New UMR2 MIDI retrofit inventory arrives at the warehouse today and begins shipping later in the week.
The Oberheim OB-Xa is a classic synthesizer that can be retrofitted for MIDI input/output via the UMR2. Highly Liquid Forum user Mondovermona recently posted photos of his UMR2 OB-Xa MIDI retrofit project.
The UMR2 has been used to add MIDI input/output to a wide variety of synthesizers, including vintage analog gear like the Teisco SX-400. Highly Liquid Forum user Lackan110f recently shared his Teisco SX-400 MIDI retrofit project and posted a MIDI-sequenced demo on YouTube.
