Re: [PD] Indexed array selection
Hi Fred, The list-abs library has an object [list-idx] which might be useful. It's pretty easy to use. Kind regards, Lorenzo. Fred Smith wrote: Hello Folks - I know there must be an easy way to do this, but I'm having terrible trouble figuring it out. Is there an easy way to use a integer input to send a message out of an array of messages? Ideally, it would look like this: [bang] | [2] | [newcommand apple beats carrots cheeseburger] | [print] and the output would be carrots (given 0 based indexing). Does this command already exist? (Oh, and I'm pushing this into a GEM text object, so the screen would say carrots in some way). I apologize if this is obvious, my head might be fatigued. select and route take a value but split it into a bunch of different directions. I want to go the other way Thanks for the time if anyone has a suggestion!!! ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] pack object resolution issue
I think I get it: the last controller value to be stored in pack (thru the rightmost inlet) was not beeing triggered by anything hitting the leftmost inlet... as a result, I could never get the extreme values. Typical Pd programming mistake! I corrected this and now, it works fine. Thanks for your help. D.S From: David Schaffer Sent: Saturday, October 10, 2009 4:56 PM To: pd list Subject: [PD] pack object resolution issue Hello there, something strange happens to me when routing ctlin signals thru a pack object and then unpacking the result afterwards: my midi values seem less precise. I noticed it when using extreme values (either 0 or 127): it gets me somewhere between 0 and 18 or between 118 and 127. As a consequence, similar midi fader positions give me slightly different values, which is annoying (ctlin's direct output works fine and always gives me the same results). Has someone else been thru this before? Thank you!

[PD] making a perceptual spectrum analyzer
how to make a perceptual spectrum analyzer? the magnitude output of rfft~ seems to need some tweaking, like: 1) correcting amplitude of bins 2) spacing the bins from equally linearly spaced to equally logarithmic spaced (for outputting a set of frequencies like: 62 125 250 500 1000 2000 4000 8000 16000) does anyone already did it? in part 2), apart I don't know how to do it, I'm not sure if I need to sum up all the bins belonging to a frequency band, or to average them ...? ~ signature.asc Description: OpenPGP digital signature ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

have a look if you can find some constant Q filter analyser or bar filters, it can be a good starting point. hope that helps loic On 11 oct. 09, at 21:26, mescali...@gmail.com wrote: how to make a perceptual spectrum analyzer? the magnitude output of rfft~ seems to need some tweaking, like: 1) correcting amplitude of bins 2) spacing the bins from equally linearly spaced to equally logarithmic spaced (for outputting a set of frequencies like: 62 125 250 500 1000 2000 4000 8000 16000) does anyone already did it? in part 2), apart I don't know how to do it, I'm not sure if I need to sum up all the bins belonging to a frequency band, or to average them ...? ~ ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
