- Multiple UI modes to play with your sounds
- 10 steep, surgical 48dB filters (1 LP + 8 BP + 1 HP) with filter feedback
- 4 Filterbank model configurations

### 5/5 — Amazing app

*2025-05-11*

Yet another amazing app from Bram Bos and Hainbach. Bought immediately and am loving it. I saw somewhere Hainbach reading a Boost toggle for the feedback which I am very excited about. 

I am also hopeful Bram will consider adding a simple Invert toggle next to the Sync toggle to invert the polarity of the wave in Cycles mode. I am using this a lot for bus processing and it would be nice to have the same speed wave with inverted polarity applied to different busses, so as one goes high the other goes low 

Other small requests : 
1. extending the Pace range to be even slower. It is not currently slow enough for some applications (ambient music, etc)
2. indicating the length of the current Pace setting (in msec/sec or beat divisions when synced - see nembrini audio ARdelay plugin for a good example)

### 5/5 — A live performance manipulation device

*2025-04-13*

An iOS Music App that takes the uniqueness of the platform / device into consideration and its functionally unique interface to give the user a canvas for sound manipulation… what a concept! 

Brilliant app, well done. Another great collab by Bram and Hainbach. Just perfect to play live with.

### 5/5 — Awesome

*2025-04-10*

Great, as expected with this collab! Instabuy! Bram, please consider porting some more of your devices to Mac! i know its a lot of work etc, but some of your plugins are essential to me, and i would love them on Mac!! would buy again!
