Had my first gig with the S4 last night. All went well and I really enjoyed using it. Played for 6hrs straight without any problems.
During the gig I found you can ffwd and rwd through the track in preview by turning the browse knob making track preview pretty much ideal.
Headphone vol wasn't as loud as I thought it might be. Wasn't anywhere near full but higher than I have it on Other mixers.
Really enjoying how you can have options for mixing in sync or synced and then using the jog wheels or unsynced and jogwheels for the turntable feel.
Noticed the mixer section looked pretty grubby today after a nights use. A downside of the high gloss finish.
