"Some 70's-inspired tweaking with the GEMINI 2412, SAMPLE & Hold, and a Sequencer.
Video & Performance by ‪@DreamsOfWires‬
The Gemini is based on the classic Oberheim SEM filter, but with expansive flexibility, including a unifying CV and Audio mixer section between the two multi-mode VCFs. There is a shared output for both filters in 'Dual' mode as used here, but also separate shared outputs for each VCF, through which filter mode can be selected, and individual outputs for LP, BP and HP filters on each.
Also, a jumper on the back alters the behaviour of both filters individually - standard SEM resonance range, or extended high resonance setting that'll allow the filter to self-oscillate. 1V/Oct inputs are present for both filters, so each can even be used as a simple sine wave oscillator over a few octaves.
