Do you know of a piece of equipment that would electronically add orchestration to my "live" guitar playing through my amp?
ANSWER
Hi, mpcputt--
There are a lot of different ways to add orchestration live.
Probably the easiest way is to use a sequencer. Of course you have to write the parts first. I don't know of piece of equipment that will write parts on the fly.
If you write the parts using a keyboard and a sequencer/sound module, then you can save the song to your sequencer and then hook it up to your amp or,even better, your PA system.
Then you have top be very precise in your guitar playing because the sequenced parts do not allow for mistakes or variations in rhythm.
If you want to use computer based software to write your orchestration, you will find a large selection at:
