Elektron Analog Four MIDI implementation

The MIDI implementation of the Elektron Analog Four: what it answers to, and the 229 controls it offers, on firmware 1.56.

At a glance

Firmware: This page describes firmware 1.56.
MIDI channel: Any one of 1 to 16.
Parts: Synth Track, 4 of them: each on a MIDI channel of its own, taking notes and controls.
FX Track: on a MIDI channel of its own, taking controls.
CV Track: on a MIDI channel of its own, taking controls.
Performance: on a MIDI channel of its own.
Voices: 4, shared by the parts that play notes.
Note range: Not recorded.
Velocity: Sent and received.
Aftertouch: Answered, of a kind its documents do not say.
Pitch bend: How far it bends is not recorded, and the range can be changed.
Program change: Received and sent, with 128 presets.
MIDI clock: Sent and received.
Start and stop: Sent and received.
Control change: 72 controls, in the tables below, 14 of them with a fine half on a second controller number.
NRPN: Supported. 225 of the controls below have one.
System exclusive: Supported.

Controls

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

How they were read

User manual (112pp), OS 1.56: pp. 11, 16, 28-29, 35-36, 38, 58-61, 64, 82, and the CC and NRPN tables of APPENDIX D: MIDI at pp. 98-106, which is where every number here comes from.

THE MIDI APPENDIX IS D ON THIS INSTRUMENT. On this maker's Digitone, Digitakt and Syntakt it is APPENDIX B and on the Analog Rytm MKII it is C; here A is the synth track's parameters, B the FX track's, C the CV track's and D is MIDI. The letter is worth saying because a pattern that matches nothing reports success.

THE APPENDIX PRINTS 255 ROWS IN 28 TABLES AND 229 ARE BELOW. It has no numbered sections - no counterpart to the Rytm's C.1 to C.8 - but two levels of heading instead, a flush-left section and a centred caption over each table, and a table that runs over a page break repeats its caption and its header row. Six sections and 28 tables; every table holds ten rows, one for each of the ten DATA ENTRY knobs, except the four on the first page.

THE 26 ROWS NOT CARRIED ARE ROWS THE APPENDIX DOES NOT NAME, AND ONE IT PRINTS TWICE. Twenty-five rows have an empty parameter cell: the knob exists and the appendix publishes nothing to call what it reaches. Twenty-one of them carry an NRPN MSB and nothing else, so there is no address to carry. The other four carry a full NRPN address with no name at all - the DELAY's knob C at NRPN 2/52, and the REVERB's E, H and I at 2/64, 2/67 and 2/68. Those four are numbers this format cannot hold, because a control without a name is not something a panel can offer a player, and they are recorded here rather than invented. The twenty-sixth is Track Level, which the appendix prints in two different tables, CC 95 with NRPN 1/100 in both. The two agree, so one control carries it.

EVERY NUMBER WAS READ TWICE, BY TWO METHODS, AND THE TWO AGREE ON ALL 255 ROWS. One reading cut each line at the column offsets its own header row gave; the other clustered glyph spans into rows by their top edge, assigned each to a column by its left edge, and decided what kind of line it was looking at from the type size and colour rather than from the words. Neither saw the other's output. They agree on every field of every row with one exception, and the exception is the maker's text layer rather than its page: the AMP page's Pan comes out of the first method as Pa n. The second reads one span 14 points wide, and the Keys' manual - a different typesetting of the same table - prints Pan. This maker's text layer splits characters on every manual here, so Pan is what is shipped.

NRPN REACHES FAR MORE OF THIS INSTRUMENT THAN CONTROL CHANGE DOES, which is unlike the Rytm, where every control has both numbers. Of the 229 below, 225 have a complete NRPN address and 72 have a controller number, so 68 have both: 157 parameters can be reached by NRPN and by nothing else, and four by control change and by nothing else. The appendix does not say to prefer either, so midi.nrpn records that both are supported and the asymmetry is stated here instead.

THE FOUR WITH NO NRPN ARE TWO DIFFERENT FACTS, and the appendix distinguishes them by leaving a cell empty in one case and printing a dash in the other. Modwheel and Breath Controller carry a dash in both NRPN columns: the maker is saying there is no such number, which fits parameters that are MIDI's own CC 1 and CC 2 before they are this instrument's. The two oscillators' PWM Speed carry a dash in neither - their NRPN MSB says 1 and their NRPN LSB cell is simply blank, where the run of numbers around them would give 8 and 28. That is the maker not filling a cell in, which is different from the maker saying there is nothing to fill in, and the two are not run together here. Both readings preserved the distinction independently.

THE NRPN BANK IS THE PART, which is how this instrument avoids the ambiguity the Rytm has. Bank 0 is the performance macros, 1 the synth tracks, 2 the FX track and 3 the CV track. Exactly one controller number carries two meanings in the whole appendix and it is the duplicated Track Level, the same meaning twice - so, unlike the Rytm's 26 and the Syntakt's 28, a sender using control change here needs no part to know what a number does.

THE HIGH-RESOLUTION PARAMETERS ARE THE ONES WITH A CC LSB, and there are fourteen: the two oscillators' Pitch, the two filters' Frequency, the four envelope and LFO Depths, and Modwheel and Breath Controller. Elektron does use the MMA's LSB = MSB + 32 for all fourteen here - 16/48, 17/49, 1/33 - which it does not on the Rytm, where the fine half of 109 is 118. The appendix marks them a second way, by printing "(0-127)" after the NRPN LSB value on exactly those rows and leaving it off the others.

THE MAKER'S OWN SLIPS, REPRODUCED AND NOT TIDIED. The first table's caption reads PERFORMANCE under the section TRACK PARAMETERS, where the MKII's and the Keys' manuals both read TRACK; the group below is named after the section, which two of the three editions agree on. The COMMON table has no section heading of its own and falls under MODULATION PARAMETERS, which is plainly not what Track Level is about; it is the duplicate, so nothing below depends on where it sits. One parameter is printed CV A Note Slide time where its nine neighbours capitalise every word. The synth track's filter envelope is captioned ENVF and the CV track's, at the same block of NRPN numbers, ENV1. The synth LFOs' rows read Destination A and Depth A where the FX and CV LFOs' read Destination 1 and Depth 1.

SEVERAL RUNS OF NRPN NUMBERS SKIP VALUES, every one of them against an unnamed knob except two. OSC 1 runs 0, -, 2 to 7, -, 9 and OSC 2 runs 20, -, 22 to 27, -, 29, so 1, 8, 21 and 28 are never printed; the gaps at 1 and 21 are the unnamed knob B, and the gaps at 8 and 28 are PWM Speed, which is named, has a controller number, and has no NRPN LSB cell filled in. The NOISE table prints three of ten. Each CV table runs seven consecutive values and then three dashes. Between tables, the FX track uses 0-9 and then jumps to 40, and ends at 69 before its LFOs start at 80. None of that is repaired here: an absence is recorded as an absence.

NOT RECORDED:

values, bands and defaults, which this appendix does not give, so every control below is continuous by derivation;
what note range the instrument answers to, which no page states - the panel's [KEYBOARD] keys "span one octave and one note" over selectable octaves -5 to 5 (p. 36) and the multi map covers "the 128 keys of the entire MIDI keyboard range" (p. 60), neither of which is a statement about what sounds;
which kind of aftertouch is answered to, since the manual says only that parameters may be assigned "to the MIDI after touch command" (p. 35);
and how far pitch bend bends, which is not a fixed amount on this instrument but whatever the bend menu's assignments make it.
