Electronic Music Laboratories Electrocomp EML-101 SN 475

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"This is a very rare Electrocomp 101 (Serial # 475) in a very good condition. It has been fully serviced and has no issues whatsoever.

I'm the third owner of this unit. Some mods were done in the 1970's by John Phelan, one of the engineers @ EML which makes this unit totally unique. Here's the functionality of the added 3 switches:

The switch near the Glide Control, multiplies and lengthens the glide time as the pitch slides from note to note. The switch below the filter turns the BP (bandpass) filter setting, into band reject (meaning it provides highpass and lowpass filtering simultaneously).
The switch next to the mixer changes the character of the noise (from white to pink)
I took great care of the unit and used it only in my studio. I'm selling it because I'm simply not using it at all. This 101 comes with original manual and documentation."

Note SN 475 was listed back in 2014.

Not a fan of the movie but this track is beautiful.

Additional SYNTH CITY Listings

"This monstrous synth is in great shape and sounds fantastic. There are eight analog voices which can be panned individually for some really interesting stereo sounds. The keyboard can be split or doubled and there are two oscillators per voice. It is a very warm sounding synth great for massive chords, basses and leads. This model has MIDI in out and thru.

It is quite a beast, with all the great 80s vibe and that classic Oberheim sound. In fantastic working and cometic condition overall. Serial No. 050516

Service notes:

-Replaced firmware IC
-Replaced several failied CMOS logic chips
-Recapped bend assembly and processor pcbs
-Repaired D/A converters on voice boards
-Cleaned panel controls
-Fully calibrated
-Repaired autotune circuit
-Replaced missing hardware"

Steiner-Connolly Synthacon SN 0010

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"Am extremely sad to sell my Steiner-Connolly Synthacon

This was handmade by Robbie Connolly (The Killers) and his team under the direction of his neighbor Nyle Steiner who built and designed the original Steiner-Parker Synthesizers in the 70's. Made with real through hole circuitry and manufactured by a small team in Provo, Utah these are as luxury of a synth as you can get.

I had the pleasure of working on their team which is where I earned this, but now must part ways with it to pay off some debt.

I am really not eager to part with this, so it's priced accordingly...

Everything works, no visible imperfections I am aware of. Been kept in my home studio.

This is serial number 10, and I am unsure as to whether they're making more of these or not..."

OP-XY Generative Sequence on Vermona PerFourMer mkII // Ambient Jam

video upload by Mark Cee

"Its been a long time with out my friend the Vermona Perfourmer. Pulled it out and decided to share some music. The OP-XY is sending a generative sequence. OP-1 Field recorded a few bars of this and slowed down by 50 percent for a pad. FX are the new Slate & Ash Halo, Arturia Ocean Reverb, and a new Reverb called REVERSIDE (former designers of 2c audio Ather i believe)."

The Crow Hill Company Introduces ARCANE STRINGS

video upload by CROW HILL

Press release follows:



EDINBURGH, UK: readily representing its first ‘big’ release in over a year (when the temporarily out-of-circulation GLASS STRINGS was effectively re-released with a totally redesigned GUI and added features as the Edinburgh-based enterprise’s workhorse string library for a new era in more human-sounding music and scores, coinciding with rebranding itself with an aesthetic that truly realised company co-founder and composer Christian Henson’s heartfelt dream of encouraging people to make music and help them on their journey, regardless of whatever point they were at and wherever their journey began), The Crow Hill Company is proud to announce availability of ARCANE STRINGS — taking the sampling rule book and ripping it up, ultimately resulting in a string library featuring amateur players in order to achieve an arcane, primitive, dislocated, microtonal, loose, and sometimes savage sound duly designed for media composers wanting to leave a truly characterful imprint on their next drama score, or, indeed, composers who want to gain extra devilish bite out of their existing string collections — as of August 14…

Minimal Audio Current 50 Atmospheric Arp Presets. Sound Demo

video upload by Anton Anru

✨ "Dreaming Motion" is a bank of 50 Arp Presets for Minimal Audio Current 2, combining warm analog-inspired sounds with soft and airy atmospheres.
The collection moves between retro synth character, subtle analog imperfections, dreamy textures, and spacious evolving arpeggios, giving the bank both nostalgic and modern sides.

📦 The download link: https://antonanru.sellfy.store/p/curr...
👤 The author of the soundset is Ilian.

🎛️ Each preset features 4 Macros for shaping the sound, while the Modwheel adds additional movement and expression.
The macros are a significant part of the soundset. They can change tone, stereo width, modulation depth and rate, noise level, distortion, detuning, space/echo/reverb, effects mix, envelope parameters, and others.
You may control them via MIDI controller, use them for automation, or map the macros to your DAW modulators like LFO, Shaper, and others.

📻 The patches are perfect for Electronica, Synthwave, Ambient, IDM, Downtempo, Melodic Techno, Chillout, and experimental electronic music.

🎹 All Arps are designed in either C Major or C Minor, following Current 2’s tonal Arp system. This makes the presets easy to use while keeping their harmonic character consistent. You can change the Scale in the lower right corner of the synthesizer to the one used in your track.

"A high water mark for glassine pads, premier brass stabs, and surprisingly present basses, the Roland Juno 106 is well deserving of it's status as a classic synthesizer. All voices have been refurbished, this is a fully working specimen, with all sliders and pots cleaned and working wonderfully. Physically, this unit is in very clean condition with average panel wear.

Service Notes:
New set of voice chips (Rosen Sound 80017a clones)

Living the Euclidean Dream - A Hands-Off Eurorack Patch

video upload by Scrapcode Modular

"A slow, relaxing musical meditation on Eurorack. No post processing - audio goes straight from the rack's headphone output to the camera input.

Patch notes:

Audio signal flow:

4x Osciallators from @scrapcodemodular QUORD - Chord Sequence Oscillator (prototype)
into
4x inputs of Doepfer A-105-4 Quad Poly VCF (low pass filter)
into
4x inputs of @behringer Four Play VCA
into
4x inputs of @Dreadbox-synths Psychosis (adding panning movement and delay effect)
into
Stereo input on @behringer rack mixer (adding stereo chorus/reverb effect)
into
Stereo input on camera

Envelope modulation:
@scrapcodemodular WONK - Quad Envelope Generator is controlling both the VCF and VCA for each of the four notes individually. This is being triggered by the @scrapcodemodular AXIOM - Euclidean Rhythm Generator, which is set to a 15 step pattern. The trigger for the bass note is multed to the QUORD's 'Play Next' input to progress the chord each time a bass note is played. This gives a slow 12/8 feel due to the 8 chord sequence, but as AXIOM is running over 15 steps, any repetitions in rhythm are spread throughout the pattern rather than being repeated each bar.

LFO modulation:
As well as the Psychosis adding stereo interest, slow LFOs have been patched into various parameters on AXIOM to keep the rhythm changing - not so much as to be jarring or unfamiliar, but enough that the same order of notes almost never repeats. Further cyclical modulation has also been applied to the WONK parameter (changing envelope timings) and the filter's cutoff frequency. LFOs have been attenuated using @scrapcodemodular QUATT - Multenuverter."
