hmm great info...expensive but man that would be sweet... we have a whole living room full of songbooks, take foreve to scan in tho I guess... can it be set up for 2 or more people to look at the same sheet of music at the same time like each one having there own computer monitor or something.. and one person controlls the main unit with a footswitch etc.. like if your had 4-5 people playing the same part they could all read the same music at the same time... or would they each have to gulp spend the $1100 to indiviual ones... I guess my question is can they be chained together ???
