I'm trying to create an intro to a 32 measure jazz standard and I'm using using one of the BIAB realtracks trio rhythm sections.

My question: how do I create an 8 measure intro made up of the following?:

1) 8 measures of the bass player playing half notes on 1 and 3 of each measure, and
2) Piano player holding a whole note chord on 1 of each measure.

Can anyone tell me how to do this? I'm using v2016 (438)

Thank you.
