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/minitaur") has loaded them.

Where these facts come from

Source documents

How they were read

User manual (c)2012 pp. 21-24 for the control-change chart, and THE FIRMWARE v2.1 ADDENDUM BOUND INTO THE SAME FILE, after its last numbered page. The addendum is not a separate document and never was: two pages headed "MOOG MINITAUR FIRMWARE v2.1 ADDENDUM" (addendum) follow the manual, and its corrections are the section headed CORRECTIONS TO THE MANUAL on the second of them.

THE ADDENDUM'S PAGES PRINT NO NUMBER, so it is cited by its own section headings rather than by page, the way a document with no pagination is cited anywhere here. The manual's own folios stop at 30. This file used to cite the addendum as four numbered pages, 31 to 34, which was a count rather than a reading: the manual proper is printed two pages to a sheet, and continuing that arithmetic past the end of the numbering turned its two unnumbered pages into four numbered ones. Established on 2026-10-01 and corrected the same day, from the sheets themselves: the manual's sixteen sheets are landscape and carry two numbered pages each, up to 29 and 30 on the sixteenth, and the two addendum sheets after them are portrait, carry one page each, and are headed but not numbered.

Two band boundaries below are those corrections and differ from the chart, and the addendum quotes the error it is fixing: "TRIGGER MODE - CC 73 (values) 0-42(LEGATO ON), 43-85(LEGATO OFF) 86-127(EG RESET) [was incorrectly given as 85-127 in manual]" (addendum), and "KEY PRIORITY - CC 91 (values) 0-42(LOW) 43-85(HIGH) 86-127(LAST) [was incorrectly given as 87-127 in manual]" (addendum). So the chart leaves 85-86 unassigned for key priority, which is the printing error the addendum fixes - and the widely shared Moog_Minitaur.midnam has it as 85, which is wrong.

NOT RECORDED, and marked in place: the 22 bands of the LFO clock division and the 8 bands of bend up/down, for which the source gives only the first and last. The LSB of EG amount and filter KB tracking are deliberately omitted - see the note above those controls.
