Re: [PD] Phasor Driven Midi File Playback?
by saint 12 Feb '08

12 Feb '08

thanks for the quick reply again martin, it's a strange problem that i seem to be having. because i definitely have all the midifiles in the same folder as the patch but [midifile test.mid] ...or... [read test.mid(---[midifile] gives... 'error: midifile: unable to open test.mid' but when i do [bang]---[openpanel]---[read $1(---[midifile] and point it to 'test.mid' it seems to work? hmmmm... unfortunately for what i want to do i need to be able to automate opening different midifiles. i'm using your zip from http://puredata.info/Members/martinrp/midifile/midifile.zip/view thanks again in advance! ----- Original Message ---- From: Martin Peach <martin.peach(a)sympatico.ca> To: saintidle(a)yahoo.com; pd-list(a)iem.at Sent: Tuesday, 12 February, 2008 5:13:00 PM Subject: Re: [PD] Phasor Driven Midi File Playback? saint wrote: > >hi martin, > >been trying your midifile object and it's working nicely. great! > >is there a way to send it a [read test.mid{ message or a [read >folder/test.mid{ message? > >i need to automate opening a bunch of files without using the 'openpanel' >object. > Just like that. Or send a message or symbol containing the path to the [read $1( message. It's probably easier if all the files are in the same directory as the patch.

microphone feedback canceling
by tim 12 Feb '08

12 Feb '08

Hi, I'm planning to use a microphone on stage, with pd. With it comes the risk of unwanted feedback. Has anyone done a feedback canceling patch or seen a proven technique ? I don't know much about how this works in commercial devices (and if they really work for that matter), but I suppose it's done by detecting a frequency that peaks and apply a filter on that... Tim

gemmouse wish
by marius schebella 12 Feb '08

12 Feb '08

Hi, it would be very helpful to change the behaviour of gemmouse a little bit (to get similar results to the translation of objects in the gemwindow). [gemmouse 8] should normalize to the height (like gemwin) and not to the width. given a rectangular gemwin any aspect ratio (no difference between 2:1 and 1:2...) always normalizes to the height and sets (with the default view) the top and bottom borders to +4 and -4 gemmouse 8 on the other hand normalizes to the width. this makes it very difficult (unpossible?) to build mouse interaction with variable window sizes. another feature wish: to be able to tell the dimensions of the gemwin. esp. after resizing by mousedrawing. thanks, marius.

hi martin, been trying your midifile object and it's working nicely. is there a way to send it a [read test.mid{ message or a [read folder/test.mid{ message? i need to automate opening a bunch of files without using the 'openpanel' object. cheers again, john. ----- Original Message ---- From: Martin Peach <martin.peach(a)sympatico.ca> To: saintidle(a)yahoo.com; pd-list(a)iem.at Sent: Monday, 11 February, 2008 8:19:56 PM Subject: RE: [PD] Phasor Driven Midi File Playback? saint wrote: > >I've been trying to incorporate synched looped midi file playback into a >system of tabread looping players.

You feed it ticks from a [metro] to advance through the file and can jump to any tick in the file. It can also dump the file so you can find the tick number to go to. It doesn't know about seconds but you can tune the speed very finely. I have had it running in sync with the Hydrogen drum machine for hours at a time.

0.40.1 look (fonts) in 0.41? Is it possible
by matteo sisti sette 12 Feb '08

12 Feb '08

Hi, As I mentioned in an earlier unrelated message, I have just upgraded to 0.41 and it seems it fixes some critical bugs that made my life a hell. Now, something has changed in how GUI texts look like. Probably it's just the font that is being used, I don't know if some more aspects are involved (spacings, sizes...). I make extensive use of GUI, and now my patches made with 0.40.1 look horrible. Is there any way in WINDOWS to configure PD to use the same font that was used by default in 0.40.1? Will it be enough to have the gui look the same as it before? I attach two screenshots of the same piece of GUI as it looked in 0.40 and as it looks now in 0.41. Tastes are personal, but I don't really think anybody can honestly tell it looks better in the new version... -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

smoothing control signals
by matthew venn 12 Feb '08

12 Feb '08

Hi list, I'm a beginner with PD, and I'm finding it useful and frustrating in equal amounts! Right now I'm looking at ways to smooth control signals. I wanted a control version of [lop~]. I couldn't find anything in the docs, archives or the wiki. In the end I made the attached abstraction using [lop~] and [snapshot~]. I wonder if this is inefficient? Now all my patches need to have 'compute audio' turned on. I'm sure I must have missed an obvious external or patch somewhere, as it seems to me like quite a useful function. Thanks, Matthew

pd becomes unresponsive but does not eat cpu
by matteo sisti sette 12 Feb '08

12 Feb '08

Hi, Does anyone know what kind of errors may cause PD to become completely unresponsive (i.e.: you click on any GUI object and nothing happens, ctrl+e does not change cursor, clicking on any object doesn't open it, pd's window won't close, etc) but without consuming any CPU at all (0%)??? It's something triggered by something in my patch, but as usual I am not able to isolate it, as all tests with small quantities of things always worked and never had any error, and just when things get bigger (only a matter of quantity: more instances of the very same things) something weird happens.... Windows XP here. What if a message tree becomes HUGE not in depth (which would give a stack overflow) but in "breadth"? A part from the time needed to execute it (if that was the problem, pd would hang consuming a lot of cpu), is it possible that it gets just too big and everything breaks and stop working without triggering a stack overflow or whatever error? Or must it be something else? Thanks, m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

kraftpad/ddr_pad patch
by Noah Walcutt 12 Feb '08

12 Feb '08

This is my first PD project, thanks to Dave Merrill for the starter patch and inspiration. *If this patch already exists online please refer me to where I can find it.* 1) Here is what I'm trying to do: --Create a patch for Dave Merrill's "DDR-style musical instrument.<http://www.instructables.com/id/DDR-style-musical-instrument/>" that will play notes from the cmajor scale when certain pads on the assembly are depressed. --Dave has already created a patch that interprets signals from the pad --I am trying to assign these (eight) signals to different oscillators so that when a pad is stepped is on one oscillator plays at a time. 2) Here are the issues I'm having: --all of the oscillators output continuously when I turn the audio on --not all of the inlets in cmajorscale_phasor.pd appear to be working in my subpatch (ie I step on a pad and only 4 of the inlets show they have recieved a float) 3) Attached is a patch of what I've come up with so far, as well as the other patches written by Dave Merrill. Any help would be most appreciated! Thanks, Noah

pd-extended box colors semi transparent
by marius schebella 12 Feb '08

12 Feb '08

hi hans, does tcl/tk support transperency? is it possible to make the backgroundcolor of the objectboxes semitransparent? esp. in a case like this: [bang] | [bang] | [bang] you cannot tell if the middle bang is connected or not. also sometimes you could hide parts of objects, and I would rather like to have a transparent behaviour. marius.
