bcr steps is a pretty sweet eight-step sequencer and arpeggiator, with features that control velocity, duration, delay, modulation and bend for each step. It handles MIDI input and output and can (with great advantage) be used with a MIDI controller.

Thanks to Joakim Eriksson for the DKnob!
Thanks to Brian Rzycki for bcrtool, and to the guys at sequencer.de for their BControl Sysex Tokenreferenz, great work (just wish my german was a bit better...).
And final thanks to Behringer for making the BCR2000.
