The defines are in asound.h file - look for 'Timer section - /dev/snd/timer'.
Usage (using defaults):
options snd-seq snd_seq_default_timer_device=1
or (full specification):
options snd-seq snd_seq_default_timer_class=1 \
snd_seq_default_timer_sclass=0 \
snd_seq_default_timer_card=-1 \
snd_seq_default_timer_device=1 \
snd_seq_default_timer_subdevice=0
