I just did a test to make sure that the "Single" setting is actually getting set - and you can confirm this dear users, but I believe it is working just fine. Some clarification, however, may be helpful.
Normally, the JMCL software defaults to "Loop" for the Loop Mode setting. That makes sense because, well, it's a looper! But for those of you that need certain loops to NOT loop, here are the steps as I know them:
1. After you drag your loop to a slot, change the Loop Mode dropdown setting to "Single".
2. That's it!
Before you "Save" (to take your card "on the road") I always recommend you spot check that your settings are indeed set by simply clicking on your slots and looking down in the lower property area to see that your WAV loop matches your desired settings.
Keep in mind that this is "open source" software. You can view the code and find all my bugs here: https://bitbucket.org/birdwellmusic/jammanloopermanager
