KORG Mono/Poly

via this auction

"Vintage 4 voice analog synthesizer... Fantastic synth for a so many things and the ability to twist and change the sound in so many different ways. Layer the 4 voices in mono (unison) mode , detune and alter the waveforms of each one for thick and lush leads.. then start modulating the sound in many different ways. Appegiator , poly mode ,chord memory ..korg really piled in the options."

Yamaha DX-7IID

via this auction

"# The 'new generation' of DX synthesizers (Mark II). This model has everything the DX7s added plus:
# 2-channel tone generator, which allows bi-timbral effects including stereo, splits, and layers.
# each of the two tone generators can be controlled independently via MIDI on separate channels, making the DX7IID do the work of two DX7s keyboards
# larger LCD display and an extra LED voice display for the second channel's voice number"

Yamaha DX-7S

"Classic synth sound of the 80's .The original FM synthesizer. DX-7S was the updated version of the original dx7 which included better sound output 16-bit (as opposed to the original 12-bit D/A) , a new case design (lighter but just as hard wearing) and the addition of unison mode."
