Yes, I'm Geraint. :D I'm the tech side of Signalsmith Audio, and my partner is the Business Brain. The JSFX plugins are mostly from before we made a proper company (back when Signalsmith was just my username) - I'm glad you're enjoying them!

Neither am I, most of the fun is in the software anyway. The rest is just some amateurish solder work and compiling an array of components I may or may not use.
