DIY Lo-Fi FM Drum Machine with Arduino Nano on Breadboard - A Few Beats

video upload by Waiting For Zyo

"Another DIY instrument! This time I used a famous microcontroller: an Arduino Nano (compatible, tbh), a few buttons, and some code to made a really basic (lo-fi) FM drum machine with a built-in sequencer.

Here are some of its features:

• 4 instruments: kick, snare, hi-hat, and tom
• 4 main sound controls: tune, decay, FM amount, and FM ratio
• 4 secondary sound controls: balance, pitch envelope decay, pitch envelope range, and FM feedback
• A full 16-step sequencer with swing and basic parameter locks and on-grid rolls

At the moment, it only has a basic audio output, so I recorded everything into Ableton and added a bit of filtering and some reverb.

These are four beats I made from scratch using only these basic parameters and the internal sequencer.

Enjoy!"

KONSTRUKT-8 is an expressive live performance instrument and sound design tool – plus a hands-on deep dive into electronic circuit design. Each of its eight DIY modules comes with a detailed build guide and can be explored on a breadboard first, letting you trace every circuit design decision before assembling the final instrument.

KONSTRUKT-8 includes four fully analog drum voices:

• Kick Drum. A resonant bridged-T network produces deep, punchy kicks.

• Snare Drum. A burst of filtered transistor noise layered over a tuned resonator creates a crisp snap.

• Hi-Hat. Six dissonant square-wave oscillators are mixed, filtered, and overdriven to create metallic percussion.

• FM Drum. Two interacting oscillators form a versatile percussion voice capable of kicks, toms, bells, and cymbal-like sounds.

A four-channel drum sequencer lets you tap in rhythms that loop automatically. Under the hood, shift registers store the pattern as a circular sequence of binary data.

All voices feed into a four-channel mixer with per-channel FX sends and a master insert, allowing you to shape the entire beat with external effects or the built-in distortion and compressor.

Two effects modules complete the system: an analog bucket-brigade delay (BBD) with flanger and delay modes, plus a diode-based compressor with sidechain capability.

WHAT’S INCLUDED

Both versions ship with:

• EDU DIY Kick Drum kit

• EDU DIY Snare Drum kit

• EDU DIY Hi-Hat kit

• EDU DIY FM Drum kit

• EDU DIY Drum Sequencer kit

• EDU DIY Output Mixer 2 kit

• EDU DIY BBD kit

• EDU DIY Compressor kit

• 8 downloadable build guides

The system version also includes:

• Eurorack enclosure with integrated power supply

• 15 braided patch cables (5× 20cm, 5× 30cm, 5× 60cm)

There's a very excellent detailed build and demo video from ‪@mr_floydst‬ here, • MT32-Pi DIY synthesizer: bare metal 80s no... [below]

Oddly the hardware worked out cheaper (despite a bigger display) as this is a commoner target build.

This excellent project uses any Pi from the Pi Zero 2W upwards to recreate a multi-timbral emulation of the Roland MT-32 synth and also act as a player for soundfonts in the .SF2 format.

X1L3 - ARMALYTE is ALLEYKAT - SID 8580 - DEV - 3 voice test - love action - scope render

video upload by X1L3

"More work on the SID module. Another 3 channel test.
Those chorus sections 🔥👌❤️

The meow song (love action) by the Human league....

The floor is lava..
Baba is you...
And Armalyte is Alleykat 🐱🐾🐾🐾

Project Armalyte is now called Alleykat. My long time feline companion, Maddie, passed away two weeks ago. She would sit and chill with me for hours while i coded and toiled away on this and other projects. She'd see me off when i went to work and be waiting for me when i got home. She'd ride around on my shoulder, sleep on my bed and follow me everywhere. From the scared and timid cat who had a massive alopecia bald patch on her back and who i think had had a bit of a bad life as the frightened girl who crept into my shed all those years ago, she became a gentle, funny and loving companion. She was 18, she was my friend for many years, and i miss her 😔

The module is now a tribute to kitty cat. And she'll be appearing on the back of it.

Nine lives - no regrets ❤️

Nice cover of the meow song for her. When the module is complete i'll come back and tweak it for a proper demo, where it will be paired up with the song 'tell me when', which also has a meow in towards the end 😂

Sounds somewhat like a Hubbard outing for the verses, but then you hit the chorus and it goes full sublime Galway - Ocean loader. It sounds wonderful. in a kept in the loft for 30 years way 😊

Tuning is still as crap as my Korg Monopoly on a good day. But a bit of pitch bend wheel keeps it sweet enough. The day i move it off the breadboard and get a precision reference in there for 1voct tracking can't come soon enough.

Currently waiting for some parts to make the next big leap. This is where the last few registers will become active and all the ringmod/sync/wave mixing kinds of things will come to life.

Than chorus though..
I fucking love this thing.....
The nostalgia feels are something else ❤️❤️❤️"

I got a BRAEDBOARD (not a typo) breadboard module for an AE modular synth a while ago. I've only just managed to install it. So I thought I'd try some example circuits out from the AE modular Wiki, just to see if it works ok, and also before I go onto something more complex.

00:00 Intro to the BRAEDBOARD.
01:19 Fitting the module into the synthesizer.
03:55 Building the CD40106 oscillator.
04:46 Trying out with the basic oscillator.
05:56 Adding a filter to it. Altering cutoff and resonance.
06:57 Sequencing the filter cutoff.

The Human Comparator 73-75 Serge Homebuilt w/ Custom Expander

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

via this listing

"This instrument is tons of fun, and also is a seriously customised build. I bought this kit years ago and have been slowly assembling it. It works in full, and unlike many specimen out there, is very compact while being equipped with a spring reverb tank. I recorded two albums on it in its unfinished state, then had it dust up for a bit, but now it's fully finished.

It received the following customisations:

A halfpanel expander (the black strip) has a DC offset generator, noise source, inverter and an output summator - 3.5mm mono output on the right side. This expander implements some functions that are not there or will save you an entire voltage processor half.
As a finishing touch, there's a fully powered breadboard for you to try out some stuff on. It has +-12v and ground broken out to it, so active circuitry is a possibility.
I built a custom linear power supply for it - its regulators are short-circuit protected, so the breadboard is somewhat foolproof.
There's a long ass bank of decoupling capacitors on the lower panel, ensuring smooth and quiet operation. So far it has been remarkably fine, and has greatly reduced the voltage processor bleedthrough that many people on the 73-75 group have experienced.
The reverb and preamp circuits have been replaced by entirely custom circuitry attached to the upper panel; the original ones were too noisy for my liking.
The jack color scheme is a standard Serge one instead of the THC-proposed faded old-styler colouring
The 3.5mm~banana converter banana jacks output ground if the 3.5mm part is not used, making them ground references.
Will ship more or less anywhere via Estonian standard post double-boxed and with tons of filler; other carriers = add'l cash. I will throw in some shorter banana cables, too. This unit runs on 15v AC (not DC!) - i can help figuring out a suitable brick for you to buy in place, as mine is european standard and my only one, so i'd like to keep it.

My camera is not of best quality, so a hi-res reference can be found on the kit producer's website (73-75.com) to see which exact modules are there."

"At Superbooth 2024, we met Leo from Microrack to talk about their new concept of modular synthesis in a compact format. These innovative modular synths aim to be the most accessible on the market, providing a powerful and musical sound for beginners and experienced users alike. The setup showcased at the event included three VCOs and a filter module, demonstrating the potential for creative sound manipulation and experimentation. Leo explained that the self-contained unit is portable and can be powered by a power bank, allowing users to create music on the go.

In addition to the modular synth setup, Microrack *also introduced *DIY modules that enable users to customize their own synth on a breadboard platform. The small jumper wires used for patching are flexible and durable, enhancing the user experience and offering a diverse range of creative possibilities. Leo highlighted the educational aspect of the project, emphasizing the importance of making modular synthesis accessible to users of all skill levels. The Microrack products are set to launch on Kickstarter in June, with the aim of providing educational materials alongside the hardware for a comprehensive user experience.
