A digital Workstation series. SQ-1 is first in this series with the typical architecture of the day. Very nice sounds for 1990 and a simple to use sequencer. Well set up for modulation options etc. Decent Leslie for the day also...reverbs have digital fx anomoles easily heard in the high end in particular. Very cheezy; not as good as Korg's of the same day.
Always verify power supply voltages if problem looks like it could remotely be power supply related.
Syntaur has many parts for Ensoniq specifically. Let me know if you need a specific part from my listings in the parts section that you don't find elsewhere or whatever.
