Indtroducing AcidBoxMynah
video upload by MoShang
"AcidBoxMynah is an alternative firmware that turns the Mynah into an acid groovebox. Based on the open source AcidBox project for ESP32. It provides an acid combo of tb303 + tb303 + tr808 like synths. Filter cutoff, reso, env mod, accent, wavefolder, overdrive within each 303, per-instrument tunings, hi-pass/lo-pass filter and bitcrusher in drums, send to reverb, delay and master compression
While the original project is headless, the AcidBoxMynah fork provides direct control with the Mynah hardware and adds a number of additional features detailed in the user Manual below. Like the original firmware, the AcidBoxMynah is open source and made available under the MIT license.
More info at https://groovesizer.com/"
Update: press release follows:
"Hot on the heels of Mynah's launch this past May, Groovesizer has released AcidBoxMynah - a free, open-source alternative firmware that transforms the ESP32-S3-based sampler into a dedicated acid groovebox.
Built on copych's open-source AcidBox project, AcidBoxMynah takes what was originally a headless engine and gives it a full physical UI on Mynah hardware - 24 tactile switches, an 8×2 NeoPixel grid, OLED display, and a single pot for hands-on parameter control. Under the hood, it's a combo of two TB-303-style synths plus a TR-808-style drum machine, with filter cutoff, resonance, envelope mod, accent, wavefolder and overdrive per synth voice, plus hi-pass/lo-pass filtering and bitcrushing on the drums, all routed through send effects and master compression.
The Mynah fork adds a 16-step sequencer with per-step note, accent and slide editing, 16-lane synth and 8-lane drum automation, scale quantization, swing, and manual Sequencer Mode in addition to the original's autonomous Jukebox Mode. Quality-of-life additions include runtime drum kit browsing, per-voice muting, and pot-lock to prevent accidental parameter jumps.
Like the original AcidBox, it's fully open source under MIT license.
Switching is effortless. Owners can flash AcidBoxMynah straight from the Mynah web app's firmware tab and swap back to standard Mynah firmware anytime - AcidBoxMynah keeps its own folder on the SD card, so nothing overwrites or conflicts with existing samples and patterns.
AcidBoxMynah is available now at groovesizer.com/acidbox-mynah."

FAT Freebass FB383 analogue synth tutorial, review, sound demos: is this a good Roland TB-303 clone?
video upload by ako
"I've been really liking the FAT Freebass FB383 analogue TB303 clone again (even if staying in tune is more of an aspiration than guarantee with this thing). It’s fully analogue and the filter does all the good self oscillating squelchy things you want from a 303 even if it does lack a sequencer (slides and accents can be triggered with MIDI). Some sources claim it's a fairly faithful clone of a TB-303, not sure how valid that is though. For those outside the UK wondering, this synth is just a MAM MB33 with a different paint job. You can also feed audio into this synth and use it as a MIDI triggered enveloped / gated filter, which is kinda cool! Had this set up recently for some acid parts (ofc) and it’s been fun using this synth again so I thought I'd make a video on it - hope you enjoy :)
Chapters:
00:00 - review, background info and basic features (incl. how it differs from a "real" 303 and other clones)
07:58 - Programming sounds (pt1. VCO and tuning)
10:20 - Programming sounds (pt2. filter and envelope)
12:24 - Programming sounds (pt3. Accent and slide)
15:47 - Programming sounds (pt4. Using the filter's external audio input)
21:07 - Sound demo 1 - the synth in a track with no effects on it
23:02 - Sound demo 2 - the synth used in a track through an overdrive pedal
Sound demo 2 is a verison of my 'MYST.wave II Unfinale':

AMYboard - the $29 DIY modular synth running Python.
video upload by Brian Whitman
via Brian Whitman of AMYboard
"Today, we’re launching a new music hardware platform! Meet the AMYboard, a 10HP modular-sized synthesizer brimming with inputs and outputs for digital and analog audio, MIDI, and two CV channels.
The AMYboard firmware runs Micropython, and can be controlled and programmed over the web, where you can share your own creations with others. You can also use AMYboard in Arduino to create music devices of your own design. It’s only US$29.90 - a very inexpensive way to get started making your own modular-capable synths. It can be powered over USB or a 10-pin modular power cable, and comes with a 10HP laser-cut faceplate. You can buy one today!
AMYboard is powered by AMY, the synthesis and effects toolkit that DAn Ellis and I have been working on for the past few years. AMY is a beautiful-sounding, efficient re-creation of classic analog synths – like the Juno-6 – and FM synths – like the DX-7. It can also act as a sampler, play WAV files, or let you make your own synthesizer setups in code from bare oscillators, effects, and filters. AMY is open-source and runs on all sorts of hardware. It already powers some neat synths like the Diapasonix, the Spark, and our own Tulip Creative Computer. AMYboard is our “reference hardware” for AMY - running the same ESP32-S3 as Tulip with 8MB of RAM, but with new features including both analog and S/PDIF (digital) audio input and output, enabling live effects, sampling, and filters. We’ve also added an SD card for sample storage, and an I2C host port for connecting your own displays and knobs!"
AMYboard launches with AMYboard online – a web based simulator and control surface for the AMYboard. You can experience AMYboard online before even buying an AMYboard. AMYboard online runs the same core engine as the AMYboard hardware (ported to WebAssembly) so you can set up and interact with the synthesizer over the web. When you’re ready, you plug in your AMYboard, download your patch, or control it in real time over the web, including the capability to edit and store code on your hardware that will boot up the next time you turn it on. AMYboard’s default firmware allows anyone to code their synth creations in MicroPython running on the hardware; the AMY synthesis engine itself runs in bare-metal C, but you can load your own “sketches” onto the board to build complex environments. For example, here’s a generative house track with a Derrick May custom “WOODPIANO” FM patch. Or here’s a TB303 + 808 acid setup. Or add a filter and reverb to a DX7 patch. AMYboard online also comes with AMYboard World, an online community for AMYboard users to share sketches with each other. We’re really excited to see your cool creations, please do share them!

TB303 Day. Acid house with Kaleidoscope
video upload by Vadjuse
"Patch notes.
Track 1 is a classic acid bass. A saw with an opening filter. And a bit of glide.
Track 2 is a kick drum—a triangle wave with pitch modulation.
This is where the magic begins.
The bass volume envelope on Track 1 modulates the decay of the kick drum on Track 2. The louder the bass, the faster the kick drum rolls in.
The kick drum volume envelope (which the bass modulates, don't forget) on Track 2 modulates the modulation depth of the volume envelope, which modulates the opening of Track 1's filter. This is what makes the bass sound so unique.
You won't be able to get this sound on a TB303 or other high-end grooveboxes. Because their modulations can only exist within a track and don't extend beyond it. In this video, the sounds of both instruments are closely linked and influence each other.

EMS Universal Sequencer Playlist
video uploads by analogia pl
A few of these have been featured on the site before. You can use the player controls to skip around.
Playlist:
1. EMS Synthi with Universal Sequencer and RSF Kobol #emssynthi #rsfkobol #rolandph830
It’s a tune done on the Synthi and EMS Universal Sequencer with some help from RSF Kobol processed by Roland PH-830 phaser.2. 2 x EMS Universal Sequencer with Roland MC-202 #emssynthi #emsuniversalsequencer #mc202
Universal Sequencer is playing a sequence on the Synthi and the 202 - that’s why it’s called “universal” as both sequence and real time layers have CV/gate outputs. No effects other than spring reverb on the Synthi.

This video shows some of the updates.
The updates include:
new mapped_pot_controller to allow the pots to have different modes
sequencer has separate lane for slides so that accent & slide can happen on same step
tbish_synth now has 4 different waveforms to choose from
can edit the sequence steps, both notes and accents/slides/mutes
can switch between sequences
can adjust bpm & steps_per_beat
actually using the LEDs

Voodoo Ray/A Guy Called Gerald - Novation Circuit version
video upload by Guinan
"Time for the first British acid house hit and another Hacienda favourite. The Manchester act A Guy Called Gerald blew up the Manchester music scene with his 808 and 303 tour-de-force. He's still making excellent music @AGuyCalledGeraldTV #voodooray
Everything you hear was programmed into the Novation Circuit and played ‘live’ straight out of the headphone jack into my phone. No extra effects or outboard gear are used during playback.
The @IsotonikStudios sound pack RB 303 by Yves Big City got me thinking about how capable the Novation Circuit could be for a blast of acid house. I hope this attempt gets close to the flavour of the original. • DEMO - RB 303 - Novation Circuit Pack by Y... [posted here]
@GyuBeats has done some great video breakdowns of the track and is obviously a fan. Big thanks as he helped me track down some of the original samples. • Why Does VOODOO RAY Still Sound Fresh Today?
I also found the following website which is a fantastic resource of patterns for 303-soundalikes. It just had to be called Acid Tabs….. https://acid-tabs.com/303_patterns.ph...
I hope you like the track – drop a comment if there is an 80’s or 90’s track you’d like to see a version of.
Synth nerd details;
The 808 sounds are a mix of samples from Isotonik and a pack that is sometimes free called 808 From Mars.
The vocal samples are from a surprising source of an old comedy routine from Peter Cook and Dudley Moore. The ‘voodoo ray’ sample is actually cut from a snatch of Peter Cook saying 'voodoo rage'.
A key part of the track is the excellent singing of Nicola Collier. I didn’t have a singer to hand and I wasn’t going to impose my dulcet tones on the world. The ‘singing’ is therefore played on the Arturia plug-in ‘Augmented Voices’.
I hope it fills the gap for now and doesn’t detract from the overall track.
All samples are edited and positioned on drum pads then sequenced/played on the Drum 4 track of the circuit."
Voodoo Ray/A Guy Called Gerald (Circuit Tracks & Rolands Version )
video upload by Guinan
"'Say Hello To My Little Friends'…..
Something a little different again. This is a reworking of one of my earlier videos but with an 'acidic' twist. At the time there were comments wondering how it would sound with Roland synths rather than my attempts at recreating the sound using the internal synth engine.
I couldn’t resist the challenge, so the Circuit Tracks has some company in the form of a Roland T-8 and S-1 Aira. The T-8 is a drum machine based on a selection of classic Roland sounds, but it has the added bonus of a very good TB303 emulation.
The Roland S-1 on the other hand is a 4-voice recreation of the classic 80’s synth, the SH-101. An awesome synth in it's own right it's a great partner for the Tracks to use with one of the external MIDI tracks.
Both of these Roland originals were an essential part of the classic Acid House sound and the track, ‘Voodoo Ray’ so this seemed a natural Circuit Tracks project to rework. I’ll keep a separate playlist of any tracks with external gear to keep my main playlist Tracks only.
For this video I’ve copied the patterns across to the Midi 1 & 2 tracks, hooked up both of the Roland individually to the MIDI Out and Thru (setup in Advanced Setup to be individual MIDI Outs). Each of the Roland boxes are then fed into each of the Audio Inputs so they can be panned, level altered and have effects applied individually. Each of the Roland boxes are not using their own sequencers but are just being used as slave MIDI synths playing the patterns sent via MIDI from the Circuit Tracks. T-8 bass was set to MIDI Ch3 and S-1 to Ch4 to match the default channels for these tracks."

Live Synth Techno in the Studio: Squarp Hapax, TB-303, Jupiter-80
video upload by MR TUNA Music
"Some more uncharted territory here with some techno beats live from the studio. Not really our regular vibe but very fun and fast. Jupiter-80 creating some qualiy keys and big bass from the Korg Prologue with the boiling acid of the TB303 pushing us up and up and UP in the background.
Is this actually techno or is it something else? I can never actually nail it down properly this is probably too 'progressive'."

Bad Gear - The Original Boutique
video upload by AudioPilz
"Welcome to Bad Gear, the show about the world’s most-hated audio tools. Roland is inarguably the greatest synth brand in history but even die-hard fans like me have a hard time dealing with the miniscule displays, buzz-killing menu diving and product philosophies that seem like they were conceived after a 72h non-stop bender.
Today we are going to talk about the MC-202. This 80s analog synth and sequencer not only might as well be the secret lovechild of an SH101 and TB303, it also appears to be the root of all the aforementioned evil.
