Hi Andrew; thanks for replying so quickly.

Absolutely! The same performance was recorded both from the soundboard and from what sounds like some shotgun mics close to the stage. Ironically, the soundboard version wasn't commercial released.
I only meant that if there are any pitch correction issues, I can tune them exactly alike.

That's somewhat discouraging.

I never thought of inserting silence as a way of nudging tracks forward, since I erroneously assumed that inserted silence replaces existing audio.

I actually have Reaper, OSARA and SWX on my machine. I'm part of the Reapers Without Peepers email list and the Whatsapp group. But I've been hesitant to take the plunge, mostly because I can't quite get my head around some of Reaper's conceptual nomenclature, specifically items.
Multiple items can apparently appear on the same track, either successively or simultaneously. If an entire track consists of one item and I split it into clips, how many clips will be created? Reaper also can apparently merge audio and MIDI on to a single mono or stereo track, with different effects or envelopes on each item.
This sounds like bouncing tracks, which seems entirely antiquated and unnecessary in the digital domain. I'm trying to imagine a scenario where you have two audio items sounding simultaneously on a single stereo track, and one could apply different effects and envelopes to each of those items. Please forgive these admittedly off-topic and elementary questions.
