funny that it doesnt work in windows; normally such .zip

Folder and file names starting with ._ are typically an attempt to 

store Classic Mac OS resources in a .ZIP archive.

IOW, you can't use this stuff on Windows anyway.

okay! good to know. So it's OSX, OS9 and XP compatible. That's nice.

I'll have to update the help and maybe look over the mapping. but, 

for now it works like this: 0 is very far away, 127 is very close. It 

should not be silent between 0 and 100 and it's not with my comp.

ooops,

for now it works like this: 0 is very far away, 127 is very close. It

Well, it'll probably just stay a abstraction since I've never made a  
binary (very little c experience).
Users will probably often want it in a slightly different flavour, so  
an abstraction in ok for that. I can imagine one would like audio- 
signal input for the parameters as well.

Well, I first had foldernames like 'put in folder ./Cycling '74/ 

externals/' which, according to Mathieu's reply where converted in XP 

to 'put in folder ._Cycling '74_externals_' (/ replaced by _ so it 

seems). With the second try I simply changed the folder name to 

'ep_binSpat-object' which works okay, so it seems. Also, a folder 

named 'ep.binSpat~ 0.12' seems not to cause problems in XP. As I said 

before, I archived all (files and folderstructure) to a single .zip 

file in OSX 10.4.4. It seems to work in OSX, OS9 and XP.

I don't know about all the Mac OS idiosyncracies, so guess it also 

You can ofcourse download the .zip file to see it's structure.

it's not a compression format, it's a standardized device-image format.

typically one would use the same line~ for this and 

eventually releated effects; say, doppler, volume, filter

all have the same parameter interpolation setting.

and i also think the line~ stuff for the
parametrs does not belong in there.

Yeah, but I live in Macland, so I don't have the XP problems. I can 

take your original zip over to an XP box, but that still doesn't tell

sounds interresting / suitable, although I'd like not to be dependent 

on 3rd party externals. But, I can not find it online. 

laut8leise.de/aso.html should have it, but there's a broken link... 

Can anybody send me a copy off-list? thanks.
