The new UMR2 (Universal MIDI Retrofit) adds MIDI input/output functionality to non-velocity-sensitive keyboard synthesizers. Use your vintage keyboard as a sound module that responds to MIDI input or as a MIDI controller that generates MIDI output.
The UMR2 is 100% factory-assembled and supports a wide range of vintage keyboards. It supersedes previous HL MIDI retrofit products including the UMR, CS01-MIDI, VL-1-MIDI, and SKM kits. Installation information is being posted at the UMR2 forum by user request. Please join the forum to discuss the installation for your keyboard model.
Example installation guides:
The UMR2 is available for immediate worldwide shipment. For more information, please visit the ordering FAQ.
