idea - MOD KEY Keys2CCs Mode #45
Description
Any thoughts/suggestions on this?
SETUP CTR > MOD KEY: KCC (Keys2CCs mode)
- if MOD key is pressed with no other keys held, send LEVEL CC = 127
- While MOD key is held
- if another key is pressed, send (LEVEL CC + offset) = 127
- if another key is released, send (LEVEL CC + offset) = 0
- if MOD key is released with no other keys held, send LEVEL CC = 0
notes
- to use MIDI Learn, first hold MOD, then enable MIDI Learn, then press key
- key sequence is significant; for example, if LEVEL CC = 102 (+=press,-=release):
- +MOD+RH1-RH1-MOD = CC102=127,CC104=127,CC104=0,CC102=0
- +MOD+RH1-MOD-RH1 = CC102=127,CC104=127
- +RH1+MOD-RH1-MOD = CC104=0,CC102=0
- +RH1+MOD-MOD-RH1 = (nothing)
- setting LEVEL CC to 102 uses a relatively “safe” range of non-reserved CCs (102-117)
CC offset map
| Key | CC offset | Key | CC offset |
|---|---|---|---|
| RHs | 1 | LHb | 8 |
| RH1 | 2 | LH1 | 9 |
| RH2 | 3 | LH2 | 10 |
| RH3 | 4 | LH3 | 11 |
| RHp1 | 5 | LHp1 | 12 |
| RHp2 | 6 | LHp2 | 13 |
| RHp3 | 7 | LHp3 | 14 |
| specialKey | 15 |
benefits
- enables up to 16 unique CC trigger messages with quick one-shot fingerings
- friendly to synths/DAWs with MIDI Learn functions
- possible to send messages as momentary on/off or one-shots for toggles
- infinite combinations of complex multi-key sequences possible with host scripting
- receiving host can detect relevant press and release events
- could be combined with PbUp/Dn or other sensors to intuitively adjust values
- could be useful for testing/troubleshooting hardware
- does not require modifying NVRAM data structure for storing settings
use case examples/ideas
- patch changes - faster than “fastpatch” :-)
- control effects like reverb & delay
- toggle internal patch settings/features
- host transport start/stop / looper controls
- quick host-side transpose (octave/semitone)
- host-based harmonizer/rotator
- “drum machine” mode
- sheet music / chord chart page-turner
- lighting cue triggers
