Re: merging mono files

I stated trumpet to give an example. I am processing pipe organs. Pipe 
organs have different stops representing different sounds some emulating 
and therefore named after the instruments they represent. Each stop 
activates that sound for a rage of keys, usually around 61 keys. Each 
key pressed will open an airflow vent that channels wind into a pipe and 
sound is produced. Successive keys will generate sound from one 
(sometimes as many as 20+ pipes) of an array of pipes positioned across 
from left to right so one note sounds from a pipe to the left and the 
next, a pipe on the right, the next from the left and so on. Since these 
pipes in real life are next to each other and occupy a fairly wide space 
the stereo recording are used to give that sensation of the pipes' 
spacial distribution when played digitally. So it's not a matter of a 
simple left and right.

Loops are needed to perpetuate the sound for the duration of time a key 
is pressed even though a recorded sample may be of just 6 seconds' 
duration. The software loops the sound until the key is release. I have 
mentioned this before.

This video may give a bit more insight in what is to be achieved:
