MOTM

Hoping to get some suggestions:
Using the 700 for switching between cv's is great and is something that I
can easily do nicely.  However, switching between audio (say, between 2
300's) is something that I haven't been able to master, as of yet (yes, I
use the 'audio' switches on the 700). The main problem I encounter is an
audible 'click' when the switch occurs.

Any suggestions?  Maybe not running the 300's directly into the 700 but,
say, after filtering with an envelope that is set for a shorter duration
than the 'switching time' on the 700?

Thanks, Jeff
