Yes! The Organelle is running Pd 0.46 vanilla. It has a small number of extra externals that are only used in the mother patch (the patch that communicates with the hardware):
for Open Sound Control communications:
udpsend
udpreceive
packOSC
routeOSC
unpackOSC
slipenc
slipdec
for audio output:
pvu~
tb_peakcomp~
We decided to keep the included externals to a minimum, and if a patch needs something, it can include it on a case by case basis. For example the Analog Style patch uses the moog~ filter object which is just included in the folder with the patch. The Organelle does include a compiler (gcc) so you can compile externals directly on the device, which is how we compiled all the ones above.
