sssad, bag of tricks and netpd are worth mentioning here too.
i only know little about bag of tricks but its state saving approach is
based on a message box per gop that allows you to save the state of the
abstractions with your patch.
you should have a look at netpd level 3 (in netpd/tutorials), where all
parameters can be saved and loaded in a preset file. basically something
like that:
[symbol savename(
|
| [symbol loadname(
| |
[netpd-x mypatchname]
on top of that i wrote a little abstraction (pad) that handles these
save-load-names for you and allows inter-patch-communication, so
"save-all" does work.
[pad mypatchname]
| \
[netpd-x mypatchname]
in a 2 approach there is one additional preset-manager (P-Admin) that
talks to all (pads) and collects data and writes it to a single file.
(instead of 1 preset per patch). the format here (unlike netpd native
.pst format) is
patchname parametername and-whatever-number-list-or-array-you-have-here
but once you are here you think about more...
- howto morph between presets
- howto reuse some data from abstractions (effects, envelopes, seqs) in
other instances (osc?!)
- howto load presets without clicks (i.e. load data into a table or
dynamically create effects)
as i said, i think it's worth looking at the 3 approaches sssad, bot,
netpd too
hope that helps or inspires.
