Dear all,

this is my first post and I hope its not too much to ask.

Im new to .pd but have been through many tutorials and discovered/playing around with the many patches that are out there.

Im basically trying to work out a way to create an application that allows a live input (voice) to draw a coloured image according to the amplitude (as the vertical control) and pitch (as the horizontal control).

Just like mapping a score as in this article:
http://crca.ucsd.edu/~msp/Publications/icmc02.pdf

there is a javascript greyscale similar to the idea I speak of here

I have also been investigating the use of these .pd's trying to find a way to gain this effect;

C::NTR::L by Marco Donnarumma
(particularily editing colour with pitch, i think his colour modules great)

and

the voicedrawer.pd http://adrjork.altervista.org/puredatatutorials/VoiceDrawer_081021.pd.zip
by adrjork
essentially registering a wave form to an inputed sound.

Please can someone point me in the right direction, i cant imagine someone hasnt done it before but id be really intrigued and very grateful to know how.

Comments and help greatly appreciated

Anyone?

I have attached my attempt, ive tried implementing many patches to make this work with no success.

I just want to draw coloured lines or shapes according to volume and pitch. Any ideas would be fantastic.

Cheers.

Can I please get some advice to point me in the right direction?

I am working with oboe to pitch and volume controls for video. Have you had any more success with your patch? I have found it easier to work off of midi numbers with graphics and also use scale to get the numbers in the right range. I wonder if you could start with an ellipse or rect in the gem window and then affect it with your pitch and volume parameters. Maybe start with an object that is affected by your audio input. This would be the easiest I think. I will check back. I have done this in processing but not pd or I would post. It looks like GEM is not getting the correct parameters and that appears to be what needs to happen first. Best, Robbie
