SY77

Yamaha SY77

Released: 1989

MSRP: Y315,000 ($2995US)

Synopsis:

RCM hybrid (AFM and AWM2) mixing FM and samples, allowing samples to be used as operators. AFM is 6 operator, 45 algorithm with 16 waveforms (3 feedback loops). AWM can modulate an FM operator. Up to 4 elements create a voice, but if multiple AFM or AWM elements are used, polyphony is affected. Architecture Class: FM-Rompler.

Ebay Description:

The Yamaha SY77 is a pressure and velocity sensitive 61 key (16+16 voice multitimbral) hybrid (FM and sample based) synthesizer, featuring up to 4 elements, (7 stage) pan envelope, microtuning (64 presets), 44 DSP effects (4 processors), card (program and sample) and MIDI interfaces, disk drive, 16 track sequencer, dual stereo outputs, and 192 presets (64 editable). Each element has AWM2 (112 samples) or FM (6 operator, 45 algorithm) with dedicated (7 stage) envelopes, a 5 stage pitch envelope, an LFO (saw up/down, square, triangle, random waveforms), 12dB digital low|high pass and low pass filters with dedicated (7 stage) envelopes.
