detonate & type 1 MIDI files

Hi,
if I make a MIDI file (not in Max) with tempo changes and save it as type 0, then detonate will read the tempo track and play the changes in tempo accordingly.
HOWEVER… if the same file is saved as type 1, the tempo changes are not recognized by detonate. No change in tempo occurs when detonate plays it.

Is this known or am I missing something?

Hoping for a quick resolution to this.
thanks
T
