Snipping audio to make a loop

[Ninjadog]

I have a sample imported into reason and I so far have isolated the loop I'm trying to use within the sample by setting the L and R markers. Now how can I delete unused ends of that sample and also get the proper BPM?

You can tap your tempo with the TAP button the transport bar. Be aware than after setting a new tempo the sample will stretch accordingly, so you have disable stretch by right clicking on the sample in the sequencer.

I just trim the clip and hit "P" to loop it rather than starting with the loop markers. Then I move the clip to bar #1, hit "Disable Stretch" and adjust the tempo until the loop fits the proper length (if it's one bar of music it should fill one bar at the proper tempo). If the clip doesn't exactly fit at a specific tempo, set the tempo so the clip is ever so slightly too long and then trim it to fit the bar exactly.
FINALLY, use "Bounce Clips to New Records" to "lock in" these changes. Now the tempo data is imbedded in the wave file - if you're going to use this loop in future projects, use the "Bounce Clips to Disk…" or "Export Loop as Audio File…" commands.

Thanks that helps a lot
