Midicake UNA hardware composer in low atmospheric light

ONE IDEA CHANGED EVERYTHING

Parametric, Deterministic, Hands-On

We believe music should come from decisions, not chance: a pattern is only yours if you can repeat it.

So our instruments compute every note from your choices alone — all the complexity of a generative system, none of the chaos.

Find something you love, and it's there every time you press play.

“Novel Musical Instruments to inspire new music!”

Musical Complexity Made Simple

Effortless Composition

Our goal is to empower performers and producers with tools to add complex, repeatable layers to compositions in real-time, and without programming. We designed a MIDI sequence engine that synchronises with other sequencers and tracks with changes as a performance evolves.

  • Parametric

    A parametric approach to music making — 40 real-time parameters you can adjust on the fly.

  • Deterministic

    Deterministic systems that enforce repeatability — evolving, but never lost.

  • Intuitive

    A UI that inspires touch and experimentation, on stage and in the studio.

  • Flexible

    Flexible design for continued development and added value — free firmware, forever.

What players are saying

  • An instrument that inspires new music

    It hits a rare balance of creativity, build quality, and long-term support. It's not simply a clever gadget; it's an instrument that inspires new music!

    Solid piece of gear

    It's not just an arpeggiator, I would describe it as more of an interactive, generative sequencer. It's intuitive to use right from the start, but the deeper you go into the parameters and modulations, the more complex and unique the results are. The real craftsmanship of electronic instrument making is still being practiced here.

  • ARP oozes quality and capability!

    From the moment you take it out of the box, the ARP oozes quality and capability. But what makes this little box so impressive is how frequently it evolves!

    It feels like it was made for me

    The workflow, the build quality, the musicality — everything clicks in a way no other device has. The ARP is on a completely different level. It's simple, powerful, inspiring, and incredibly well thought out. Thank you for creating such a unique instrument.

  • Takes you places you'd never reach!

    A unique approach to generating layered arpeggios, chords and drones. Arp's intricate patterns can take you places you'd never reach otherwise!

    Arpeggiation redefined

    I like arpeggiation. But most systems do the typical up, down, up and down, down and up on typical scales like major, minor, 7 etc. I use arpeggiation in the context of alternative music, which is mostly guitar based. It contains exotic chords, dissonance, chromatics etc. So I was watching the YouTube video about new scales in the Midicake ARP and I was instantly amazed about the outstanding capabilities of the system. I bought it and was not disappointed!

    It's an Arpeggiator Jim, but not as we know it.

    I have been interested in procedural, polymetric and polyrhythmic composition for over 50 years and I have come across some very useful tools over the years. Midicake is now one of them.

    Top quality

    The Midicake has excellent build quality along with its packaging and overall presentation. Early days of use so far but it's quite intriguing with a few surprises. I've only managed to handle the basics so far but as you dive in further you start to see its broad potential. Very pleased with my purchase.

    Midicake quality

    I purchased the black cover in addition to the white cover I have for ARP. It is amazing quality as you'd expect from Midicake and fits like a glove. Amazing service and communication throughout the transaction. The best company I've ever dealt with bar none!
