since some weeks, I am learning and practicing how gen~ routine works and how to program with it. Yesterday, I was assembling a delay line, that is a kind of tapin~ tapout~ decomposition using a recirculating buffer, and I was thinking to save it as an abstraction in order to recall it in other patchers if needed. I know that in Max/MSP the abstractions allow to use replaceable arguments in order to create multiple different instances of the same abstraction: for instance, if I have a BUFFER abstraction which includes a buffer~ 1024 #1 object, recalling BUFFER array_1 the result inside the abstraction should be buffer~ 1024 array_1. I was wondering whether this is possible also with the gen~ abstractions or not. If not, how can I control text arguments like, for instance, the name of a buffer inside gen~ from outside? I actually considered also the param/setparam objects but they seems to route only numerical values, as the gen~ routine computes only 64-bit numbers at sample rate, doesn't it?

Waiting for your replies, I thak you in advance.

Hello all,

Maybe some variation on this example? (E.g., change ''flimflamfoo" to "#1_flimflamfoo".)

Is it also possible to change the length of the buffer linked to the buffer or data objects inside the gen~ patcher from outside? I mean, for instance if I have a data BUFFERNAME 32768 object inside a .gendsp file, can I change the latter parameter from outside when I recall the mentioned abstraction in a Max/MSP patcher?

I'm sorry for the double post but I'd like to renew this topic if possible instead of creating a new one, considering that the main subject of both questions is almost the same.

The difference between 'data' and 'buffer' objects in gen~ is simply that: 'data' is fixed from within gen~ while 'buffer' can be modified from outside. So a simple mod to Christopher Dobrian's patch shows how size changes to buffer~ objects outside of gen~ automatically update the referenced 'buffer' object within gen~:

(or put another way, in reference to your question: "if I have a data BUFFERNAME 32768 object inside a .gendsp file..." change the 'data' object to 'buffer BUFFERNAME 32768' and the latter parameter is changed from outside whenever the size of the outer buffer~ object is changed in size)

Hope that makes sense.
