Synthesizing with Moog | Lesson 4: Resonance
video upload by Moog Music
Synthesizing with Moog
"In 1964 the modular synthesizer was born, and one of its signature components was the Voltage-Controlled Filter. While different oscillator shapes could create a bed of tone and harmonics, the Voltage-Controlled Filter allowed musicians to sculpt a distinct sound out of all those harmonics and even shape that sound over time. A key component in synthesizing existing sounds, the Voltage-Controlled Filter was also capable of creating sounds no one had ever heard before, giving birth to whole new genres of music and defining the sound of electronic music to this day."

Jam - Arturia Minibrute 2S and Eurorack w/ Scrapcode Modules
video upload by Scrapcode Modular
"A little jam making use of my new @ArturiaOfficial Minibrute 2S and Eurorack rig.
Kick and bass are being generated and sequenced by the 2S, while pad and bleeps are a mixture of @scrapcodemodular AXIOM, WONK and (prototype) QUORD, running through a Doepfer Quad-Filter and @Dreadbox-synths Psychosis.
All sounds created live and recorded directly from the rack - the only post-processing is a gentle limiter and level boost."
