I'm a DJ and I'm using MixMeister Fusion mixing software while playing. I have a USB audio converter so I can play lively with macbook pro's output and preview transitions with the USB audio converter's output. Also I'm using Audio Hijacker Pro to record my live performance. I was testing them by playing 50 minutes. However suddenly, MixMeister stopped playing and said: Application quitted unexpactedly. I have 4 GB ram and 2.8 processor. If this will happen while i'm djing, it will be shameful for me. Is there any solution? please help me. Thanks.
