Multimode and Sequencing

[ixian]

Hi, I'm pretty new to synths etc and I was wondering if it would be possible to achieve the following?

Equipment:
- Rev2 Desktop
- Roland RD88 Keyboard
- Arturia Beatstep Pro (BSP)

Connections:
- RD88 midi out to BSP midi in
- BSP midi out to Rev2 midi in

Desired Outcome:
I'd like to create a sequence, have that sequence run while I play live on my keyboard.

Questions:
- Firstly, can I live record/enter a sequence into the BSP using my RD88
- Do I need to use multimode
- If so, do I run that sequence using a midi channel for layer A of my Rev2 while I play live on the RD88 using another midi channel for layer B

Hope I have explained that well. Thanks.
