Hi Maex

Interesting stuff. How are your experiences with the audioselect 
switches? Isn't it to harsh swicthing the sound?

I am planning some live-rack which will contain for each Audio-module an 
addon module:
This module will duplicate all audio outputs and provide two audio 
inputs which can be crossfaded. It would be much easier to implement it 
with a switch instead of the crossfader.

The idea is, that is usually impossible to remove or add modules to a 
signal path while playing live. With my dual-out/crossfaded-ins module 
it could work like this:

---- = audible Signal

.... = Signal suppressed by crossfader

Step one: VCO feeds VCF
#####  +-----------------------o     #####
#   #  |                       |     #   #
#vco>--+                      xfad--->vcf#
#   #  |                       .     #   #
#####  +                       o     #####



Step two: add Phaser to second out-path of VCO:
#####  +-----------------------o     #####
#   #  |                       |     #   #
#vco>>>+                      xfad--->vcf#
#   #  |      ########         .     #   #
#####  +------#phaser#.........o     #####
               ########


Step three: crossfade the VCF in to the phased signal:
#####  +.......................o     #####
#   #  |                       .     #   #
#vco>--+                      xfad--->vcf#
#   #  |      ########         |     #   #
#####  +------#phaser#---------o     #####
               ########
