Connecting an electronic drum kit over USB-C
Updated 24 July 2026
Use a USB-B to USB-C data cable straight from the module to the device. Most drum modules have a square USB-B “TO HOST” socket; newer ones have USB-C, in which case use a USB-C to USB-C data cable.
The cable must carry data. A charge-only cable fits perfectly and passes no MIDI — it is the most common cause of a kit that silently never appears.
The fix, step by step
- Find the module’s USB port. On most kits it is a square USB-B socket labelled “TO HOST” or “USB COMPUTER”.
- Connect a USB-B to USB-C data cable to your Mac, USB-C iPad, or iPhone 15 and later. If the module has USB-C, use a USB-C to USB-C data cable instead.
- Power the module on and open iQuantize. It is recognized automatically.
- If nothing appears, swap the cable for one you know carries data, then try a powered USB hub between the device and the module.
The iPad has one port — what about headphones?
A USB-C iPad has a single port, and you need it for the module. Use a powered USB-C hub with both your wired headphones and the module connected, or monitor through the drum module’s own headphone output while the app plays the chart through the iPad speaker.
Do not solve this with Bluetooth headphones. They add enough delay to make tight playing impossible — see fixing latency.
Practice with feedback that tells you what to fix
iQuantize scores every take against the chart, names what slipped, and picks the next groove for your level.

Common questions
How do I tell a data cable from a charge-only cable?
You usually cannot, by looking. The reliable test is to try a cable you know works for data — the one that came with the module, or one you have used to move files. Cables bundled with power banks and chargers are frequently charge-only.
Do I need a driver?
No. Drum modules are class-compliant USB-MIDI devices. macOS, iOS and iPadOS recognize them with no driver and no pairing step.
Does a USB hub add latency?
Not meaningfully. MIDI messages are tiny and a hub adds far less delay than any wireless audio path. Monitoring latency comes from your audio output, not the MIDI cable.
