sequencing external midi expanders

[Cummings <r_t_cummings@compuserve.com>]

hello loopland, hope this isn't too off-topic:

my topic:
i'm using the mpc2000 to control a multitimbral midi expander (roland jv
1010). i program "msb bank select" and "lsb bank select" controller
change messages to select the sound bank and a "program change" to
select the patch. these are located at the first note of the first bar. 

my problem:
the actual sound of the patch gets cut off if a note occurs at the same
point (i.e. the "one" of the first bar) as the controller/ program
change messages.

my question:
how can i get around this?

thanks,
rob
