Dear all, it's with great pleasure that I share with you this piece.

Output numbers consecutively, one at a time in PD
by Sebastian Valenzuela 12 Sep '11

12 Sep '11

Hello, I need an object that will output a sequence of numbers [that I would program], one at a time, every time i send it a bang. I need this to loop. So if my set of numbers are [2, 5, 7] it would go... "bang" - 2, "bang" - 5, "bang" - 7, "bang" - 2... etc. Is there such an object? If not, what could I use to make this operation? Thank you for your help, Sebastian p.s. Sorry if this is a simple operation, i'm sort of new to the pd environment.

Can GEM select a color from an image?
by Sebastian Valenzuela 12 Sep '11

12 Sep '11

I am in the process of writing an algorithmic piece where I take pictures, determine the most prevalent color in that picture, then store that as a number in an array. I would then call on these numbers to determine the triggering of samples. Is there an object in Pure Data that can determine the most common color in an image? If so, how does it work? Thanks for taking the time to read this, -Sebastian

Book Hunt (Ross Kirk)
by Andy Farnell 12 Sep '11

12 Sep '11

Anyone near London UK got a copy of Ross Kirk "New Digital Musical Instruments: Control And Interaction Beyond the Keyboard", 2006? Begin forwarded message: Date: Mon, 12 Sep 2011 20:04:34 +0100 From: Andy Farnell <padawan12(a)obiwannabe.co.uk> To: Duncan Brown <brown.df(a)gmail.com> Subject: Re: Major Project - Book Hunt There is such a thing as an inter-library loan request. You fill out a form at the BL, they ask York if they can loan it and they post it down to London for a couple of weeks. It usually costs a fair bit, maybe 20 or more. But better than asbestosis. I might forward this to some folk in case anyone knows of a copy near London. best Andy On Mon, 12 Sep 2011 19:52:28 +0100 Duncan Brown <brown.df(a)gmail.com> wrote: > Hi Andy, > Hope your doing well? > I'm trying to get a look at this book as part of my project (Novel Interfaces for Musical Performance) but the British Library are unable to release it.

Multiplying signal by complex number to create and see phase shift
by Rick T 12 Sep '11

12 Sep '11

Greetings All I plan on adding a phase shift to a signal/a wave file I import which is easy enough mathematically example: if the signal is x=sin(2*pi*1*t) to do a phase shift I would just multiply x*e(-i*pi) which would phase shift the signal by 90 degrees. But how does one multiple signals by complex numbers in PD like -i? note: there will be a several different phase shifts so a simple hibert transform won't work in this instance thanks --

updating table is slow
by Rick T 12 Sep '11

12 Sep '11

Greetings All I'm trying to update a table every second so I can see phase and frequency changes but it takes about 5 seconds to see the changes. How can I speed this up but still see a 1 second sample of the table? Also is there a way to show two signals on one graphical table? Like in the hilbert~ example (I tried doing a tabwrite~ out-right and a tabwrite~ out-left but this didn't work thanks

audio > 1.0 not clipping?
by Rich E 12 Sep '11

12 Sep '11

Does anyone know why this doesn't clip?: [osc~ 200] | [*~ 1.5] | [dac~] I'm trying this using pd 0.43 and the audio still sounds good (although some extra harmonics can be heard), despite the phases being in the range of [-1.5, 1.5]... ? Cheers, Rich

Is it possible to transmit serial data from the computer through the serial port of Arduino to a serial lcd display while running firmata? And if yes, how? Ingo

filtering out non-unique, unordered lists from collection of lists
by tim vets 11 Sep '11

11 Sep '11

What's a good way to compare a list to a collection of other lists to see whether it's already present in the collection? >From a collection of lists, I want to keep only one instance of each unique list. Also, I would have to treat the lists as 'unordered' so that "1 2 2 3 4" is considered as being the same as "2 4 3 2 1", and only one of them will be kept. thanks, Tim
