Everything you wanted to know about the LOGAN VOCAL SYNTH but were afraid to ask

video upload by Vintage Audio Institute Italia

"We finally found a Logan Vocal synth - and since this incredible unicorn doesn't get captured very often we thought the internet deserved quality photos and a video demonstration of all its functions. Or most of them - we actually missed a few features so stay tuned for a Part II later this summer.

Most of the info is in the video already but a quick introduction and recap would go something like this:

Logan Vocal Synth
weight 50 kilos
61 keys and 61 slider potentiometers

The upper panel is dedicated to :
instrument selection buttons, panning left and right, the monophonic and polyphonic synthesizers and their modulation controls.

The front of the panel is dedicated to the instrument sections Strings, Piano and Voice.

The architecture of this instrument is unique and might have been a bit of a gamble that sometimes worked out great and sometimes less so.
Our service technician had to slightly change the trigger circuitry to render the triggering of the notes more reliable and generally stable.
We also decided to non-invasively modify the split point to continue down to the lowest note on the keyboard instead of starting over two octaves up at the 24th key and below.
You operate this with the foot pedal switch, and it can be disengaged to return to the factory setting.

Some of the engineering wonkiness was decided to be kept though and you can hear the fluctuations, a slight tremble, in a lot of the sounds."

Moog Mariana 50 Dynamic Presets. No Talking Sound Demo

video upload by Anton Anru

"Sequentizer is a collection of 50 patches for the Moog Mariana VST synthesizer, including 21 basses, 22 leads, and 7 textures.
🎼 This soundset is dedicated to rhythmical timbres.
Moog Mariana features dual-layer architecture, six LFOs, and four random generators. By combining different modulation waveforms and speeds, it's possible to create rich, evolving, and rhythmically driven sounds.
Simply hold down a key or MIDI note — and the pattern plays itself.

📦 Get these presets: https://antonanru.sellfy.store/p/mari...

🥁 That’s the concept behind the name Sequentizer: while Mariana doesn’t include an internal sequencer, these patches are programmed to simulate complex sequences and rhythmic patterns through modulation alone.

💎 The soundset explores a wide tonal spectrum: warm, deep, soft, clean, punchy, dark, bright, aggressive, distorted, detuned and others.
🎚 The ModWheel brings additional expressiveness — brightening the tone, introducing detune, or expanding the stereo field depending on the patch.

🧿 These presets are versatile and suited for a broad range of genres: ambient, electronica, cinematic, retrowave, synthwave, darkwave, IDM, trip-hop, lounge, downtempo, pop, chill out, new age, trance, deep, progressive, techno, breaks, jungle, drum and bass, dub, and more.

💡 Make sure you’re using the latest version of the plugin to ensure compatibility.
To install the presets:
Open the preset browser pop-up menu (top center of the plugin).
Click “Open Presets Folder.”
Move the downloaded presets into this folder.
Restart the plugin — the new patches will appear under the User category."

EML ElectroComp 101 – Vintage Duophonic Semi-Modular Synthesizer

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

via this Reverb listing, also on eBay

"A rare and revered classic, the ElectroComp 101 was Electronic Music Laboratories’ evolution of the original ElectroComp 100—crafted by the Connecticut-based company known for its educational and experimental instruments. Released as a flexible alternative to the ARP 2600 and Minimoog, the EML-101 brought serious innovation to semi-modular design.

Unlike its contemporaries, the 101 featured four voltage-controlled oscillators—two of which operate sub-sonically for LFO duties—with morphable waveforms accessible via rotary selectors. It’s duophonic, allowing up to two-note polyphony, and provides a unique modulation architecture where control voltage and audio signals are treated interchangeably, offering highly creative patching possibilities.

A 12dB/oct multimode filter (low-pass, band-pass, and high-pass) with resonance adds tonal versatility, and the onboard ring/amplitude modulation, sample-and-hold (“Sampler”), and dual envelope generators give the 101 deep sound-shaping power. Thanks to its use of op-amps instead of temperature-sensitive transistors, the 101 also boasts impressive tuning stability compared to Moog or ARP synths of the era.

Designed with portability in mind, the unit folds neatly into its own wooden case, making it ideal for studio or stage use.

Originally marketed to universities and educational institutions, the EML-101’s modular flexibility, rich analog tone, and rock-solid build quickly caught the attention of professional musicians and sound designers, cementing its place as one of the most powerful portable synthesizers of the 1970s.

Features:

Polyphony: Duophonic

Oscillators: 4 VCOs (2 with sub-audio range; variable waveforms + noise)

Filter: Multimode 12dB/oct filter (low-pass, band-pass, high-pass) with resonance

Envelopes: 2 ADS generators

Effects: Ring/Amplitude Modulator, Sample-and-Hold

Modulation: Any CV or audio signal can be patched freely

Keyboard: 44-note

Control: CV/Gate compatible

A previously used item that shows signs of cosmetic wear but is fully operational and functions as intended—a vintage gem ready to inspire."

Pure Analog Polyphony with the VAEMI Modular System #eurorack #osiop #xfmr #vca #subtractive #synth

video upload by Vaemi

"Pure Analog Polyphony with the VAEMI Modular System
Most polyphonic synthesizers are hybrid designs that combine digital control with analog sound generation. In modular systems, however, building a truly pure analog polyphony can be both challenging and deeply rewarding.

In this video, we created a fully analog polyphonic structure using the VAEMI modular system. We used sawtooth waveforms on all oscillators. With 3 OSI-OP modules, we achieved 3-voice polyphony. By using VAEMI Analog Sequencers, we provided dedicated voltage control for each oscillator, resulting in a completely analog polyphonic sequencer.

The signal path was processed through our prototype analog filter module, creating a classic subtractive synthesis architecture. The entire system was synchronized via clock signals from the Beatstep Pro. The final recording was passed through an RE-201, adding a classic tape delay and spring reverb atmosphere.

Sometimes, chasing sound takes you back in time.
This pure analog polyphonic structure we built with VAEMI blends the feeling of the past with the modular technology of today.
You'll know what we mean when you hear it."
