    Just want to let you know that it worked fine, all there was to do was to load the firmata code from the arduino menu and launch the pd patch from purr data. I used the "firmata basic" I think. Thanks for you help. :)

    @alexandros hey thanks for getting back.

    The eight relay board that I got supposedly requires more power than the arduino can reliable supply, I guess this is due to them being mechanical. It is solved, I cut up a USB cable today and it works fine with the arduino. Flashing and switching. :)

    Next step is to hook it up with Pd, I will try tomorrow to follow the tutorials I have found.

    Ok, I might do it like that, use a USB charger. Using multiple power sources can introduce problems sometimes though. But as of now this might work.
    I was looking at this guide: https://www.open-electronics.org/the-power-of-arduino-this-unknown/

    I got the impression that the arduino will forward the external power through the Vin pin.

    Thanks.

    I got this one: https://goo.gl/images/KZJsUy

    I think I will try to find a power supply of maybe 12v and connect it to the arduino, and then give the relay power from the arduino board pins.

    It's nothing specific that I do not trust, just in general it can be a sign that somethings is abandoned if it is not recently updated. Updating firmware when you are not sure what you are doing can be bad, for one thing.

    Aside from pd and arduino, connecting the relays to the arduino feels a bit scary in terms of power handling. The relays seem to want more power than the arduino can supply. Then I got the impression that you can not just connect any old power supply else it might fry.

    :/

    Hi, I am looking for basic gudie(s) to set up a macbook w/ pd, an arduino uno, and a board with 8 relays.

    The ones I find are very old, from 2011, and I do not want to make any mistakes so to damage the boards.

    Thankful for help.

    Thanks! I may see if I can use Processing together with Pd instead.

    Hi, I would appreciate some help on where to find info on how to set up this. Sorry if I post in the wrong spot.

    I got a collection of old usb webcams that I would like to connect to pd. Initially I only want to grab the camera streams. Is there a tutorial that I could follow? I am hoping that there already is a library in Purr Data and an object I can use.

    :)

    Thanks a lot!

    Still on to this...

    Is it possible to get fair results with [autotuned~]?

    I am not able to control it further than pitch shift. When clicking the message boxes containing the different scales I can still play chromatic lines. I made a few test messages with just 12 0's'or 1's which I'd figure would make a drone note, but the result sound pretty random. It seems that it always try to repitch notes B and C, no matter what scale you have selected. I can not figure out how you set the root of the scale.

    If it is just me that doing the wrongs and the patch actually is working, can someone please tell me how to use it?

    lead's autotune(vocoder).pd I can not get to work "error: signal outlet connect to nonsignal inlet (ignored)" and it is too complex for me to work out, the in_ADC/out_MIDI window.

    I found a few other patches that I can try to stitch together if I can not find a complete working patch. They are and audio to midi patch, and a midi to audio patch.

    I'd like to ask for an opinion on a good solution for what I am trying to do, to make sure I am looking for the right solution in the right place:

    I want to be able to decide what pitches are affected or bypassed, and all affected notes should be possible to be transposed by the same amount. Normal.

    As for tone, realism is not important but it should not sound "destroyed" by default (ugly artifacts), and I actually want to have the wobbling between notes when the algoritm can not decide where to go.
    So formant "truly correct" is not essential, solid basic functionality is more important.

    Is there a better solution for this somewhere?

    Thanks a lot!
