| | ====== Ideas/Draft for better midi controler integration ====== |
| | |
| | |
| | . |
| | ===== Ideas ===== |
| | |
| | - Allow external control for the transport using normal MIDI CCs |
| | - Allow the mixer to be controled using CCs |
| | - Allow selecting segments in the arranger using 2 CCs (vertical and horizontal) - is that really useful ? |
| | - Allow selecting the current track over CCs, maybe dis/enable record state |
| | - Allow to record Controler movements, in order to articulate midi tracks: expression, velo, portamento, modulation, etc.. |
| | |
| | . |
| | |
| | ===== general ===== |
| | |
| | ==== general workflow ==== |
| | |
| | - make some knobs and slider values (e.g. mixer volume) controlable (how?) |
| | - allow rosegarden to receive midi control messages and send them to the right slider-controls (classes ?) |
| | - make control messages recordable and "playable" |
| | - add an (UI-) interface for setting up common (hardware-) control interfaces. |
| | |

| | ===== implementation details ===== |
| | |
| | |
| | ==== MIDI controler details ==== |
| | |
| | '' |
| | A usual midi control message has 3 Bytes : |
| | - $B0 (where low-nibble 0-F is the channel nr.) |
| | - $00 - $7F (the controler number) |
| | - $00 - $7F (the value (MSB)) |
| | It's possible to send a LSB controler-value-pair for fine tuning additionally. |
