Great!

Well, the return value of the function you hand to (seq ) sets the
time until the next note. This means that you can create a shuffle
using a last line that is something like this;

(if (even? clock) .1 .15)

Clearly you could also end the function with a variable called "beat"
that you might set using a bpm-based function.

Quite so. If you are using the Git version then there is a fix in my
branch called "redacted".
If not you will have to wait for Dave's review of that stuff. On the
plus side; I fixed a lot of bugs like this one (including type-checks
to prevent crashes) and added quite a few types of nodes.
On the down side this is my "teach yourself C++ in one million small
steps" project as well as my "let's try git" attempt so there may be a
issue or two. Those two factors may or may not combine well with
Dave's agenda...

Whoooops! Yes, that would be nice, but I agree with the source that
what we really need is import for scala files. That would immediately
sort out all complaints anyone could ever have about tunings. Would
you be up for that? If not some functions are better than no
functions, I feel.

I'm happy to see another Fluxa user, at this rate of growth we'll be
out of the single digits in no-time! ;¬)

Yours,
Kas.
