Source: Polyend, Medusa Manual (web manual, https://polyend.com/manuals/medusa-manual/, current for firmware 4.0.1), section CC Chart; and Polyend, Medusa Manual Addendum, firmware 4.0.1 (Medusa_Manual_4.0.1.pdf, https://polyend-website.fra1.digitaloceanspaces.com/wp-content/uploads/2023/11/01084147/Medusa_Manual_4.0.1.pdf): control change 3 digital FM algorithm, channel per voice, channel 9 analog voice in digital FM mode. Rows marked changed in firmware 4.0 (glide 5, envelope 2 amount 39, sustain 64) follow the current chart. Envelopes 4 and 5 (filter and amp) have no target row in the chart; control changes 81 and 89 are not listed. The chart labels oscillators 1 to 6 without saying which are analog or digital, and does not explain the U tuning rows. If an LFO or envelope is set to send control changes, its own knob control changes are unavailable. Control change input must be enabled in the Config menu. Channel per voice channels: Mono 1, P1 1 to 3, P2 and digital FM 1 to 6; control changes stay synth-wide. Pitch bend, modulation wheel (control change 1) and channel aftertouch drive the pad's X, Y and Z targets. Program change 0 to 63 selects bank A and 64 to 127 bank B (not a slider here). The Medusa has no NRPN. Panic sends Note Off, All Notes Off (123) and All Sound Off (120); the addendum says both are respected.
