For this patch we are using the Gemini in DUAL Mode, so the Dual switch is down and the Invert switch is up (off).
In this example we are looking at mixing and filtering two different audio sources to a single output. The audio inputs can be
anything - VCO’s, full synth voices, noise or external audio - however they both need to be at Eurorack Modular levels - i.e. 10V
p/p.
The two audio inputs are patched to inputs IN 1 and In 2 respectively, and here we are using the central Mixing bus to cross
fade and combine the two signals into a single audio output, which is fed to the D-OUT jack.
We can cross fade from VCF 1 to VCF 2 either manually with the AUDIO MIX control (when no cable is patched to the MIX CV
input), or we can use a CV voltage of 0 to +5V, patched to the MIX CV jack, to pan between the two filters. The AUDIO MIX
control acts as an attenuator for this control voltage, so simply set it to a position that gives the desired panning range.
We have also shown a dual envelope generator to control the cutoff of each filter individually, obviously this is optional and
and is shown as one of many modulation possibilities.
Please note that even with the filter cutoff’s set full open and the resonance set to zero there is still some colouration and
distortion to the resulting sound due to the filter circuitry, and in many cases this is desirable, don’t expect this to be a super
low distortion Pro-Audio mixing solution... It is shown as a combined mixing and filtering modular patch which will add some
character too!
Note: The numbers used to illustrate control knob positions do not relate to the markings on the module itself, but are simply a scale from zero to 10 with 5
being the control centre position. For attenuverters the control positions are -10 to +10, with zero being centre position for the control knob.
