MIDI effects

MIDI effects work on notes, not on sound. They sit before the instrument, so they decide what
it plays: which notes, when, and how hard. They belong to a Notes Orbiter (an Orbiter that plays notes with a synth or the Sampler, not an
audio).

Move over the rack to follow one note.

Generators make notes; MIDI effects reshape them; the instrument plays the result.

Generators and MIDI effects

There are two kinds, and the order is always the same:

1. A generator makes notes on its own, so it leads the chain: the Drum sequencer, the
   Arpeggiator, Step sequencer, Axis notes. A dimension has at most one.
2. MIDI effects reshape the notes that reach them, from a generator, the keys, MIDI hardware or
   the piano roll: Note echo, Velocity, Note length, Random, Chord, Scale, Pitch. The MIDI
   monitor changes nothing: it shows what reaches it.

Echoes and repeats land exactly on the beat.

Adding one changes nothing until you move something: turn it up while you play. Scale holds the notes to the Orbiter's key as soon as it has one. The generators are the exception: the Step sequencer plays as soon as you add it, and the Arpeggiator as soon as you hold a key.

Every MIDI effect

Drum sequencer

A pad controller for drum patterns: up to 32 beats, real-time FX.

Arpeggiator

The notes you hold, one after the other in time: thirteen orders, octaves, a rhythm grid.

Step sequencer

Draw a line of up to 32 steps and it plays in time: 16 patterns, chance, even rhythms.

Axis notes

Play melodies by moving: an axis walks up a range of the key and each new note lands on the beat.

Latent space

Play loops made by trained models: drums or a melody that morph as the axes move.

Note echo

Each note again after a delay, quieter or louder, climbing or falling.

Velocity

Reshape how hard each note plays: curve, floor, randomness.

Note length

A new length for every note, notes on key release, or a chord held until the next.

Random

Move notes up or down by chance, in octaves or in the key.

Chord

Each note becomes a chord: a set for every note of the octave, or built in key.

Scale

Keep the notes in a key: outside notes move to the scale, or are not played.

Pitch

Transpose in semitones or in degrees of the key, and keep the notes inside a range.

MIDI monitor

See the notes, chord, bend and every message that reaches this point; two of them show before and after.
