How we have fallen
video upload by MIDERA
"Terrible things are happening outside. Poor helpless people are being dragged out of their homes. Families are torn apart. Men, women, and children are separated. Children come home from school to find that their parents have disappeared."

What is it about the Oberheim TEO-5?
video upload by Molten Music Technology
"We've had the TEO-5 analogue synthesizer on show at the last couple of Synth Picnic events and it's consistently the synth people like the most. Let's have a wander through it's gooey electrical circuits to see if we can work out why."

Recreating String Ensemble sound with Poly Synth
video upload by George B.
"Today I used my OBX8 to recreate the ARP string Ensemble sound. By breaking down how the String Ensemble worked internally, I used what I learned to simulate the ensemble effect. Also I have a three channel ensemble board from an 80's organ that I built into an effects box. So I could compare my settings. Hope you like it!
0:00 Chapter 1 Intro
1:29 Modulation
3:12 Settings
5:12 Double Mode
6:20 Demo - Check this out...playing the string sound over a sequence."

"The legend. The Xpander is absolutely one of the Top 10 synthesizers of all time. This machine is the sound of so many amazing records. Depeche Mode. Erasure. Nine Inch Nails. The Chemical Brothers. Orbital. The list goes on. It is also one of the most flexible synthesizers with patch memory ever made. It is truly modular with vast routing possibilities. And then there is the sound. Classic Oberheim attitude.
This machine is in very good condition and passes all tuning tests. Sounds absolutely amazing. Hard flight case included."

Marion Systems Tom Oberheim SEM PRO MIDI&CV SN 0946 w/ Original Box
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
Note Marion Systems on the box.
"This is a Marion System SEM PRO, reissued by Tom Oberheim and purchased in 2016.
It is a one-owner item with no major scratches or damage.
Only the SEM PRO features Tom Oberheim's handwritten signature.
The original box is included, but the internal custom foam padding is missing.
The base of the adapter looked fragile, so it was reinforced with tape. Since it's a 24V adapter, the Marion System logo was laser-engraved to prevent mix-ups.
This adapter itself is made by Akizuki Tsusho. If you prefer a pristine unit, please purchase it directly from them."

Matt Barber - 80's in 80 seconds
video upload by Matt Barber - Sounds from The Sandbox
"Just thought I would try a little something fun...the title says it all. 0 to 80's in 80 seconds. Enjoy. Certified AI free and no traces of softsynths!
Drums - Oberheim DX Stretch, Korg DDD-1 - just a snare on 2 and 4 with mostly just the reverb return from a Roland SDE-330 non-lin setting, Roland TR8S - some perc and a ghost snare from the 707 kit.
Oberheim OB-8
Korg DW-8000
Bass - Roland D-50 patch also triggering a Roland JX8P and Korg Polysix to fatten and double it
Ensoniq ESQ - A nice PPG Wave patch from a sound cartridge I have for it.
Sequential Rev 2 also triggering a bell patch on the Yamaha TG33
Yamaha DX7iiD - nice dual patch one a rhodes type and the other a tine from the many banks on the Hypersynth card to finish it off and play out on."
Matt Barber - 80's in 80 seconds - Episode 2
video upload by Matt Barber - Sounds from The Sandbox
"80's in 80 Seconds Episode 2 has landed! The first one was a bit fun so let's keep the theme going. This one starts off with a nice "groove" and builds with some synths spanning the decade. If you listen past the 80 seconds the Arp Odyssey briefly shows off its duo-phonic capabilities with a few 2 note chords that almost have a vocoder like effect with the phaser on it just after the 2 minute mark.
The following instruments were used and recorded as a 2 track with no editing or overdubs with each part being played into a pair of Arturia Keystep Pro sequencers. As always, AI free and made with real ingredients. Thanks for watching!
Oberheim DX Stretch - main drums
Korg DDD-1 - perc
Roland TR8-S - additional high hats, rim shot, crash
Berhinger - Model D - Bass
Roland Jupiter 4 - Arp
Korg PolySix - Synth Brass Pad 1
Roland Jupiter 6 - Synth layer 2
Yamaha DX7II - Bell 1
Roland D-50 - Bell 2
Arp Solina - Strings
Arp Odyssey Mkii 2810 - Lead"
Matt Barber - 80's in 80 seconds - Episode 3
video upload by Matt Barber - Sounds from The Sandbox
"80's in 80 seconds episode 3 is here to start of the New Year! I thought something "new" should be in 'order' after the busy holiday period. Several familiar sounds in this one that can most likely been dialed in on many synths of the era but this one builds with the hardware listed below. All natural...Certified AI and VST free. Thanks for listening!
Drums -
Korg DDD-1 to start with the first hi-hat
Oberhiem DX Stretch - Main kick, beat kick, snare, additional hi-hat, clap, and rim shot
Roland TR-8S - a little kick for attack, snare ghost notes, and high hat movement
Pad 1 - Oberheim OB-8
BASS - Berhinger Pro 1 and Poly D played with the arpeggio on on the Keystep Pro
Pad 2 - Roland D50 layered with Roland JX-8P and Korg DW8000
Bell - DX 7 ....of course it is!
ARP Chords - Roland Jupiter 4."

Where Digital Meets Vintage Soul
video upload by Jose's Vintage Keys
"This demo explores the overlap between modern digital synthesis and classic instruments. The @GrooveSynthesis 3rd Wave 8M sits at the center, supported by the warmth of the OB-X and the expressive touch of the CP70 electric grand piano. Using presets by @devinbelangermusic and @MattJohnsonskeyspace
I am not yet good enough to program it myself - their sounds are a wonderful start to get to know the instrument and its vast sonic possibilities. #3rdwave"
