Tine

Start and stop playback

One word each. "Play" and "stop" run the transport in about a third of a second, without reaching for the space bar — useful when both hands are on an instrument and the keyboard isn't.

Say it like this

Each of these was run against a real Ableton session on every model below, and the reply is what Tine actually said — quoted, not rewritten. Switch tabs to see how the answer changes with the model.

These are a floor, not a syntax — you can be a good deal vaguer, and how vague scales with the model you run. The smaller local model wants a clear verb and a clear target; the hosted one takes the most roundabout phrasing you can throw at it.

Also in playing & recording

Tine does this in Ableton Live 12.3.6
