"All original Korg Trident Ensemble analog 8 voice polysynth 1980-81 MIJ still. NO MIDI on this synth! This is an awesome vintage analog synth,16 memory patches only though. The Trident also had a very excellent onboard/built-in Flanger effect, when turned on and blended/mixed with the other sections made some weird and wonderful polysynth sounds for sure! These had really nice analog string & brass sounds, especially the Strings section as this was really a String Polysynth first and one of the best ones ever at that back in the day. Also this was Korg's professional flagship analog polysynth around 1980-82,and it was way better, and way more expensive than the Korg Poly 6 or the Roland Juno 6/60, and Korg Poly 61/Poly61M, which came on the market more or less at the same time, early 80's. All of the other ones mentionrd had fake cheaper wood particle board ends,which always broke way too easy, unlike the real solid hardwood ends on the Trident. The Korg Poly61M came a little later as it had early basic MIDI. The Trident had 3 separate Ensemble sections--- really excellent Strings, decent Brass, and a decent Polysynth, which could be all blended/mixed together--- all 61 keys for a thick sweet analog polyphonic/paraphonic polysynth, but only any two sections at a time in split-key mode. Each section had its own unique separate VCOs and ADSR enevelopes/VCO filters, and programabilties. There are no issues that I am aware, of all oscillators work proper, no dead keys or voices, no broken knobs or other controls,or sliders anywhere, and they all work 100 %, all leds light up, as well as Korg's unique 4 way pitch bender, which was very unique and is perfect and unbroken as, these sometimes are on the Trident, and the VCA is very loud on this synth!"
