PDA PD + GPS
by derek holzer 22 Mar '04

22 Mar '04

Hi all, I have a few questions about PDA PD: 1) What is the minimum spec for running PD under Linux on a palmtop? 2) Has anybody seen a way to get information from a GPS device into PD? My idea is to have a PDA running Linux + PD which can take acoustic samples at regular space/time intervals and tag them with GPS coordinates. Even the most general suggestions are welcome, but if somebody else has already figured this out, I'd really like to talk to you soon. Best, Derek -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 118: "Make what's perfect more human"

Re: [PD] pd + midi = glitches [calling all Gurus!]
by derek holzer 22 Mar '04

22 Mar '04

Thanks for the reply..... I'll see what I can do. One of my controllers is a USB-MIDI keyboard, however I am having trouble getting USB MIDI working, but that's a question for another list. One question: could you reproduce my problem in your setup? I mean the glitches? Or is it unique to my setup [in which case I can blame the unrecommended Ricoh cardbus controller on my laptop, perhaps...] thx, d.

[OT] soundfile compression
by john saylor 22 Mar '04

22 Mar '04

hi this is not pd specific, but it may have relevance. let's say i have a .wav file, and i want to make it smaller. this is the list of options i am aware of: 1. i can reduce the channels to 1 [mono] 2. i can reduce the sample rate from 44100 Hz. 3. i can reduce the bits per sample in terms of minimizing fidelity loss, i would guess that the list would go like this [with the least loss leading]: 1. channels 2. rate 3. bits is this correct? and what tools would i use to perform these manipulations? sox for all? if there are other methods to acheive this end, please feel free to suggest them. thx! -- \js !`'+>:@=' />' ]^' $ ?^'

Is there some other type of buffer that can store a recording longer? Thanks AP

I have a new little project running that uses GPS data to control a simple PD patch. http://130.208.220.190/hlemmC Pall -- Pall Thayer artist/teacher http://www.this.is/pallit http://www.this.is/isjs http://www.this.is/harmony http://130.208.220.190/panse

Good PD programming practice
by Trevor Agus 21 Mar '04

21 Mar '04

Thank you very much for your advice on good PD programming practice. The finished "good programming PD practice" is at: www.earcatching.com/pdconv This is intended to apply to situations where PD patches are being shared between users. I don't intend to tell you how you should be doing your personal PD programming! Specifically it is for a project in which 4 of us will be working on the same potentially large-scale patch. It is a partly a summary of advice received, but mostly a dollup of my own reasoning and personal preferences. Feedback is welcomed. I will update it with necessary changes and note any equally valid alternatives. Cheers, Trevor

recording to arrays longer than 34,5??
by doniguan＠stny.rr.com 21 Mar '04

21 Mar '04

Im working with xrecord~ and xgroove~ and ive been trying tabwrite. I cant seem to record more than the length of the array. Is there a way to make it so that it records, then changes the size off the array to the size of the recording? Thanks- AP

multiple fluid~'s sharing large soundfonts
by Larry Troxler 21 Mar '04

21 Mar '04

I've made a modifcation to fluid~ that solves a problem I had been having. I thought I would mention this here in case there's interest in making this a part of the official fluid. The problem I had with fluid~ was this: I wanted to load a large piano soundfont, but be able to process different voices (piano tones) seperately. For example, I might want to apply a filter envelope to each piano tone seperately. Initially I thought of modifiying fluid~ to provide a seperate audio for each fluidsynth voice, but this doesn't seem possible without actually modifying the fluidsynth code. Then I thought of using multiple fluid~ objects, with incoming notes routed to different fluid~'s using some algorithm to split up the voices. However, because of the size of the soundfont I wanted to use, it wouldn't be practical to load a copy of the sounfont in to each of the fluid~'s. So, what I have done is modify fluid~ so that if you send a "[ load sounfont.sf2 share (", it uses the fluid API to load a single instance of the sounfont, and then add that one object to all the active fluid~'s. Naturally, this API could be refined, but the concept seems to work so far. So, if anyone is interested in this kind of application, I could post the modifactions to fluid/main.cpp. I would do this now, except that it's probable that nobody but me has an application for this feature, and also because I'd want to hear ideas about the PD client interface - certainly it would be nicer to have something better than a message that blindly adds a sounfont to all of the active fluid~'s - but maybe this is fine after all.
