denormals: svf, freeverb (was Re: bug in freeverb???)
by Ed Kelly 14 Aug '09

14 Aug '09

We have to sort this out! The denormals bug in freeverb~ _seems_ to have been fixed by following Julius' advice. I made a makefile with -fno-trapping-math as a flag and so far so good. I haven't had a problem with the freeverb~ object pegging the CPU. May I advise that this is implemented in PD-extended, since it causes my patch to NOT WORK AT GIGS! I simply cannot take any more embarrassment. I want to play live, otherwise there's simply no point doing anything! The second one I have discovered is in bsaylor/svf~ and there's no makefile for this in the subversion repository. I notice in the source code there is a FLUSH_TO_ZERO definition. Interestingly, when I try to compile this external using a bog-standard makefile on Ubuntu 8.10, it causes an error: cc1: warnings being treated as errors svf~.c: In function ‘run_svf’: svf~.c:59: error: dereferencing type-punned pointer will break strict-aliasing rules svf~.c:60: error: dereferencing type-punned pointer will break strict-aliasing rules Now, I'm trying to unpick the statement: #define FLUSH_TO_ZERO(fv) (((*(unsigned int*)&(fv))&0x7f800000)==0)?0.0f:(fv) which is being called on lines 59 and 60 of bsaylor/svf~.c, causing the compiler to choke, and (perhaps) causing my drumsynths to break! And by the way, where is the source code for the _other_ svf~ external?

control your Mackie C4 via OSC with contrOSC
by Malte Steiner 14 Aug '09

14 Aug '09

Hello, I released a new free open source application under GPL3 for Linux: contrOSC is a middleware to bridge hardware DAW midicontrollers to OSC (Open Sound Control) enabled software like PD, CSound or SuperCollider, so you can easily create patches which communicates with the devices. The first one is the C4 by MACKIE (tm). Demopatches for PD and CSound are included, the OSC commands are documented in the manual PDF. http://controsc.sourceforge.net Dependencies are - QT 4.x - liblo for OSC - alsaseq for Midi So far only sourcecode release. Cheers, Malte -- ---- media art + development http://www.block4.com

Pd Floss Book
by João Pais 14 Aug '09

14 Aug '09

Hi, after being quite busy for a while, I have some time now for some small stuff. What's the state of this book? I just browsed, and it seems to be in the same state as some months ago. I still should look at my messages chapter, anything else?

sustain pedal abstraction
by Amos Robinson 13 Aug '09

13 Aug '09

Hi guys, Just in case you're interested, I wanted to use my sustain pedal in Pd, so wrote these abstractions: sustain, with three inputs: note, velocity, pedal (nonzero for sustain, zero for no effect) dam, with two inputs: a list value, and flow bool. I guess when flow is 0 it's like a [pipe 1e999], and flow set to 1 it flushes. I thought of doing it that way but felt that using lists would be better. I think after actually implementing it though I've changed my mind. Question: is there a simpler way than these that I'm missing? Thanks, Amos Robinson

Re: [PD] how to find [r $-0_anyname]
by Ingo Scherzinger 13 Aug '09

13 Aug '09

The version is the problem. The new windows version seems to have a bug with "find" in general. I posted that in another thread. And any older version (0.40.3 or 0.41.4) can't find it. So I guess I'll have to wait until the latest windows version will get fixed. I posted a bug report already. I was just hoping there was a possibility in older versions until the new one gets fixed.

Errors building PD from source
by Ian Andrews 13 Aug '09

13 Aug '09

Hi All, I'm trying to build Pd-0.42-5 on Mac OSX 10.5.5 intel (tk/tcl8.5.7) It compiles ok but when I go to make it gives the following errors: /SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc -Wno-error -O2 -o ../bin/pd-watchdog s_watchdog.c ld: library not found for -lcrt1.10.5.o ld: library not found for -lcrt1.10.5.o collect2: ld returned 1 exit status collect2: ld returned 1 exit status lipo: can't open input file: /var/folders/JJ/JJlSAMjyENGNhM-Li9ZWvE++ +TI/-Tmp-//ccl7yaI2.out (No such file or directory) make: *** [../bin/pd-watchdog] Error 1 As far as I can see from the man file ld searches first in /usr/lib. In /usr/lib there is a file called crt1.10.5.o Anyone know what's going on? I have also tried compiling Pd-0.41.4-extended but contrary to the install instructions there is no configure file in the src directory , just configure.in. Not quite sure how to proceed here. Before anyone says 'why not use the binary' I'm building from source because I want to be able to start up PD from a shell script with various flags. IOW I need PD to start up and load a patch, set the correct output device, etc. automatically and reliably. Its for a gallery installation. Any suggestion of alternative strategies would be welcome. I'm fairly new to pd but I have been building from source on Macosx and linux for a few years. Usually I can work it out. This time I'm really stuck. ian
