Controlling a Behringer X-Air console with a Wemos D1

The Midas MR / Behringer XR digital mixing consoles are cheap and powerful. With no tangible control surface doing quick and current actions can be inconvenient.

A Wemos D1 with its onboard ESP8266 and four PB-86 push-buttons (I like their vintage-looking style) are all you need to control your console on your WiFi network.

YM2149 and MIDI

I’m still working on my YM2149 synth project.

YM2149 sound generator, Arduino and fast pin switching

I spent my childhood with an Atari STe and its bleepy sounds. Recently, I purchased its sound generator on eBay: the YM2149 chip (made by Yamaha) or the AY-3-8910 (made by General Instruments).

I would like to make a chiptune MIDI synthesizer with it, but I thought it was a good start to play existing tunes.
