you need to be careful that it doesnt silently call malloc

i would normally advise against using it.

Does anyone have any experience with speed of traversal through a
boost multi index container? I'm pondering their use to manage notes
currently in play, eg indexed by midi channel ordered by midi event
time/frame stamp.

Not sure - possibly the main reason for the post was to seek help in resolving

All up, serious food for thought and very much appreciated!

the amount of initialization code per note is still a
real limiting factor on how busy things can get before it all falls apart.
Such is life (for my friend).

I remember seeing some connection weirdness when I tested with pyjacksm,
but Torben said that's already fixed in another branch. It's called
bpjack. I am currently unable to build it due to boost naming weirdness,
but depending on your distro

I'm not asking for in depth debugging/analysis support here (I'll figure it out
eventually!) but I'm hopeful someone might have an 'off the top of the head'
suggestion.

I am surprised that nobody so far has suggested using the key and

If you don't mind, how would one go about salting it?

Thus, if you repeat the note with identical velocity... you'll always
get the same random-number sequence.
or do you just get a segfault :-) ?

Wow
reliably re-create a pseudo random sequence, in general I would
not want repeated identically created notes to sound exactly the same.
Agreed... but apparently cal /does/ want that. :-)
Not quite. Over the last 12 months I've learned that I don't know enough

lead to jack reporting a change to samplerate/buffersize on the fly?
