Sequential Circuits Prophet T8 Vintage Analog Synthesizer

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

via this eBay listing, also on Reverb

"The Sequential Circuits Prophet T8 is a flagship 8-voice analog polysynth renowned for its luxurious wooden keyboard with fully assignable polyphonic aftertouch, giving unparalleled expressive control over each note. Combined with its flexible modulation routing, rich analog tone, and premium build quality, it’s a dream instrument for players and sound designers seeking both power and nuance.

The synthesizer is in good cosmetic and functional condition. Factory presets have been loaded. One pot and two knobs are not original. The keybed action could benefit from restoration (new foam/felt, adjustment) as it feels a bit clunky and the lowest black key is sticking. However, it's still quite playable and all keys and pressure pads work. Voices are in tune and sound good."

Roland S-1 | Synth Sound Design

video uploads by Mark Young

Playlist:

1. Roland S-1 | Synth Sound Design Basics Tutorial | Master the S-1: Ep. 1

This is the first video in my series on mastering the Roland S-1. In this episode, I cover the essential sound design features of this powerful little synth. Future videos will dive into advanced sound design, creative jamming techniques, sequencer tricks, and anything else you’d like to see.

2. Roland S-1 | Advanced Sound Design Tutorial | Master the S-1: Ep. 2

The S-1 has a hidden super power: Custom Waveforms. Using the oscillator draw function you can input your own custom waveforms to create new sounds you wouldn't expect from a mini-SH-101 clone. I have a few that I use all the time and I wanted to share them with you. I hope you enjoy!

3. Roland S-1 | Sequencing Tutorial | Master the S-1: Ep. 3

The Roland S-1 sequencer isn't the most advanced, but it offers a surprising amount of utility for its small size. For me, the S-1's sequencer is a quick and effective way to capture ideas and jam, in ways that even more advanced synths and grooveboxes don't always inspire. I get a lot of enjoyment from punching in patterns on the S-1 and using the tips and tricks I show in this video to create tracks and explore new ideas through jamming.

The Roland S-1 has four voice modes which can be used for different sound design purposes. I received a lot of requests to make a video on the chord mode functionality, so I figured I would expand it out and cover all of the different S-1 Voice Modes. I'll dive into each one mode and give some ideas for how to use them, with emphasis on chord mode. Let me know if you have any questions!

Weston Precision Audio: SV1 & SF1 | Full Demo and Review

video upload by Happy Mag

"Tasteful design and even tastier tone — that’s Weston Precision Audio! 🎛️
Met Devin at Buchla and Friends earlier this year and it was an absolute treat 🙌

Starting with the SV1: a dual stereo VCA with both vintage and clean paths — four VCAs in total 🔥
Vintage brings warm saturation with discrete transistors, while the clean side is modern, transparent, and tight 🎯
Run it in mono or stereo, link controls, bias your CV, and boost gain up to +6dB.
Need grit? Crank the input or flip the Overdrive switch for creamy distortion or sharp clipping 💥
And yes — zero-crossing detection eliminates clicks from fast envelopes. Smooth as 🧈

Next up: the SF1, a stereo or dual-mono VCF with two identical 4-pole filters.
Switch between LP, HP, BP — or tap into notch, all-pass, and phaser outputs too 🌈
Link the filters or keep them independent. Modulate everything, shape stereo motion, or use it as a sine oscillator with 1V/oct tracking 🎶
It’s a filter, it’s an oscillator, it’s a full-on sound design weapon 🧪

Head to WestonAudio.com to dive deeper.
And shoutout to Pig Hog for keeping the patch bay clean 🐗⚡️

Special thanks to Pig Hog for the cables!

Frap Tools: BRENSO | Full Demo and Review

video upload by Happy Mag

"The Frap Tools BRENSO is more than just a dual oscillator—it's a modern homage to the west coast synthesis tradition pioneered by Don Buchla in the 1970s. As a complex oscillator, BRENSO offers a dense web of internal modulation, wave shaping, and signal routing options that invite experimentation, creativity, and highly expressive sound design.

Let’s break down what makes BRENSO special—and why it’s a standout tool for modular synthesists and the perfect place to start Happy Mag's Synth Month 2025 journey!

🧠 What Is a Complex Oscillator?

In synthesis terms, “complex” usually refers to waveforms that go beyond simple shapes like sine, triangle, square, or sawtooth. These richer, more dynamic tones are achieved through audio-rate modulation—one oscillator affecting another at high speed to produce new, harmonically rich content.

To that end, BRENSO includes two triangle-core analog oscillators, each with four outputs. These oscillators are designed to interact, cross-modulate, and shape each other in ways that transform simple waveforms into entirely new sonic terrain.

🎨 We Love the Colour-Coded Interface!

One of BRENSO’s most elegant features is its colour-coded layout. This isn’t just for show—it reflects functional sections of the module, making navigation and patching intuitive:

🟢 Green Section – Frequency control for oscillator one
🟡 Yellow Section – Frequency control for oscillator two
⚪ White Section – Timbre shaping (via wavefolders and shapers)
🔴 Red Section – Amplitude control (via a four-quadrant multiplier for AM/RM)

These sections are organised spatially and visually, so once you understand the color scheme, you're halfway to mastering the module.

🔄 Modulation Without the Patch Cables

BRENSO encourages semi-normalled patching. Many modulation paths are internally routed by default using dashed lines on the panel. For example, the green sine wave is often pre-routed as a modulator for the yellow oscillator—no cable required.

This internal routing makes it easy to get rich interactions going quickly, but BRENSO never limits you: patching a cable into a jack overrides the normalization, giving you complete flexibility.

Erica Synths: Hexinverter Mutant Drums | Full Demo and Review

video upload by Happy Mag

"The Mutant Drum Line lives on! When Hexinverter shut its doors in 2022, the future of those gloriously twisted Mutant modules looked bleak — but Erica Synths swooped in, reverse‑engineered every circuit, and gave the whole lineup a second life with modern muscle.⁠
⁠
🥁 Mutant Bassdrum — pure 808 thump or fuzzed‑out speaker‑ripper thanks to batteryACID distortion. CV everything, stay clean or filthy.⁠
⁠
🎯 Mutant Snare — twin bridged‑T oscillators + snappy noise + switchable HP/BP filter = crack, glitch, or full‑roar chaos. External audio input turns it into its own percussion synth.⁠
⁠
💥 Mutant Rimshot — three oscillators, multimode VCF, and HI/LO/CLV voicing. Flip the range switch for deep FM clangs or classic 909 clicks.⁠
⁠
👏 Mutant Clap — LFSR‑driven 909 clap that mutates into bleeps, broken textures, or lush analogue‑reverb tails. Dedicated NOISE out and Drive for extra crunch.⁠
⁠
✨ Mutant Hihats — true analogue open/closed hats with per‑voice Drive, choke switch, resonant BPF, and external noise input. Classic shimmer to future grit.⁠
⁠
🎚️ Drum Mixer Lite — six channels, LED metering, switchable AUX send, plus a vactrol compressor that glues (or crushes) your kit into one punchy monster.⁠
⁠
Hexinverter’s DNA, Erica Synths’ engineering — same mutant attitude, new‑school reliability. Ready to patch, perform, and terrify your neighbours. 🔊⚡️⁠

Behringer Syncussion SY-1 Analog Drum Patches + Samples Demo

video upload by Anton Anru

"🥁 Analog Drums is a collection of 50 patches for the analog drum synthesizer Behringer Syncussion SY-1, featuring 12 Kicks, 8 Snares, 10 Toms, 6 Cymbals, 6 FX, and 8 Percussion sounds.
🔮 This soundset was born from an exploration of this retro-style drum synthesizer, crafting everything from classic, production-ready tones to more experimental percussive timbres. The result is a dual package: a patchbook plus 250 one-shot samples.

📦 Get the soundset: https://antonanru.sellfy.store/p/sync...

💾 Each patch served as a starting point from which several variations were recorded by slightly tweaking parameters. This way, you get not only a guide to recreating the sounds but also a ready-to-use WAV collection (44.1kHz / 24-bit) for both hardware samplers and DAWs.
The collection is suitable for many genres: synthwave, retrowave, techno, deep, house, downtempo, industrial, and many others — anywhere an analog retro sound is needed.

🎹 The Behringer Syncussion SY-1 can be triggered not only via the TRIG button or external trigger but also through MIDI. When connected to a MIDI keyboard, the keys transpose the pitch of the patch—experiment with different notes, octaves, and sequenced patterns to unlock a broad sonic range. Tweaking parameters during performance adds dynamic movement and expressiveness to your percussion lines.

📒 The soundset comes in a PDF format. Following the guidelines while experimenting with the suggested settings will deepen your understanding of the synth’s capabilities.
🎧 Each patch also includes an audio example to demonstrate its intended sound.

I added synth parts to the demos. They are not included in the soundset.

"Prepare to meet SoundThread - capable of the most insane sound mangling imaginable - and it's completely free. You might know of Composer's Desktop Project, used by our old pal Aphex Twin on Drukqs. CDP is one of the most powerful software sound design tools on Earth, and is free. It can do things you just can't do elsewhere. Problem is, CDP has never been especially easy to use. Enter SoundThread - a new, beginner friendly Mac/Windows/Linux "front end" for CDP. SoundThread gives you access to lots of CDP's power, but in a simple drag-and-drop modular way. It makes it fun and quick to explore, even if you have very limited experience - that's a big deal. CDP has never been this easy before.

This video was made completely independently of SoundThread & CDP - if I find something cool, I just want to spread the word.
