Thank you both!
I checked out 1.9-dev and still everything I was missing was still missing. I found some of it in Sound/Tidal/OldUI.hs, and I've restored those functions (not the whole module -- I tried that and it seemed hard) by copying them to a module that does get imported.
@archaic.tech I just run it from source. I've made a few minor contributions but I'm certainly not developing Tidal. I did try once, making an elaborate fork that used strict rather than lazy patterns, which were aware of their own duration, making concatenating things of different lengths easier -- but Tidal has evolved to the point where I don't think that branch offers much any more.
I use a few short definitions. One that I call hz, which is like n but takes a frequency value in Hz rather than fractions of an octave. Two functions meta (apply a patter of functions to a pattern) and replace (use a map to substitute other stuff in for a sequence on arbitrary symbols) that I had defined in horribly complex ways until @mvdirty found beautiful one-liners for them. A few synonyms (quantize instead of quantise, timecat rather than timeCat, etc.)
I've defined and used lots of other things in the past, but lost or forgot how to use most of them, and I doubt any of that stuff would be of interest to others.
