I have three tracks ready to render but when I try to, Synth V just crashes, I’ve never had this happen before and I have tried changing it from stereo to mono, and how many tracks to render etc. yet it still crashes every time, is there a way to fix this? 
Could you send me the project file so I can run a test?
Bug confirmed. Will fix.

The crash is caused by the “???” characters in the track names. The program attempted to create files named “output - ???.wav” but question mark is a system-reserved character. In build 016 I will make the program auto-rename tracks containing invalid characters. For now, please rename the tracks manually.
