Smooth looping
by Frank Barknecht 25 Apr '10

25 Apr '10

Hi, not related to the thread on smoother audio in Pd, I am struggling with doing a smooth loop player for data stored in tables. One building block for this is attached: It is a simple tabread4~ lookup that should loop over a configurable section of a table and play it back with various frequencies. As you'll easily see, I use a [phasor~] | [*~ loopsize] | [+~ loopstart] | [tabread4~ table] idiom here. Now I would like to avoid enveloping the rewind sections, so I built an elaborate mechanism to set the loop points as good as possible by hand. Test sections let you load a sample or try to find the smooth loop points inside of a sine-wave table graphically. Now my problem is, that even when I have found a nice and smooth sounding loop section, as soon as I start to change the frequency played (with the "pd transpose" things), the sound gets very distorted. I'm puzzled: Shouldn't the tabread4~ interpolate correctly in this case? Any help or explanation is appreciated. (Except anything involving crossfades: I know I could do that and I guess I also know how.) Ciao -- Frank Barknecht Do You RjDj.me? _ ______footils.org__

PD autoselects from a folder
by Andrew Faraday 25 Apr '10

25 Apr '10

Hey All It's the perpetual newbie here again. I've been working on a generative gem patch (to run on a seperate machine when I work) and I want this to load and re-load images from a selected folder. So far the only thing remotely like it I've found is [openpanel] which requires a user to choose. I really want an object to load files from this directory randomly or sequentially without human interaction. I think I've seen something like this before, just no idea what it is. Also, I could use something like it for audio Thanks Andrew _________________________________________________________________ http://clk.atdmt.com/UKM/go/197222280/direct/01/ Do you have a story that started on Hotmail?

[ctlout] and Korg's nanoKONTROL
by Erik Mazza 24 Apr '10

24 Apr '10

Hello, Has anyone had any success writing MIDI data to the nanoKONTROL? I can read MIDI data just fine. The problem is I set the scene button to change the MIDI channel in hopes of expanding the controller's functionality, but when the scene is switched then switched back, all previous momentary buttons are off. I was thinking of storing the control data then writing it back when the scene switched, but apparently it doesn't receive midi data. So I'm kinda stuck. Any ideas? -- Eric Mazza <mazzarotti(a)gmail.com>

well, we are in 3 then. I'm using it a lot trying to (slowly) rewrite the framework of C::ntr::l. IOhannes, may I keep on using it to develop the next version of a software has been released publicly? or am I playing with fire.. :) I find IEMGUTS so useful. I'll look into them better. since I use as many abstractions and > $0-variables as I can, the possibilily of getting easy acess to parent > parameters is quite useful. so there would be at least 2 users of iemguts. > > -- Marco Donnarumma aka TheSAD Independent New Media Arts Professional, Performer, Teacher - Edinburgh, UK PORTFOLIO: http://marcodonnarumma.com LAB: http://www.thesaddj.com | http://cntrl.sourceforge.net | http://www.flxer.net EVENT: http://www.liveperformersmeeting.net

I thought everyone knew the meaning of "red". Didn't Hollywood make a movie about "reds"? Sorry for the bad joke. C'est dommage!

In the latter case aren't you just expanding the output of the phasor to a different point in the file that is no longer necessarily loopable? Matt
