Sending CC 98 as simple CC (not part of NRPN)

Hey hey,
I'm working with a soft synth that uses CC 98 to control a lot of parameters. 
I tried setting diev/doev to the empty list and still Midish refuses.
taddev 1 0 0 {xctl softsynth 98 80}
controller is reserved for bank, rpn, nrpn

Is there a way around this? Unfortunately I can't reconfigure the softsynth, 
CC 98 is hardcoded.

Best wishes and thanks,

Jeanette
