With b-step you program your melodies in a few seconds and you can't hit a wrong note. b-step is designed for improvisation and easy live use. You can use the default chord set or easily design your own.
The sequencer comes with native support for one or two Novation launchpads. Mouse control is easy, but if you have a touchscreen using b-step is even easier!
