i'm having a problem with gcanvas. i use a reset-message to clear it and from time to time it just won't empty. it's not crashed as it still works, you can draw in it. but won't empty. restarting the patch fixes the problem.

anyone having the same problem?

osx 10.6.8 / pd-ext 0.42.5

as i acquired ableton live a while ago i became interested in max 4 live as a possible alternative to pd.

i'm quite happy with pd, don't get me wrong, but as i mostly work with sample buffers, some of the pd-extended's problems with GUI vs. sound engine can be a problem (so far i've managed to work around them, thought)

so i tried the M4L-demo and immediately the excitement started to fade. the "stereo in/stereo out and that's all folks"-limitation for max-app was the first drawback as i've just started to play with surround sound. i know it's possible to run multiple max-apps on different channels and achieve surround that way but i couldn't find information whatever it's possible to share audio btw max-apps. propably not. actually, i couldn't even solve whatever it's possible to run audio AND midi to one max-app as there's a separate instrument for audio and midi channels.

so it seems M4L is more intended to be an audio/midi instrument/effect with emphasis on using the live side than the other way around.

i really could make use of some max/msp:s advanced sample buffers and gui-candy but otherwise the change from pd -> M4L seemed to introduce more problems than solve old ones..

maybe buying the full max/msp? i don't know. 400usd for a couple of extra modules is not exactly cheap.. and iLok is something i wouldn't like to get into..

so at the time i just continued using pd. it's something that i know my way around and i like this community.

any thoughts?

i'm making an installation piece and using readanysf~ to playback some files. i've used it in the past and found it very reliable. but now it seems that triggering playback on six of them at the same time crashes pd. not constantly (weirdly enough) but too often anyway.

i'll propably stick to normal readsf~ for this time, i only needed readanysf~ to slightly manipulate the playback speed, but has anyone else bumped into this problem?

it's osx 10.6.8, pd-ext 0.42.5. i'm using a big audio buffer (200ms) cause there's no real-time processing (= no latency issues) and i want to make it as solid as possible.

here's 4 tracks i made with my new-ish pd-sampler, using old 7" vinyls as source media. mixed and played straight to 2-track stereo. /w some mastering done in reaper.

the sampler has 4 buffers capable of instant record and replay. dsp-side is simple, filters, reverb, delay, sample playback speed. yawn. the thing is mostly about instant control and controlled randomization. almost everything can be modulated in some way.

the samplers also have multiple voices /w variable speeds and loop lenghts. so the sample can be played back in for example 0.5, 0.75, 1 and 1.5 speed. like organ registers, in a way.

here's also a live recording of a set i did on a festival last year using an earlier version of the sampler. here i'm using only vocal recordings from a concert prior to my set.

i'm having problems with the good ol' freeverb~. the problem is, with couple of my patches the cpu usage suddenly goes throught the roof. like after running the patch for 5-30minutes. i finally narrowed it down to freeverb~ freaking out. i switched to similar reverb in hardoff's DIY-package but still wonder what's the problem...

i'm on osx 10.6.6, pd-ext 0.42.5, intel macbook. fiddling with the buffer size doesn't seem to make any difference.

is it possible to read the size of an audio file without soundfiler? i'm using readsf~ to play wav-files and it would nice to see how long the file is...

of course i can read the file also to soundfiler, and get this info, but that means i have to read it to an array (a BIG one, in this case) and that freezes everything for a split second, as we know..

been using the +bubbler a lot. excellent stuff.

not 100% sure about 10.8 but at least on 10.6 it's possible to make a "virtual" soundcard (ie. multiple soundcards show up as one in audio programs) using aggregate device on the audio/midi control panel.

using multiple cards this way may cause issues with audio sync - for example - but it's definately worth a try.

great update. my main patch can now use 25-50% smaller latency with the same cpu usage.

I'm currently using readanysf~ to implement a player that plays sound from movies (avi files mainly) but I found it makes really awful glitches when trying to play the file from random positions. I use "pcm_seek $1" messages for the later.

i've only managed to play 16bit wav files reliably...

i use [pvoc~] on a new project and ran into a strange bug (?). i record into an array and then use pvoc~ to play the array. pd crashed every time i tried to record to the array. i found out that if you assign the pvoc to play a certain array only _after_ you have recorded the sample (via "setarray xxxx"-message) it works just fine. strangely enough, it works just fine after that (the first recording). i can resize the array, record into it. no problem. weird.

osx 10.6.8 / pd-ext 0.42.5

tried to use an array as an alternative, but it uses more cpu.

damn. is there any alternative? i only need to draw a simple waveform in with pixels.

as far as i know, kemper uses dynamic convolution, taking a sample for each frequency on different volumes, thus mimicking the distortion/coloration of the amp.

i've used this logitech ps2-like model with great success.

i had a problem there the cpu usage went through the roof after some minutes then there was a freeverb-object present. maelstorm pointed out that there's a bug (causing that) but you can avoid it by sending very quiet noise to the freeverb-obj. could it be the same bug?

i use this:
[noise~]->[*~ 1e-09]->[freeverb~]

ok. thanks!

yes. just sen a message with two values straight to [noteout]

for example [0 62] to noteout sets the first pad to full yellow. [0 0] turns it off.

a 12" powerbook G4 / 1.5Ghz / 1.25GB. osx 10.4.9.

works like a charm, lower latencies seem to be a problem now and then for the cpu. planning to buy a used intel macbook.

also use a m-audio 1814 audiocard, a little funky (the only non-hotswappable fw-audiocard???) but gets the things done. mostly use the novation launchpad for controller (a blast to use with pd).
