Storm Summoner — MIDI controller
From the floor to the desk
The most exciting instruments of this decade are being sold as pedals: stereo, programmable, and increasingly skipping stomp switches altogether.
Storm Summoner is how you play them.
01
No stomping required.
Storm Summoner is a touch-based MIDI controller purpose-built for effects pedals.
Perfect looper timing, every time. Queue a parameter change at the bridge, when both hands are going to be busy. Add motion with LFOs, tilt and proximity sensors.
Total control, at your fingertips.
02
Controlled by electricity.
The touch wheel and buttons are just half of the story.
- Capacitive interface: Sweep the wheel, tap the buttons — and remap all of it, scene by scene, 128 times over.
- Modulation heaven: 2 LFOs, S+H, X/Y tilt. Wave your hand to open a filter or flash a light to duck compression.
- Sixth sense: A sensor detects proximity and ambient light. Assign either to any parameter.
- Master time: Generate BPM internally, tap it in, sync from MIDI or patch to your analog sequencer.
- Flexible integration: Route an expression pedal to CC, pass MIDI from a DAW, even translate CV.
03
Violate the spec.
¼" TRS MIDI is Officially Not A Thing, yet that's exactly what most pedals expect. That's why the primary TRS MIDI OUT jack on Storm Summoner is 6.35mm aka ¼".
Sorry, not sorry.
We put ¼" to ⅛" and ⅛" to 5-pin DIN adapters in the box, too. Just in case.
- Polarity, handled: Type A, Type B, even TS: the pedal database knows how every pedal is wired and configures the jack to match. No "MIDI box" required.
- More than a CC list: The database knows whether a parameter sweeps 0–127, snaps between named values, or fires one-shot actions — even when a pedal reuses a CC for different jobs depending on its mode.
- Sequenced effects: 40+ assignable actions allow beat-sync’d looping, parameter morphing, randomization and more.
- Obsessively current: New pedals often land in the database the day they’re announced.
- Universal mounting: Tripod thread allows setup anywhere: mic stands, drum kits or mixing desks.
04
Arrive prepared for anything.
- In the box: Storm Summoner, ¼" to ⅛" TRS adapter, ⅛" to 5-pin DIN adapter, silicone anti-slip sticker, tripod-to-mic-stand adapter, optimism.
- Protect ya neck: A sturdy custom-molded hard shell travel case comes standard.
- Reliable power: Center-negative 9V barrel or galvanically isolated USB — laptop power without laptop hum.
- No smartphone apps: Browser-based configuration and drag-and-drop firmware updates over WebUSB.
- Open source: MIT-licensed firmware. Inspect it, fork it, or improve it on GitHub.
- Go wireless: Connect a Sky Bridge and control your pedals wirelessly. Sky Bridge can provide power to Storm Summoner as well.
Open by design
The firmware is yours.
Storm Summoner's firmware is built in public and licensed under MIT. Inspect it, fork it, fix it, or teach your instrument something new. There is no black box between you and the hardware you own.
The pedal database is open too. Device definitions live in their own repository, so support for new pedals can grow without waiting for a firmware release.

Questions
Frequently asked.
Will my pedals work with Storm Summoner?
If your pedal speaks MIDI, yes. The pedal database knows how each pedal is wired, so TRS Type A/B polarity is handled for you, and the box includes adapters for ⅛-inch TRS, 5-pin DIN, and a tripod-to-mic-stand mount. The database covers the major MIDI-enabled pedals, so the manual can stay in the drawer where it belongs.
What if my pedal isn't in the database yet?
The database is updated frequently, and you can always map any MIDI-enabled pedal manually in the meantime. If you'd like a pedal added, send us its manual or CC table. And if you make pedals: we'd love to have yours supported on your launch day — see for pedal brands.
Does Storm Summoner make sound on its own?
No — and that's the point. It's a controller: it makes the gear you already own do more. Sweep a filter with a finger, morph two parameters at once, switch your whole rig between songs. The tutorial videos above show what that looks like in practice.
When will mine ship?
Storm Summoner is made to order. Every enclosure is cut, finished and assembled by hand in Toronto, and units ship in the exact order they were purchased. When the queue is short, that means days; after a busy stretch, it can mean a few weeks. You'll get a tracking number the moment yours leaves the bench.
How do firmware updates work?
Open the configuration tool in any Chromium browser (Chrome, Edge, Brave, Arc), connect via USB, and the firmware updates over WebUSB in under a minute. No mobile apps. No subscriptions. The firmware is open source on GitHub.
Do you ship internationally?
Yes. Orders leave Toronto via Canada Post. For the full story — carriers I will and will not use, and why US shipping includes an extra 10% — see the shipping FAQ.
Made in Toronto. Sent everywhere.
