Information please

I have had the opportunity to purchase a Ketron 76 but I would like help with the following please:

If I import mp3s or wavs, can the vocals be taken out as in midifiles?

Can the chords to songs etc, be shown on the screen?

Can a set of numbers/songs be saved to the hard drive to be used at live gigs?

Are there any tutorial books on setup etc, available anywhere?

Thanks very much for all/any input

Yes (but there are considerations)
Yes (with some work)
Yes - in folders
No afaik - just the owners manual. Just make sure you buy from a reputable Ketron retailer and you will be ok. I suggest calling Trevor in Northampton on 01604 637444. He sometimes has B stock or may know of a customer who wants to sell.

Many thanks Tonewheeldude, can you elaborate please?
