Multicolor spiral controlled by MIDI

Mihau's picture

Hi everyone!

I'm totally new with Quartz Composer and I would like to ask you for help with my project.

I'm trying to make visualization for interactive concert, which includes electric violin and keyboard. I'm working on making multicolor spiral controlled by my keyboard. I made a spiral multiplying sprites using iterator, gave each of sprites specific color (using HSL color) but I have no idea how to control each of this sprites with my keyboard. :) Keyboard has 88 keys, so the number of iterations is also 88. I want to change one sprite (color, width, height, XYZ position) with one key from my keyboard. Is it possible using structure maker and structure index member?

I would be grateful for any response.

Thanks, Michal
