### 5/5 — Muy buena, pero..

*2026-03-15, version 1.6*

Genial App, muy buen sonido y posibilidades de creación, pero la última versión (1.4) no funciona en Ableton Live 12, se bloquea. Espero que se arregle en la próxima versión y tendrá 5 estrellas.

En la versión 1.6 se arregla el bug en Ableton Live! Cinco estrellas!!

### 5/5 — real good drumsynth

*2025-10-30*

it’s like if a pedal was an app? in a good way. simple but highly customizable. also recommend jan’s other app - bleep. wish this guy had a team to produce desktop pedals too! they’d be tops!

### 5/5 — Ok well then…

*2025-06-07, version 1.4*

Stumbled on this one - absolutely brilliant ability to create very musical patterns and change sounds on fly. You can get really ambient with this one. Of course Ableton link would be great, but no-one’s perfect… this is an absolute cracker of an app.

### 4/5 — crashes when I try to run the sequencer

*2025-04-02*

In demo mode.   Is the sequencer supposed to work in demo mode or no?  I'm considering buying it but if sequencer doesn't work, will probably wait for a more stabile verison.   Thanks!

### 5/5 — Great sounds

*2025-03-22, version 1.3*

Came out rough and ready but it has gotten much better with latest updates thanks to the super responsive developer. Thanks

### 5/5 — Amazing drum machine and sequencer

*2025-03-09, version 1.0*

Creative, intuitive and powerfull drum machine/ sequencer.
From realistic drum sounds to experimental percussion. Very flexible and creative sequencer! Great app!

## Version history (last 5 releases)

### 1.6 — 2026-03-13

- Fixing a crash that appears in DAWs that have limited MIDI support for AUv3.

### 1.5 — 2026-02-28

- Bug fix: save / load presets via a DAW host.
- Option to provide an alternative MIDI note for open hi-hat sounds. There is only one hihat model, and the sound is open or closed depending on the current decay value. By setting an alternative MIDI note, you can send a different signal to an external MIDI receiver when the hihat sound is open or closed.
- Option to let MIDI channels 2-16 trigger chromatic drum sounds for the respective drum pads 1-15, while MIDI channel 1 will still respond to the MIDI notes of the different drum pads (i.e. the default behaviour). Drum pad 16 can not be triggered chromatically.

### 1.4 — 2025-04-12

- MIDI and bus settings state of the app can be saved in DAWs such as AUM.
- Almost all controls can be MIDI mapped with MIDI learn.
- Drum kit functionality was added. You can now load, save, export, import drum kits.
- Randomize button to generate random drum sounds.
- Option to start/stop the sequencer when the audio unit is run as AUv3 via a host.

- Customize each of the 16 pads as a membrane or cymbal synthesizer.
- Portrait mode for iPhone and iPad.
- MIDI input pad highlighting.
- MIDI learn functionality.

- Allow import of multiple presets at once.
