There are many tone generators in OASYS, yet KORG dropped its production, and went to develop KRONOS. Better, bigger memory and faster processing, more polyphony. THey are all workstations. Unlike Yamaha, which started to partially drop the concept of Workstation-instrument. Montage and MODX are live-performance instruments compared to other synths, yet they can become workstations once connected to a PC 😊
