You may be thinking of MIDI sequences where you create actual loops. RP works with an audio bitstream. Analogous to MIDI = vector art (EPS math instructions) and WAV = raster art (JPEG bit-by-bit image).
The RP module simply replays your center audio file over and over thus creating the looping.

OK that’s what I was kind of wondering about the middle section if you had actually make the loop or if the RailPro assistant does it itself ,that should make it a little easier , so just out of curiosity should the first and last samples be a lot shorter than the middle ? I’ll experiment a little bit with it tonight see what I can come up with .
Thanks for all your help, John
William Brillinger:
download a few of the samples in the file section and have a look at them in audacity.

That is a personal artistic choice. What sounds good to your ear?
Ideally, all the files should be relatively short especially the first and last as their combined length determines minimum duration upon button press. The reality is you will be constrained by your source audio. The suitable cut points in your audio file ultimately determine how much latitude you have. For example look at the horn end selection in my example. It trails off very slowly. Not a great candidate as it means even a quick button press will still yield a long horn trail off. Your audio editor will have tools with which you can shorten the clip timeframe but use them with discretion. It is terribly easy to ruin the fidelity of the horn.
