Unless I misread it said earlier that your offering presets for different manufacturer's, which brands are you including and do you have any Peavey Versarray presets, I like your Navigator software and have been playing with it for a few days, I always intended to have this type of PC control for my system and actually bought a Laptop and tablet just for this use, Both HP, I also use the USB to Serial converter for my Current Digitool Crossover system, But I may consider a change. The 4800 Looks like a very nice DSP, Would love to use one for a couple weeks.
