I'm putting this Pd patch out there as my #patternuary for 2023-01-20 because, sadly, I have no idea how to execute this in either #SuperCollider, #TidalCycles or #Strudel. A random melodic walk with a constrained choice of intervals. Direction reverses at upper and lower bounds. Crucially, syncopation is achived by throwing away any numbers that would repeat either the note before or, in this particular version of the patch, two notes before.
