Depth.
