I still have this group active and while I don't use KeyKit in any capacity as of late, I think it's important to break barriers to accessibility of old software if possible if for no other reason than to inspire future creators to see what has been done before already. I think the real tragedy of KeyKit disappearing into obscurity would be for someone to reinvent the exact same thing on a new platform having not known this place has been treaded before and that work could've been made more useful by improving the concept in some way.
That's just my input as a non-user thinking more broadly. There's a lot of things I don't use in the software world that I'm glad exist for both users and developers to see what's been done before, something I think is exceptionally lacking in the software world in general for one reason or another to which I have no answer nor explanation for.
I hope my drunken screed here in some way at least encourages the preservation of KeyKit by someone who both knows what they're doing with the source and can at least put it in front of people to inspire the next generation of what this tool's concept embodies: MIDI tomfoolery for fun and experimentation.
Thanks for the KeyKit that exists. I did use it, never understood the scripting language at all, but absolutely had a blast hooking up the existing machines in the software to virtual and physical machines. Hearing my ESX smash out drums based on a ball bounce in a box is an experience I don't think many electronic musicians get to experience, at least in the context of 'here's a videogame making your actual hardware do sound' type of situation.
And of course there's the plethora of more useful tools. The entire point I guess I'm making is to wave 'hi!' and say 'while I can't report that Keykit is an indispensable part of my music studio, i would be a lesser person with how I think of music if I never tried it out'. And I hope it's always available for anyone else to have a similar kind of experience.
