RepeeteR is a MIDI processing unit that records and loops a played fragment of 1/2/4 measures. The previous MIDI loop still plays (and loops) after you hit the "Record" button, the actual record starts on the first MIDI event played and runs 1/2/4 bars, and gets looped immediately - so you continue playing to the new loop.

Additional Features:

• Fractionally erase and punch-record onto existing loop using still same one button.
• Auto-transposing supported (you have to play a 3-noted chord to have the keytone recognized and the loop immediately transposed).
• Use two additional MIDI controllers: to halve the loop and to fade in/out using output velocities.
• Two MIDI channels to output: the play-through and the record+loop - to drive two synths.
