Give II is a 10 HP Classic Analog VCO with additional Frequency Divider and Waveform mixing options

Give II is a 10 HP Classic Analog VCO with additional Frequency Divider and Waveform mixing options.

It is not a substitution for GIVE I, but rather another version as it is based on the same core circuit. Actually both versions complement each other very well building a powerful complex oscillator.

The VCO provides five outputs, the last four of them can be mixed with an integrated mixer:


Patching a voltage/audio source into FM you can frequency modulate the oscillator. Incoming voltages can be attenuated with FM CV. In the middle of the module you will find the PWM potentiometer. Here you may change the pulse width of the pulse wave. The width may also be controlled via external voltage with the PWM jack and the PWM CV attenuator.

Just like all other classic analog VCOs GIVE II also tracks one volt per octave with the help of the 1V/OCT input jack. Each wave can also be hardsynced by an external wave patched to the SYNC jack.

In addition to the classic VCO functions GIVE II also provides an integrated frequency divider. The MIX output jack will not only supply the waveforms SAW, TRIANGLE and NOISE, but also provides up to 3 sub octaves derivated from the PULSE waveform. The volume of each suboctave may be adjusted with the potentiometer SUB 1-3. ORIG will adjust the volume of the original PULSE signal. Using the switch ORIG SQU you can flip the SQUARE waveform.
