Best rhythmic gate

Best rhythmic gate

Amazing sound and creative possibilities. It’s well beyond the other sequenced gate offerings on iOS. The per-step filter, resonance, and drive settings make all of the difference. Very inspiring to use and can make more space in a mix as well. I use this on pads a lot, or any time I want to create some space and groove.

The presets are also very usable. It’s for way more than just trance, very inspiring, can create forward movement and bounce. It even has swing! Worth every penny.


Another iceWorks lovely

This app is bomb like all iceWorks apps in my humble opinion! I own them all and they all have their unique strengths and sounds and never seem to overbog when using multiple auv3s.

Bloody Incredible

I'm still getting my head around Koshiba's subtleties but one thing that could be changed for the better is the rate selection. It's a sequential selector, forcing me to audibly create undesirable audio artifacts by forcing the user to 'step though' undesirable rates till you hit the desired rate. The rate control would be better if they were directly selectable.
