[OT] Music Notation in linux
by BanjoBob Faraday 05 Mar '12

05 Mar '12

Hey Guys Sorry if this is on the wrong list, but I'm looking for an open source package to prepare some choral sheet music. So far I've found musescore, note edit and lilypond, but I'm not sure if I want to use any of them. Has written any sheet music in linux? Any advice on what to use? Lilypond looks interesting, edited in plain text, then prepares a score as an image. It's a command-line scoring package!!! But I'm not sure if I want to learn to read the text file, which would be needed to write music in it. Anyway, I'm willing to listen to any advice on this. Andrew

pddroidparty netsend and netreceive
by Orm Finnendahl 05 Mar '12

05 Mar '12

Hi, I'm checking out pddroidparty for communication between an android device and a pd patch on another computer. It doesn't seem to be possible to send to or receive any events using the netsend and netreceive objects. I can ping both devices. Establishing a connection and sending numbers from the computer to a numberbox in the android patch gives no errors in the pd window on the computer, but the numbers aren't displayed on the device. The same happens sending data from the android to the computer. I can telnet the port on the android when pddroidparty runs the patch (and get a "connection refused" message if the patch has been closed) so it seems that there is no firewall blocking the communication. Does anybody know about this issue or has anybody successfully established netconnections between pddroidparty and another computer and could give some advice? -- Orm

save search path 0.43 OSX
by Joson Android 03 Mar '12

03 Mar '12

Dear List! i love pd-extended-0.43 !! but i cannot add any search path in the prefferences. It will show my new settings right when i make changes but wont save anything. It prints "ripts/../extra/mapping: no such object" in the pd-window. It works in pd-extended-0.42.5 . Should there be a file where pd saves the path? Where is it? Also, when i make changes in 0.42.5, 0.43 will know about them on next startup. I use OSX10.6.7 and the latest autobuild of xi386 version of 0.43.1-extended. Maybe it is the fault of chaotic me and chaotic computer, so i deleted all old versions of pd, but that didn't help... Johnny

Computer Music with Pd + Tutorial
by Alexandre Torres Porres 03 Mar '12

03 Mar '12

Hey folks, I've taught a few workshops, like Spectral Analysis and Manipulation with Pd in the previous two Conventions. Maybe some of you were there... I've been promising I'd upload a revised version anytime, here it is, my first unofficial pre-release in english: http://sites.google.com/site/porres/ComputerMusicPd.zip I also have a Pd tutorial I did in portuguese that I've translated to english and told this list about it before, there's an update to that: http://sites.google.com/site/porres/Tut-Eng.zip but this is secondary. Well, about these examples, they were design to be highly accessible to novice computer musicians and enthusiasts with no background in computer science and/or engineering. But I do manage to convey rather advanced information and such about a few cool things. I particularly like the section about convolutions/vocoder and phase vocoder. I'd be happy to hear some feedback from you thanks Alex

I had the same problem with Windows XP. Even with the regular MIDI In objects like [notein] or [ctlin], etc. I gave up and switched to Linux.

Pd on ARM devices
by Pierre Massat 01 Mar '12

01 Mar '12

Dear List, I'm planning to buy a Raspberry Pi sometime soon, and I'd like to know the implications of the ARM11 chip on the use of Pd. I know nothing about the differences in architectures, so i'd like to know : - why an ARM chip would be a problem for compiling, installing and running Pd, - if there exists another option that's up to date (Pda seems a bit old), - if Libpd could be used instead (given that i only want to run Pd patches on the Raspberry Pi, I don't need to edit anything on it). Thank you in advance! Cheers! Pierre.

Great Mathieu, I'm finishing the PhD text in the next couple of weeks. then it's time for to get my ass to release these things. what I realized about the pitch-commonality model after my time in montreal is that it can be used in a similar fashion to bren'ts TimbreID Abraço, Marcelo [image: cleardot.gif] abraço Em 11 de fevereiro de 2012 15:13, Marcelo Queiroz <mqz.mqz(a)gmail.com>escreveu: Marcamos às 14h, então!

latest Pd-Extended cpu usage (was: new editing features of Pd-extended 0.43, now in beta)
by Rich E 29 Feb '12

29 Feb '12

Sorry about the double posting (and the first to a totally unrelated post), my send email searching skills are lacking today. Anywho, the latest nightly build is still running at around 17% cpu for me before ever opening a patch. It's just enough to make my fans hum. :) I've attached a process sample from Activity Monitor, hope it helps track it down. Cheers, Rich On Tue, Feb 21, 2012 at 1:16 AM, Rich E <reakinator(a)gmail.com> wrote: > > One thing of concern however is the cpu usage when DSP is on and there are > no patches open - Pd-0.43.1-extended-20120220 reports ~ 17% > while Pd-0.43.1-vanilla reports 7%.
