by Enrique Erne 07 Aug '06

07 Aug '06

hi all when i change the number of a vradio in an abstraction i get something like invalid command name ".x499200.c" it just happens when the window of the abstraction is not visualized. if it is open there is invalid command name . it's not a big problem but a bit annoying after a while. mainpatch: [; myVradio number 2( abstraction: [r myVradio] | [vradio]

Vslider (runtime) range change.

Hi list, Is there a way to change the range of a vslider, or, in general, of a gui object, RUNTIME? Thank you, Tasos --------------------------------- ΓΓ±Γ§Γ³Γ©Γ¬Γ―Γ°Γ―Γ©Γ₯ΓΓ΄Γ₯ Yahoo!

Vradio issues.
by Tas Pas 07 Aug '06

07 Aug '06

Hi list, I've made a patch that loads a sample and, when you press the "b" key, it launches it. Till here all ok. When I tried to customise the message that arrives in [tabplay~]'s inlet, using 2 vradios (one for the sample start and the other for the playback duration), I faced a problem that seems to be quite odd. Whenever I set the value of the start of the sample and trigger a bang, I can see that the value is set. Whenever I set the value of the playback duration, I have to trigger twise in order to see the value changed. I attached you the patch (sampler_test.pd) and the abstractions I used to make it to take a look for yourselfs. Thank you Tasos --------------------------------- ΓΓ±Γ§Γ³Γ©Γ¬Γ―Γ°Γ―Γ©Γ₯ΓΓ΄Γ₯ Yahoo!

Re: [PD] tabread4~ help
by padawan12 07 Aug '06

Let's say you have an 8 second clip at 44100Hz. To acheive standard playback at the original sample rate you want to scan from zero to t * sr in t seconds, that's 0 to 352800 in 8000ms (line gens are specified in milliseconds) You could say [352800, 8000( | [line~] But you want to be able to vary the rate, so fixing it in a message isn't so good. A line generator is usually normalised, so whatever the rate/time we often make it scan from 0 to 1. You then multiply that by the total size, so [1, 8000( [44100( sr in samps/second | | [line~] [* 8] time in seconds | / [*~ ] | [tabread~] Substituting the time in the message time ------- / | [1, $1( rate | | | | [line~] [* ] time in seconds | / [*~ ] | [tabread~] Now you can vary your rate and time. > I want to use tabread4~ in conjunction with other objects > in one case to change the speed and keep the sample at the > same pitch You cannot do this with a simple tabread~, what you describe is timestretching and that's another story. > and in another case to just change the pitch and keep the sound > length the same. Sadly that's also not something you can do with simple playback/reading either, what you describe is pitchshifting, a whole new can of worms. > Is there a way to do this? Yes indeed, there are several ways, but try and master the standard playback methods first because the pitchshift and timestretch methods are quite complicated and you will need to fully understand sample playback before moving forwards.

Infernal symbols
by Chuckk Hubbard 06 Aug '06

06 Aug '06

I usually find ways to just avoid understanding message selectors in Pd, but I can't find a way around this. [hottentot( | [add $1( says "argument number out of range". How on earth can I add an arbitrary symbol to a line in a [textfile]? -Chuckk -- "Far and away the best prize that life has to offer is the chance to work hard at work worth doing." -Theodore Roosevelt

Junior Pd Logic Circuit Kit
by Chuckk Hubbard 06 Aug '06

06 Aug '06

I'm getting interested in this stuff. I haven't looked up any standard circuits, but I'm fairly certain my adder could be realized with fewer NANDs. I also didn't take any care for execution order, so there's some odd results before it all gets sorted. At first I was going to use [sig~] and [env~] at all the inputs and outputs, but I don't know that it would matter. Hmm, now I'm looking at the logical operators already present. Oh well... -Chuckk

help browser in pd 0.39.2
by klaas de Baas 05 Aug '06

05 Aug '06

Hello list, I recently uninstalled pd extended 0.38.4 from my windows xp computer, and installed pd 0.39.2 and gem, because I really wanted to work with the new gop functionality. However, when looking for help, pd now opens a windows "open file" dialog, instead of the help browser I was used to in pd-extended. I quite liked the old help browser. Is there any way I can get it back in pd 0.39.2? Thanks Klaas

Phase Cancellation
by beau c 05 Aug '06

05 Aug '06

Hi List, I am trying to extract a drum loop from a soundfile, which has a violin loop mixed in. Earlier in the song I got a clean pass of the violin with by itself. I was wondering how I could change the phase of the violin loop by 180 degrees so that when I mixed it in [+~] with the other sample the violin loops would cancel eachother out. Leaving only the drum loop. Does anyone know how to do this with pd? Or any other programs/plug-ins? B~ www.cypod.co.nr
