This is a self-contained semi-modular synthesizer with a 37-note (F-F) keyboard. It features an ADSR, LFO, Portamento, a VCO (with pulse width modulation and a tuning knob marked in Hz from 10Hz to 10kHz), white or pink noise, an audio mixer (with sliders for VCO, Noise, and External Input), a high-pass filter, a low-pass VCF, and a VCA with input for LFO. There are also buttons for auto-glide and manual-glide and an A-440Hz tuning oscillator. All of this in 21 sliders, five knobs, 14 mini-jack sockets, seven switches, and three 1/4" jacks (for headphone and high and low outputs).
This is essentially a keyboardless Synthesizer 101, with a few exceptions. It was designed to sit upright, behind the 101. Instead of glide controls, the 102 has a sample-and-hold module with variable lag time, and instead of noise, the 102 has a ring modulator. The 102 also features weak and strong sync inputs and a mix cascade jack socket instead of the tuning oscillator
just to update the listing. both still have the original 2 pin plugs on them, both are 220-250v, and both do light up when plugged in.
will add some more photos tonight.
heres another update to answer some questions people have been asking,
all the sliders move ok
all the knobs turn ok
i cant see any damage to the paint.
i tried it out with a pair of headphones and can hear noises, the noise changed with the controlls, every key i pressed made a different sound.
if you need a photo or close up of anything specific i will need your email address and i will do my best to send you some photos
sorry no overseas postage
cleaned synth today as it was dusty and dirty, has come up very nice with all the lettering nice and clear., the keys now look much better.
