1 VCO with 1 LFO for pitch modulation, 1 Noise Generator, 1 VCF with 1 LFO for cutoff modulation, 1 VCA, 1 ADSR for VCF and VCA.
Good features: + LFO's are superior because their frequency ranges up to 5 kHz. + VCF has a keyboard tracking function and has an external audio input. + It has a simple build in MIDI to CV or CV to MIDI Interface (switchable) and the Cutoff frequency can be controlled via MIDI.
Bad things: - It can only be switched between the VCO, Noise Generator and the external audio input. - No auto tune function - Complicated handling of the midi functionality with a learn switch (e.g. if you want to change the midi channel)
The last thing is not that important because you usually adjust this only one time.
It's not produced anymore.
