Yeah it seems that the VCO level to the Bass’s filter is a little too high, I think the Keys has the same filter but it seems that it is not being driven so hard, resulting in a more liquid sounding resonance, on the Bass it sounds a bit stiff IMHO.
Still, it is very much a cool thing in its own right, and besides I am going to make a breakout for external filtering etc, so can get around it. For non acid type bass though it is pretty nice, can even get a little Juno-ey at times.
The Beats is brilliant, even if it only had the kick, toms and hats, the other sounds are ok , but the kick, toma and hats are superb.
Not delved into the Keys much yet, seems pretty versatile though, and again for the price bloody brilliant.
