I made a nifty little patch for reading HID information from an Xbox controller and spitting it out all organized, and it was working fine about a month ago.

I finally decided to put it to use and now the HID object causes PD to crash without fail! O no!

When I open the hid help file (which I built my patch from), I click the green box that turns on the hid reading, and as soon as I click the object that lets me choose which hid (channel?) I'm reading, the whole program goes belly-up.

Why is this happening now and not before? Hid worked fine before... Is it my system?

I'm using pdL20rk and ubuntu 16.04

as always, I appreciate the help.

updates: vanilla crashed as well and jstest shows the controller is working fine

also ubuntu generated an error report but I've no idea what it means or what info would be useful to include from it. The most relevant piece seems to be "pd crashed with SIGSEV in hid_poll()"

for every position on the hradio in the help file patch, when I click it the console reads

error: [hid] open /dev/input/event0 failed
error: [hid] can not open device x

where x is the position of the hradio and the variable attached to the open message

FIXED?
for some reason hid was recognizing the controller as device 19, so I made an open message for device 19 and it is polling the controller.

This still doesn't tell me why it was crashing, which is worrisome.

@lovelovevideo Damn...... I thought someone else would reply. It has to do with old technologies and ways of reproducing them on computers.
In ancient times this effect was achieved by speeding up and slowing down the tape (a very long plastic film coated with........ enough..... see here https://en.wikipedia.org/wiki/Magnetic_tape)
Obviously that would also change the pitch. But if the tape head (reading the information) was a complete circle (for domestic stuff like "cassettes" it was a small arc of a circle) then the head could be revolving slowly in one sense or the other, and so read the information at a different speed....... and so compensate for the change in speed of the tape.
Of course in the digital sampling domain the solution has to be different.... but only slightly.
In the analogue example the number of samples (ferrite bits stuck to the tape) being read every second by the revolving head was irrelevant. Not so in the digital domain...... the sample rate being necessarily constant.
To get around this constraint extra copies of samples need to be added when the speed is slow, and some need to be removed when the "tape is running fast" so as to keep the sample rate stable.
Hence the "chunk size" (a revolution of the head) and the continuous re-adjustment of the phase so as to insert (copies) and drop samples as necessary by continuously updating the read point of tabplay......
Of course, when in doubt ask @katjav .........http://www.katjaas.nl/pitchshift/pitchshift.html

I just installed Ubuntustudio 15.10 Wily Werewolf 32bit on a thinkpad and I am trying to upgrade PD to extend. I am fairly new to linux but it seems like the instructions on https://puredata.info/docs/faq/debian fails.

This is the log from executing the commands. Any suggestions and help will be appreciated

@mholes1 You might be able to do it using [key] and [keyup]....... needs looking into unless someone has done it already....... woof! Gilberto will know (or EEight)! If you turn the note on with [key] and off with [keyup] that might do it!
hid.zip (you need to right click for help the [hid] object about half way down on the left hand side).......
Here it is (I can no longer remember what was in the original Pd that I downloaded)......

David.

I have usb device (non HID) that sends X, Y, Z (and more) signals via OSC messages that I'm reading in PD. I very much need to send it into [hid] library for re-routing to various axis, but cannot find a way to build a patch to take OSC > PD patch(?) > [hid]. Basically that takes [int] OSC messages, converts to a simulated HID device, then feeds into the [hid] library, then reroute using [hid] as normal.

Do you have any ideas or a patch that might work?! Any help would be much much appreciated... Thanks.

that's kind of the extent of the messages and I don't really know what to make of it. What's with all that HD jazz? I certainly don't want that.

but yeah, so far, I can only get 1200 1600 and higher. Maybe if I worked in YUV?

edit: I forgot to mention that I'm running a macbook pro with snow leopard.

Hi,

I've got a quick question to Maelstroms patch.

When I hit [stop( once while playing, then [play(, the counter are out of sync, meaning, they don't hit 0 at the same time anymore.

When I hit [stop( twice before hitting [play( again, the counter are in sync.

So, for now I fixed it for my needs with a [delay], sending the needed second hit.
But I would really like to understand what is going on.

Is it something I'm doing wrong or what?

Anyway, thanks for the awesome inspiration with the clock solution.

Regards,
j

hey Arif, thanks for the reply. I have input what I think is right. Still no joy. Now it is disagreeing with CoordsCalc. I have included the code. I already had some of the things from the example. I think I just need to add integers but I dont know how or what to put.

I am trying to use MIDI to trigger specific drum hits, attached best guess. I am trying use specific keys for different drum hits loaded into arrays. The values that seem to be comming out of my [== 36], to try and trigger specific hits, seem to be right but I am still get a drum hit no matter which key I press.

Any ideas thanks
