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).

Life's Window | Prophet 10 soundscape
video upload by MIDERA
"It was my Dad's birthday today. He didn't make it to this birthday, or the last 14 birthday's either. Time just goes on and takes everything away from us. But I wanted to write something on his Birthday. I miss him. I miss my mom too. I miss them both.
Meanwhile, I'm just barely hanging on. My wife still hasn't found a job and I sometimes think she won't get one before I lose mine due to all the awesome stuff going on in the federal government. We've been worried about what will happen when we're both without jobs. I couldn't get a job if I tried (and I have). I guess no one wants someone who has a really niche background. It's just not a great place to be.
Life goes on anyway.

This might be the best Novation Circuit track yet!
video upload by Guinan
"It started out as a bit of a challenge but in the end turned out better than I hoped.
Everything you hear was programmed on the Tracks synth (and if required, sampled into the Rhythm). Only the drums and vocals are samples from elsewhere and the whole thing is played back on the two machines and recorded (without any extra synths or effects)."
ORIGAMI oscillator, wavefold external sounds
video upload by LARIX ELEKTRO
"As all my modules, each function is accessible independently.
Here, we will use the folding circuitry and replace the internal VCO by some other sources:
Drum loop
The UNDULA OSCILLATOR (with its own folder)
and some FM with the Quad Operators from Humble Audio
Note that this is a prototype, the final version should be better..."
