I would have loved to, but I had to send it back when I realized that it didn't fill my "wish list" of must have features.
I use an iPad that must be monitored through those same speakers, along with my mic (into the built in harmonizer). The way Korg designed it, you can only monitor the line inputs, if the mic is not used. When you use the mic preamp, it disconnects the signal path of that second aux input. Weird.
