There is unstep[1] in netpd, which is a sequencer abstractions that
some instruments use. It's only able to trigger notes and has no notion
of note lengths or velocity, but number of rows and columns can be
dynamically set. It's based on an abstraction called ungrid[2] which
works also outside the netpd context and which comes a with a proper
help.
