In the Arranger you could set up a pattern to play with another tempo (ie doubled, if there is room for it within the BPM range, max 300). But I guess that changes the tempo globally on all tracks in that pattern. Which might be a trouble or not, depending on your situation.

I don´t know how the result will/would be. But you could experiment with having an recorder buffer recording the output (of track or main/cue out), while the Arranger switches from a pattern with low BPM into another pattern with high BPM.

I honestly don´t know if the recorder (and thus also the recording) will be fixed in tempo or if it will just try to follow along the BPM setting from the Arranger. Abovementioned way would be a way to find that out I hope.
