Re: [PD] joystick button-mashing
by jsarlo＠UCSD.Edu 28 Aug '05

Which OS are you using? Can you send me an example of your patch? The joystick object sends both the button id and state for each button press event to avoid any ambiguity (or at least it is supposed to!). So I'm not sure why your patch is getting confused, but it might be that you (like any good Pd user) are assuming that the rightmost outlet fires before the second-to-the-rightmost outlet. The joystick object actually sends the button-id first and then the button-state. So what you want to do is use a "trigger" object and an "int" object to reverse the event ordering. Something like: [ joystick ] | \ | \ | [ t b f ] | / / | / / |/ / /| / / | | [ int ] | | / | / | / [ pack ] | [ route 1 2 3 4 ] Here, the first four outlets of the "route" object should be the states of the first four buttons.

[OT] New Media programming language net-resources?
by vade 28 Aug '05

28 Aug '05

Hello list, looking for the hive-mind answer to a random question: is anyone aware of any active, thriving message-boards/irc channels/etc that concentrate on new media programming environments/theory/practice: ie Max/MSP, PD, Gem, Processing, CSound, hardware hacking, sensors.. midi, etc etc. (and I dont necessarily mean just one, but an all inclusive one, ? Id love to find a happening IRC Channel or something similar to pose some questions to some folks regarding processing and technique (but the forum is waaaayyy to empty). Just curious if anyone knows. Thanks a lot // (btw forgive the cross posting if you are on other mailing lists :) v a d e // http://homepage.mac.com/doktorp/ doktorp(a)mac.com

Change a signal's pitch :: octaver
by Alexandre Quessy 28 Aug '05

28 Aug '05

Hi, Its been a few months since I wonder what would be the algorithm to write an signal's "pitch changer" in Pd. I searched the archives, but I cant find any message about an octaver or a pitch changer. This can be done easily with requencies, but what about signals ? Would it be possible simply using expr~ ? Maybe I need to review my maths... Thanks!! aalex

A mute device
by Chuckk Hubbard 28 Aug '05

28 Aug '05

Hi. I came up with this as a way to mute a stream of numbers. Basically, I want my notes' names to update automatically as I drag them, but if I change the name manually and hit the little update button, it was renaming them as soon as they were repositioned, since I have a metro going. I have it set up to add the x and y movements of the array to those of the top-level struct, and zero those of the array. Tried stopping the metros, but it quickly got too complicated. I fixed it so it wouldn't change when I updated the position of a manually renamed note, but I found it did the same thing when I switched notes or loaded a new file, because I was using the "change" object. Here's what I did. The "set set $1" message is useful, I'm glad it works. This way the value of the change object is set to the incoming value before the receive is turned back on. Now, though it gives these error message of raty not existing, so I just created two unattached receives, one "raty" and one "nothing", for when one is sent before switching back; but suddenly my application would crash any time I started that loop. I deleted the extraneous receives and it's fine, with the messages again. Is it illegal to send a "receive whatever" message to a non-GUI receive? -Chuckk

string concat in PD
by thewade 28 Aug '05

28 Aug '05

Hello list! I am fine, thanks for asking! How are you? I am trying to open two files using one symbol. For example: [0] [symbol poop] [t a a] [append .dur][append .vel] [; > [array read $1> ...to read both poop.dur and poop.vel. (but not get "poop .vel" with the space) Is there a way to do this? Thanks! -thewade

asio and multichannel
by Thomas Ouellet Fredericks 28 Aug '05

28 Aug '05

I just bought a "sound blaster audigy 2 ZS notebook" and could not get it to work with ASIO until I found out the card will only work when you set pd's sampling rate to 48000 with the "creative asio" driver or 96000 with the "SB Audigy 2 ASIO 24/96" driver. Just wanted to let the list know of these details in case anyone wanted to buy one. I hope this does not affect any of my patches! Tom

sequencer help
by shift8 28 Aug '05

28 Aug '05

hi list - i'm working on a non-looping sequencer using pool, and wanted to hit you guys up for some questions/ideas. the patch is attached, and it super simple at this stage so it should be easy to understand. the main point of the patch is to play and record at the same time (optionaly to not record while playing back, but i know how to do that). i need to figure out a way to block further updates from pool to control objects if the user make a manual ajustment to a control during playback/recording. any ideas? thanks in advance. -s

Re: [PD] joystick button-mashing
by poil 27 Aug '05

Thanks I don't think I tried gripd before for joystick - both are by jsarlo! It's great but it only supports two joysticks/joypads. I am using two dual PS2 to USB adaptors with four PS2 controllers plugged in. Running two instances of gripd doesn't seem to work as they both share the same send/recieve names. > hello poil, > > try using using gripd- you have a different receive for each button/axis > > pete > > > poil wrote: > >> Hi >> >> I am using jsarlo's joystick extension on windows which sends >> button-id number and a binary button-state for the whole pad on its >> last two outlets respectively.
