This is true, I am running series routing as parallel routing no good for some effect set-ups as it mixes left and right somewhat (no use for micropitchshift for example or different delays on each channel when you need a clear left and right separation to get the full effect)
On my Timefactor pedal, the mix control mixes the dry and wet signal together maintaining a stable volume which would be of great use on the Eclipse set-up I am using.
Apart from this downfall (which I got round by adding a Timefactor pedal to the chain) the Eclipse is one awesome piece of kit indeed. Perhaps a tweek to the mix parameter on the Eclipse a thought for the next software update? (if indeed there is one?)
Many thanks for trying to help on this issue anyway, and keep up the good work!
