I’ve followed the posts (thanks to you guys for the pointers) using Max for Live and it is working.
A lighter version (without Ableton/Max) should be doable as well. As long as a delay is inserted between setting the slice CC and playing the chromatic note, this seems to work fine (~20ms).
Here’s the Max device for Ableton 9:

(v0.2 interface change and overhaul)
INSTRUCTIONS:
IN ABLETON:
Drop this onto a MIDI track in Ableton.
Make the IO (ins/outs) visible on the mixer.
Select your MIDI controller as the Ableton track’s In.
Set the MIDI out to wherever the OT is plugged in.
Set the track’s MIDI out channel to your OT auto channel.
Highlight Monitor “In”
Highlight the Track Activator
ON OCTATRACK:
Turn on “Audio CC” under project>MIDI>control.
Select an OT track with a sliced and linear locked sample on it.
You can be in play, stopped, paused, grid, or live record mode, and any trigger mode.
USAGE:
On your MIDI controller note 36 should play slice 1 of the active track.
Change it with the “Basenote” parameter. Slices are now on consecutive notes.
Slicemode can be deactivated to use regular OT MIDI.
Increase the “Delay” parameter if notes ever play the wrong slices.
