message priority questions

hi,

concerning the different priority levels of message computing I can’t
get clear with the infos found in the max-documentation:

as far as I understand there are basically 3 priority levels: high
priroity (or schedular-mode), normal and low priority (or queue).

question 1:
is there a difference between high and normal priority when max is not
in overdrive mode?
or the same question differently:
is there any “high priority” if max is not in overdrive mode?

question 2:
it looks like there are 2 ways of adding tasks to the queue when using
“jit.qball”: either replacing the old task (usurp-mode) or adding it
(deferlow).

is there a way of replacing a task in the queue (like “jit.qball” in
usurp-mode does) without using jitter?

any advice is highly appreciated.

best
noid

For your first question you should check out jkc’s very informative
article on this topic:

For your second question:

You might try looking at [qlim 0]. According to the manual it will hold
a message for a specified minimum amount of time, and will allow that
message to be overwritten if it receives another before that amount of
time has passed. To me, this sounds similar to what [jit.qball] does in
usurp mode, but I’m not completely certain of this. Does anybody out
there know for sure?

A somewhat related question about priorities when recalling presets
from pattrstorage:

In my patch I lam loading configurations of subpatchers determined by
presets recalled from pattrstorage in the main patcher. There is the
priorities message to pattrstorage to set the desired order of the
loading sequence. So far so good.

It would be very useful to control this process in more detail e.g.
make sure a subpatcher has been recalled/loaded successfully and then
continue in the sequence. Is there a way to set execution timing
within a preset recall sequence from pattrstorage other then set the
order of parameters being recalled?

Any insights welcome.

thanks
B.
