This instrument definitely has a lot of potential. However lack of Mute and Solo buttons is a bit disappointing. It would be great if each knob could be reset to default state. Double clicking sets some of them in a strange position. Also I've found two bugs:
Snare Drum Pan knob doesn't work.
Cymbal Tone knob doesn't work.
Overall it's a stable, lightweight piece of gear with very analog (not boring) sounding drums.
The drums are really clean and have a nice warm sound. there is a nice variety of sounds to choose from and they have some nice modulation. The sub-oscillator is really good for a lot of genres and sounds just as fantastic as the rest of the sounds, the fact it's all synthesis surprises me as it takes up little CPU for me.
my only gripe is that the Snare and Kick's pitches can't be controlled, but that's a minor thing.
Definitely good for those who want nice warm sounds, wanna make some old-school hip-hop or techno.
