Final Comments

I hope you enjoy using the Oakley Classic VCA

If you have any problems with the module, an excellent source of support is the Oakley Sound
Forum at Muffwiggler.com. I am on this group, as well as many other users and builders of 
Oakley modules.

If you have a comment about this user manual, or have a found a mistake in it, then please do 
let me know.
 
Last but not least, can I say a big thank you to all of you who helped and inspired me. Thanks 
especially to all those nice people on the Synth-diy and Analogue Heaven mailing lists and to 
those at Muffwiggler.com forum.
