waveform~ in poly~ instance

April 2, 2010 | 4:10 pm

my poly~ patcher contains a buffer~, record~, and waveform~.
I am using thispoly~ to get the poly instance and name my buffer~, record into my buffer~ and display my buffer~ (using waveform~)

i can name my buffer~ so that each buffer in each poly~ instance has has its unique name using:
thispoly~ –> sprintf (set MF%ld)
so that the buffer~ in instance 1 is called MF1, the buffer~ in instance 2 is called MF2 etc.

I can record into the buffer~ using record. and can then double click on the buffer~ or record~ object to view what has been recorded into each specific buffer~

However waveform~, will not display the waveform. i have tried sending it the same message using the same principle as above:
set MF1, set MF2 etc.
and have also tried the message:
set MF1 1, MF2 1.
ie display channel one of buffer~ (they are mono buffers~)
however nothing will display.

Can anyone answer the question?
ive included the folders

Cheers
Paul

Hello Paul,

I do not have any IO connected to my computer so i can’t test it but this should work i guess. If not i’m affraid you’ll have to wait for the Max-gods to respond. :)

ye cant see any reason why it wouldnt work either.

the waveform~ for some reason doesnt know to link to the buffer~.

Did you copy the updated code into your patch? Because i think it should work now. You forgot to put "name $1" before the waveform therefore it doesn’t understand what information it’s getting from the receive.

weird, it worked the first time a did it, but then stopped working after that. Even weirder considering that according to the manual sending the message ‘name’ followed by a symbol specifies what audiofile the waveform~ should link to rather than which buffer~ it should link to. The message ‘set’, which is what i originally used, followed by a symbol links the waveform to that buffer~.

any ideas? ill keep playing with it

You’re right, my bad. :) Indeed it should be "set $1". Just change the "name$1" to "set$1" and you should be alright. It’s weird it worked the first time though…

but thats what i had in the first place no? i have
thispoly~ —-> sprintf set MF%ld —–> waveform~

the same message is also going buffer~ and record~. it manages to name, so the message going to those objects works. but when i send the same message to waveform~ it doesnt link to those objects.

i also tried using the attribute namebuffer but didnt work either.

No, just look at the output of the receive object connected to the waveform, somehow it doesn’t ouput the "set MF1(or whatever)". Instead it just outputs "MF1" Just try connecting it. I go to sleep now…
