The Bateleur VCO is an analog oscillator offering Thru-Zero FM and a massive sound. The module includes a separate four-pole low pass filter to also offer an additional sine wave in self-oscillating mode, all in all being perfect for sweetest FM sounds and much more. Well done and not that small and tiny.
Discrete, temperature stable and 100% analog oscillator with a vntage sound so rich and direct that it almost jumps in your face!
Waveform-wise we find the four classics: sine, triangle, sawtooth and pulse. In addition there's a subsocillator output. Of course the pulse width can be modulated, both manually and via the scalable PWM CV input.
The VCO's coarse frequency range is set with the range rotary switch whose action is soft yet very precise. The fine frequency is set +/-7 semitones with the FINE control.
Glide does what you expect it to do - it adds a portamento.
The white highlighted area is the frequency modulation department which of course is a must. It can be selected between normal and Thru-Zero FM. Especiall the latter sounds very rich and beautiful! (nota bene: the FM attenuator turns into a polarizer when Thru-Zero is selected.)
The filter's input has been placed directly below the waveform outputs for easy patching the VCO into the -24dB/octave steep low pass filter by using a short patch cord. Soundwise there is absolutely nothing to complain about - this is a fat classic LPF with a lush sound!
It's not a must to use the filter together with the VCO as there are individual inputs and outputs - although you should be aware that the 1V/octave input is always normalized to the cutoff frequency.
Idiosyncratic is the fact that the VCF has no resonance control but a switch only which either chooses 0% resonance or, at ◉ setting, the full self-oscillation. In latter position the filter turns into a great sinewave generator which is perfect as Thru-Zero modulator - and suddenly the steady 1V/octave-to-cutoff normalization makes perfect sense in order to keep frequency ration constant! Brilliant thinking!
The Mk2 version has several improvements:
- Frequency range swithc has six positions, including a LFO mode with improved fine tuning (+/-2 octaves).
- Sync mode as thrid FM setting.
- additional filter mode decoupling the self-oscillation from the 1V/octave input.
- The filter is stable over a range of seven octaves and closes entirely.
- oscillator core is compensated over seven octaves and offers a new trimming function.
- VCA noise floor and bleedthru have been minimized.
- 10-pin header for connecting to the Birdsnest for polyphonic and internal activation.
