But the new frequency shifter will be equipped with a squelch circuit (envelope follower and VCA) that suppresses the oscillator feedthrough when no signal is present. And we have also finished the development of the for a long time announced thru-zero-quadrature VCO and will present the module at NAMM in January. The module has a pure sine/cosine core and the waveforms are not derived from other signals (like sawtooth or triangle). Consequently the sine/cosine have a high quality with no overtones. It's not yet sure if it will be released as a single module (e.g. for the frequency shifter) or a dual thru-zero-quadrature VCO with voltage controlled FM indices (i.e. for each FM direction 1->2 and 2->1, also for cross modulation). But we will probably prefer the single version as not every user looks for a dual module. And the dual version can be simply realized by two of the modules and a dual VCA (e.g. A-132-3).
