Searching for the ambi.granulate~ external

Hello

Yes the ambi.granulate~ was part of the ambisonics externals I released 12 years ago (Max 4 days). It didn't seem to make sense to update them since the ICST and HOA libraries were so actively developed. Sadly I can't find the source code anywhere, but it seems to be mainly a delay-based granulator with ranges for density, amplitude, length etc., and XYZ direction for encoding, outputting 1st, 2nd or 3rd order harmonics. I wrote another spatialized granulator for the Cosm library (Max 5 days), which was a wavetable-based thing, responding to jitter matrices of grain properties -- which made sense with the multi-agent system model of Cosm. Again, a lot of Cosm became obsolete with features introduced in Max 6, so Cosm wasn't developed further. Moreover, in both cases the granulation was pretty idiosyncratic, as it is hard to make generic granular synthesis in a Max external.

These days I would recommend writing such things in gen~ of course, where they are more editable and portable. It wouldn't be hard for example to adapt the gen~ OLA examples I wrote (in the gen~ examples folder of Max) to take XYZ direction vectors and output grains spatialized on 1st order WXYZ channels. (Higher orders wouldn't be hard either, just a bit more fiddly) -- and then spatializing over speakers/headphones etc. with the ICST or HOA libs for example.
