CCStepper

CCStepper is a VST MIDI CC data sequencer plugin, suitable for controlling MIDI capable software (softsynths or effects) or external hardware devices.

CCStepper lets you create up to 8 independent sequences with up to 64 steps each, and can either be synced to your host or triggered by MIDI notes. The step rate can be set from 1/128 notes and up to 32 bars, and various randomization features allows you to create unpredictable sequences.

Freeware for Windows.
