Re: [PD] About extending the Universal Polyphonic Player
Hi Thomas, Thank you for your answer, it's been helpful! Now I'd like to figure out how to modify the message in order to be able to select from it with a [route] object. Thanks! jl On Mon, Mar 30, 2015 at 12:25 PM, Thomas Grill g...@g.org wrote: Hi Jose, I found the Polyphonic Universal Player [1], I really liked it, and I would like to ask you about it. - I would like to build a simple classic synthesizer, that you can change its waveform, filter and envelope parameters. How could I send these parameters to my voice? In the patch '4-noteoff.pd', I understand that you send the ADSR parameters with a list that you call tag, is it possible to create a tag thus I can use the object [route] to get each different parameter from it? Do you have an example of a similar simple synthesizer? There are three different ways of controlling the synthesis voices: (see http://g.org/research/software/upp/upp-tut4/) - at creation time, through object creation arguments (to upp.flow or upp.xc/upp.x2/upp.xf after your synthesis patch): Use this for fixed parameters that never change for different events. - at invocation time, that is, when you start the individual event. ADSR-curves would be an example. The list that goes to the left inlet of upp.flow/upp.xc/upp.x2/upp.xf starts the event. The first list element is called „tag“, it identifies the event. It should be unique for polyphonic events, e.g. a key number, but it can also be a running index - at run time, when the event is already active. You can use the right inlet of upp.flow/upp.xc/upp.x2/upp.xf to send a message to the event. The first atom of this message is again the „tag“, so that the event can be found. The rest of this message is your choice, it can be used to stop the event, or to change parameters. - I do not understand how the subpatch [spat mono] works, could you explain it? spat_mono is one of a couple of spatialization abstractions - there are also spat_stereo, spat_quad, spat_varbus etc. to route your monophonic voice to different busses/loudspeakers. spat_mono itself does hardly anything, it is just a container for your synthesis abstraction. It routes the audio output of your synthesis abstraction to a bus defined by the first creation argument $1. The rest of the creation arguments are used the instantiate your synthesis abstraction. $2 is its name, $3 etc. are creation arguments. i hope that helps, best, Thomas ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] How to navigate a long sound file in vanilla PD
(Disclaimer this is geared more towards iOS) I would use the CoreAudio framework to decompress files read from disk in chunks into a defined buffer in your Pd patch. And then create a transport control system for managing playback and updating of your internal buffer. In my opinion this would be a fair bit of work to implement. Maybe there are other ways to do it, but I wouldn't say the task is simple.

I am intermediate PD programmer, about 9 months into patching. I really love PD, despite some quirks. The single most annoying issue I have found so far is the inability for PD to accurately index into large arrays. The way this manifests is very curious! I first noticed high frequency noise at maybe 6 min. into an array, which gets worse as you move into the file. At 20 min, it's really horrible. I would say the root cause is a) lack of a long integer datatype. Friends, sometimes you really want ints, like accurately indexing into an array, and b) lack of precision in (short) floats. People on the FB group promptly told me this is a well-known issue, and directed me to PD-double. This sounds like a wonderful project, however it seems it is only beta, and breaks several of the modules in extended. So I am wondering 2 things: 1) What solutions have people come up with for accurately reading big arrays at audio rate, using either pd-extended or vanilla? (I have considered breaking the big file up into smaller arrays, but this is cumbersome). 2) What is the long-term goal at solving this problem?

Note that I was only on a laptop so I don't know how relevant this is to your question. Below is the solution I found on the Max forum (I don't have the link right now but it should come up on google). 1- Read the file [silently] from disk (using sfplay~ or equivalent), at 50 times the original speed and record the output into a buffer that is 50 times smaller than the original file. 2- You can navigate through this smaller buffer and multiply the output by 50 to get the correct time pointer into the original file. I then read the original file from the disk, instead of loading it into a buffer. 3- Since I'm making my patch for concert playback, I have put in place a checking mechanism that looks for an existing 'waveform' file. (The patch automatically names these originalFileName.wave.aif.) If it exists, the waveform file is read into the buffer, otherwise, the loaded soundfile is 'analysed'. I can send you my patch if you are interested. I don't see any reason why this can't be implemented in PD. Although the graphical scrolling might be slower in PD. I'd be interested to know if this works in PD.

Re: [PD] wiimote motionplus with low_speed gives always 1 1 1
Thanks for the answer iohannes, actually, libcwiid is considered dead [1], so i think that [wiimote] should be re-implemented (as an abstraction building on [hid]). So, you meant your [wiimote] also dead? but it still works for me, except motionplus. If it totally dead(or will dead), which is best way to use wii remote(+motionplus) on PD and Linux currently? i think it looks fine. AFAIR (but keep in mind that it has been a *long* time), the low_speed message gives you a boolean value (1 or 0), whether the angle_rate values should be interpreted as high-speed or low-speed. since i haven't found any documentation what high-speed vs low-speed actually means in hard numbers, this has been exposed to the patch. I think [wiimote] still works, and if possible, I wanna get the more precised orientation(pitch, roll, yaw) from [wiimote] and motionplus. I have already the orientation from acceleration, but from gyro(motionplus) has better quality. I have to calculate the *angle_rate* and *low_speed* to get the orientation, but I don't know how to get the orientation from motionplus. Could you give me any clew? or any suggest?

Re: [PD] working simultaneously on the same patch from two different places in the universe....
I believe somebody did work on a system that allowed multi-user patch editing. Hopefully someone else on the list has a link. The difficulty is that Pd's code assumes the input is coming from a single user. There's no way for the input methods to differentiate input from separate users. And even if you fixed that, things like dragging array points happen by setting _global_ variables for callbacks. So if you drag on one array while I happen to be dragging on another (or doing anything else for that matter), we'll end up messing with each other's interaction with the patch. -Jonathan On Tuesday, March 31, 2015 6:59 PM, jamal crawford three...@ml1.net wrote: hey list without restarting pd or the patch. theoretical reality or dream? best regs ~/.jc ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
