1  Using Arduino / Interfacing w/ Software on the Computer / MaKey MaKey Sampler in Max Issue on: March 26, 2013, 11:26:08 am
Hi I'm completely new to Arduino, and I'm not sure if this is the right forum but I've encountered a problem. When I hold down two keys for example 'space' and 'click' on the MaKey MaKey, and let go of one. It cancels the hold on both of them (sends keyup to max.

So basically if I press 'space' down to start playing an audio file in max and let go to pause that file, it's fine. If I hold down two keys on the MaKey and let go of one, both files will pause when I only want the file associated to the key to pause rather than all of them.

This seems to work fine with a normal keyboard so I'm assuming it's a problem with the MaKey. Is there any way around this? Either with the board or in Max?

are you expecting this to be real-time?

Sorry about that, yes I would like this to be real-time. I've read that this is where it can get quite complicated.

Real-time continuous output, adjustable with the rotary wheel.

Another option would be to get a PCM encoder and decoder IC set. Put your arduino in between. You would then take a sample of a second or two of audio and spit it out to the decoder faster or slower depending on the effect you want.

Thanks, that sounds about right I'll look into it.

Hi guys, I'm interested in creating an audio art project with the Arduino and an old rotary dial phone. I have little knowledge of how Arduino works (I've learned how to use a simple light sensor with Max/MSP and blink an LED), but I am asking here as I only have a month to create something.

My current idea is to loop the sound coming in through the phone's mic and use the rotary dial as a speed/pitch controller for the audio loop playing back through the phone's output speaker, all without the aid of a nearby computer. I have no idea where to begin so I would appreciate any advice or information regarding the feasibility and needs of this project.
