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
