The basic synth is called the DS202 , with two expansion – the DS310 digital synthesizer and DS320 sequencer.
Once everything mounted on the synth, the size is quite impressive.
A sturdy and well-conceived gear, for a total 16 to 17 lbs. No MIDI out.
Basic sounds (namely PIANO ORGAN HARPSICHORD FLUTE STRINGS ELECTRIC PIANO JAZZ ORGAN VIBRAPHONE CLARINET BRASS) are crystal-clear.
They can be edited using the LPF filter, Envelope Selectors 1-4, 4 sounds that can be saved and two chorus effects.
The delay (off, short or long) and sustain attack and release can be set using the ‘Time” sliders which happen to be very precise (values include 0, 0.01, 0.02 , 1, 2, 3, 5 or 10 seconds).
Every parameter can be set using the LCD screen, the 4 envelopes available can be visualized as well as the spectrum settings (over 16 harmonics).
Effectwise, there’s a Chorus 1 that offers a slow cycle around 0.7 Hz, while Chorus 2 is around 1.7 Hz.,and a Vibrato effect can be added. The keyboard can be transposed.
Many variations are available, so as a consequence the user bank is bit short.
The key’s touch is pleasant, it’s easy to use but the sequencer and digital synth still require reading the manual.
As for the rhythms, the drum machine provides a Roland CR78-ish sound. The “one-finger” bass auto-backing is very cool.
I haven’t had an opportunity yet to use it during one of my sets, so let’s wait and see…
This synth is so rare that it’s a real collectible, with these options it cost around 1000 MARKS back in the days but I got it for 200€ + 75€ per module, and that’s a purchase I clearly don’t regret.
