I use and i pad for words with songbook+ app. I use karoake anywhere for my backup tracks if I need to. 99 percent of my playing is live but sometime you just can't do that with uptown funk for example in that case i play along with karoake track that I transposed into my key with ipad.
My styles are all filed by swing, rock latin,ect. I have some listed as mis . This I use for special songs I also have a show file where my show favorites are stored. My karoake tracks that i play along with are also on songbook on my pa1000 with the key ,and 4 sounds for each song. I can get to a sone just by sececting it and push start. I know what style a song is so I can just go tho that syyle select the song in that catagory and play. Kind of like a mini songbook. works for me
