ok, so I had a quick look at this. after I replaced the serialosc bpatcher to make it to work with the current max version, the only thing that I could do with the patch is map the encoders to live parameters. I could be wrong, but it made me think that grainchild does nothing without that instrument chain in the video, which is not part of this distribution…
it looks like the patch is (or is largely) a rearrangement of this device, which is from the same authors (but also has an outdated serialosc bpatcher) http://www.maxforlive.com/library/device/2438/arc4-mapper
so I’m posting this updated version here so that people can at least use that arc to live parameter mapper… (the only thing I did was to update the serialosc bpatcher…)
