Quasimidi

The company also produced an upgrade kit to expand the capabilities of the popular Roland E-20 keyboard, as well as several ROM cards for the E-20 offering additional accompaniment styles.

The presets and drum sounds eschewed the typical General Midi specification, which was in vogue at the time, in favour of electronic and trance techno styles.

Whereas the Quasar was a two-unit rackmounted box, Quasimidi's subsequent instruments migrated into the desktop & full-size form factors.

Quasimidi also built the Raven, a full size sample-based Virtual Analog synthesizer, which offered a unique sequencer implementation, allowing for the keys to be used both for muting/unmuting and transposition of tracks.

Quasimidi also built a master keyboard dubbed the Cyber 6, which shared the same casing as the Raven, albeit with a few cosmetic differences.
