hello 

i am working to create an environment in MAX to be able to control ALL
of the sid station parameters from a graphical interface. the continuous
controllers are no problem - but a lot of the good stuff needs sysex
control. i have been reading previous posts on how to control the sid
via sysex and still can't get my sid to respond to any sysex messages.
if anyone with experience with controlling the sid via sysex or
controlling anything via sysex from max could provide some pointers that
would be fantastic. once it is all together i'll make a standalone (mac
only) application that i will be more than glad to distribute freely.

thanks so much
