Hi I'm a newbie to the whole idea of software instruments and sequencing. If I make a 4 bar bass and drum part in the sequencer I can't see how to cut and paste or to just copy the loop out to maybe something like a 25 or 30 bar song. I didnt find it in the manual and I played around with the icons on the sequencer but to no luck. Thank you for your help.

I forgot to mention I'm running Reason 3.0

Right click on the instrument sequencer and copy pattern to track. Hit the Enable Pattern button located above the run button on the redrum to disable hit and hit play. You can also automate which is easier for pattern changes. Buy any reason tutorial it'll help you out alot. Too hard to explain in a forum, you're gonna need to see pics and videos to make it easier.

If you have copied the loop to track it should be a case of right clicking the loop you want to copy and then right click paste within it's sequencer track, note you can't cut and paste whilst the song is playing. If you put the notes in youself you can colour co-ordinate your loops using the pen tool at the top of the sequencer. This makes cutting and pasteing allot easier. Make sure that you have the "snap" on and set to 1 bar or half a bar etc.
