VOICE 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.
PATCH 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:
- volume mix
- pitch tuning
- effect amount
- keyboard zone
- special drum kit mode assigns 61 PCM in a single patch.
WAVETABLE internal 2 MB ROM contains 74 PCM ( PCM LIST) waveforms sampled at 32 / 48 kHz organized 3 categories: acoustic, digital and drums:
- 50 PCM acoustics samples e.g organs
- 8 PCM basic digital waves e.g sawtooth
- 16 PCM various acoustic drums and percussions .
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.

Based on a custom IC YM7119 featuring 2 digital resonant filters in cascade, each with a -12dB slope:
- Filter 1 mode is both lowpass and highpass
- Filter 2 mode is only lowpass
TIP: Cutoff can be controller by LFO or dedicated EG, but not both at the same time.
single delayed digital modulator (shapes: saw up, saw down, triangle, sinewave, square, triangle and sample& hold) for each ELEMENT and 3 destinations:
- AMOD: LFO to amplitude
- PMOD: LFO to pitch
- CUTOFFMOD : LFO to filter cutoff.
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.
SEQUENCER 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 (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.
SYNC sequencer can be slaved to external Midi clock or internal tempo from 30 to 260 BMP.
EFFECT SP YM 3413 handles 34 fully editable effects, including reverb (x8), delay, stereo panning delay, gate and digital distortion. Full effect LIST
Keyboard manages up to 16 parts each with assigned
reserved polyphony, pitch tuning, stereo pan position, volume
and effect level
TIP: the global pitch amount can be assigned to aftertouch or randomized for each note..
The Special CONTROLLER section (in utility mode) allows to assign some parameters like filter cutoff, volume, modulations to any control changes on the Midi list.
Full sysex implementation is supported.
MEMORY:
- 64 ROM patches (PRESET LIST) + 64 RAM
- 16 ROM + 16 RAM performances
- 999 sequencer measures
- 8000 sequencer notes.
RAM is doubled using memory cards model MCD-32 or MCD-64.
Battery replacement: a cr2032 3V soldered to mainboard
- polyphony
- some dated internal waves
- sweeping filter
- cheap
