I agree the vocal were better removed with Vogone 1, but to the cost of a lot of bass, drums and treble.
Vogone 2 is far superior in that it allows adjustment [and retaining the bass and treble]. It took me about 5 days [as a beta tester with no manual
] of devocing and playing around to start to know what to do. Now it takes me about 5 mins to set up and devoc a track ready for use with KHP.
Remember that someone will be singing over the top of this, I know its not perfect having a small bit of vocal left in. But hey its better getting the chance to sing songs that you want that will never appear on manufactured CDG's.
Persevere, you will get results.
