Oberheim's Lost Classic: The OB12 - Synth and Software

video upload by synthandsoftware

"Synth and Software presents: Oberheim's Lost Classic - The OB12. Mark Jenkins profiles a synth that continues to divide opinion after 20 years"


Some of the divide comes from the OB12 being a Viscount virtual analog. Viscount licensed the Oberheim name.

Sound demos come in at 5:36. It kind of reminds me of an Akai AX-60 in character more than a vintage Oberheim. I actually own both, and vintage Oberheim. It has a similar edge to the AX-60. The OB-12 does excel at pads and warm strings. It's an intersting synth.

Noise Synthesizer PRBSynth1

video upload by RS-Elc

"This synthesizer makes sound based on noise and pitched noise patterns.
The sound in this video consists of direct recordings from this synth, no effects are used.
You can build this yourself (some people already did). All information is available and free, can be found at the Elektor Lab pages or my personal website mentioned at the end of the movie"

Vermona E-Piano Vintage Analog DDR Electronic Piano

via this auction

"Electric piano made in East Germany in the late 70s. It's the brother of the Vermona Piano Strings. They share the same body and layout but sound is a bit different. The piano sounds fuller on this one. Harpsichord and Spinet sounds are quite similar. This one has a very nice and deep tremolo buit in, but no triple chorus like its string machine sibling. Also has the same overall and seperate instruments volume control as well as a sustain switch that either make the sound to its longuest sustain or have the pedal control it. A previous owner added a pot (in a not very nice place on the keyboard) that controls the length of the sustain. It's a nice added feature. The unit was serviced. Caps in the power supply were replaced and original DIN sockets were replaced by jack ones for both output and sustain pedal input. It's perfectly working. Condition is fair, there are signs of wear and time but overall still looks good."

Rare Jen DT 73 Analog Electric Piano

via this auction

"This is a the rarest keyboard I ever found. I didn't find any information or picture of it (yes even on Matrixsynth :-). [Funny!]

I estimate it was produced in the early 80s along with the also quite rare Jen SYNX 508 synthetizer and thus is probably one of the very last instrument ever released by JEN. To those wondering it is not a rebadged or revised JEN PIANO 73. I owned one and the circuits are totally different. (pictures available if interested). Noticeably this one has a splitable velocity sensitive keyboard. You can chose between 3 pianos sound that you can assign and layer on the left and right part of the keyboard.

Piano 1 is a very squarish piano sound, kind of EP sound. Piano 2 is the one closest to an accoustic piano sound and Piano 3 is the mandatory harspichord kind of sound. You get a nice built in phaser with depth and speed controls, along with a left/right balance mix, master volume (that controls both the builtin speakers and headphone out but not the external amp out. Engaging a jack in the headphone socket mutes the speakers) and the touch sensitivity control.

This is the real nice feature of the keyboard. I thought the velocity response would be a joke but I was surprised how well it behaves. Not as good as a decent midi keyboard of course but better than most of the mini midi keyboard (like Korg Nano etc) and way way better than the Siel Opera 6 for instance if you know what I mean. Pre midi keyboard with velocity response are usually almost useless IMO. This is the first I found that is playable (far from perfect though).

Soundwise it's not the best electric (well electronic) piano in its genre. Sounds thinner than the ones from the 70s (crumar compac piano, multiman S, Farfisa Soundmaker etc). But with layering, splitting, velocity and phaser you can get some original sounds. I will try to make an audio demo, if not a video one. Condition is quite good considering its age and the overall build quality of italian keyboards from that area. There is a bump on the back of the case where the jack sits but it's barely noticeable. Underneath the keyboard the fake wood covering has started to pull off on both side but it doesn't seem to extend (it's where the original stand is normally screwed in)."

KAWAI SX-210 - Analog Synth Demo | Chord Memory & Envelope Looping

video upload by synth4ever

"Kawai SX-210 analog synthesizer demo and jam, featuring Kawai SX-210 chord memory and envelope looping features. This analog synth music track showcases the Kawai SX-210's chord memory voice stacking and envelope looping to create rhythmic patterns, while the Kawai SX-210 ensemble FX gives lovely stereo width and flanger effects.

The Kawai SX-210 is a single DCO analog polysynth from the early 1980s with SSM filters and a number of other interesting features. Be sure to check out my review of this synth here: [posted here]

Hope you enjoy this synth jam and demo of a Kawai SX-210 single patch in chord memory mode."

A polyphonic in 1974? THE ANSWER

video upload by AutomaticGainsay

"Have you spent a week wracking your brain and biting your nails in regard to the previous video that proposed the preposterous idea that there was an instrument capable of polyphonic synthesizer sounds the year before the modern polyphonic synthesizer became a thing? Well, in this video, THE ANSWER IS REVEALED."

Update: also check out the Conn Electric Band from 1974.

SOMA Pulsar-23 // Hauntingly Beautiful (not only as a drum!)

video upload by Dexba

"I finally did it!
I've never waited so long for a video to come out since I bought an instrument, the turnaround is usually one week, I think for this we're closer to 6 months.
But a lot of stuff happened, I moved, I've left many instruments behind, but I decided to take with me this, probably the most obscure and the one I have least confidence with.
Finally, I cracked the (very personal) code, of using the Pulsar like a very different and powerful Lyra, instead of a drum machine.
I made many previous attempts, but I was always ending up with trip-hop borderline eurorack farts and bubbles, and it wasn't quite video material.
Now, that's mine, that's what I like from my instruments, and I love the Pulsar even more for being able to get me *THERE*.
For any discussion about the process or the gear, I'll wait for you in the comments :)
Enjoy ✨"
