ODD-1 Demo: Live Mode with Cassette Tape

video upload by Oddment

"I have a box of old cassette tapes. I wanted to show how you can mess with the playback speed and pitch even in LIVE mode on the ODD-1, and show off one of the fun effects you can create with TIME PATH. I had no way to prepare myself for the glorious content to be found on this tape!

The ODD-1 is a microsonic (granular) instrument — a synthesizer that chops sound into small pieces and lets you re-pitch and rearrange them, with a knob for every function required and patching by holding any knob down.

Chapters:
0:00 — Intro
0:20 — Basic setup
0:56 — Modify playhead speed and grain size, spacing
1:15 — Pause live mode
1:50 — Un-pause
2:20 — Using TIME PATH to freeze the release
2:45 — Close"

All the emulators are original work by TUS, except the SC-55 emulation core which is originally based on the work of NukeYKT."

"88Emu emulates the hardware inside most Sound Canvas modules and related earlier sound generators, used for retro gaming and DTM. It runs the original firmware on emulated CPUs and sound chips, including the firmware’s instrument selection, voice allocation, effects, MIDI handling and front-panel behavior. You supply the ROM images; they are not included.

88EmuPlayer is NOT a DAW-compatible plugin, but instead a standalone application for playing MIDI files and using those devices from a MIDI keyboard, sequencer or game. 88EmuCli uses the same emulation to render files to WAV offline using a command line interface, without having to wait for the song to play in real time."

Oberheim Teo5 “Cinamatique” Preset (Violins in my Mind)creating an Instrumental using Step Sequencer

video upload by Maria Calfa-DePaul

"This synth is quickly become one of my favorites. I think if I had to sell all of them, I definitely would keep this one. It is just got such an incredible sound. It feels like an instrument not a synthesizer. Don’t know if that makes any sense but it feels so real feels like you can do so many different types of music with it and I’m enjoying having it and going back to it. I can’t play everything all at once so I like to give my synthesizer and Instruments a little bit of love whenever I can And in this track, I use the preset Cinematique and I use the step sequencer with some rest to kinda get it to the tempo that I wanted and it seemed to work really well. I really felt like this could be background music or used for scarring a movie. You know I mean, I love the sound of the synthesizer and I hope it comes through and I hope you felt relaxed and enjoyed watching it."

Fieldtone Weaver | Drone Sound Experiment No. 2

video upload by The Pedalboard Orchestra

"This is the last track of my little series of sound experiments with samples from the Fieldtone Weaver and modulation from the Kinotone Ribbons, Alexander Pedals Forget Me Not and AC Noises Ricorda.

This one is more of a meditative drone. The Fieldtone Weaver is an incredible sound machine that works perfectly with a set of ambient effects pedals.

GODWIN CD2 - 1980s - The First Ever Demo Of Rare Apparatus

video upload by Vintage Audio Institute Italia

Note this appears to be the first post to feature the GODWIN CD2.

00:00 Setting Up
00:41 Introduction
01:28 UPPER MANUAL : organ tabs and polyphonic presets
04:13 Solo Synth
05:07 Debunking the Mystery
06:19 Drum Machine
08:26 Three Quick Improvisations
09:47 Lower Manual : organ tabs, solo synth routing and arpeggiator
11:18 Musical Interlude
12:42 Bonus Musical Interlude

"A fresh video entry in the category 'Rare as a unicorn on stilts' - this mystifying auto-accompaniment machine organ and synth from Italys' Godwin is the only one we've ever encountered.

These type of sound generators were controlled by foot pedals and electronic accordions, generally in the hands of one-man-bands providing light entertainment in places where people congregated, imbibed alcoholic liquids and sometimes even got up and danced.
Remember those?
Ski resorts, beach clubs, dance halls, restaurants and hotels, for drinks or dinner.

The CD2 (we're not sure what the abbreviation actually stands for but we're guessing Computer Drums) is actually more than sequenced bass lines and chords though.
It's equipped with 2 separate preset- and organ sections and even a monophonic preset synth and the whole Shebang, unlike on many keyboards at the time, can be engaged simultaneously for massively wide and deep soundscapes.
All those sounds need lots of circuitry safely housed in a military grade flight case.
The GODWIN CD2 is well chunky, clocking in at a whopping 24 kilos.

The video explains most its specifications and includes a bit of history too but a summarisation would go something like this :

1. Sample Based Drum Machine with 16 Rhythms and 16 Drum Fills
2. Auto-Comp section with bass, chords and arpeggiator with 2 sounds
3. 2 x Organ Sections with 15 tabs total
4. 7 Polyphonic Preset Sounds
5. 7 Monophonic Synth Sounds
6. Various Chorus and Reverb Effects

Dreadbox Typhon - monophonic analog synthesizer with effects

video upload by Alfonse

"Music: "Python" (C) Copyright 2026 Alfonse Download the track here:



All sounds were generated by the Dreadbox Typhon, a monophonic analogue synth with 2 oscillators and stereo digital effects. There are conveniently sized knobs for a bunch of the key analogue parameters, including filter cutoff and resonance, and a central knob that allows you to morph between different waveform variations. Other parameters, including the effects, are adjustable using sliders on the right of the box.

Elektron Monomachine Emulation | Factory Patterns Demo

video upload by Autodafe

Part 1 here

"What if you could run an Elektron Monomachine inside your computer? 👀

In this video I’m testing Gearmulator MM, an emulation of the legendary Elektron Monomachine developed by Joe Landers as a fork of the Gearmulator project.

No talking — just the interface, some factory patterns and the sound of the emulation in action. 🎧

⚙️ Gearmulator uses low-level hardware emulation to run the original firmware rather than simply recreating the synth behaviour.

Joe Landers’ gearmulator-md-mm fork adds support for Elektron Monomachine and Machinedrum.
