Hmm, there seems to be something odd in the preset handling. I copied the
whole metronome definition from 'effect_presets', and it seems to work as
expected:

--cut--
ecasound -i:null -o:test.wav -el:sine_fcac,880,1 -eemb:100,10 -efl:2000 -t:4
[...]
###| ~ |$ ecalength test.wav
test.wav: 4.011s (0m4s)
--cut--

Also altering the tempo (1st -eemb parameter) works as expected (tempo
changes, but the output is still always 4s long).
