Ensoniq SQ-R Rackmount Synthesizer

   (0 reviews)

The Ensoniq SQ-R Rackmount Synthesizer was the rack version of the SQ-1 keyboard. This SQ-R came in two version, regular with 24 voices and a Plus version with 32 voices.

The ENSONIQ SQ-R's synthesizer section features 100 high fidelity sounds contained in ROM (Read Only Memory), with 80 additional slots in Internal Memory for sounds you create or edit. Optional RAM or ROM Cards allow access to 160 more sounds, for massive 340 available at once. Each SQ-R sound is created with three digital oscillators that select from 121 sampled acoustic and synthetic waves, as well as ENSONIQ's unique Transwaves™, which possess great harmonic complexity and timbral motion.

The complement to this wide palette of tonal colors is an on-board programmable digital effects processor that adds dimension of breadth and depth to each SQ-R sound. Various reverb, chorusing, flanging, delay, distortion, and even roto-speaker programs are provided with dynamic control over many settings.
