Re: [PD] @Porres Questions about PVoc

[S.E.P.]

Thanks for your reply. Of course, I understand you're busy. In the
meantime, I could just set something inside your patch that bangs the
"bounce" button at the right moments, but that seems rather silly and
inefficient! I'll have another look at its innards soon.

 Dear Mr. Porres,

 Thank you for the creation of your time-stretching patches. I have some
 questions about their utilization and hope that you can give me some
 advice. Attached are two very different samples that I want to be able to
 stretch out indefinitely.

 In the case of the contrabass file, I find that manually clicking on
 "bounce" creates a much more seamless effect than automatic bouncing (which
 has a very audible cross-fade). How would you suggest manipulating the
 patch to automate a smoother bouncing effect? I don't think this is a
 question of how the files are cut, but I could be wrong...

 Otherwise, I find running both files at 150 Motion and 4096 window size
 with Lock off works quite well. As with some other Time Stretching patches,
 the contrabass' upper spectrum becomes strangely isolated and present
 (compare it to a normal playback of the same file). Any ideas about that?

 Best regards,
 S. Elliot Perez

To avoid duplicate errors, etc do basically the same thing without adding the 
library path itself:

* add the single  ~/Library/Pd directory path
* create the object with the lib name aka maxlib/average

Is there a way in vanilla to add a dir that pd can search within like extra? In 
this case, we’d want -lib maxlib to work within the given ~/Library/Pd. I know 
there was some development around this but I don’t remember if it was on this 
specific issue or not.

Re: [PD] Spring Reverb?

[jlistshit]

Hi, i had looked into this before (not in PD). When you search for the 
modelling of a metal helix you'll get into intense math pretty quickly

(see 
https://www.era.lib.ed.ac.uk/bitstream/handle/1842/3718/BilbaoS_A%20Virtual%20model.pdf?sequence=1
 )

so i decided to copy params from typical spring reverbs into delay chains.
A simple version looks like this
two delay chains, 25 and 40 ms (typical accutronic spring tank from guitar 
amps), 
each with feedback through an allpass filter, which should allow to smear the 
HF usually in a range of max 1ms.
add faders for 
- the delay time (ratio 2.5:4 - i prefer to have a range of 2.5 to 125 for the 
25ms delay chain, the second delay chain x 1.6), 
- the amount of feedback
- the amount of smear on the feedback.
- a control for randomization (see LFO thing below)

Unfortunately i am not aware of an allpass filter object for PD, as i use only 
vanilla, but i am sure you'll find one.

Additionally, to create more interesting pictures, you can
- add an LFO per delay chain with a line object set to 500 (to create a sort of 
glide) to modulate the delay time slightly or heavily.

Like i said, i didn't do this in PD yet, only in maxmsp and on patchblocks, 
but the idea works fine (gritty!) without heaving to go into heavy math.

My patchblocks patch is here:  
http://patchblocks.com/groups/patch/shattuh-02-spring-reverb-emulation

And someone made a video of how it sounds here (patchblock on right side runs 
the shattuh patch:
https://www.youtube.com/watch?v=4_e3hrkLRAc

Best of luck :)

Re: [PD] Can someone clarify how to use libraries with Pd-vanilla on OSX

[Benoît Fortier via Pd-list]

It works for me as well, the only thing I noticed on my system is that by doing 
it that way (Aykut's way), the help browser gets messy : externals help files 
gets duplicated, they appear both in the help browser's "root" folder and in 
their respective external's subfolder. That made me wonder if it really was the 
good way to do it.
Also I remember that at one point it was mentioned that the best practice was 
to declare external folders in the patch and we somehow where encouraged to do 
that. Is that the recommended way of doing things with pd-vanilla right now?
Thanks everybody! Benoît Fortier

 Hey Martin, 

that's what I did and it worked
- in my system, deken has downloaded selected lib (say maxlib) into ~/Library/Pd
- and then go to Preferences>Path and add the directory of the lib you've 
downloaded
- click apply
- and create the object say |maxlib/average|

Re: [PD] @Porres Questions about PVoc

[Alexandre Torres Porres]

replying or writting only to me is fine I guess :)

but honestly, I wont be able to touch this soon as I'm already doing a lot
more work on pd stuff - I've always used it with a fade, so I don't know.
But it's marked as a bug report, thanks.
