The AJH Synth GEMINI 2412 is a Dual Vintage State Variable Filter Eurorack Module.
In this Eurorack Module Video Review, we go over all the filter module features:
- Analogue filter types (LP, HP, BP, Variable Mode).
- Dual Parallel Mode
- Dual Serial Mode
- Inverting Phase
- Central Audio Mix Crossfader and Filter Offset ‘manual and CV controllable’ bus
- CV Control features
- 1V/Oct Self Oscillating Mode
- And more sounds and stuff … :)

I also use the AJH Synth Finaliser R-EQ for a bit of Reverb here and there. A full review of the Finaliser R-EQ will follow soon.

Towards the end of this Description, I have included links to some of my other reviews of AJH Synth MINI MOD and not MiniMod Eurorack Modules
