Pipe organ update

The pipe organ code was modified the last two days to use a ‘trendline’ method for voicing. This reduces the amount of data required to define a pipe to a handful of numbers, and will allow the entire parametric model of the St Just in Roseland church - some 32 stops, 35 ranks - to be encoded in a couple of kilobytes. Here is an early rendering - things will improve a LOT from here, this is using a small subset of the capabilities of this technique.

Not bad, eh? Watch this space.
