Hi Jonny

i have good experience with dynamically created and chained abstraction 
that talk to each other. im using [send], [receive], [send~], [receive~] 
inside the abstractions. i.e. a [notes] abstraction triggers [waveform~] 
and [envelope~] the output goes down to a [delay~] abstraction and so on.

you could receive the commands from flash and use them to dynamically 
create abstractions. give each abstraction an ID as argument. use 
something like:

[addmorefunk id-12]

and inside:

[r $1-r]
|
[r~ dummy-send]
|
[pd addfunk]
|
[s~ $1-s]

now you can tell your abstraction where to listen with the setable 
receive~ i.e. [;id-12-r set id-11-s( would connect/listen to the last 
created abstraction. a [s~ dummy-send] should prevent from
error: receive~ no matching send

see how abstractions can be created dynamically Help/mauals/pd-msg/ or 
[dyn~] in pd-extended. don't forget to send a [loadbang band( to the abs 
after creation. if you need to remove abstractions you have to keep each 
created abs in it's own subpatch to clear it later. see attached patch.

good luck eni
