Hello folks. I am new here today, and seek advice on the feasibility of using BIAB for accompaniment, played through a laptop for live performance.
I am an old-timer [live bands in the 60's-70's], and now just play as a solo act 5-6 times a month,
for mainly seniors groups,like day-aways and nursing homes.
I currently use an acoustic-electric guitar and an 'M-Audio Black Box Reloaded' as a drum machine, to back up my vocals.
Indoors I run them all through a Fender Acoustasonic 2 channel amp, outdoors I use a 70's Yamaha mixer amp and columns for voice and drums, and just run guitar through the Fender.
Why I'd like to upgrade is twofold:
-The Black Box has no 3/4 time beats at all, a bit frustrating.
-I'd like to add a bass line if feasible, and perhaps a rhythm guitar or piano line.
I usually play about 30 songs each show, from a repertoire of about 300 altogether.
I have plenty of time between bookings to sort out a program of 30 songs from my total listings, but
I do requests also, so need fast access to any preprogrammed song.
I'd love for the software to have the capability of me accessing a lyric/chord sheet,
while a track plays, as I sometimes need to quickly refer to a lyric for about 150 of my songs.
I don't have a laptop at present, but my desktop at home is due for replacement, and even though I dislike
laptops, I can tolerate them if I use a mouse.
What I envision may not be feasible...a laptop I can punch up a menu of songs, click on the one I want to do, have the lyric sheet pop up, and start playing my accompaniment...direct from laptop to amplifier.
Any suggestions and/or advice would be most appreciated. Sorry my post is so long.
