Analog oscillators hit different: exploring the SED-CSM and QSQ

video upload by SynthDad

"I dive deep into the raw sounds and harmonic richness of the SED-CSM, a complete analog synth voice from Rides in the Storm. With its dual oscillators, sub-octave generator, ring modulator, and a dedicated noise source, this module provides a massive foundation for everything from earth-shaking bass to evolving drones.
SED-CSM has two LFOs which can go into audio-rate, reaching up to 6.6 kHz and a VCF equipped with a dedicated overdrive switch. The SED-CSM offers endless possibilities for aggressive textures and squelchy, acid-inspired leads.
Complementing this is the QSQ; an 8-channel performance sequencer and MIDI-to-CV interface that serves as the brain of the operation. I show how the QSQ’s 16 analog-style rotary encoders allow for intuitive, hands-on melodic creation. Leveraging features like Euclidean rhythms, per-step probability, and integrated LFO/envelope generation, the QSQ compliments SED-CSM’s raw oscillators.
