Donny, most of your work is adding vocal tracks to an audio track... The PC namely MixCraft is perfect for this..

But what we are referring to is sequencing... midi data recording and editing..

Even the Fantom doesn't match the G70 for this...It is too time consuming.

Here is an example...On the G70 you can record a style play with muted tracks, as a midi capture.. send it to the on board sequencer, record any tracks over it you like, and edit anything you want.. Resave as a SMF.... Now try that on the fantom.. My example maybe takes 1/2 an hour.. tops.... Your Fantom, I'll check back with you tomorrow....and help you finish it.
