hi,

does anyone have any ideas why pix_imageInPlace might not be working for me? i'm just using it's help-file patch, and it is definately loading some images successfully (according to the console), but it just displays a blank white square..

this is annoying because pix_multiImage works fine but it is too slow when it moves between images so i really need to use px_imageInPlace.

i cant work out why there's a nasty amount of latency in pd which i dont get at all in cubase. i've noticed that whenever i start pd, the buffer size on my soundcard control panel gets set to 2048 no matter what it was set to before. is that anything to do with it?

anyone else had problems getting asio stuff to work properly in pd?

1. is there an easy way to use keyboard input? once you've made a GEM window fullscreen you obviously cant click on messages to send them so cant destroy the window etc.

2. the GEM tutorial i've got mentions pix-draw and says that it is very slow, but i want to make something entirely 2d, just based around drawing different images to different parts of the screen. is GEM the wrong package to use for this?

i cant find it, it says here:
http://www.junklight.com/pd/
that it is available in the externals here:
http://pure-data.sourceforge.net/
but it doesnt seem to be in the externals zip file... any ideas?

with simple things like this i cant help but think things are much easier to program in c rather than thinking in terms of signal processing...

is there an easy way of getting the average? bearnig in mind i might want to change the array size later so i want to avoid a big chain of additions followed by a division.

hello. i need to change the block size in my patch for a better resolution fft, but when i send block~ a message like "set 2048 1", suddenly no audio comes out (dac~ stops working?). It seems like everything up to the dac~ is still being processed ok. if i send a message to block~ setting it back to 64, then sound comes out again. any ideas? thanks.

try pressing all the keys at once (it has to be all at exactly the same time though)

> What driver do you use ?

i use the one that came with my m-audio firewire audiophile, maybe i should have a look round for an update or something?

> The delay setting you speak of is a buffer size

i guessed this was the case but couldnt understand why it makes you specify it in ms. it should just give the usual options of powers of 2 etc. the delay in ms will give different values of buffer size depending on the samplerate won't it? maybe the distortion was due to the aliasing like you say, i'll try 25 and 15 etc, cheers for the advice.

sound preferences? is that the same thing as audio settings? it has an option for delay, but if i set it to something below 70ms then it starts distorting horribly, as if its not using the asio drivers or something.

a blur can be described by a convolution i would have thought. [pix_convolve] will do it maybe.

grill library?

is it not available anywhere?...

ooh, i was wondering how to use initialisation arguments in abstractions - i just read the bit in the manual on dallar signs and see now that thats the way to do it.

yeah, i shouldnt have any trouble making those changes, thanks.

wow, that works great. cheers.

the trouble with adding and then dividing was that i couldnt think of a way of doing it so that th number of points in the array could change without having to alter the sub patch or abstraction or whatever.

that patch looks great, thanks very much. there's a few objects there that i didnt know about which are quite fundamental like until (i'm still fairly new to pd). thanks again.

i think the answer lies in using spigot. i'll try playing with that.

that works great, thanks again.

the only problem now is that there is more than one line of output from each pique operation - i.e. if i print then i get something like this:
print: 0 2006.24 1.00113 -0.666607 0.746927
print: 1 4995.52 0.998992 0.812561 -0.581145

using unpack, im only getting the second line of values..

aah.. i see, thanks.

one other quick newbie thing... i'm using the pique object which only has 1 outlet but apparantly outputs a list of various bits of information - how do i access each of these things individually? (to actually do things with them)?
