e start slow end fast?', 'I want to lay drums down for this song where each verse slowly speeds up, then bang the chorus back to original tempo. Next verse, starts to speed up again, etc.

I am using Reaper and I know Reaper has playrate/tempo automation etc, but will Jamstix cope with that?

Or, do I just get Jamstix to lay down the song, then manually do the speeding up for each verse afterwards?

Thanks.

Jamsix will handle the tempo changes from the tempo track in the host. I have even used tempo ramps (as opposed to jumps) in Cubase with no problems.
