I recently purchased the online upgrade from Studio One 2 Professional to Studio One 3 Professional, and ever since there have been crackling noises in the playback of my recordings. I'm working on both an iMac 27' 2010 & Macbook Pro 2011, both with Yosemite installed. Mostly recording through Apogee Duet. I checked my hardware, cables, and instruments, but the crackling sound also occurs with digital instruments where I haven't used any hardware outside of my computer. Also the sound doesn't always occur on every channel, and the sound appears to have a rhythmic pattern and thus is not completely random. The strange thing about it is that when exporting stems and mixdowns the clicking noise does not occur on every individual channel, but rather 'randomly' occurs on some channels sometimes (so it happened to me that the clicking did occur within Studio One, but not in the export and vice versa). Handy information might be that the clicking noise is affected by plugins, so if I use an OpenAir reverb on a specific channel with that noise, the noise gets that reverb. Also if I arm a track for recording, without recording but just playing something to do a soundcheck, the crackling sound already occurs. The sound only occurs when playing a track with sound information, so it won't occur when I'm playing an empty track or just a metronome.
I've tried changing buffer size, turning off my plugins, reducing channels, tried checking my electricity cables/wiring, looked on the internet for the problem, but haven't found a solution yet..
It seems to me that it is a software problem within Studio One 3, as I haven't changed computers, haven't added or removed plugins, and didn't have this problem in Studio One 2.
Thanks in advance,
