Geoff Fry Drum Lessons

Need e-drum owners to help verify MIDI mappings.‼️
As some of you know I am co-founder of Drumr iOS App.

We’re currently reviewing the MIDI mappings for all the electronic drum kit modules we support and I’m looking for a few volunteers to help verify that everything is working correctly in real-world use.

For anyone unfamiliar with Drumr, it’s a practice app that combines notation, play-alongs, video lessons and real-time timing analysis using MIDI input from electronic drum kits.

We’ve tested these internally, but I don’t physically own every module on this list, so I’d love some help from owners of the following kits:

Roland TD-1 / TD-1DMK
Roland TD-07
Roland TD-11
Roland TD-15
Roland TD-17
Roland TD-25
Roland TD-27

Yamaha DTX6 Series
Yamaha DTX700
Yamaha DTX900

Alesis Crimson II SE
Alesis Strike Pro / Strike Pro SE
Alesis Nitro Max
Alesis Surge / Command Mesh

2box DrumIt 5 MKII

EFNOTE 3 / 3X
EFNOTE 5 / 5X
EFNOTE 7 / 7X

To take part you’ll need:

• One of the modules above
• An iPhone or iPad running iOS 26 or later, or a Mac running macOS 14.4 or later
• A USB MIDI connection between the module and device

The test should take around 10–15 minutes.

Everyone who helps will receive a free 30-day Drumr subscription so you can access everything needed for testing.

If you’re interested, comment below with your module and device and I’ll get in touch.

Thanks for helping us make sure every supported kit works exactly as intended.

Thanks

Geoff Fry
