info KEYBOARD 61 velocity keys with aftertouch.
Main panel features a 16 X 2 display, 39 push buttons, 1 slider data and 2 wheels for modulation and pitchbending.


Rear panel terminal connectors:
- Midi interface
- breath controller input
- damp footswitch
- expression pedal input
- click out (metronome for sequencer)
- master audio outs
- headphones out
- 2 card slots for PCM waves and datas (see expansion)




edit
TECH CPU H8/523 unit manages 16 voices polyphony based on 16-bits AW2 Advanced Wave Memory 2 synthesis (IC YM7119 also filter) the SY55 DAC is a Burr-Brown PCM56P.
A patch main architecture is composed by 1, 2 or 4 PCM samples or ELEMENTS read out from internal ROM wavetable. Each PCM ELEMENT can be individually edited with various parameters:

sy55 architecture - volume mix
- pitch tuning
- effect amount
- keyboard zone
- special drum kit mode assigns 61 PCM in a single patch.




edit
WAVETABLE internal 2 MB ROM contains 74 PCM waveforms sampled at 32 / 48 kHz organized 3 categories: acoustic, digital and drums.

wavetable - 50 PCM acoustics samples e.g piano, organs... demo piano
- 8 PCM basic digital waves e.g sawtooth, square demo square
- 16 PCM various acoustic drums and percussions


FULL INTERNAL PCM LIST



edit EXPANSION a collection of set of DATA / DATA +PCM cards were available.
AI2 PCM cards are compatible between different Yamaha machines, so you can use SY-99 cards , TG77 RY30 on any 55 series. Note: This list is not complete.

edit PERFORMANCE
multitimbric section manages 16 parts each with assigned

tech

- reserved polyphony
- pitch tuning
- stereo pan position
-volume
- effect level

TIP: the global pitch amount can be assigned to aftertouch or randomized for each note.




edit
FILTER system is also based on a custom IC YM7119 featuring 2 digital resonant filters in cascade, each with a -12dB slope:
TIP: Cutoff can be controller by LFO or dedicated EG, but not both at the same time.

filter 55 - Filter 1 mode is both lowpass and highpass
- Filter 2 mode is only lowpass

edit LFO single delayed digital modulator (shapes: saw up, saw down, triangle, sinewave, square, triangle and sample& hold) for each ELEMENT and 3 destinations:

filter 55 - AMOD: LFO to amplitude
- PMOD: LFO to pitch
- CUTOFFMOD : LFO to filter cutoff

edit ENVELOPE 3 EG families per element:
- AEG amplitude : 4 segments + 5 levels and octave scaling setting.
- PEG pitch: 4 segments + 5 levels and octave scaling setting.
- CEG1 filter: 6 segments + 5 levels and octave scaling with special breakpoints
- CEG2 filter: 6 segments + 5 levels and octave scaling with special breakpoints





edit SEQUENCER
manages up to 8 tracks, recording mode in either step mode or real-time with a 1/48 resolution max. The time signature can be user defines in quite all manners (including 1/4, 4/4, 1/8/, 8/8,1/16, 16/16) in addition it is possible to used dotted, triples and ties.

sequencer

Some extra sequencer functions: event filter, track mixdown, insert, copy, delete and note gate time. Internal tempo rate range from 30 to 260 BMP.
SYNC: sequencer can be slaved to external Midi clock.

yanaha sy77 SY-77 (1989) workstation. RCM synthesis (PCM+FM). Module version is TG-77
yamaha sy99 SY-99 (1991) flagship of the Sy series with FM + RCM convolution and samples import.
