If I want to use a hardware controller with a few buttons and knobs to control a sequence, what sorts of interface options do I have? MIDI, DMX, USB, etc.? A wired connection would be ideal, is that possible with the Pixelblaze or would I need to add something with WiFi in between?
You can send DMX channels to Pixelblaze (or even an Artnet signal) but it requires to be in Wifi and to install some software in between.
To be honest wifi is quite limited in terms of reliability and I would not recommend it in a crowded environment (phones, WiFi’s…).
I haven’t found any way to control patterns easily without adding myself a few buttons to the sensor board.
I’m currently working on a dedicated board and enclosure to allow this in an easy way (2 buttons and 2 thumbwheel) but it’s more aimed at small adjustments for wearables than proper live control.
