FREE SYNTH: OB-Xf (Oberheim OB-X Emulation) - No talking demo

video upload by ADL-MusicLab

"Hi, everyone!

OB-Xf is a continuation and modernization of the last open source version of OB-Xd by 2DaT and later discoDSP, bringing together several efforts going on in the audio space and combining them inside the Surge Synth Team infrastructure.

It is an amazing freely downloadable virtual synthesizer inspired by the venerable Oberheim OB-X.

The original Oberheim OB-X is one of the best analog poly-synths ever, used by Rush, Van Halen, Queen, Japan, Eurythmics, Ultravox, Tangerine Dream and many others.

It is a classic synthesizer with a timeless sound that continues to captivate musicians and producers alike. With its rich, full-bodied tones and expansive sound design capabilities, the OB-Xf is the perfect choice for those looking to add a vintage touch to their music.

The OB-Xf is a synthesizer that has been designed to recreate the sound and behavior of the Oberheim OB-X, OB-Xa and OB-8. However, the architecture of the original instruments was limited in some ways, so the OB-Xf includes a number of additional or altered features. Overall, the OB-Xf has been designed to produce a sound that is as good and as rich as the original OB-X.

Also, like many synths of the OB-X's generation, the OB-Xf has no internal effects so its sounds and textures can be greatly enhanced by the use of additional processing like chorus, reverb, delay, etc.

In this demo I will just let you hear what some amazing sound designers have made for this stunning synth simply by scrolling and playing some beautiful presets.

No additional effects or outboard processing here. What you listen is what you get!

BreakBud - Synth Breakbeat Pad Machine

A new app in via Cem Oclay

"Build Rhythms Fast with Pads and Sequencing

The 4x4 pad grid gives you 16 playable pads, each with its own full sound, pattern, and groove setup.

Switch pads instantly to move between variations without stopping the flow.

The step sequencer gives you direct control over steps, velocity, and timing.

Each voice can use its own step count and rate for polyrhythms, uneven loops, and evolving patterns.

Swing, nudge, and humanize make it easy to dial in a tighter or looser feel.

- 6 synthesized drum voices (100% synth, not sample based)
- 16 pads where each pad has its own sequencer pattern and parameter locks
- Super flexible sequencer where each row can have 1-16 steps (polyrhythms!) and microtiming with swing+nudge+humanizer combo
- A sweet, algorithmic pattern generator
- Full MIDI compatibility (pad in, pad out, voice in, sequencer out)
- AUv3 multiout support per drum voice"

Roland JX-70 / JX-10 rack mount note to LED addition

video upload by Craig Barnes

"I had finished this project, but originally the 16 patch and bank buttons were dual LEDs. Today I started to replace them with blanks and thought, what if I leave patch buttons 1-6 as dual LEDs and add a simple processor to intercept the serial Comms between the assigner board and the voice boards. Effectively creating a midi to trigger to display the notes as LEDs."

Acid - Novation Circuit Tracks Sound Pack by A Force Truly Evil

video upload by A Force Truly Evil

"Available here: https://sci-fiaudio.com/product/acid/

YOUR NOVATION CIRCUIT TRACKS — REBORN AS A MODERN ACID MACHINE. FROM TIMELESS ACID HOUSE TO RAVE TECHNO

ACID transforms your Novation Circuit Tracks into a modern Acid machine, designed for genres such as Classic Acid, Acid House, Techno, Detroit Techno, Acid Techno, Hard Techno and Rave genres.

Roland TB-303 behaviour emulated — with a more modern sound, yet fully capable of delivering the classic tone. Modernised and expanded.

The pack includes 128 patches in total:
96 authentic 303-style Acid sounds plus 32 additional sounds, including a strong selection of polyphonic material such as chords and classic genre sounds to expand your productions beyond classic monophonic Acid lines.

All patches respond to velocity where appropriate, allowing expressive control and dynamic performances directly from the Circuit Tracks pads.

The 303-style patches are programmed to recreate the behaviour and response of the original machine — from timeless Acid House to harder Acid Techno and underground rave territories — featuring velocity-based accent behaviour, glide response, LFO modulation for evolving movement, and powerful modern distortion algorithms with delay and reverb send effects.

Completed with 64 drum samples (House, Techno, Hard Techno, 707, 808, 909 and more), ACID becomes a complete production toolkit — effectively turning Circuit Tracks into a purpose-built Acid production machine."

"🔥 Energetic Techno Groovebox Jam | Dawless Performance

In this video I perform an energetic techno groovebox jam using two powerful machines: the Novation Circuit Tracks and the Novation Circuit Rhythm. This dawless techno setup shows how these two grooveboxes perfectly complement each other in a live performance environment.

Both Circuits handle rhythmic and melodic elements, creating a full techno track entirely from hardware sequencing. The Circuit Tracks provides synth parts and sequencing, while the Circuit Rhythm adds powerful drum patterns and sample-based grooves. Everything is performed and sequenced live on the devices, making this a true hardware techno jam .

The final mastering of the track was done in Ableton Live to polish the sound while keeping the raw energy of the live performance.

If you enjoy dawless techno jams, groovebox performances, and electronic music hardware, this setup is a great example of how compact gear can produce a powerful underground techno sound."
