LogicalDemo was one of the plugins from the Character collection, but it was never included with them because (like Elation) it had special behavior, namely compression. From the word go, Logical was setting out to be a 2-buss compressor.
Controls were similar to the Character plugs, including a Personality control which handled the application of a convolution impulse. Like the other Character plugins, this wasn’t just an impulse (from SSL gear) but a dynamic extrapolation from two impulses at very different gain levels.
You should be using the most current Logical, it’s much better as a compressor. But, if you want a copy of the first Logical, buy the current one and then ask me in email. I’ll send you one.
