I spent some time the other day playing with BassLine 2.0. I have to admit I’d forgotten how good a little synth it was. The thing that makes it great is the ability to tweak the sounds with your thumbs on the freq response and envelope pads. It is great fun to use.
Of course now that BassLine has audio copy as well it becomes even more useful and fun to play with and you can integrate it into something far more complex.
