they are a couple of simple test apps i made (looping and shaped noise)
they were in the aleph repo but removed in this commit, because the underlying ‘OS’ layer had changed and it did not seem worth maintaining them.
now there is a single demo app which is just a mixer: https://github.com/monome/aleph/tree/dev/apps/mix/
it is verbosely documented and intended to be used as a template for custom non-BEES control applications.
the big text is available in C with region_string_aa functions, as used by bees BIGNUM operator.
