"One of the rarest and hardest to find 80’s Yamaha synths
Here is the flagship of early 80’s Yamaha synthesizers. The SK50D is a multi-instrument analog synthesizer with built in effects. It features dozens of sliders, knobs, switches, and lights allowing the user to create an infinite amount of unique sounds. Its got a fully tweakable monosynth and fully tweaklable polysynth.
The monosynth features 1 VCO and the polysynth feature 2 VCO’s. It also features full ADSR as well as a Low Pass Filter. Built in effects include Glide, Portemento,Vibrato, Tremelo and Ensemble. It features independent jacks to each instrument which allows the user to customize and project each individual instrument to the users preference.
122 key 2 tier synthesizer/combo organ with built in Monosynth, Polysynth, Bass, Strings, and Organ each with their own individual volume control slider, so you can use the slider bars as a mixer to set the individual volume for each section.
All sections have their own separate audio outs (though a single Mix out is also available). A great thing for live performances is the split keyboard mode. With this you can have, for example, a very nice, punchy bass sound from the synth section and a lead sound coming from the organ or solo sections.
Dual keyboard multi synth instrument with both preset and programmable sounds.
It has a 9 drawbar organ, monophonic bass synth; a woofer killer bass with sine 3 oscillators.
It has a monophonic solo synth that can be layered with the bass synth for even more power and it responds to aftertouch!
There is a fully programmable 7 note polyphonic analog synth with VC LPF and resonance and it has three presets, and a 7 note polyphonic analog string synth ( actually these are the same synths which can be layered without losing polyphony but the string synth is a preset player with three preset sounds. The three string presets are almost the same sounds playing one octave higher than each other).
The aftertouch can control filter, filter modulation and vibrato at the same time.
Organ plays on both manuals. Mono synth usually plays at upper keyboard (can also double bass synth at the bottom keyboard), poly synth, string synth and bass plays at the bottom keyboard only. The sounds that play on the same keyboard can be layered without losing polyphony. What a beast!
It has ensemble and tremolo effects with speed variation control seperately on both keyboards and detune effect for the poly synth.
Seperate audio outputs for each sound and an on board sound mixer .
It is a very rare instrument. Very playable with lovely key action and gigable in its own hardcase. Has no MIDI but has got CV and trigger IN/OUT. Also a leslie cabinet connector."
Each section has separate outputs, plus there's a mixed output, and a headphone output. There's even a direct Leslie tone cabinet connection that makes for a truly unbelievable combination (see the video links below)! [at the auction or see this post and this post]
