Adding crow~

[zzsnzmn]

Still a bit of a WIP, but the main plumbing is there.

We can either take 2 or 3 arguments, depending on whether we want the channel to be built into the op name.

I think my favorite is (by example) something like

CROW.V= 1 SN K

Which will copy the voltage on bus K to crow every sixteenth note.

I would probably add a norns parameter per crow output for its slew time, and not (yet?) have them controllable from the inside of PHONOTYPE. Either that, or we might want a CROW.VS= 1 SN K 0.3 alternate which allows you to specify slew, and the original one always has a slew of 0.

I am also interested (maybe in a later PR) in CROW.ACT <output> <trigger>, which will fire the action for that output, and then have a corresponding set of parameters in Norns to set crow actions (choose between trigger and AR envelope) and length.

You will want something like

var iargs = PTOp.instantiateAll(args); // this "instantiates" all the children for you.
SendReply.kr(args[1], "/crow/out", values: [iargs[0], iargs[2], 0]);
^Latch.kr(iargs[2], iargs[1]) // Just output the sample-and-hold.

[sixolet]

Probably draw your min and max from the input signal.

Here is where you want to replace Impulse.kr(0) with another argument. I suggest the first arg (args[0]) be the trigger, and shift everything else up one.
