| ====== 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. |
