Checked against the Octatrack User Manual, OS 1.40A (Octatrack-User-Manual_ENG-OS1.40A_220204.pdf, SHA-1 d292cf8ce5a4695db83d09948641897ff383a558): identical Appendix C tables. The Octatrack documents control changes only, with no value ranges except the on and off rows. The manual prints no default channels. Arm, note-by-control-change and send-request messages are actions, not sliders. The MIDI-mode mapping (C.8) is not used.
