Hi,
I have just released 'planifolia', a set of abstractions designed to work without compiled externals.
Among the the implemented processes, there are tools like arbitrary unary and binary operations in lists and arrays, quicksort, logical operators to check equality of arbitrary data types, easy OSC formatting/routing, etc.
It also comes with toggle-based matrix GUI (designed to work be compatible with `iemmatrix` objects) and a matrix based step sequencer with some non usual features (independent tempo, beat and duration patterns, col/row/colrow modes, nice colors, etc). You can check the step sequencer here:

It is in my github and I have just uploaded to deken (first time, I hope to have done it in the right way!).
Hope it may be useful to PD people!
cheers!
