[list] [*] Gaps no longer crashes when the system has more than 10 inputs or outputs [*] Fixed a bug where after playing the degrees exercise two times in a row, the re-do notes would get messed up. [*] Drone note and the first melody note now start simultaneously on the melodies exercise. [*] Added a simple log system to debug audio problems. If you ever get any crashes you can find the logs at C:\Users\YOUR_USER\AppData\Local\Gaps\log.txt . If you send me this I'll help you with your problem. [/list]
