You can transpose in Ableton Live. The transpose effect is in the Midi Effects section, called Pitch. It gives you octave presets but you can change that to single steps in the effect.
Another option is to do this:
- Create a midi channel with midi transpose within an instrument rack.
- Use chain selector to create chains with all the transposition steps you would want to use. (We suggest you make from -7 til +7)
- Create dummy clips with different chains selected on each of them.
- Use them as presets, simply drag it in parallel with your other instrument dummy clips (presets).
