About This Listing

The unit is professionally serviced (recapped, cleaned, tuned) , tested & is in ideal 100% working condition.

Cosmetically it has a lot of signs of use but synthesizer in full working condition

It is build like most of the string machines from this time. A high frequency top-oscillator is divided into 12 freqeuncies that make up the top octave. Each of the 12 notes is then divided down by 2:1 several times to create the different octave found on the keyboard and in the footages of the different registers. All this is done with square waves. These are then mixed, filtered or shaped to generate the the sound. Yws, this is just like an typical organ keyboard.

But then comes the very special sections that makes to sound different from a simple organ:
the multiple analog chorus unit.

Different presets for the modulation sections are available (4 for each section), and are selectable by pressing the eight corresponding switches on the left hand side of the front panel.
The presets for the percussion section are:
"direct":no chorus is applied to the signal
"slow": only the slow sinewave is used as CV for the chorus. Only the output of the first stage is used and mixed at a 1:1 rate with the "direct" signal(the schematics read "phase shift" for this preset, though it is in fact a chorus) "chor1": only the slow sinewave is used as CV for the chorus, though this time all of the three stages are used, and their outputs are mixed together a a 1:1:1 rate
"chor2": the CV waveform is the sum of the slow and fast sinewaves, all three stages are used and their outputs are mixed together at a 1:1:1 rate

The presets for the strings section are:
"direct": same as the direct of the percussion section
"fast": the CV waveform is built up of the fast sinewave and an attenuated version of the slow one. Only the output of the first stage is used and mixed at a 1:1 rate with the "direct" signal(the schematics read "vibrato" for this preset, though it is in fact a chorus) "chor1": same as the chor1 of the percussion section
"chor2": same as the chor2 of the percussion section
