Re: [PD] How to avoid choppy midi outputs sounds using multi-user DIY music controllers ? (newbie question)
Thanks again - it turns out that it was a synthesiser problem. In case anyone was wondering, I went back to basics and attempted to play multiple notes through a simple patch. The synth (FM8) appears very much polyphony. However I noticed by chance, the overlapping choppy problem with chords that do not start synchronously (if you know what I mean) occurred with only some of the preprogrammed sounds. So switching to a different sound on the synth solves the problem. - Original Message From: Lorenzo Sutton lsut...@libero.it To: pd-list@iem.at Sent: Tue, 7 December, 2010 16:27:56 Subject: Re: [PD] How to avoid choppy midi outputs sounds using multi-user DIY music controllers ?

Re: [PD] Osc phase and number of periods for subsonic touch-music, (Daniel K.)
Daniel, You could make a table with a sine wave form in it and drive it with a [tabosc4~] object. The only way (as far as I know) to ensure sample accuracy for this is to set the blocksize to 1 (use the [blocksize] object). Otherwise you might run over the end of your table by as much as 63 samples and you will probably get a click (Pd defaults to calculating 64 samples at a time). Hope that helps, David ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] Osc phase and number of periods for subsonic touch-music
Hi, You can reset the phase of an [osc~] by sending a message to its right inlet. In your case the message would be [0.25( , i.e. 1/4 of the way through the cosine wave form, which is zero. That won't work at the note off, though, so the sensible thing would be to use an envelope. But, if you really want precise control of phase instead, write a period of a sine wave to a table (might as well use a long one) and read through it with a [line~] and a [tabread~].If you want 20 Hz, the period in ms is 1000/20 = 50. Let's say the sine table is 4096 samples long and lives in a table: [table sine 4096]. Use [metro 50] to bang a message [0, 4096 50( to [line~] controlling [tabread~ sine]. That way, when you turn on the [metro] it will start at zero, and when you turn it off, [line~] will continue until it reaches the end of the table (which should also be a zero), and then stop.

Hi Robb, http://www.tigoe.net/pcomp/stamp/stamp-midi.shtml is good to look at, considering that MIDI is a serial interface it's pretty segregated in terms of data - scroll down the page until you see the chart. I suspect you are using the [makenote] object which is monophonic. Open the dynamic patching example I send you. It builds the contents of [pd $0-subsub] in [pd-$0-submidimix] to contain 128 [makenote] objects, 1 for each note. I'm thinking of trying to implement this in two dimensions with my [polymap] object, but haven't got round to it yet. Best, Ed Metastudio 4 for Pure Data - coming soon!

I recommend the Hernandez youtube tutorials too. I want to have a good look at Ed's tutorials too. Particularly if the answer to the following query might be found therein :) I am trying to make a musical instrument for two or three people to play at once (fuller details below). Each person will have a controller (just a simple gyro sensor) , and I am outputting to a single software synthesizier. It works fine (some very fun responses so far!) with one controller, but input from the second sensor cuts short the notes played by the first (and vice versa). Is there some way to make a MIDI note play for its full duration regardless or whether another overlapping note is being played ? (and if not, other suggested workarounds most welcome) I thought maybe Noteout channel numbers was the way, but I maybe misunderstanding how these work... I would like to work towards eventually making my own sounds in PD rather than using a preprogrammed synth, but getting this far has been tricky enough for a non-techy like me:) Sorry to spam you with this query.. but I think you did ask for an update :) Many thanks Robb Project Details: I am working towards a remake and electronic update of an earlier, fairly popular dance floor sculpture: http://www.chateau.eclipse.co.uk/robb/socialwhirl.htm but hoping to transform people's movements on the rotating discs into sound (though not expecting to wire up as many as 28 rotating discs for some time!

Re: [PD] lower limit on control to signal
On Wed, 2010-12-08 at 14:33 -0800, Jonathan Wilkes wrote: Hi List, I have a question about converting control messages to signal messages that I thought about after reading a recent thread about triggering sounds made from [osc~]. I recently tried a simple test to see if I could generate audio using a [del] metronome, a counter, and [sin] in a subpatch with [block~ 1]. However, I ended up with a kind of staircase signal that resembles a sine wave, where each step is 64 samples long. Does this mean it's not possible in Pd to convert control messages to audio faster than however long it takes to play a 64-sample block? I (think) I understand why this is true for a normal canvas with the default blocksize 64, but not for the subpatch where I've reset the block size to be smaller. Yeah, it is possible and no, you don't need to adjust the block size of the canvas. Setting the block size can be useful for implementing short audio signal feedbacks and for FFT operations where you sometimes need even bigger block size. The case you describe here is about message to signal conversion which should generally work without adjustments to block size. First, you need a metro that is faster than the 1ms-limited [metro], so your [del] based metro should do. [del] and [metro], both are able to schedule messages in between of blocks, but not all object classes with control inlets and signal outlets take that scheduled timing into account. For instance, [sig~] updates the audio signal only at block boundaries. OTOH, [vline~] uses this timing information to create sub-sample accurate signals (sub-sample accurate means here that a ramp might start and end between samples). I assume, you're now using a [sig~] for the conversion. Try replacing it with a [vline~] and it should do. I am too lazy to test right now, so I hope everything I said is correct.

Re: [PD] new license for pidip and unauthorized WAS: pd-pidip into Debian
Hi Jack!, I was testing proposed by colleagues, and it works, I removed the noise, not yet determined what happens, but it becomes stable, at least the stable axes can provide data, but I keep trying, I've worked with opencv and works without problems, also gridflow is amazing ... Now, the moment I'm testing this and yours Jack, I like plot, but remember the grid view, I have seen in the help or the site of Pd. In work, the grid blue and red dots. What else could be proposed? Best regards José 2010/12/8 Jack j...@rybn.org: Hello, You can use [pix_crop] with [pix_movement]/[pix_movement2] and [pix_blob] to have something similar to [pdp_mgrid].

Re: [PD] Pd-extended 0.42.5 (stable + nightly) tiny fonts?
Thanks Hans, I installed those fonts, removed tcl8.4 (leaving 8.5) and reinstalled pd-extended. No change in font size. I also tried starting pd-extended with the -font-face flags, and still no change. I also switched from the binary on puredata to the pd-extended package in the ubuntu repo, which is version 0.42.5-3. I also confirmed in xfce and in the nvidia settings that my screen dpi is 96, and a 96 pixel wide square is indeed 1in on screen. What else can I try? An interesting note, If I open the 'about PD' patch, and change the font size, 10 and 12 point choices change only the height of the font, the width stays constant between them. Both x and y change for the other font size choices. I can make a screenshot if that helps. I have to say its great to have pd-extended in the repos! and 64 bit! Much has changed. :) Thanks, B.

I also tried yesterdays nightly build. Both versions show object and console text in a super small font. It looks like 8 or 9 point. I thought it may be the dpi setting (since nvidia cards seems to mess with that a bit) but changing the dpi setting in xfce font settings appears to make no difference. Also the object boxes are bigger than needed for the text size. I've attached a screenshot. Thanks, B.

However, it seems that I cannot use pdextended and watch a youtube video at the same time (the youtube vid is a pd tutorial).

When I don't (i.e. start it like this: '/usr/bin/pdextended -alsa' ), I get a bunch of 'device or resource busy' messages in the terminal and I don't get any audio when doing the whold testtone thing). Is there any way around this? well, this is exactly the way how alsa is supposed to work: - only one application can access a (hardware) device at any point pulseaudio is a way to circumvent this limitation. running Pd in pasuspender, effectively disables pulseaudio including all it's features. luckily there are ways around that. - use pulseaudio (not a good option, as Pd currently doesn't support it :-(; btw, pa is geared towards the ordinary consumer multimedia desktop where people would like to watch their youtube videos and at the same time listen to the latest p!nk smash hit; Pd is not really targeted towards that marketm, hence pa is not done yet) - use alsa's dmix interface; dmix is a virtual device that allows several applications to send their audio output to the same hardware device (without the applications even knowing of it). i'm not 100% sure whether you can actually access this from within Pd - use jack. now you can think of jack as pulseaudio for pros, it allows to route the output of one process to the input of another process (or more); process can be both hardware (your soundcard) or software (Pd, your browser,...). there are also ways to make alsa-only applications (e.g. your browser) use a pseudo alsa device that really sends all audio to jack (thus the application need not be aware of jack at all) madt IOhannes I'm new to Pd as well and ran into the ver same problem. After a bit of guesswork, I tried running Pd with the command: pd -alsa -alsaadd dmix which seems to add an unlabelled audio output in the Pd alsa configuration menu. When this output is selected, it solves the problem. I works well enough, but I haven't tried using jack. Can anyone who has used both dmix and jack offer offer an opinion on the pros and cons of each? .Lewis ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list Interestingly enough, I ran into another bug when using Jack and PD. Basically ends up with Jack going non-responsive and any attempt to rid the system of any Jack processes don't really work. All Jack processes simply return a 'defunct' when you look at top. Makes Jack unusable since it will neither start nor stop. The more research I did revealed that this is a bug in the 8.04 Hardy Heron kernel.
