Hello Heinrich,
It all sounds very interesting. How about for strictly live performance? I currently play midi accordion and/or a PA60 with a Master MK4 controller and/or Korg i40m module w/hard drive (I’m in the process of selling my PA1XPRO-super board-just too heavy to lug on gigs). What kind of lap top set-up do you think would be feasible using the midi accordion and/or the PA60/MK4 combination as controllers? Presently, I use anywhere from 30% to 80% midi files depending on the gig. I use Band in a Box files that are edited with Power Tracks as well as many others that I sequenced, purchased or downloaded from the web. Are there programs that will allow you to play “live” arrangements with a controller? I’ve seen a lot of musicians using a lap top, but usually with midi or mp3 accompaniment, I’ve never seen anyone use it as an arranger “live”. Is it really possible?
Ciao,
Jerry
