usb iobox comming - testers needed !
by Christian Klippel 11 Feb '04

11 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

how to do a sampler without scratch
by FFT 11 Feb '04

11 Feb '04

Hy. I know itÅ½s a stupid question. I want to do an audio sampler, and i used the scratch tutorial example. I know how to put the sample playing in loop..easy. ...the problem is when the sample ends and start again, the audio "connection" between this gap have the scratching effect. How can i stop this scratch FX, and get a constant loop? thank you fft

Max/Msp Patches
by tobias 11 Feb '04

11 Feb '04

hello, does someone know, how to use Max/Msp patches in pd. With "open" i can choose to enable Max files, but it doesnt work. i get some messages "cant creat object ..." for the nonexisting objects but the patch doesnt open. (using OS X and Max 4.3 and pd 0.37). it would save me a lot of work. Thanks tobias

Newbie Question--writing MIDI with PD
by MilesOkazaki＠aol.com 11 Feb '04

11 Feb '04

PD listers, I've written a instrument that outputs a stream of MIDI data--is there a way to capture this data as a MIDI file --either within PD or routing it into another application that can transcribe it (such as Finale, Protools, etc)? I'm using windows XP--- thanks, -Miles Okazaki

Hi! we're RBF-soft. [producing] maybe you haven't hear about as because we're from BarberÃ , and we haven't had the pleasure, and the community its so big, that its logic that you don't know who we're. Then, we're a designers, artists, dj's, vj's, animators and developers programmers,... we have made an instalations with pd,in bcn and mallorca,and we have made music with pd too, and streaming with pd, workshops of pd and reason (in Sabadell), aplication online with pd, ... (its now developing) do you need more information about as and more people that you dont know. riereta is not only the pd community, because we're doing more for pd, and other people that we know and not know. If you have more visibility than these person this not mean that you 're the one, and only the pd community existing in bcn, you know?Â¿. PD is for community not for few people living in raval (bcn), there're more people, well?Â¿. This -http://130.208.220.190/: website is not developed by Yves Degoyon with Pure-Data, :: Pall Thayer :: is the author of this project, you can't say this, this is false. And Riereta is not the only one in bcn, that made things with pd, do you understand?Â¿ maybe if we would have more vissibility (like riereta), you (Yves) will can know who 're RBF-soft. Pd: see u and saludations for the authentik people of pd community around the world!!!! around the things real!!!! RBF-soft.

11 Feb '04

Hi everybody, I was pretty active with PD for a while, but got kinda side-tracked unfortunatly. Anyways, if somebody could be so kind to help me back in the saddle. I need to round down a float. Right now the value (which is timer actually) is something like 24.4648736 I need it to be 24.5 in this case. I couldnt find an object to do this. But im sure ive missed something, as i know ive done this before. thanks for the help Anton

weird fopen behavior
by Jeffrey Hildebrand 11 Feb '04

11 Feb '04

in my external for some reason pd can't open a file, here's the code can anybody see anything that might be going on? basically pd keeps printing Error: can't open hrir.bin. there's nothing wrong with the hrir file and it's definitely not read-only. i'm totally confused now, scott //loads HRTFs into Pd's internal data structure, but it could be stored anywhere really if(x->firstfloat == 0) { t_int az, el, i; FILE *fid; fid = fopen("hrir.bin", "rb"); if(fid==NULL) { printf("Error: can't open hrir.bin.\n"); return 1; }
