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.

Communication with X32 / X-Air consoles in C#

After tinkering with the SharpOSC library, I managed to set up a bidirectionnal connection with my Behringer X12 digital mixing console.

The orginal OSCSender / OSCListener class won’t work as we must share the same socket for sending and receiving OSC messages.

WaveDrom, a nice time diagram editor

A few days ago, I read an article on hackaday about a new time diagram editor.

It’s called WaveDrom, and it’s an online service. With a few lines of JSON code, you can draw neat time diagrams.

Here’s a picture of what I did:

YM2149 bus modes

And here’s the corresponding code:

Small Midi Development Board

Midi Development Board

I have sometimes to deal with some quick and dirty MIDI projects, and wiring a socket on a breadboard can be quite delicate because of the traction force from the cable. So, I’ve designed a small dev board who features a MIDI input (with its 6N137 active optocoupler), a MIDI output, and three RCA connectors.

YMWave – Revision B Schematics

The PCB files of this board revision are sent to the factory. This new version will include a mono switch and separate channel outputs. These boards should be error-free, and therefore sellable. 🙂

PCBs are here!

Today, I just recieved the first ten PCBs for my chiptune synth kit. The black solder screen looks really good. 😀
I’m now waiting for the last parts to make a prototype and to design its case.

YMWave Schematics

Here are my YM2149 Synth schematics.
Ten PCBs will be manufactured this month, as a first test. 🙂

No Arduino bootloader anymore, only plain avr-gcc code.

-Schematics removed, rev. B is available–

News about my YM2149 Synth

Hi,

I’ve got some messages asking me if I planned to sell a finished version of my YM2149/AY-3-8910 synth. The short answer is: yes.

I’m working on the PCB and the firmware of this synth. As I’m not going to sell thousands of it, it will certainly be sold as a ready-to-solder kit.

Schematics and software code will be public. 🙂

More to come!

YM2149 and MIDI

I’m still working on my YM2149 synth project.
