Frank,thanks for all the great information!
Wow, I guess the FLR2003 will soon be
road worthy. With your software on a laptop
with perhaps one of the new firewire
interfaces, like the M-audio FIREWIRE 410
or Ego Systems QUATA-FIRE www.esi-pro.com/listProduct.php?ctgr=7
you could take your system anywhere.

I am sorry to hear that even the latest
version of SonarXL (2.2), has such horrible
latency even with ASIO drivers. I had always
gone with Cakewalk in the past, because of
their touted "user-friendly"ness, and
superior editing of midi files.
But,I have always found their latency unacceptable. I guess it's time to look into
Cubase.
Have you tried the standalone soundfont player called "Audio Compositor"? If so,
how does it compare to LiveSynthPro?

Doesn't Yamaha make their own softsynth
like the Roland Hypercanvas? I haven't tried Hypercanvas, but have heard that the Roland HQ-Orchestral is absolutely superb(and expensive).

Idatrod, this eKo thing does look
interesting, but out of my price range.
Nevertheless, it is a big step.
