After all the A-110-2 would not be a new oscillator but a simplified A-110
to keep the price as low as possible (i.e. an A-110 without waveform
converters for triangle and sine, and without rotary switch for octave
range). We could offer such a VCO in the Euro 100 range. But in the meantime
I'm not sure if an A-110-2 really would make sense because we are about to
try another VCO design similar to the announced A-143-4 but with a sawtooth
core (in contrast to the triangle core of the A-143-4) and some additional
features like linear FM and Sync. We could probable offer a quad VCO based
on this new design for about Euro 200 (i.e. Euro 50 per VCO) - provided that
everything works as it should. The tracking of the existing second
prototype of the A-143-4 is good over ~ 6-7 octaves from 32Hz to ~ 4kHz. We
still have to measure the long-term temperature stability and find out if
latching effects occur if the frequencies are very close to each other. I'll
keep you informed.
By the way in the LFO mode weird waveforms can be generated by the A-143-4
when the VCLFOs modulate each other. Especially multiple cross-modulations
(i.e. more than two oscillators modulate each other with feedbacks between
the oscillators) are crazy.
