How they were read

User manual (124pp), the edition Arturia names 4.0.1: pp. 3, 18, 79-81, 83-86, 88, 90, 108, 113-117.

The control-change map is section 16.2.5, "MIDI Control Change Messages" (pp. 116-117), introduced as "Here is the MIDI implementation chart:" (p. 116) and printed in three columns, Section | Parameter | CC. It holds 41 rows and every one of them is here. It prints no values, no band boundaries, no 14-bit pairings and no NRPNs, so each control carries the maker's own name and its number and claims nothing else. Nor does the manual state a controller's range anywhere: the string "127" does not appear on any of its 124 pages, in either extraction mode, so the 0 to 127 every control here spans is the MIDI specification's and not this document's. Arturia publishes no MIDI implementation chart for this instrument either, so the user manual is the whole of what its maker documents about it.

A control's label is the chart's parameter, prefixed by the chart's own section word where the parameter alone would be ambiguous: the chart's columns read "OSC 1" and "Tune", so the label reads "OSC 1 Tune". Group names follow the same sections, with one exception named in a comment below.

Both directions, for every charted control: "Incoming Control Change messages are always accepted, unless the MiniFreak is currently in communication with the MiniFreak V software" (p. 117), and "The Wheel Touch Strip, the Sustain pedal, and most of the front-panel knobs send unique CC messages" (p. 117), which Utility > MIDI > Knob Send CC can switch off. So no control here needs a direction, except the one that is not in the chart.

ONE CONTROL IS NOT IN THE MANUAL, and is marked in place: CC 7, volume. Arturia's firmware release notes say of version 2.0.0 "CC7 now controls the volume" (release_notes), and this manual, written for 4.0.0, does not mention CC 7 anywhere: searched for "CC 7", "CC7" and "volume" across all 124 pages. Two of the maker's own documents therefore disagree, one by silence. The release notes are cited for it, it is recorded as received only since nothing says the Volume knob transmits, and the chart's silence is recorded here rather than resolved.

NOT RECORDED, and marked in place:

the note range, since the manual never gives a MIDI note number for anything;
what the instrument does with velocity that arrives over MIDI, as opposed to velocity its own keyboard senses;
the pitch bend range as one number, since Bend Range is a per-preset setting of 1 to 12 semitones;
system exclusive and NRPN, since neither sysex, system exclusive, NRPN, MSB, LSB nor 14-bit appears anywhere in the manual in either extraction mode, and a silence in a user manual is not a statement that the instrument has none - this one exchanges whole samples with its own software over USB and never says how.

Aftertouch is the asymmetry here: "The keyboard sends monophonic aftertouch messages, where all sounding voices are modulated by the same amount" (manual p. 86), while "When receiving external MIDI, the MiniFreak's sound engine is compatible with polyphonic aftertouch MIDI messages" (manual p. 86). So aftertouch is poly, for what it answers to, and aftertouch_transmits is true, for the fact that it sends; the kind it sends has no field, and is in a comment beside the flag. CC 64 does more than the chart says. The release notes, version 2.0.0: "Hold now sends CC64 with value of 1 when Arp/Seq is enabled, and holds Sequencer but does not Sustain" (release_notes). The chart lists CC 64 as Pedals | Sustain and says nothing of the Hold button or of the value 1; both readings are recorded against that control.
