Tempo Automation (accelerando and ritardando)

Instrument X
1

Hi, I’m new to the group here. I’m using Instrument X for a film score, and I have some tempo automation, not just immediate tempo changes written into the score. Instrument X can read the tempo map exported from Doricao for abrupt tempo changes, but it doesn’t read automated tempo changes (gradual over time, such as accelerando or ritardando).

I have also tried using Instrument X within Pro Tools via ARA. And again, Instrument X does not respond to tempo automation in Pro Tools.

Is this a limitation? Seems like a pretty big limitation. Much music outside of pop uses tempo fluctuations, and being able to use Instrument X only with static tempos or abrupt changes really diminishes its usefulness with orchestral Instruments.

I thought this was considered, but I can’t find the right solution. Can anyone confirm?

I can say the ARA bridge in Cubase works just fine regarding tempo changes.

Thanks for the response! Tempo changes, as in gradual changes? Not just changing from 80 bpm to 120bpm from one br to another?

Yes. Ritard and Accelerando’s generated by Dorico work just fine.

Thanks for confirming! I found a glitch in Pro Tools.

I’m going to share the steps in case someone else has the same issue.

There was an icon in the transport that controls the conductor track. This track enables or disables Pro Tools from following the tempo map.

The conductor track is enabled by default. I disabled the conductor icon, hit play, stopped playback, and then re-enabled the conductor track. Now, when I hit play, Instrument X follows the Pro Tools tempo track.
