Re: [PD] dimmer from pure data

What kind of load do you need? The Krida you linked to one has 2A per channel. http://www.inmojo.com/store/krida-electronics/item/8-channel-ac-light-dimmer...

If you need more, this one has 4A per channel, but you need two of it to reach 7 channels. More expensive, but no high voltage work required. https://www.thomann.de/de/botex_mpx405v.htm

    I guess it does the job.


It will only switch things on and off, not dim them. For that you
want something with triacs or scrs like this:

        and there are "DMX interfaces" that present themselves as
        MIDI devices
        (either they have MIDIin and DMXout; or they show up as MIDI
        devices
        when connected via USB)
