A further additional request is to have a filter on the pitch notes/voices.
In some instance you want to roll off the higher frequencies on the pitch note to better mix/blend with the original note.
Afterall no 2 guitar players will have exactly the same eq as each other and this is part of the magic of a two guitar harmonising band.
As we know many guitarists will be on the neck pickup whilst the other guitarist is on the bridge pickup. Add to that the two guitarists are never perfectly in sync and this is the reason to slightly delay the pitch notes to further replicate the effect of two guitarists.
Hopefully this can be implemented and if so my H8000 will be finally laid to rest.
