BERLIN SCHOOL Schulze Style: Improvise & Overdub - All analogue eurorack modular sounds

video upload by AJH Synth Official

"Inspired by the way Klaus Schulze sometimes constructed his recordings. Those lengthy, iconic performances were often partly improvised, starting with a sequenced 'jam', mostly with his "Big Moog" modular system, then building upon it with overdubs of other sounds and musical parts. He would use many instruments; Arp, Moog and EMS synths among others, but here just a selection of AJH Synth eurorack modules are used, and a shorter, simpler piece of music, with just a couple of overdubbed parts.

INTRO SOUNDS: This patch used the LADDER FILTER and the FIXED FILTER BANK 914 to process pink noise independently, but both pass through the filter bank by way of its CV-controlled mixing functionality. Multiple envelopes cause the sound to evolve as it crossfades between the output of the ladder filter, and then the filter bank's two groups of frequencies (left and right) one after the other. This creates an effect reminiscent of a long, unnatural reverb tail.

SEQUENCER PART: This patch also makes use of the FIXED FILTER BANK 914's two groups of frequencies, both independently and combined, divided between two VCAs in a stereo configuration. This, later combined with the ENTROPIC DOOM, is modulated by synced, random voltages from the TAP TEMPO VC-LFO, and step probability from the CHANCE DELAY, so that the brighter, more percussive steps are random in tone and occurrence.

SOUND EFFECTS: This was inspired by the sound of morse code and old analogue radio communication signals. For that it uses the LUNAR MODULE to add 2 types of noise and some low fidelity to the sound of an incoming VCO responsible for the 'beep' tone. The DUAL RVG and TAP TEMPO VC-LFO create random 'beep' lengths prior to entering the Lunar Module.

VOCAL/CHOIR: This is three VCO's modulated separately and passed through the FIXED FILTER BANK 914. See our guide to using the filter bank for these kinds of sounds here: [posted here]

BASS: This is two VCOs and white noise from the GLIDE + NOISE module going into the RING SM, where a -1 sub octave is generated and added to the mix. It uses the TRANSISTOR LADDER FILTER for that famous Moog/Minimoog warm fatness. Some of the low frequencies had to be scooped off in post as web video compression simply wouldn't cope with it! This floor-shaker of a combo never disappoints. The Ring SM's unique sub-bases (shaped square waves) add almost bottomless depth to an already legendary fat filter and very rich, vintage-voiced oscillators.

LEAD/SOLO: My struggling attempt to mimic just a little of Klaus Schulze's lead style... Sorry Klaus! This uses 3 VCOs and white noise going into the TRIPLE CROSS, where an LFO is modulating the mix of 2 VCOs (pitched differently), and the output sent to the GEMINI 2412 dual SEM-based filter, which is used in a stereo configuration to separate VCAs. An LFO modulates its two VCFs in opposition to each other, creating a stereo panning effect.

Intro to The NDLR (rev2) Motif Gate Control & Perlin Noise Pattern Generator

video upload by Conductive Labs

"Coming soon for The NDLR (rev2) (finally) a Gate control for the Motif parts. We plan to release a beta of the firmware on our forums before end of Nov 2024. There was lots of code refactoring under the hood to enable this feature and others planned for the future, so a beta test is warranted before release.

See https://conductivelabs.com for more info on our line of MIDI widgets made for synth-heads"

PWM Mantis // It's not a synth.. it's a time machine // Review and Demo

video upload by Starsky Carr

"PWM's Mantis has done it again, given us a very unique and characterful synth full of vibe. Its a mono/duo/quad hybrid, with digital oscillators (16 in total), 2 analog filters and a whole host of really interesting bits and pieces.

Following in the Malevolent's footsteps it continues PWMs affordable ethos, while hammering home a tonne of vintage tones. Thenraw sound of this is gorgeous and they've not smoothed the rough edges too much which gives us some Microwave, Prophet VS, PPG digital sheen."

Rare Gleeman Pentaphonic

"Very Rare.

Serviced by Vintage Synth & Co in Paris.

Everything works perfectly.

The Pentaphonic is a five-voice polyphonic analog synthesizer released in 1982. It was designed by brothers Al and Bob Gleeman and featured three DCOs for a stable and juicy analog sound. The Pentaphonic was in the running against such classics as the Sequential Prophet-5, Moog Minimoog and Polymoog, and the Oberheim 4-Voice. But the Gleeman Pentaphonic (and the Pentaphonic Clear) are extremely rare! Only about 30 Pentaphonics and 20 Pentaphonic Clears were ever made."

"ARP - Model 2600 Synthesizer - Early 70s USA Synthesizer w/ 3620 Keyboard - x0962 - VINTAGE

The ARP 2600, introduced in the early 1970s, is a semi-modular analog synthesizer that became a cornerstone in the world of electronic music. Designed by Alan R. Pearlman and his team at ARP Instruments, this synthesizer was renowned for its versatility and rich sound. Unlike fully modular systems, the ARP 2600 came pre-wired, allowing musicians to play it straight out of the box while still offering the flexibility to reconfigure its signal path using patch cables. This made it accessible to both beginners and seasoned synthesists. Its robust build and portability also contributed to its popularity, making it a favorite for live performances and studio work alike.

One of the standout features of the ARP 2600 is its built-in spring reverb, which adds a distinctive depth and character to its sound. The synthesizer includes three voltage-controlled oscillators (VCOs), a voltage-controlled filter (VCF), and a voltage-controlled amplifier (VCA), providing a wide range of sonic possibilities. The ARP 2600’s ability to produce everything from deep basses to soaring leads and complex sound effects made it a go-to instrument for many iconic artists and sound designers. Its influence can be heard in numerous classic tracks and film scores, cementing its legacy as one of the most important synthesizers in music history."
