pickOuter(), pickRestart(), pickReset()

[eefano]

added pickr() and pickrmod() , see https://github.com/tidalcycles/strudel/issues/948

also fixed typos in inhabit() and inhabitmod()

The use of collect and restart here is cunning but I think will limit patterning possibilities. It'd be simpler and more flexible to use a trigZeroJoin. I think this might well involve changes to register to support, which currently has an innerJoin. Maybe this just needs a pick but with a trigZeroJoin

I'd say use of reset (trig) should be privileged over restart (trigZero), as the former is more 'patterny', although we can offer both as an option.

Maybe a nice solution would be to define pick as an operator, then all the different join variants would be automatically created, with aliases added if necessarily. Actually .reset is an alias for .keepif.trig. So pickReset could be an alias for .pick.trig then.

With my implementation of pickr() i can do something like that: "<[0,2] 1@2>".pickr(["a", "<b c>", "d"]).note()

And the result is equivalent to this looped indefinitely: "[a,d] b c"

When you use pick() , you have this loop instead: "[a,d] c b [a,d] b c"

• I'm using restart() because with reset() it doesn't work.
• I'm using collect() because [0,2] restarts both patterns twice, causing the output to double (in haps and volume).
• I'm incrementing by one the values because restart("0") does nothing

Now, assuming your API suggestions are implemented, can you please show me a strudel example that makes my use case work correctly?

[yaxu]

Hmm unfortunately defining pick as an operator doesn't really work as operators are defined to work on pairs of values, not patterns.

Howabout this?

These are the same as inhabit but with different joins (_pick is pasted in because it's not exported from signal.mjs)

Maybe it's clear from this how reset is more patterny..

[eefano]

Your approach is cleaner, for sure! But pickReset still doesn't work as I'd like. The equivalent output is: "[a,d] c b [a,d] b c"

pickRestart works as intended.

I'm keeping both in the PR.

[eefano]

I have added also pickOuter() , applying an outer join can achieve something useful like that:

"<0 1>/9".pickRestart(
  ["<rd*3 , <[[bd ~ bd] [~ ~ bd]]!3@2 [bd ~ bd] [~ bd bd]!2> , <[~ sd]!3@2 ~ sd!2> , cr/9>"
  ,"<rd*2 , <[[bd ~ bd] [bd ~ ~]]!3@2 [bd ~ bd] [~ bd bd]!2> , <[sd sd]!3@2 ~ sd!2> , cr/9>" 
  ]).pickOuter({
             rd:s('rd').gain(0.1).pan(0.4),
             bd:s('bd').gain(0.5),
             sd:s('sd').gain(0.5),
             cr:s('cr').gain(0.1).pan(0.6)}).bank("Linn9000").velocity(0.5)

these functions look very useful! maybe it makes sense to add pickSqueeze / pickmodSqueeze as synonyms for inhabit / inhabitmod to make the naming more consistent?

I also wonder if it would make sense to change the syntax from pickX to pick.x, e.g.:

"a b".pick.trig({...})
// instead of
"a b".pickReset({...})

this would follow the same convention as operators e.g.

"0 1".add.trig("0 1 2 3")

overview:

now	then
pick	pick, pick.in
pickOuter	pick.out
pickRestart	pick.trigzero
pickReset	pick.trig
inhabit	inhabit, pick.squeeze

I've omitted all the mod variants, because they are the same

not sure if it makes sense to add all operators, probably not

[eefano]

Pragmatically speaking, can this PR be merged as is by now ? I can work on a structured patch in the future.

I like this approach it seems a lot more flexible

[yaxu]

Maybe we should standardise on the friendlier reset and restart rather than trig and trigZero?

Yes pick.x would be nice, as would moving towards supporting this in general, across all patterning function parameters. Tricky for functions with higher arity though..

[eefano]

I tried to introduce the mux operator but tests don't pass, so i reverted. At the moment I'm not knowledgeable enough to provide a better solution. I hope you'll integrate pickOuter, pickReset, pickRestart soon. A better solution can be thought out in the future.

now tracking this here: https://github.com/tidalcycles/strudel/issues/970

[felixroos]

I've renamed pickOuter to pickOut for consistency with the alignment operators. I'd merge this now, but maybe we'll get the dot notation with https://github.com/tidalcycles/strudel/issues/970

[felixroos]

For now I'd consider these functions experimental, as they might get renamed later

and thanks @eefano :)

thank you Felix, this is very useful!
