I have one ReaClassical user on a beefy MacOS system who gets a "too many open files" error message when running this ReaClassical function:
https://raw.githubusercontent.com/ch...l_Audition.lua (assigned to keyboard shortcut A in the portable install). It works by starting playback where the mouse is hovering muting/soloing tracks as required. Note that when using in the regular arrange window, the only lines of concern are 33-48.
What's strange is that pressing spacebar doesn't cause an error. Admittedly, his project is quite massive compared to most (200 takes, 30-channel track groups etc) but I can't think what could be causing the error message in my function. It essentially sets the relevant tracks to muted or soloed, hides/shows the relevant tracks in the TCP/MCP and then runs OnPlayButton(). There's no io.open stuff here (as I found on another thread about the "too many files") and the muting/soloing iterates on a track level and not item level.
I can't recreate anything on my system because frankly I just don't have any projects of that magnitude.
