Early verdict : Ultrarez rocks.
Questions : Will we see ultrarez versions of the producer packs? Extra charge?
I will likely be hitting up the Ownerhammer stuff shortly.
Unfortunately we acquired the Producer Packs at only 2K samples so there would be no advantage to converting them to UltraRes. We have already lined up studio time to go and acquire new IRs and will be offering those in UltraRes format. I've acquired some new amps since the last time so there should be more variety too. Also, we've been in contact with some studios and IR companies about producing UltraRes content.
CabLab will be able to automate the whole IR capture process (the hooks are already in the firmware). So you start up CabLab and it guides you through the IR capture and then saves both the raw IR and the UltraRes sysex file. Basically all you have to do is enter the file name and hit "Go".
We will be offering commercial licenses of CabLab to those companies who want to produce UltraRes content.
