How can I vary shuffle rhythm in recording with Reason?

Question

I've been handed a few audio tracks from a local beginning artist. I'm struggling with various shuffle rhythms from the artist on guitar. I'm tasked with writing accompanying tracks (piano, strings, etc.) on the computer.

I have broken down shuffle rhythm in separate lanes, as such:

The main problem I have is that, for each additional instrument, with the current setup I will need to make 3 lanes each to account for the varying degrees of shuffle (with respective ReGroove patches A1, A2, A3). Is there a smarter way of doing this with Reason?

Answer 1

As indicated by the comment from GavinH:

To my knowledge, there is no way to automate the groove channel parameters, nor the selected groove channel for a track. I'm assuming the song changes between straight and triplet feel, you could always quantise your notes accordingly.

I have found that there is indeed not a way to do this without breaking down the sequenced notes between several tracks, one for each Groove channel in Reason.
