Erica Synths - Fusion VCO Mixer (v1)

This module contains two three-channel tube mixers which have been designed specially for direct mixing of VCO waveforms. Because of the tube sound and it' saturation behaviour this module can be used as a fine waveshaper, which can sounds pretty brutal when 3 VCOs are mixed at high levels. Especially living waveforms with constantly changing harmonic content like PWM will be heavily processed by the tube.

As said earlier, each of the two mixers has three inputs and with a good reason they have adjustable level: the maximum gain of the mixer is 1.5 s oit is easy to overdrive the inputs. So if you like it rather clean, just turn down the level!
The inputs are fed directly to the tube and for that reason it is possible to mix almost all signals with all levels.
Besides a positive outupt there is also a phase inverted one.

A very interesting, almost waveshaper-like behaviour occurs when the input signal changes dynamically it's harmonic content, for instance a pulse modulated square or a waveform that is blended from sawtooth over triangle to ramp.
