not yet another lfo/vco pair, the model 52 vampire is a dense timbral pitch source that will re-animate even the most cadaverous patch.
similar to a complex oscillator, vco1 is pre-routed through panel switching and jack 'normalling' to synchronize and frequency modulate vco2's linear or exponential inputs.
like a dual oscillator, two full range oscillators provide a fat audio output with six possible waveforms each individually and externally available for synchronization and external modulation.
then things start to get out of hand ...
the usual voltage controlled morph effect is re-imagined to cross-fade vco2's pwm waveform to the output of a voltage controlled wave-scanner providing dynamism that is truly 'un-dead'.
vco1 provides either a ramp or triangle waveform to window (envelope) either vco2's sin2 waveform or jacked in external audio to range from near articulation to buzzy, chopped, alias-like revenant
audio.
based upon triangle cores, vampire oscillators provides clean sawtooth waveforms and a hard-sync of consistent direction for enveloping waveforms. a panel switch allow frequency coupling/un-coupling from
1v/octave input.
vco 1
frequency range:
.018hz to 16khz mode-less
input modulation:
exponential with uni-polar attenuator
synchronization:
clk out: uni-polar 0-5 v
sync input: any input waveform sets oscillator waveform to slew positive.
external output:
manual rotary switch selects any of 6 vco 1 output waveforms to emit from lfoselout for external use.
internal routing:
modulation: any of 6 vco 1 waveforms switchable to vco 2 linear or expo modulation inputs.
windowing: switch selected sawtooth or triangle waveform amplitude modulates either vco 2 sin2 waveform or external audio input to extaudio jack.
vco2
frequency range:
.036hz to 32khz.
external modulation:
linear and exponential with bi-polar attenuators.
external output:
manual: two independent rotary switches select any of 6 oscillator waveforms to emit from vcosel1/2 outputs
voltage controlled: panel or external voltage cross-fades vco2 pwm to a voltage controlled selected vco2 waveform.
windowed: vco1 saw or tri wave amplitude modulates vco2 sin2 or external audio input.
vco1 waveforms
for external connection, vco1's output waveform is selected by a manual rotary panel switch and output on the lfoselout jack. vco1's clkout is simultaneously available.
appropriate for an lfo, ramp and sawtooth (which sound identical at audio frequencies) provide significant difference when used to enveloping.
the fifth vco1 waveform is actually the windowed waveform output (triangle mod shown). this allows vco2 to self-modulate for additional waveform alteration.
vco2 waveforms
for external connection vco2 provides two channels of output waveforms selected by a manual rotary panel switch and output throught the vco1sel and vco2sel jacks.
vco2's fifth waveform is the windowed waveform output (ramp modulation shown). if neither ramp or triangle is selected this output is the sin2 output or input external audio.
the functionality is dense, the capability is large, and the sound is positively un-dead.
the model 52 vampire inters this versatility in a 21hp module and connects to power with 10 dil eurorack connection.
