Great application - great developer!
I am running the audio for a broadway class, musical production and needed an app that could handle multiple channels playing simultaneously, loading lots of cues for music and sound effects (upwards of 150), easily nagivate bettwen cues and set the sound level independently for each cue. And most important - run stable. Ive used MiX16 Pro for three weeks now in rehearsals (multiple hours per day) with no crashes, on my Dual Core MacBook (OS X 10.8.5). I had a few suggestions after initially purchasing it. The developers response time was near immediate. He listened to my input and quickly implemented multiple feature requests (coded, tested and released through Apple within two weeks) -- two of which save a tremendous amount of time preparing and changing cues. I would highly recommend this app if you need to run audio and/or video in a show environment. And the support is first class! One tip from the developer that I use -- if you need more than 64 audio cues per set and have unused video channels, you can convert the audio files into M4A format, rename them to MP4 and load them up in the video channels (setting Fade Source to Audio). This gives you up to 64 additional audio channels in a single set, which in my situation have been a significant benefit.
