Regarding upgrade cost ...
I am currently updating my V 6 instruments. No mention of paying for new versions. Only CMI has finished installing. I had to re-register it, but that's quick and painless. Now works just as it used to. I see nothing new about it, I'll hafta read the release notes. ... No sign of recording into the sequencer by playing your MIDI keyboard tho. I sure hope that gets added.
Anyhow, based on this, it looks like V 6 owners simply have to upgrade and do a re-register on everything. Only a very mild annoyance.
So basically it's 3 new instruments, plus whatever they did to the Hammond.
Regarding the apparent change in Analog Lab to only have a selection of presets for all the instruments .... I can kinda understand that really. I mean, all on its own with no full versions, it gives you a VAST selection of sounds plus extensive control to modify those sounds to new sounds. Pretty much being able to mostly use each synth on its own, but of course not to the full extent as you can if you purchase it. I've always been surprised that Analog Lab contained all the presets, frankly. .. And I appear to have perpeputal upgrade, since I also own the MiniLab (mk 1) \o/ Yay
Frankly tho, I rarely actually use Analog Lab. I just opened the instrument I want ... I've been wondering tho, what's the system overhead for running Analog Lab to use one synth from "inside" it. It is nice to be able to browse and access the FULL "studio" of synths, and then when I find something, open it up and start messing with it. .. But if I'm starting something new, I'll just go directly to the specific instrument. <shrug> I dunno. I can understand people being upset about it too.
