MiniMod & Ribbon Controller - AJH Synth Eurorack Ambient with Gemini 2412 'SEM' style Dual Filter

video upload by AJH Synth Official

"A 2-voice ambient performance using the Doepfer ribbon controller with the AJH Synth MiniMod eurorack modular system, here incorporating the Gemini 2412 'SEM-based' dual multimode filter/VCF. Simple 2 note/2 VCO chords are shifted in pitch with the Ribbon, and pressure sensitivity used to control the Gemini's overall frequency, and the level of pitch vibrato from the Dual LFO module, which has a built-in VCA. A third VCO via the Transistor Ladder Filter creates a single oscillator drone sound (a square wave with pulse width modulation/PWM), whilst the Dual LFO also modulates the frequency of this VCF, and both VCF's on the Gemini in position to each other. The Gemini is used as a stereo filter, with both going of it's VCF's going to separate VCA's and audio channels to creates a stereo panning effect.
The Gemini can be used as 2 filters in series, or in stereo with a single audio input signal, but here both filters are processing a different VCO via their individual inputs, whilst the global Dual Frequency CV function of the module's central mix bus section allows them both to be controlled in unison, in addition to, or instead of their own individual CV control. This offers a huge amount of flexibility.
A suitably large reverb is added in post to add a film/movie soundtrack quality to the sound.

Check out the AJH Synth playlists for module 'User Guides', and 'Patch of The Week' videos, which will be either performances or 'how to' guides, detailing functions/methods, and a range of sounds, some familiar, some less so, containing a patch sheet at the end to show you how to construct it for yourself.
