From bd1935c924b98eb6afdf41c117e26487660c596c Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add some temporary hacks to the votrax to get the parameters
 to all change to real values so the analog filters can be tested.

Changed USE_FAKE_VOTRAX back to 1. Was accidentally checked in
the wrong way in a previous change.
