i have a disklavier mark iv and the prc-100 will not connect to the mark
iv. controller still has interface, no connect. it is running version 2
of the software and would like to upgrade. i was told i have to upgrade
to 3 then thru an internet connection i can upgrade to 4. problem is
the mark iv is not on line, is the prc-100 the only way to get the mark
iv on line. second question is can i up grade the software on the mark
iv with out it being online, and does the upgraded software give me any
more control over getting the mark iv online with out a prc-100. lastly,
do you know where i could rent a prc-100 for an hour
