AJHSynth-Gemini 2412 demo/Minimod oscillators/filters and more!!!

"Hi Guys.
This time I have an extensive demo showing the filter Gemini 2412 (no talking) from AJHSynth !
in the first part, up to 1:50, you have two Minimod oscillators (Vintage Transistor Core VCO) - they are first with a lower input level, later with a high level that adds some grain in the Discrete Cascade VCA and, of course, a typical LP, BP, HP filter, plus of course adding resonance. I think wonderfully shows how this filter behaves on the oscillator.
from 1:50 to 4:15 is used Dual mode for sequences with the addition of Reverb Black Hole DSP from Erica Synths.
in dual I wanted to show a lot of filter settings, that's why it takes quite a long time, and as it alternately filters itself with the use of LFO, there is a separate output for Dual D-Out. last part is a sequence with filtering also dual but without reverb.
The Gemini 2412 filter is based on the iconic SEM so this character really can bite sounds.
More specifically, the Gemini 2412 is Two completely independent Vintage SEM filters, with a central mixing bus for frequency and frequency control voltages that allow the connection of two VCFs in serial and parallel modes, and VCF1 can be inverted against VCF2. So two VCFs can be combined to act like a SEM 24dB filter, vocal formation filter and much more!
Each of the two filters is based on a SEM vintage filter, with FET transistors, and has a Low Pass, Band Pass and High Pass outputs, and a useful Vary output that can be faded from LP to Notch on HP. All outputs can be used simultaneously.
Added some exciting additional features not available in the original SEM filter, including CV resonance contolance, VCF core override and full self-oscillation!
Each VCF1 and VCF2 has a four-way switch for selecting LP, BP, HP or VARY for the mixing bus, it is also available as an additional individual output."
