Connecting MIDI Devices
The EP-40 can connect via 3.5mm TRS-MIDI or USB-C. Both send and receive MIDI, so you can control external synths or use a keyboard to play the EP-40.
Physical Connection
Use a 3.5mm TRS-MIDI cable (Type A pinout) for hardware MIDI devices. The MIDI jacks are opto-coupled on input and output 3.3V. Connect MIDI keyboards, drum machines, or synths this way.
For USB-C, plug directly into a computer or USB MIDI controller. The EP-40 appears as a MIDI device and sends clock and transport messages.
MIDI Settings
Press SHIFT + ERASE to access system settings, then use minus/plus to navigate:
- 100: Clock off (default)
- 101: Clock in (receive clock from another device)
- 102: Clock out (send clock to another device)
- 110: Receive all channels, send on channel 1 (default)
- 111-126: Set specific MIDI channels 1-16
- 127: Send only if channel assigned to sound
- 130: MIDI thru off
- 131: MIDI thru on
- 140: Ignore program change (default)
- 141: Program change changes sound
Playing from a MIDI Keyboard
Connect your keyboard, then press KEYS on the EP-40 to enter chromatic mode. The selected pad becomes the root note. Hold KEYS + minus/plus to change octaves.
