Great but...

Really nice sounding and versatile FM synth. If you want 6 op FM this is the one to get.
It has some issues however: it crashes on a regular basis -a complete catostrophic one whereby the app just disappears which occurs when using the chaos arpeggiator and altering parameters at the same time. Also the LFOs don't go to a low enough frequency to get decent vibrato and when trying to use them at low speed (or the trem type effect) you get audible thumping in the signal, they also seem to be all or nothing: needs an amplitude control.
It needs a filter envelope, a pitch envelope and (possibly) envelope control of some of the modulator parameters, although you can get control of these via MIDI.
Tip: don't always use it in high definition mode: you can get some lovely lo if basses in 'cheap' mode, especially with a small amount of reverb. added.

Ahead of the curve, but...

Good to see this synth now has Ableton Live. But, it STILL needs state saving under AudioBus, and in-app last setting automatic save. Until it gets those, I can't give it the full 5 stars.

Abandoned app?

Hasn't!t been updated in a year or more. No support worth mentioning, last post in forum over a year ago. In-app store links don’t work so no way to expand beyond very basic free version. A pity as it sounds pretty good but with no way to program it it’s very little use.

iOS11, iPad Pro.
