@Fauveboy Yes, you can use [abstraction 1], [abstraction 2] to distinguish different abstractions. And if you are very confident that you will never open up two instances of your patch at the same time, this would be enough. But if you open up two instances somewhere in the future, they will interfere with each other, if you have something like [send $1-something] inside the abstraction.

i use $0 all the time just to be sure and don't have to worry, but it is up to you. i would for example use [abstraction $0 1], [abstraction $0 2], if the abstractions would need to communicate with the main patch or each other. The important thing here is that every send, receive, text, array and struct get some $0, but this is only if you maybe open two instances at any time at once.

The other thing is that $-arguments in objects and messages work completely differently. As @whale-av just described while i am typing...

heres the patch in a zip file. im looking over it myself again after reading your messages just now. the $0-table is in the sub patch pd load.sample in the gridSampleptest abstraction grid 2.zip

grid200617.zip

just the lastest version of the patch here

it Works!

...is what to have a list of abstractions instead of copy and paste?....a bit like in c programming you can have an array and a for loop ?

@Fauveboy Usually just copy&paste. You can also create objects with dynamic patching, see https://forum.pdpatchrepo.info/topic/10813/collection-of-pd-internal-messages-dynamic-patching.

Also look at the [clone] object, which might be what you are looking for.

@Fauveboy Well that is good news...... having twisted my head right off my neck I thought this might work...... twisted.zip
but as you have it solved...... well done!

A Eureka moment in all that?

Yes....... abstraction = sub-routine (in 1970's speak).......

@ingox I dont see see anything appearing as clone object?

@Fauveboy apparently [clone] is not present in pd extended...

@Maelstorm Hi there, I came across this post today as I've just started using PD recently and polyphony has become a bit of a struggle. For that reason your patch was great one sense but it does pose some new challenges.
How does one add ADSR functions to all the voices at once? Or even how does one select different waveshapes? I can build monophonic versions of both of these but once I get to polyphony, I hit a wall.

@matchboxyouth i would take a look at the help file from the clone object, it works well together with poly and with the "all" message you can send something to all instances. but it also works without clone, like in the poly synth example in 7.stuff/synth.

@Jona Thanks very much, will have a look now!

Just one other thing there, where can I find this 7.stuff/synth?

@matchboxyouth It's in thePd documentation...... along with loads of useful tutorials.....
Pd/doc/7.stuff/synth
