You assumed right. :)

Also check out JACK-Rack:

Does the same happen with ecasound? Here's a few things to try:
# basic ecamegapedal style rule
ecasound -i alsa,default -o alsa,default
# ...the same but with an effect
ecasound -i alsa,default -o alsa,default -pn:time_phaser1
# ...more buffering
ecasound -i alsa,default -o alsa,default -pn:time_phaser1 -z:intbuf
# ... 8bit only
ecasound -f:8,2,44100 -i alsa,default -o alsa,default -pn:time_phaser1 -z:intbuf
# ... use ALSA hw-interface
ecasound -f:8,2,44100 -i alsa,hw:0 -o alsa,hw:0
... you can also try running both as root and as normal user, and see if
there is any difference.

Hmm, running as root...?

Now this is problematic. I have one and it is a pretty lousy card
unfortunately. :( For example, you cannot do simultaneous 16bit playback
and recording. One of the streams has to be 8bit.
Audio software for Linux!
