In the early 1990's most synth manufacturer's quest to use digital forms of synthesis to re-create acoustic sounds (as well as analog sounds) led to an onslaught of rather boring instruments. Among the mob of digital synths some stood out such as Korg's M1, Roland's D-50, and Yamaha's SY85. Fading away were the days of Yamaha's FM-synthesis, replaced by Advanced Wave Memory (AWM2). Throughout the 1990's Yamaha used AWM2 in many of their successful products because of its high sonic quality and advanced synth-like editing features. The SY85 was a powerful workstation keyboard capable of some great sounds and full arrangements.
It's a 16-part multitimbral MIDI synth with a nice 61-note keyboard designed to be the main keyboard in your MIDI studio, with tons of sounds and sequencing features built-in. It has a long but narrow 40 character x 2 line LCD display and a 5x5 mode selection matrix which enhances operation by allowing fast easy access to any of the SY85's modes. In addition to pitch & modulation wheels and dual output level controls, the SY85 has eight slide controls that can be used to control a range of parameters while performing for expressive real-time power. Best of all it's got multi-mode filters and a dual-effects processor with chorus, flange, reverb, delay, exciter, parametric EQ, echo, ring modulation, leslie, distortion, etc. The effects can be used in series or parallel, and there are 4 busses to route sounds through them. Other features include a 3.5" floppy disk drive, external memory card slots and two assignable stereo outputs.
