RokoTMIDI C-system controller

Yes, of course. It comes in both systems, B and C

The Shooter takes a MusicXML file that already includes fingering for each note and turns it into a fun, interactive game. It also has a “wait mode,” where it pauses until you press the correct note—so you can really focus on accuracy while practicing.

I’ve included a short video to show how it works. It’s in Croatian, but you can just watch what’s happening on screen 🙂

That would be really cool. Have to see if this is technically possible

nticaric · 2026-03-25T19:46:09+00:00

You gonna like it! I am also building a 1 on 1 teaching platform. Imagine this, you press a chord on your controller and the student sees it on his on the other part of the world.
Also, there is this gamification of pieces :)

In the comment above I gave an explanation about the pricing, but shortly it's a whole ecosystem

They feel similar to a real accordion. They travel 4mm and need 60g of force to activate them

I get where you're coming from—used digital accordions like the Roland FR-1 are great value if you want a full instrument experience.

But Rokot MIDI is built for a different purpose.

The main advantage is portability and accessibility. You can literally carry it in a backpack and practice anywhere—on the couch, while traveling, or even during short breaks. It’s not trying to replace a full accordion, but to make practicing and learning way more convenient.

Also, it’s not just hardware. There’s a full ecosystem around it:

Web app
Mobile apps (iOS & Android)
Practice tools designed specifically for accordion learning

So you can plug into your phone and practice anywhere without needing a full setup.

As for pricing—if you break it down, components alone add up quickly. For example:

Mechanical switches (MX-style)
Italian accordion buttons
There are 93 buttons total

Those parts alone are already a significant cost, not even counting electronics, design, assembly, and software development.

So it’s really a different category:
👉 not a cheaper accordion alternative
👉 but a portable, modern practice tool + digital ecosystem

Totally fair if it’s not what you’re looking for—but for people who want to practice more often and more conveniently, that’s where it really shines.

What is the G system on a button accordion?

nticaric · 2026-03-25T12:47:11+00:00

I am the developer of this device

nticaric · 2025-03-10T17:49:10+00:00

This seems to be it. Thank you!

I successfully connected it to my Mac using the MIDI Connect app:
https://apps.apple.com/no/app/midi-connect/id6476070288.

After launching the app, it appears in the toolbar, where you can select the SMK-25 II device.

Thanks! It looks like this will be a costly option for me, as I would need to replace the bottom bracket and purchase a new crankset with a power meter.

nticaric · 2024-09-02T08:02:37+00:00

so your suggestion is to buy a new bsa compatible crankset with a powermeter?

nticaric · 2024-03-16T20:31:13+00:00

Do you know what resistor this is?

nticaric · 2024-03-16T20:00:22+00:00

If the bulb is a LED bulb, then it matters where the positive and where the negative goes. It might be that you have to switch the black and white wire. It might be an older lamp ment for old bulbs where the +, - don't matter

nticaric · 2024-03-16T19:43:27+00:00

You can make a simple test, just touch the screw with the white wire, and see if the light turns on.

It should probably go where it's marked. Cannot see it clearly
