Avoiding PDC latency on live tracks.

OK, I'm thinking this through, help me out. I understand interface/DAW buffer latency, PDC etc. I've started doing live shows with pre-recorded backing tracks (one-man band). My live inputs (things like Guitar Rig or vocal effects) have no PDC. However my backing tracks sometimes do. Normally, whenever there is ANY plugin with PDC latency anywhere in the project, everything _including_ my live input monitoring is delayed by the largest PDC. However in my live scenario (where the inputs themselves don't have any latency), I want to avoid that. I don't care how delayed my _backing_ tracks are as I'm only playing along to them. So I think I want the option for Reaper to apply all PDC to my backing tracks only, without delaying the monitoring of my live tracks. (of course if I want to record those, then I still want PDC applied correctly to the recordings - but not the live monitoring). Make sense? Possible? Or am I missing something?

.. ok reading up on this, I should already get my desired behaviour, unless a live track has a relationship with a PDC-causing track (eg. send/return, or if a subgroup its in, or the master track has PDC). I thought I was clear of those but I will double-check ...

I don't know what routing are you having, and why PDC affects your live tracks, but you could always use different outputs for the live tracks directly to a hardware output bypassing any routing or plugin. or render the backing tracks and use them without plugins.

Thanks, I agree it must be a routing problem, some dependency I've overlooked (will check later). I have been rendering the backing tracks to a stem, but I want the flexibility of choosing a different tempo each night, so individual tracks are more useful.
