MIDI I/O
The MIDI I/O menu in T1 Config is where you configure how the T1 sends and receives MIDI over both USB and TRS connections.
Use it to control:
- Note input and output
- Clock input and output
- Start / Stop input and output
- Program Change input and output
- TRS Thru port behavior
This makes it possible to adapt the T1 to different setups, whether you are working with a DAW, external sequencers, synths, or a larger live rig.
USB MIDI
The USB section lets you enable or disable MIDI input and output over USB for the following message types:
- Notes
- Clock
- Start / Stop
- Program Change
You can configure:
- what the T1 receives over USB
- what the T1 sends over USB
This is useful when connecting the T1 directly to a computer, DAW, or USB host.
Typical uses
- receive notes from a DAW or keyboard over USB
- send clock from the T1 to software
- receive Program Change messages from an external controller
- send Start / Stop to other software devices
TRS MIDI
The TRS section provides the same type of control for the physical MIDI TRS ports.
You can enable or disable:
- Notes
- Clock
- Start / Stop
- Program Change
separately for:
- TRS In
- TRS Out
This allows the T1 to fit into different hardware setups without sending or receiving unwanted MIDI data.
Typical uses
- receive clock from an external drum machine
- send notes to external synths
- send or receive transport messages
- pass Program Change messages through a hardware performance setup
TRS Thru Port Functionality
The Thru port functionality setting determines how the Thru port behaves.
Two modes are available:
- Thru
- Out 2
Thru
In Thru mode, the port behaves as a hardware MIDI thru connection:
- MIDI In → Thru
Use this when you want incoming MIDI to pass directly through the T1 to another device.
Out 2
In Out 2 mode, the Thru port becomes a second MIDI output:
- Out → Thru
This gives you an additional configurable MIDI output from the T1.
When Out 2 is active, you can configure its MIDI output behavior just like the main TRS output.
Program Change
The Program Change toggles in MIDI I/O control whether the T1:
- receives incoming Program Change messages
- sends outgoing Program Change messages
Use these settings together with the T1’s Program Change behavior if you want to:
- switch Banks or Patterns from an external device
- send matching Pattern or Bank changes to connected MIDI gear
Clock and Transport
The Clock and Start / Stop settings determine whether the T1 sends or receives timing and transport messages on each connection type.
Use these settings when deciding whether the T1 should:
- act as the master clock
- follow another device’s clock
- send transport messages to other gear
- respond to external transport control
For more detailed sync behavior, see Sync, MIDI Connectivity, Analog Sync, and Wi-Fi and Ableton Link.
Practical Examples
USB with a DAW
A common setup is:
- enable USB Notes In
- enable USB Clock In if the DAW is the master clock
- enable USB Start / Stop In if you want the T1 to follow DAW transport
- enable USB Program Change In if you want the DAW to switch Banks or Patterns
Hardware MIDI Setup
A common hardware setup is:
- enable TRS Notes Out to drive external synths
- enable TRS Clock Out if the T1 is the clock master
- enable TRS Start / Stop Out to control connected devices
- use Thru mode if you want incoming MIDI passed directly onward
Dual Output Routing
If you need more hardware outputs:
- set the Thru port to Out 2
- configure TRS Out and Out 2 separately
- use the two outputs to drive different external devices
Best Practices
- Only enable the MIDI message types you actually need
- Disable unused clock or transport connections to avoid conflicts
- Use Thru when you need direct hardware pass-through
- Use Out 2 when you need a second MIDI output from the T1
- Check Program Change input and output settings if external Pattern switching is not working as expected
