USB is probably your biggest issue here, provided the raspberry can handle the
synthesis you want to do, you can help by assigning only a minimum of memory to
the GPU. No need to do any other rearranging of the system, with raspbian it
starts out headless (with X installed if you want to launch it) and capable of
quite low latencies. It has a basic minimum of processes running and ready to
add what you want from the extensive repository with apt-get. The settings to
work headless are mostly the default. These are great advantages in terms of
time required to get it running.

USB implementation is poor and only some audio cards work, plus something else
on USB like a midi input or networking will make it trickier. In your case,
needing only stereo out, it is certainly easier.

Seriously consider an audio solution that can use HDMI audio out.
