Pics of the inside below.
This is the Mark III - final revision. Includes box, adapters, manuals, etc. Purchased directly from Twisted Electrons in May 2024. This is their last batch of TherapSIDs. They do not come with MOS chips but I'm including two modern simulated SID chips. They still sound great!"

Introducing Sapphire Chaops - expander module for Frolic, Glee, and Lark
VCV Rack - Sapphire - "Ice Station Oberon 11" - custom virtual synth
video upload by Don Cross
"Tonight I made a complex synth voice from several voices, but all tuned to the same V/OCT signal. Then I decided to play that synth voice using a virtual keyboard (Impromptu Twelve-Key). Usually I do generative stuff, but it was fun to make something more in the spirit of a custom synth, and then to perform that synth.

Introducing Sapphire Chaops - expander module for Frolic, Glee, and Lark
video upload by Don Cross
"Chaops is a new 'chaos operators' expander module in the Sapphire plugin for VCV Rack: https://library.vcvrack.com/CosineKit... Here I show how to use Chaops to store/recall the state of Frolic, Glee, or Lark. Chaops also allows you to morph the 3D vector output on a spectrum between position and velocity, which provides a new range of 3D chaotic curves. Finally, Chaops can freeze/thaw the movement of the attached chaos module. All of this functionality can be operated manually or by input voltages."

** VINTAGE ORIGINAL** // KORG MS-20 // DUSTING OFF // OVERTONE SINIGING // PURE SOUND // no talking
video upload by LESINDES
"VINTAGE original KORG MS-20 still an unbeatable sound source. Despite some heavy crackling. How versatile it is you can hear. Dusting it off is really worth it. Here is a DRONE with some forgotten OVERTONE SINGING."

Analog audio FX: Pipeline Distortion, build
video upload by RS-Elc
"Demonstrating a simple circuit that provides flexible and dynamic signal distortion as a sound effect for synthesizers and gitars. Basics explained in my movie : Pipeline distortion, basics. Here the build version is shown with sound examples. Note that for the sound examples the input is just a basic sinewave, all harmonics and modulation come from the distortion effect. (no other effects are used).
