I use my LP-16 almost exclusively in interface mode. It is great for using it in a virtual instrument, especially pipe organ emulation.
While I realize there can’t be too many people using it for that purpose, still it would be great to be able to re-assign outputs. For example I’d like to be able send the outputs of channels one and two to channels five and six.
In interface mode, working without a mixer–yes! I use nine (9) amplifiers and 18 speakers–it can be inconvenient to unplug jacks just to re-route signals.
If you have a more convenient method to accomplish this, I’d like to know about it.
