Dead right :)

They are also useful with gate sequencers (often used to sequence
percussion or automate events). They also can be used as an "alarm" or
governer that stops or resets a patch after a certain set of conditions
have been met. In a similar way, a patch dependent sequencer can be set up
so that the logic monitors the patch and its output advances the sequencer
to the next step (the output of the logic module is clock input of the
sequencer).
Since logic gates are faster than audio, they can also be used with VCO's
-- using oscillator sync and PWM to play intervals and create different
harmonic structures. Likewise, a digital shift register can not only be
used a simple memory module, it can also be used an octave divider.
Of course, I'm sure the mad scientists on this list can come with all sorts
of ways to abuse logic modules with their MOTM system :)
