Brain
The brain () works out the key and scale of the tracks routed into it, and its keyboard transposes them in key — live, or sequenced as notes on the brain track.
A fast way to write: sequence a beat, a bassline and one chord, then play or sequence root changes on the brain track. Take leads and drums out of the routing when they should stay put.

Details
- TE’s guide
The brain detects the key and scale of the routed tracks and transposes them musically — the whole song or only some tracks.
- TE’s guide
On the brain track, the keyboard transposes every routed track.
- TE’s guide
Brain notes recorded into its sequence play back as transpositions, so a one-bar idea follows a chord progression.
- TE’s guide
The brain's manual mode lets you set the key yourself when detection gets it wrong.
- TE’s guide
Tracks left out of the routing on M2 are neither transposed nor used for key detection.
- community
In a new project tracks 3–8 are routed to the brain and drum tracks 1 and 2 are not.

The brain has seven scales, shown in this order as major, dorian, phrygian, lydian, mixo (mixolydian), minor and locrian.

The brain's routing is stored per pattern, not per scene.
- TE’s changelog
Arpeggiator notes follow the brain; OS 1.1.17 fixed arpeggios ignoring it.
- checked on a unit · 1.1.33
The brain's is headed with the current key, such as c major, and draws a mini keyboard marking the scale's notes. Manual mode shows a hand and the root and scale fields; auto mode shows a brain head instead.
- checked on a unit · 1.1.33
Link reads a crossed box when off and a two-digit number otherwise; with CC15 at 32, 64, 96 and 127 it showed 02, 04, 06 and 08.
- checked on a unit · 1.1.33
slides in from and shows an in bracket running from the brain to track boxes 1–8, each on or off.
- checked on a unit · 1.1.33
The brain has no filter page; CC32 and CC35 on its channel change nothing.
- checked on a unit · 1.1.33
Over MIDI, CC12–15 on the brain's channel (9) drive its four encoders; CC12 shows manual at 0 and auto at 127.
