I’ve been working on a light organ and related applications using the FFT on audio input, and would like to display the strength of chromatic (musical) notes using a 12-by-something array for say, six or seven octaves. But the ones available seem to mostly be 8-by-something, or 16-by-something.
Does anyone make such a thing with update times comparable or better than say, NeoPixel?
Thanks and Regards,
