Sonic Charge has released Cyclone, a complete Yamaha TX16W sampler emulator in VST and Audio Unit formats.
Heres what they have to say about it:
Cyclone is a true low-level hardware emulator. It simulates all the important circuits of the Yamaha TX16W, including the main 68000 CPU, the properietary Yamaha DSP circuits, the 12-bit sample memory and the 400kHz non-linear DACs. Cyclone not only looks like a real TX16W, it sounds like a real TX16W and it runs the exact same software as a real TX16W.
That last sentence is worth elaborating on. We have not merely created a new virtual instrument with a vintage sound, neither is Cyclone an updated version of Typhoon. Cyclone features a full 68000 emulator that runs the exact same version of Typhoon that was released 14 years ago. This implies that using Cyclone will require a bit more effort than your average modern virtual instrument. But this can also be a very rewarding experience. Regard Cyclone as a time travel portal to an era from the past. The era of the monster dinosaur samplers.
