MauSynth is free(donation) synth by Pekka Kauppila.
The synth can create modern sharp sound, soft pad, etc...
But there is no user presets except mine.
Why you don't create presets for the synth?
I think the reason about it.
1 High CPU usage
If it does not work on your computer, you should decrease voices number and unison number.
2 Unlabeled modulation knobs
UI of MauSynth is Intuitive. OK, I created a picture.

Helpful?
