YAMAHA SY-35 vector synth

via this auction
"YAMAHA SY 35 Digital Vector Synth plus a very rare 64k RAM Card (new internal card battery installed), the original power supply, and a sound editor disk (for PC and Mac / a $29.95 value)

Dual Synthesis Systems
It incorporates two essentially different synthesis systems: AWM and FM. AWM- "Advanced Wave Memory"- is a sampling technology that allows high-fidelity reproduction of digitally recorded "live" sound. FM is Yamaha's proven Frequency Modulation synthesis technology which is capable of creating extraordinarily warm, vibrant simulations of actual instruments.

Multi-Element Vector Voices
Either a 2-element or 4-element configuration. Each "element" is actually an independent sound or "waveform". A 2-element voice combines one AWM and one FM waveform, while a 4-element voice combines two waveforms of each type. Vector control allows the 2 or 4 different waveforms in a voice to be blended and detuned in a variety of ways- manually or automatically.

Vectors Control Level or Detune
The SY35 vector control can be used to control either level or detune along the vertical axis if a 2-element voice is selected, or along both the vertical and horizontal axes if a 4-element voice is selected.

In-depth or Instant Voice Editing
Program complex amplitude envelopes for each element from scratch, choose from a range of preset generic envelopes that can later be edited for fine control, or simply use the original envelopes that are included with each of the SY35's 384 internal waveforms. A range of other voice editing parameters give you extensive control if you want to get serious about programming.

Dynamic Vectors
Real-time manual vector control means unprecedented expressive freedom, while dynamic vectors that play automatically whenever you play a note on the keyboard.

128 Ready-to-play Voices
Although programming your own vector voices isn't difficult, Yamaha has provided a range of 128 superb preset voices that you can play right away with no programming.

Multi-timbre Mode and Built-in Drums
A Multi mode can be used to play several voices simultaneously via the SY35 keyboard, or create a range of exotic split keyboard effects. The Multi mode is also ideal if you want to control the SY35 from an external MIDI sequencer, since 8 different voices can be assigned to 8 different MIDI channels.

Stereo Output
Since each element in any voice can be panned to any position in the stereo sound field, you can create true stereo voices that will add a new dimension to your sound.
