tbext w/ fftw support
by Tim Blechmann 29 Feb '04

29 Feb '04

hi all, i'm proud to present the first really useful externals for my small library, that mainly contained boring / obsolete stuff: rfftw~ and rifftw~: they are doing exactly the same as the pd-internal rfft~ / rifft~, but since they use the fftw3 library, they are pretty fast: benchmarks on my p4 2.5 GHz for 16 objects: (fftw with sse/sse2 enabled, pd with -O3 -march=pentium4 -mmmx -msse -msse2-mfpmath=sse, gcc 3.3.3) rfft~ rfftw~: block size 64 / overlap 32 65% 32% 128 32 75% 36% 256 32 82% 39% 512 32 90% 43% 1024 32 99% 48% 2048 16 56% 30% 4096 16 62% 37% 8192 16 68% 40% rifft~ rifftw~: 64 32 56% 30% 128 32 66% 31% 256 32 73% 29% 512 32 82% 31 1024 32 90% 33% 2048 32 100% 40% 4096 16 57% 27% 8192 16 64% 29% i'm planing to add fftw~ and ifftw~ objects, soon... cheers...

Newbie question re: pd and OSX setup
by jj headski 23 Feb '04

23 Feb '04

This is a newbie question so please be patient with me. I have a Mac using OSX 10.3 and have a M-audio Ozone midi keyboard. I installed Adam Lindsay's "package" pd 0.36 installation and am having some problems. I searched the achive and noticed alot of people have similar problems, but I still don't know whats wrong with my setup. When i launch pd I get the following: could not open midi input device number 1: Invalid device ID. using default input device number: -1 using default output device number: -1 nchan 2, flags 3, bufs 8, framesperbuf 256 Error number -9997 occured opening portaudio stream Error message: Invalid device ID. When I open the "test audio and midi" patch from the help menu it seems like no audio or midi messages are coming in or out. when I select the "test tone" from this patch sometimes there is a white noise type sound, but most of the time nothing at all. so I typed in: pd -midiindev 1 -midioutdev 2 still nothing. I also typed in: -soundindev -soundoutdev nothing. What can I do to get it to work. How will I know when it's all connected correctly. I would greatly appreciate any help anyone could offer. thanks _________________________________________________________________ Take off on a romantic weekend or a family adventure to these great U.S. locations. http://special.msn.com/local/hotdestinations.armx

Apologies, I got the address wrong last time, so let's try this again! The p-t-player~ is now online. This is a sample player that gives the user independant control over pitch and time. You will need the zexy external to run this! It can be found at http://www.pure-data.org/Members/loneshark/pitch-time-sample-player/file_vie w Enjoy! Lone Shark Lone Shark: Aviation.

Reminder: Call for (Your Linux) Music still open until Feb. 29th
by Frank Barknecht 11 Feb '04

11 Feb '04

Hi, this is a short reminder, that the team organizing the 2nd LAD Conference is still accepting and looking for music created using Linux: From April 29th to May 2nd, 2004, the Institute for Music and Acoustics of ZKM Karlsruhe, Germany, will host the 2nd conference of the Linux Audio Developers (LAD). As a new feature there will be presentations of music in addition to technical talks. For this, we are looking for music that has been produced completely or mostly under Linux. We are looking for: * Interesting demos of sound synthesis, sound processing, etc. * "Classical" computer music compositions, to be played in a concert setting Pieces from areas such as Electronica, * Chill-Out, Ambient etc. Deadline for submissions is February 29th, 2004. The jury will award 3 grants to participants to contribute to their travel expenses. More details here: http://on1.zkm.de/zkm/stories/storyReader$3685 http://www.zkm.de/lad/ If you have further questions, Matthias Nagorni <mana ET suse.de> or Goetz Dipper <goetz ET zkm.de> will surely be able to answer them. See ya in Karlsruhe. ciao -- Frank Barknecht _ ______footils.org__

usb iobox comming - testers needed !
by Christian Klippel 10 Feb '04

10 Feb '04

hello all, first, sorry for cross-posting ..... second, sorry for the long posting ;-) after a (way too) long time, i finally got the basic usb implementation of my multi-iobox working. that box will be the follow-up of the 88-port ad-module for the pc-perport i have done a long time ago. wit the new usb version everybody should be able to use it, on any computer providing usb and a usb-hid (Human Interface Device) driver. that means, linux, os-x, windows ..... the box is not completely finished yet, but will be in about 1-2 months. in fact, the usb implementation on the microcontoller took the most time ... just put a look at the usb specs chapter9, plus the hid definition plus the hut (Hid Usage Tables) stuff ..... and you will get a impression .... what's needed now are testers, that will try out the current usb-firmware of the microcontroller connected to different machines. to help me out with that you will currently need : 0.) a cimputer with usb and hid drivers (that means: if your comp can use a mouse/keyboard/joystick... on usb) 1.) a programmer that is cappable of burning the microchip pic 16c765 microcontroller 2.) of course one if that microcontrollers, hard to get in germany, sorry. be sure to get the -jw version, which is uv-erasable. otp-chips are a waste at the current state of my development.... remember, its just a test firmware.... 3.) the current test-firmware from http://mamalala.de/iobox-test.zip 4.) a small prototype board, a usb-b connector, a cable from usb-b to usb-a (to you computer) and led's (with 1k resistors), buttons and faders as needed. take look at the microcontrollers datasheet (http://www.microchip.com/1010/pline/picmicro/category/perictrl/14kbytes/dev…) we need a 6 mhz xtal, portb is used to display led's, portd is used for 8 buttons, an0-an7 as analogue inputs plus the two pwm outputs on rc1 and rc2... 5.) pd or jmax with a event-device object (on jmax i made ev_dev, i think h.c. steiner has made a similar object for pd on linux) after burning and assembling, the thing does the following : on connecting to the computer, it enumarates to the host as hid device. it sets up 64 led outputs, 64 single key inputs, 88 adc inputs, 64 dac outputs and a 3-byte in-/output. the adc out's are declared (by the device) as absolute events, the buttons and led's as what they are, respectively. the dac is accessed as led, just with a 16 bit value range instead of the usual 1-bit on/off state .... the 3-byte in/out is done as one 3-byte wide button and a 3-byte wide led. currently used by the chip (as this are the built-in capabilities) are 8 adc, 2 dac (done by using the pwm outputs of the chip) , 8 buttons and 8 led's. (see http://mamalala.de/iobox-test.jph how that looks in jmax) that makes up the following events : inputs: (from device to computer) a: type 1 (key) code 256 - 263 (would be 256 - 319 in full version) range 0/1 (on/off) b: type 3 (abs. movement) code 6-13 (would be 6-92 in full version) range 0-255 (would be 0-255|1023|4095 in full version, depending on used adc) outputs (all are type 17:led) a: 0-7 (would be 0-63 in full version) range 0/1 (on/off) b: 64-65 (would be 64-127 in full version) range 0-256 (would be 0-255|1023|4095 in full version, depending on used dac) the rawbyte in/out's do nothing yet, but will be used for thing like buffered midi in/out, serial in/out, rotary encoders, small lcd displays, [put your ideas here].... now comes the point where i need your assistance : please test if the device connects to your computer without error. if you are on linux, test it's in/output. to send to the device in a propper way, you need a recent linux-usb driver. older ones (for example 2.4.18) dont include the report-id to the device, but we need that ;-) newer drivers do (as in linux 2.4.24 and up....) all the i/o should be do-able by the standard linux event input device interface (evdev) and the linux usb-hid driver compiled to use that interface.... more important to me is, if you are on mac/windows/.... : i cant supply objects for pd/jmax/... on these platforms. but, from what i expect they should be easy to write. just access the hid interface of the host, it will give/take the reports as needed..... for example, a usb-hid conform "driver" in source-form for a mouse, keyboard, joystick, tablet.... should provide a good basis for that..... if you plug it into window, it already announces itself as unknown hid device. please help, provide some objects for that thing ! all the linux stuff i will do myself, ev_dev is already there. what i will do next is a alsa-driver that wraps the device into a midi stream, for use wit other sequencer/synth apps. such a thing would be nice on other platforms too. imagine all midi-conform apps could use that thins faderbox, for example... ok, thats all for now. if you want to try that and help me out on that part, drop me a note and "just do it". report back your experience.... thnaks a lot, chris
