The midi clock sych. thing doesn't work, not even for 1,2,3,4 beats.

The effects are not that great.

The isolator is the only cool thing.

Other than that, it's only a four channel mixer. For 1150 bones?

I had one for 2 two days before I returned it.

If the price was half of what it is I would give it a rating of '4' but as it stands it gets a '2'.

Sorry Roland but your GROOVE mixer SUCKS.
