i don't think so ... maybe it was the master/headphone volume pot i don't know. But i wrote the kit and what pad i use (kick) and level volume when i did my test. i usually use my Beyer Custom Studio Pro with a really devil EQ curve (heavy bass) to try how sound kick with heavy EQing in Low so then i know how it sound with the most drastic EQing... i never reach this point but if my kick is bad ass with this curve i know i have room to get exactly what i want in the mix.
it was awful with the same kit, same kick, same level... but with this MPC the kick sound ok so it's cool
For mixing i use my Focal CMS 50 (+ sub for Low end shaping then i cut OFF the sub), Beyer Custom Studio Pro (Linear and Vibrant Bass check) and AKG K702 (For Pan and Reverb on the road)
Didn't like a close headphone to open up the sound like stereo enhancement, M/S processing, PAN, Reverb... AKG K702 is very cool for that, of course not a replacement of proper monitoring system... but way better than a close headphone everyday
- i receive both unit on the morning when i getup so my hears was initialized
