Basilisk - Analog-Hybrid Generative Bassline Synthesizer Dual Digital Oscillators, Saw & Square/Pulse Analog MS20-style Filter With Overdrive Generative Sequencer with LFO and Parameter Lock Modulation External Audio Input Basilisk is a bass-line exploration synthesizer, with dual digital oscillators driving into an aggressive MS20-style analog filter all powered by a built-in generative sequencer. Whether you need thumping bass-lines, melodic leads, or percussive tribal beats, the Basilisk is ready to lead you down the rabbit hole from the moment you power it on. The dual oscillators include saw and square/pulse, with manual & LFO control over PWM, detune, pitch envelope & glide. The analog filter has a fat saturated drive stage with resonance that can go from subtle to squelching & screaming, and includes an external audio input to process instruments from your desktop or Eurorack modular through the filter. All of this can be modulated by the attack/decay exponential envelope, multi-waveform multi-destination LFO and Elektron-style parameter-locks. The Basilisk’s brain is a 1-16-step generative sequencer borrowed from the Freaq FM, with multiple algorithms. Explore deep space, underground caverns and deep jungle or 1980s suburbia!
