About

MICRORACK is the most accessible modular synthesizer placed right on the breadboard. It is offering an impressive sound variability while being affordable and easy to learn.

MICRORACK is super portable. Its compact design, DC and USB-C power compatibility mean you can easily pack it in a bag and take it anywhere. Use a power bank to enjoy modular synthesis on the go - it's like having a portable rave!.

MICRORACK - The Most Portable Modular Synthesizer

We want to make modular synthesis accessible and not expensive, while promoting education in sound and electronics. Our goal is to lower the learning curve of synthesis for newcomers by providing tutorials and step-by-step guides.

To further expand MICRORACK within the community, we plan to open-source our platform and modules shortly after our crowdfunding campaign.

FAQ

MICRORACK is the most accessible and compact modular synthesizer system. It features affordable preassembled modules that are placed on a standard breadboard and patched with small wires.

MICRORACK is easy to learn step by step and it's designed for everyone from beginners to experienced musicians, synthesizer and electronics enthusiasts.

Our Kickstarter campaign ended successfuly in September 2024, raising over $85,000 in just 1.5 months, and currently we are in the production phase and expect to ship the first orders in mid-2025.

Here’s the small timeline:

  • Kickstarter Rewards: Shipping July – August 2025
  • Pre-Order Products: Shipping August – September 2025
  • In-Stock Products: Processed and shipped within 3–5 business days once available

MICRORACK has an intuitive "building-blocks" concept, making it easy to start creating even if you're new to synthesizers at all.

Each module represents separate function and concept, enabling easy, step-by-step learning experience.

We designed MICRORACK to be simple and all Kits include nice assortment of modules to try different synthesis and sound-design techniques right away.

After our production phase is complete, we will prepare a series of interactive tutorials with guides both for beginners and advanced users.

Yes! With a lot! MICRORACK has MIDI support and can be combined with everything via Audio Signal I/O or bare Control Voltage (CV). You can use it with headphones, speakers, microphones, guitars, instruments, other synths, your laptop and more,

MICRORACK out of the box features include:

  • separate 3.5mm/6.3mm Jack input and output modules with volume control
  • MIDI-CV conversion via esp32 module, with CC, Note, and Clock support,
  • Eurorack compatibility with Rack Chassis and 3.5mm Jacket power adapters (sold separately),
  • AE Modular compatibility with AE Chassis created (in joint development with Tangible Waves),

and more to come!

Ah, yes! We are very excited to work with talented individuals and companies in the synth community. Here are just some of them:

  • Moritz Klein: collaborated with us on VCF module design and planning to create more modules together

  • Tangible Waves: developed AE Modular MICRORACK Chassis, for full compatibility with AE Modular modules

  • Zvukofor Sound Labs: Created set of incredible Compressor, EQ, and Saturator modules and working on more

  • @decaprox from Keen Association: brought amazing Low Pass Gate module straight from Buchla world to MICRORACK

  • Community Modules: Modules Voted by the Forum Community as a stretch goal achievement

  • Secret Future Collabs: Stay tuned for more info this year!

All MICRORACK modules are analog, with a few exceptions like PT-chip based digital delay and counter chip in the sequencer.

We also offer separate digital ESP32-based Arduino-compatible module for advanced features like MIDI-CV conversion, oscilloscope functionality, and much more in the future.

  • Ultra-portable: Even huge setups fit in a bag, and it works with even simple 5V Type C power banks

  • Affordable: Complete Kits starting at $159, with modules starting at $9 (is that even possible?)

  • Connect Anything: From microphones, guitars and other synths to bare voltage, sensors or even wi-fi and far beyond

  • Open & hackable: MICRORACK Platform is open-sourced while schematics is published under CC4.0 license

  • Educational and Fun: Designed for step by step learning MICRORACK suprizes with variability of sound available even with small setups. Tutorials and guides coming soon too!

  • Community-driven: Ideas and feedback from engineers, modules voted by the community, shared experience from musicians and artists on forum and social media

  • Collaborative: Working on modules and accessories with synth enthusiasts and companies worldwide

Right from the start MICRORACK platform has 20 different modules including:

  • Sound sources: VCO, LFO, Blue/Pink Noise Generators

  • Sound shapers: Filters, VCA, Low Pass Gate

  • Modulation: Envelope Generator, 4-Step Sequencer

  • Effects: Delay, Distortion, Compressor, Equalizer

  • Utilities: Mixers, Clock Counter, Track/Sample & Hold

  • I/O: Various Input and Output Jacks, MIDI-CV (ESP32), Stylus Keyboard

and more

Absolutely! We encourage DIY module creation. Our platform is open-sourced, and with our DIY Kit you can start prototyping your own modules right on the breadboard alongside MICRORACK ones.

We're also offering engineers worldwide the opportunity to create collaborative modules together, with our guidance on design and joint production and distribution.

We already collaborate with few engineers from companies like Tangible Waves, Moritz Klein Instruments, Zvukofor and others. So feel free join by reaching us at collab@microrack.org.

Single module is sold as cheap as $9 while average module price is about $20, depending on complexety and price of specific components in it. But we are offering several kinds of Kits as well:

  • $159 - Synth Starter Kit: powerfull classic modular set with a little bit extra;
  • $159 - Pedal Starter Kit: works best as an fx pedal for instruments and vocals;
  • $299 - Explorer Kit: for deeper exploring the broad world of modular synthesis;
  • $599 - Full Kit Kit: basically everything we have, few modules twice or thrice;
  • $119 - DIY Starter Kit: minimalistic kit for hackers and electronics enthusiasts.

We plan to grow our assortment and have both for new modules and kits. So stay tuned!
