how come when i do this

if you put a [print] after [openpanel], you'll see:

print: symbol /music/samples/bird songs/tui call.wav

i can point it at /music/samples/bird songs/tui call.wav and it will load fine,

but if i do this

[bang( | [/music/samples/bird songs/tui call.wav(

if you put a print here, you'll see:

print: /music/samples/bird songs/tui call.wav

wich is not the same as the output from above.

i'll try to explain, what happens here in my own words, though i don't know the inner coherences of pd.

normally, a white space is used as a delimiter in pd, that means, pd can separate the different elements of a message by white spaces. a 'symbol'-message is only able to hold one element. any further elements are omitted. so if you try that:

[one two( | [symbol]

you'll get 'symbol one'. also, if you do:

[symbol one two( <- message box | [print]

it will only print 'symbol one'.

now, you'll certainly ask: 'but why does [openpanel] give me symbol-messages, that can ontain spaces?'

the answer is: i don't know. i think, this 'feature' was introduced some time ago to allow spaces in pathes. i know, that is possible to have spaces in symbols, but it needs 'special' ways to make them. there is for example the [list2symbol] from the zexy library, with that you can create them:

[list one two( | [l2s]

gives you 'symbol one two'

but if you send such a symbol over tcp-connection, e.g. [netsend]/[netreceive], the message gets converted into a two element message.

this all sounds all very confusing and it took me quite some time to figure all details out. that's why i recommend to avoid spaces, whereever possible, when working with pd.

roman

[symbol] | [read -resize $1 sample( | [soundfiler]

it doesn't work (says 'can't file file /music/samples/bird')?
