Um, the KT76
Ensoniq always made workstations with only a few exceptions like the original VFX.
The KT88 followed the TS series, I'm not sure if it continued with the Transwave
engine or not but it's definitely sample-based. It does have resonant filters which the early Transwave instruments lacked.
I listened to Hatfield and the North at Rainbow. They were very wonderful and they made my heart a prisoner.
