Oberheim Legacy: In 1974, Tom Oberheim imagined a small synth as an accessory to his DS-2A digital sequencer. But it was Dennis P Collins, a gifted ARP engineer, who designed the multimode filter of the Synth Expander Module (SEM). This unique filter is a 12 db filter that cannot deny its lineage with the ARP 1047 (ARP 2500) and ARP 2023 (white Odyssey MK1) filters, 12 db filters also designed by Dennis P Collins. With two very fat VCOs and a devastating sync (also close to the Odyssey VCOs), the small SEM offers a powerful sound, very present in the mix and very different from Moog and other synths with 24 db filters. So despite its simplicity and a filter that does not enter self-oscillation, we can get a lot of sounds out of it. Accessible and easy to use, the SEM is a success. In 1975, Tom paired first two, then four, into a huge keyboard case, creating the first "true" polyphonic instrument in history, the "Four Voices." In 1976, the SEM was even expanded to eight. Nicknamed the "White Elephant," its sound was as enormous as the instrument itself! But in 1978, the brilliant Prophet-5 made it obsolete, and Tom designed the OB-X, whose channel cards were also clones of the SEM. Subsequently, the OB-XA and OB-8 used Curtis chipsets and no longer had quite the same sound. In 2010, Oberheim reissued the SEM identically, but with all surface-mount components. In 2011, the SEM PRO added just a MIDI interface.

NRsynth "Solo": This is an "extended" version of the SEM, handcrafted with traditional through-hole components. Only the envelopes have been modified for a punchier result; the rest is identical to the original synth. Additionally, the Solo features a sub-oscillator, a glide, white noise, and many more modulation options than the SEM. MIDI velocity is also supported. Finally, the white metal case gives way to a luxurious, classically crafted cabinet with waxed oak sides and black tolex, similar to a Marshall amp.

A patchbook of all Séraphin Palmeri's sounds is included with the device.

Dream Soundscapes: Korg Minilogue Meets Sonicware LIVEN Ambient Ø

"The Korg Minilogue is in arpeggiator mode, while the Ambient Liven Ø plays a few notes with the Moss by @tybo_ambientsky pattern.
The Minilogue has an additional effect, with the Nocturnal pedal by Collision Devices, which adds delay and depth to the arp.

Mystery Vintage Matrix Pump, Tim Smith DIY & Vintage EML



Pictured are a few interesting items for sale from Mike Berman. You can find them here.

I asked him if it would be OK to capture the pictures here as I've never seen the "matrix pump" before. He gave me the all clear. Note this is the first post to feature one. This is a rare piece of synth history.

All Mike knows about it follows: "For me, the nature of the Matrix pump and its affiliation with EML is pure speculation. I always assumed it to be, at best, an unfinished one-off. If you magnify the photo you can read the labels on the controls and they are intriguing. The multi-pin socket on the left side of the MP accepts the same plug that EML sequencers use. That section is labeled 'Synto Interface'. I experimented with various patches and found some functionality in a few of the controls but I don't recall specifics beyond that. "

Below that you can see The Tim Smith box featuring the following section: Explonental Amp, Noise Generator, Lag Processor, and ENV/Gate Generator. I asked Mike is Tim Smith the same Tim Smith that was the Western Regional Tech Rep for Sequential Circuits , Arp, Moog and also contributed to the famous Vintage Synthesizers book and articles in Keyboard Magazine. He's not sure but believes it is.

Cover JM Jarre Oxygen 14 on Mini Moog | Prophet 5


video upload by Welcome at Jose's Vintage Keys

"Vangelis - Schulze - Hammer ....and #jeanmicheljarre - those are my big heroes. Jarre keeps surprising with music that is both Melodic and Electronic - his soundscapes are always recognizable - but never the same. Prophet played a major part in playing this cover of #oxygen 14."

Crossover Beat w/ Rhodes Mark 2, Prophet-10, OP-1 field, Drums & Bass | Ordeal 2025-03-30 by atnr


video upload by atnr

"A piece created using the Rhodes Mark II, Prophet-10, and ‪@teenageengineering‬ OP-1 field. The Rhodes harmonies repeat in sync with the drums and bass, while the melody goes wild through the MOOD MK II.

On the Rhodes Mark II, I perform with a ‪@BOSSinfoglobal‬ CE-5 chorus effect.

I play the intro and interlude on the ‪@SequentialLLC‬ Prophet-10, adjusting the filter during the interlude.

The drums are recorded and reconstructed in a DAW.

The bass is recorded into the DAW through a SANS AMP BASS DRIVER.

On the OP-1 field, I play the melody while manipulating the ‪@ChaseBlissAudio‬ MOOD MK II CLOCK for pitch shifting. Midway, I adjust the REVERB TIME to create a noisier sound."

'Two Voices' Track recording with AJH Synth MiniMod Eurorack system


video upload by AJH Synth Official

"This was a real-time recording using a 3-VCO, 2 VCF modular system divided into 2 analogue synth voices. I used this system to record 5 tracks for a Bandcamp album, as performances without any overdubbing, yet using a modest amount of modules and gear:



The AJH SYNTH MiniMod system is an authentic recreation of the early R.A. Moog version of the Minimoog synthesiser, whilst some of the other other modules are also based on classic vintage synths. Because of this they can easily fill up a sound space with big, rich and characterful tones. This made them the ideal choice for a recording such as this. Without consciously setting out to do so, this particular track was more inspired by Arvo Pärt and the late Henryk Górecki than anything else.

Modules used:
Vintage Transistor Core VCO x3
Transistor Ladder Filter
Contour Generators
Discrete Cascaded VCA x2
Ring SM
Wave Swarm
Gemini 2412 (dual SEM filter)
Muting Mixer & VCA
Precision Voltages

Controllers:
Arturia Keystep 32
Doepfer Dark Time sequencer

ASM Hydrasynth - Complex Sequences Using KARMA Engine


video upload by LFOstore

"Hydrasynth soundsets: https://lfo.store/product-category/ha...

Korg Kronos is one of the best & deepest modern synths itself.
We recieved our Kronos not so long time ago & already planing series of soundset.

Meanwhile we checked deeply KARMA realtime generator with 2000 (!) patterns and want to show how's it working in connection with other synthesizers.

In this video Kronow midi out connected to Hydrasynth midi in & fiew patterns of KARMA transmits notes from Kronos to Hydrasynth, including realtime kweaking all 8 faders to change different details in midi patterns.

Enjoy the journey!

Standard Lody Acid - Sonicware CyDrums, Volca Bass, NTS-3


video upload by ChrisLody

"You may have noticed the complete lack of CyDrums tutorial on the channel despite being about 2 months since it was launched. Well events have conspired against me a bit on this one, I've just been too damn busy during the week and exhausted at the weekend to get it done. But, fingers crossed, I might have time to get it done soon.

With that in mind I thought it would be a good exercise to refresh my memory a bit on how it all works, so I plugged it in a within a few minutes I'd built a kit and I'd written a beat I really wanted to flesh out which is why this jam happened.

This is kind of my standard fare when it comes to jams like this. I think I've developed a bit of a groove that I tend to find comfy when it comes to the arrangement and I feel I was firmly sat in that today, hence the title. I probably need to learn some new tricks!

I've had the NTS-3 a while but it's not been used enough so far for me to really explore it so hopefully it will pop up more."

"Very good condition Prophet VS + its very rare original memory Cartridge. This one model is truly in a very very good cosmetic shape as shown on pictures. This prophet VS was serviced in 2018 and works fine thanks to a new bright OLED display, new CEM5530's, new Data Entry Slider, some new switches, ... The Prophet VS is a true 'classic-hybrid' of the early nineties with a very unique sound signature. This synth was the original Sequential's venture into the digital era, combining through vector synthesis, 127 digital wave forms with the famous analog filters and envelopes of the prophet 5 legacy. Add to this excellent recipe, a 'sequencer' allowing to combine and or record the 4 oscillators/wave forms and mix them in real-time with the joystick and you get into seriously creative avenues. The result is a wonderful instrument, covering with ease a vast sonic territory, and allowing to reach both very warm analog sounds, evolving pads and landscapes, as well as very rich metallic and bell-like sounds."
