ZeRO SL Mk II has been designed to give you complete control over your music making software. We have worked with each of the major DAWs to make sure each of the 56 knobs, faders and buttons control the things in your software that you need them to control. However, the really clever bit is that SL MkII can directly control your plug-in instruments and FX. The control surface is almost identical to the SL MkII keyboards, but it has longer throw faders (60mm) and a central crossfader. Lightweight and bus powered, it is a firm favourite with performers.
