I remember a conversation with an IBM employee (family friend) early 90s when MCA was coming in: he was completely befuddled as to why anyone would want to be able to use an existing ISA card (like extra serial ports - remember them?) in a new PS/2 machine. Not really a surprise the architecture didn't actually survive.
Note that enabling/disabling the plug-in via the "System" button causes a big gap in the audio: not when doing individual sections of the plug-in (makes little sense to me but there you have it). The input gain makes things very fizzy and unpleasant. Compressor is nice.
I won't post a link to it as it's gratuitous self-promotion, but I/Xoo do (does?) have a song called Brain Tattoo available online...
Meanwhile, I feel obliged to:
