Controls

In the order the definition gives them, by group. Under each control is the name a program calls it by, once pymidiinstrumentdefs.load("moog/subharmonicon") has loaded them.

Where these facts come from

Source documents

How they were read

User manual, 58 pages: MIDI OPERATIONS at pp. 42-44, which is the manual's complete control-change table; tempo and MIDI clock at p. 25; and the specifications at p. 57. Every band and every default from that table is quoted as it prints them.

AND THE FIRMWARE v1.1.1 UPDATE DOCUMENT, five pages, published inside the firmware package rather than beside it, which carries v1.1.0's release notes as its last two pages. One control here comes from it and from nowhere else: CC 91, keyboard note priority, with its own three-band table, on the notes' own p. 4. The manual's table does not list CC 91, and that document says why: "Previously, MIDI CC 91 had no effect" (release_notes p. 4). It also records three things the manual cannot, each marked where it belongs below: that this instrument answers to pitch bend at all, which it did not before v1.1.0; that MIDI notes received while a sequence runs now transpose the sequence rather than playing over it; and that the highest pitch it will play unquantised became a C where it had been a C sharp.

NOT RECORDED: polyphony and velocity, which neither document states, and the contents of the SysEx files that set channel and transport, which Moog publishes separately.
