My light to midi


I have just finished a preliminary version of the manual for the L2M interfaces I started selling on eBay last week. I will also be offering them on the internet via PayPal.

Download the manual here (PDF, 168KB) and you can view one on eBay here.

Hi there!

Do you think it is possible to have access to the document or have the schematic? The link doesn't work anymore. I'm trying to trig MIDI with light but finaly can't find how...

Thanks!

Hi there,
This stuff is really out of date.

What exactly are you trying to do? I am sure I can help you out.

Oh, thank you for your reply!

Basically, I'd like to use light for making sound. I'd like to do hand-drawn on films and convert them into sound with photoresistors.

Like Norman McLaren did in 1950

At 2:50 start the hand-draw sound.

So, I was doing a research and I found you "light to midi" and tough it can be a good way to do it. I have Arduino, Max/Msp but I have an hard time to understand those thing yet.

Thanks again!

Cheers,
Micheline

I don't have access to actually listening to the video where I am at the moment, but I guess my first question would be: how many photoresistors would you want to use? And also I assume you've considered other possibilities like doing a pixel -> audio conversion in the digital realm or any other type of real time video conversion?

To be honnest, I'd like to use 12 or more photoresistors. But I'd be very happy to do a smaller prototype with 4, 6 or 8 only.

Not sure I want to use real time video conversion, I don't have any camera anyway but wouldn't mind at the end transforming the sound with some realtime pixel/textures conversion in Max or something. Not just black and white but different intensity of grey may change the texture of the sound.

Hope it's clear, I speak french... It's hard to write that kind of thing in english.

Thanks again!

I can understand you perfectly :)

Okay, well I will make a simple example for you soon, using lets say 6 photoresistors. Then I will make a more complex example.

misoft said...

Is that true?!!
I don't know what to say, I'm totally exited!!!

Sebastian Tomczak said...

I am away from home for a few days until Wednesday, but after that I will make an example :)

Great, thanks again Mr. Little-Scale!

Just a simple question, according to the video link I gave you (when you will be able to watch it) do you think it is better to use photoresistor or phototransistor?

just a thought...
Can't wait to see you example!!!
