Mac OS and velocity curves

Hi Jeremy,

I tried installing for Mac, but it hits an issue and won't allow it to install on the current OS.

I ran in Windows and got the program working. I ran into an issue where the velocity curves don't save. I changed them, reloaded and they defaulted back to the original set in the software.

A couple of times the software would not save and I had to unplug and reload.

Kind regards,

Conrad

Here is the log for the error in the software:
