"This is a Dave Smith Mono Evolver synthesizer in very good used condition with only minor wear.Please note that this has the original encoders.Several of them can randomly be a bit jumpy and need to be turned a little slower.Cleaning the pots always helps with this.Overall,it works great and sounds fantastic.A wild and wooly piece of gear."

Sqsl Mills // A Quirky ‘Dilla Time’ Midi Sequencer for Mac and iPad by sqsl / Michal Macura
video upload by Gavinski’s Tutorials
"My review and walkthrough of Sqsl Mills. Mills is another quirky midi sequencer from Michal Macura / sqsl / seqsual for M1 Mac and iPad. If you like weird minimalist phasing loops in the vein of Steve Reich, or Dilla-style grooves with unique swing, you might dig this. This is a standalone app, not a plugin, but you can send the midi to control plugins, hardware synths, electric pianos etc.

video upload by Nitecaller.
"I got carried away again overdriving the filter but it's created some deep Cortini vibes. Left channel is running through an old Behringer phaser but the right channel is dry which together created an incredible stereo effect. Audio si

This Little Box Changed Synths Forever | Tom Oberheim’s SEM Story
video upload by Anthony Marinelli Music
See the full interview here.
"How did the legendary Oberheim SEM (Synthesizer Expander Module) come to life? In this video, Tom Oberheim himself tells the story of how necessity became the mother of invention.
After creating the world’s first digital sequencer, Tom needed a dedicated synthesizer voice to play back the note information generated by the sequencer. His solution was the SEM — a compact, self-contained synth voice that could be sequenced while leaving a musician’s main synthesizer free to perform alongside it. This groundbreaking idea gave players entirely new creative possibilities and laid the foundation for some of the most influential instruments in music history. Join me, along with Rob Rosen (Rosen Sound) and Marcus Ryle (Alesis, Line 6), as we hear directly from Tom about the innovation that started it all.
👉 Discover how the SEM was born and why it changed the future of synthesis."

The Haunted Arcade of the DecadeBridge Triad (Drones, Noises, Glitches and Rhythms)
video upload by Oscillator Sink
"The DecadeBridge Triad is a unique little Synth module that generates drones, rhythms, noises and glitches - it sounds, to me at least, like a haunted arcade in the 80s - malfunctioning machines, wailing, whirring and bleeping. It's based on a trio of analog oscillators arranged in a fairly unique, raw and unpredictable arrangement. It works great as part of a drone or noise setup, makes for excellent sample fodder, and thanks to the neat "reset" input it can play along with drum machines and sequencers (especially paired with a little low-pass gate).
