Comment 2 for bug 375575

I think you are right. I only tested with a small test project I did and there I could reproduce the problem reliably. I now created a new project with only one instrument and it works fine. Adding a new instrument it still works fine as long as I set the other (non-recording) instrument to mute. Once the problem happens once, it does not seem to matter what I do: I need to restart jokosher to have it behave correctly again.
