How to connect the EP-133 K.O. II to Ableton
The K.O. II connects to Ableton Live over USB-C as a class-compliant MIDI device. Once the ports are on, you can send notes both ways and sync transport and clock in either direction. Here is the full setup.
What you need
- A USB-C cable (5V, 1A or better).
- Ableton Live with its MIDI ports enabled.
The K.O. II is class-compliant, so there are no drivers to install.
Enable the MIDI ports in Ableton
- 1
Connect the K.O. II to your computer with a USB-C cable.
- 2
In Ableton, open Preferences then MIDI.
- 3
Find the EP-133 in the ports list and turn on Track and Sync for Input and Output as needed.
Sync the clock
Pick which device is the master:
- Ableton as master: in Ableton enable Sync Output for the EP-133 port. On the K.O. II press SHIFT + ERASE, go to MIDI then Clock, and set it to in.
- K.O. II as master: set its MIDI Clock to out, then enable Sync Input for the EP-133 port in Ableton and set Ableton to follow external sync.
Match the MIDI channel
In the K.O. II system settings, go to MIDI then Channel to pick the channel it sends and receives on, and set your Ableton track to the same channel.
For audio, the K.O. II is not a USB audio interface. Take sound out of the 3.5mm output into your audio interface separately.
questions
Do I need to install drivers for Ableton?
No. The K.O. II is class-compliant USB MIDI, so Ableton sees it as soon as you enable the port in Preferences.
Why is the EP-133 not showing in Ableton's MIDI list?
Use a data-capable USB-C cable, connect directly instead of through a hub, then reopen Ableton's MIDI preferences.
How do I keep the EP-133 in time with Ableton?
Decide on one master clock. Either set the K.O. II clock to 'in' and send sync from Ableton, or set it to 'out' and have Ableton follow external sync.
Can I record the EP-133's audio into Ableton over USB?
Not directly, it is not a USB audio interface. Route its 3.5mm output into your audio interface and record that.
Can I play EP-133 sounds from an Ableton track?
Yes. Enable the output port, match the MIDI channel, and notes from your Ableton track trigger the pads.
