MIDI quite basic but full MIDI exclusives is implemented with full support of edit and data dump. stereo Tones with reverb to upper or lower tone.

LFO 3 delayed modulators (shapes: saw, triangle, random and square) and 3 destinations:Īll partials have their own EG for both amplitude + filter, for a total of 4 TVF EGs and 4 TVA EGs.ĮFFECTS 2 dedicaed chips (87136+87137) handles 32 reverbs echoes + 7 chorus modulations + 1 simple serial -12 dB EQ with HIGH settings boost (250 Hz) or a LOW boost (63 Hz) + Q-emphasis.Įffect can be balanced with dry / wet parameter to different tones in 3 modes: TECH filter has a restriction: TVF does not act on a PCM element, later possible on V-synth D50 emulation. PATCH can be played also with a legato with variable portamento time.įILTER structure is based on the TVF -time variant filter- which is a digital 4-poles resonant lowpass filter. PERFORMANCE parameter CHASE is a delay mode between the tones with 3 directions modes: In total there are 101 sound waves available:Ģ digitally generated sawtooth and square waveĪLGORITHMS the WG combines partial synthesis elements with a digital ring modulator in 7 possible pathways or algorithms: (p= pcm sample / s= digitally generated wave)

WAVE GENERATOR is a 128 kb ROM (at IC29-30) PCM wavetable + a digital waveform generator. WG (voice) + TVF (filter) + TVA (amplitude) Minimal part is the PARTIAL composed by 2 UPPER tones + 2 LOWER tones then 4 combined tones make a PATCH TONE has value for relation between both partials and each partial is like an oscillator with various synthesis chain elements. 2 Digitally generated basic waveforms sawtooth & square wave, a kind of primitive VA LA synthesis WG Wave Generator is a mix of 2 syntheses: TECH main core is a 8-bits CPU CMOS UPD78312 manages 16 voices polyphony - relative DAC is a Burr-Brown model HP54HP. 2 pedalswitch inputs assignable to patch change / chase / portamento On the left side there is a joysticklever for modulation.Ģ pedal expression assignable to tone mix/aftertouch/ modulation Main panel features a 2 x 40 lines display, 54 buttons, a data entry slider and a data card slot. KEYBOARD 61 velocity keys with aftertouch. L.A synthesis: hybrid sampled PCM short waveforms and generated synthesis. The D50 is one of the greatest all-time sales along with Korg M1 and Yamaha DX7.
