I'm considering purchasing an Audio4+.
Before taking the plunge, there are two issues of concern:
I just checked the update log for firmware on this unit. One thing I
noticed was that there was an update for version 2 hardware. So:
a. What is the difference between version 2 hardware and earlier
versions? (I can't find any reference to this on the iConnectivity
b. How can I be sure that any unit I buy is the latest
hardware? (This is of particular concern because I'd be buying in Japan
and might be buying older stock. I do intend to buy a new unit rather
2. A significant reason for buying the
Audio4+ is that my PreSonus AudioBox iTwo (which I use for performing
live with sound apps on an iPad Air) has a MIDI problem with certain
keyboards when they send MIDI time code. With certain keyboards (Korg
N1, Yamaha CP33, but not my Yamaha KX88) this results in missed note
ons, incorrect velocity transmission and stuck notes. I don't need MIDI
time code (everything is played live with the band) so this is
manageable with keyboards (Korg N1) which allow time code output to be
disabled, but insurmountable with keyboards (like the Yamaha CP33) which
don't allow this. (On the CP33 at my local rehearsal studio I'm forced
to rely on my iRig MIDI interface, which works fine.)
a. Has anyone experienced this kind of problem with iC Audio4+?
b. Is it possible to block selected MIDI messages inside the Audio4+ so that they never reach the iPad?
Thanks in anticipation.
