### 5/5 — I love it.

*2026-05-16*

Cool and weird. I own a few from this developer and I think they’re really cool and useful.

### 2/5 — No presets

*2025-05-26*

It sounds great but I am unable to access any presets. It lists KBD.patch_1 ,2 ,3 etc but they all sound the same. I have searched online but am unable to find a solution- it’s a real shame as it does sound good.

### 5/5 — My favorite of bunch
