Cool

I did not like this synth at first. However, I tried it again after a while last night after setting up rtpmidi and using core midi and a keyboard midi controller to control this synth. WOW, I was able to make some sweet bass!

I tried to get the same sounds in-app but I just couldnt. My midi keyboard will allow me to go four octaves lower than the in app keyboard does and that has made all the difference for me.

I would suggest a future update to increase the range of the in-app keyboard.

I see this synth supports midi CC for cutoff and resonance, but it would be cool if maybe it were possible to midi-learn other parameters. (it might be interesting to say, use a sequencer to change waveforms or to LFO the ratio, etc., this is my first real experience with FM so I dont know).
