low-level voice-bleedthrough -- should be fixable in firmware #16

This is a known issue, just adding it here for completion. Here is one group members analysis:

"It is 100% fixable through software. I'll leave this as an exercise for the reader, but if you take a moment to play a few random notes then crank the volume, you'll notice that there will most likely be a decent amount of bleed-through. Now take the VCF LEVEL, SINE LEVEL, and LEVEL controls wobble them to gain control and take them all the way down to 0 (for both oscs). The bleed-through becomes almost imperceptible. If you look at the schematic, these are all digitally controlled parameters of the voice (and if you'll notice, the bleed-through also disappears after switching presets). All Black Corp needs to do is make sure that after a voice has reached the end of it's release cycle that they floor those params. Theoretically easy as pie."

In the upcoming v1.2.4 update the bleedthrough has been minimized as much as possible for the Rev1 hardware by lowering "VCF Level" I and II parameters to 0 when all voices are silent. I have tested this both with db measurements in my DAW and with my ears and it is a big improvement.
