AMPT is a tool for transforming MIDI messages originating from any external MIDI keyboard or other software in a performance or experimental setting. MIDI is routed and transformed in AMPT by linking devices on a virtual canvas. AMPT Filters will offer delay, echo, transpose, and arpeggio. AMPT also works as a MIDI router or loopback.
MIDI Rules is a Rule-Based MIDI Processing Environment that can process (translate, map, convert, filter, trigger, route) MIDI messages. It supports multiple MIDI inputs/outputs, variables (enables state-based processing) and timed/delayed messages.
