## Version history (last 4 releases)

### 1.0.3 — 2026-04-14

Fixed envelope duration menu.  Now 1/4, 1/2 and bar options all work properly.

(I've noticed first launch after update sometimes the host doesn't initiate the playhead properly, just relaunch the project again and everything is fine from then on)

### 1.0.2 — 2026-04-13

iPhone now supported

### 1.0.1 — 2026-04-10

Improved handling of tempo changes.  So if you have a bpm-ramp automated, the envelope timing is now more accurate across shifting speeds.

### 1.0 — 2026-04-06

No release notes.
