Re: [PD] displaying a filename
Here's an old patch of mine that does this (as far as I remember! I'm not at home so I don't have Pd working to check). Hope it helps.

Re: [PD] adapting wiimote_navigation_example patch with osculator
Hi have a look at the mapping abstractions they are very useful in this context For the actual point, i usually use autoscale to find out what the range should be, but then expr (if you know exactly how you have to scale is good for adjusting the range. The x-y coordinates might be the other way around in osculator, check carefully (timeline is a good tool to check the OSC data) Luigi Am 07.08.2008 um 01:41 schrieb punchik punchik: hello im trying to use the wiimote_navigation_example patch but since im on macosx, im trying to use osculator instead of the wiimote object for linux.

[PD] physical modelling/general pd - mentor/tuition sought (money offered)
Hi all, I have a 12 month project as part of a masters degree, where I wish to build a physical model of a wind chime. I then want to use the interface to play some of my indeterminate compositions. I was going to attempt it for my undergraduate degree but realised that it was far too complex for the available time that I had then. I have been using pd for a few years now, list lurking, working through basic examples, building simple tools, using other peoples patches etc. But this is too complex for me to do on my own. At my uni there isn't anyone with better skills than me and I don't know of any local fellow patchers. Now as a musician, when I need to up my skills, I will look to find some lessons when I have got as far as I can on my own. So here goes... Is there anyone with an hour a week to spare who can offer some mentoring/tuition for what we can deem to be the 'going rate'. I am more than happy to do this remotely/online, I'm sure there is a way we can work it out. There would be full credit given of course. Pmpd seems like the way to go with this. I have worked through the examples, and, although I have my eye on what examples I would presume to be the best starting points, I'm struggling to get started. The physical modelling is where I first need to start but there's loads of pd stuff I would like to be able to work through with someone, so this could be a (me love you)longtime regular small money earner, if anyone's interested.

Re: [PD] a full-featured sampleplayer
hi all i think there is tons of such abstractions around. anyway, i like to re-implement it again and again everytime i need it, because there is always little things that i would like to have different from the current implementation and also it is always a good exercise (and probably i do better this time than last time). but sorry, i don't have anything at hand, that matches your needs. i only have a recommendation (and i wonder, if others agree on that): i wouldn't make your abstraction [phasor~] based, because of the problem you already sketched out: if you change the rate during the playback, you don't know when it is finished. that is why i propose to make any table based sampleplayer based on [vline~]. since you need to calculate the start-, endpoint and duration, you know at any time, where the index currently is (by calculating the current position from [timer] output and the three values i mentioned above). this way you can change the rate at any time you want, you just need to recalculate start, end and duration for [vline~]. it looks more complicated at the beginning, but it is the cleanest solution i can think of. there is one disadvantage of the [vline~]-approach compared to the [phasor~]: you cannot continuously change the playback speed. so it is yours to decide, which way to go. roman On Thu, 2008-08-07 at 17:39 +0200, Atte André Jensen wrote: Hi I've build a sample player abstraction, and now I just thought of one more feature it needs, and that makes me think I need to redo it again. So here goes: I need a sample player motor that is flexible enough to handle any (most) things I throw at it, at least: * Handles stereo/mono, various sample rates and bit depths transparently. * Allow changing of playback rate during playback * Both lopping and non-looping mode * Optional crossfade looping with configurable crossfade length. First: Is there such a thing outthere already (before I redo it all again)? Second: If not, a thing that I can't figure out is the cross-fade part. I thought about having two phasors, and every SAMPLELENGTH-XFADETIME restarting the idle one, and fading it up in XFADETIME while fading the running one down. Problem is that if the playback rate has changed since last cycle the switch will not be at the end of the running sample. Instead I guess the way to go is to look at the output of phasor~ and from it's output determine when it's time to start the fade, which should occur at (SAMPLELENGTH-XFADETIME)/SAMPLELENGTH. How can I inspect an audiosignal and get bang'ed when it's it reaches some value? I looked at [~], but it seems to output audio, so I guess I can't use that. Or am I totally off in my approach?

[PD] Ultrasonic 'theremin' patch
Hi all, Yesterday I found out that modern audio cards can do much higher sample rates then 48000, which allows for entertaining experiments with ultrasound. I'm not sure if this has been done before, but I'm pretty happy with the results so far. I've created a patch running on a samplerate of 88200 Hz, which sends out high-frequency chirps over two laptop speakers. The chirps are reflected back to the bultin mic using both hands. The reflection is correlated with the outgoing chirps to calculate the time the sound waves needed to return to the mic, thus measuring the distance to the hands or any objects hovering above the laptop. This particular patch just drives two tone generators whose frequencies depend on the measured distances, which are played back over the same speakers as the high-frequency chirps. The result is a two-tone-polyphonic theremin-like instrument. If only I could play this thing in tune... A simple demonstration video and the patch can be found at http://zevv.nl/play/code/ultrasonic-theremin/ This patch just a first test using ultrasound, I'm sure much more interesting things can be done using this technique. The patch is not very well documented at this time, and I think getting things to work needs a fair amount of tweaking for each different setup. Things that need to be setup properly are output level of the soundcard, a magic gain factor after the correlation, and the range that should be inspected for echo peaks to avoid detecing of reflections from the ceiling. I think it would be possible to make the patch do some auto-detection of some of the paremeters like ceiling height and gain factors, which would make a nice addition for future versions.

I want all this into an as good as possible written score. Even this idea may not work at all. Of course, I could do it all manually by recording the raw MIDI messages, printing and transcribing them into score, but it should be easier.
