I just got this and haven’t had much time to play with it – but so far I’m digging it.
4 inputs, 4 outputs. The in/out level controls are dedicated knobs on the front panel. You can define 4 different effects with each channel or combine them. You can also stack up to four effects (4 reverbs in series anyone?). I’ve also seen it has a 4 band vocoder but I haven’t played with it yet. At first glance the programming is a little funky but another hour playing with it and I’m sure I’ll figure it out.
All this in a nice two unit case.
