Synthchaser MIDI Adapter for ARP Quadra – Synthchaser #152

Supply chain issues are finally easing up and I’m able to produce another run of the MIDI Adapter I designed for the ARP Quadra back in 2021. It is the first and only MIDI interface for the ARP Quadra synthesizer! This MIDI adapter is user installable and requires no soldering or permanent modifications to the synthesizer to install (other than perhaps holes to mount MIDI jacks). Simply replaces the existing keyboard electronics board. Provides MIDI In, Out and Through capabilities! Supports aftertouch In and Out (via MIDI In, aftertouch will be applied to the full 5 octaves of lead synth instead of just the upper 3 octaves as limited by the original hardware). Supports duophony in the lead synth section and is compatible with the Quadra’s internal sequencer/arpeggiator.

In this video I show how easy it is to install, and how it allows you to interface with all 4 sections of the Quadra.
