## What is Oxidzr Sequencer?

Oxidzr Sequencer is a MIDI step sequencer for iPad and iPhone. It makes no sound of its own: it plays your synths, drum machines and music apps, with eight sequencers running at once, each in any of nine modes.

NINE MODES
• Mono: one note per step for bass lines, leads and riffs, with real legato ties.
• Poly: stack up to seven notes on a step.
• Chord: place a root and get a chord in key, from triads to 9ths, with inversions and strum.
• Multitrack: eight drum lanes, each with its own channel, speed, length and Euclidean rhythms.
• Stochastic: a probability generator. Weight the notes, octaves and lengths, and let it play.
• Matriceal: pitch, rhythm, velocity and more on separate lanes of different lengths and speeds.
• Domino: a rhythm layer and a note layer that drift against each other.
• Saga: stages that last as long as you like, with gate types, glide and random range.
• MIDI Player: load a MIDI file and loop any part of it.

NOTES THAT EVOLVE
Give any note an accumulator and it climbs, falls or bounces each time it plays, within the bounds you set. Faded ghost notes show where it goes next.

MODULATION
Every sequencer has eight modulation lanes with their own length and speed. Send them out as MIDI CC, or point them at transpose, velocity, gate, probability or swing.

PATTERNS AND PERFORMANCE
Eight pattern slots that switch on the bar line, a chain of up to 32 links for whole arrangements, and a momentary loop for any 1 to 16 steps. Hold keys on a MIDI keyboard and the arpeggiator takes over; step-record notes and chords with the velocity you played.

PLAYS WITH EVERYTHING
• Standalone, with its own virtual MIDI port, USB, Bluetooth and network MIDI
• AUv3 MIDI plugin for hosts like AUM
• Ableton Link, MIDI clock out, and a metronome with groove loops
• Export and import patterns and projects

## Version history (last 2 releases)

### 1.1 — 2026-11-04

iPhone: with the phone upright, » opens tempo, MIDI out, clock, metronome and Link as rows under the top bar, and undo and redo always stay on screen.

The markers for notes above or below the visible keys now line up with their steps when the grid scrolls.

Poly mode: dragging a note onto a step now adds it to that step's notes instead of pushing them aside.

The piano keys show the root note beside the key, so it's easy to see in any app colour.

Crash reports and anonymous usage statistics now help find problems and show what to improve. No accounts, ads or tracking.

### 1.0 — 2026-11-03

No release notes.
