This is the fully built and complete unit, just plug and use.
Plus, get a FREE copy of several plugins to use with your controller: Wusik Station X, Wusik ST8, Wusik STX (DAW) and Wusik 8008.
4x4 USB MIDI Controller With RGB LEDs - USB MIDI Controller Using the Arduino Pro Micro (small Leonardo) ATMega32u4 Fully Programable with Windows, MAC and Linux direct support (no drivers needed). Just plug into the computer and use. By default it sends notes for each button.
Featuring:
32 x RGB LEDs (2 per button, on the left and right sides);
18 x Buttons (no matrix, so any combination of buttons can be detected); They are regular on/off buttons;
3D Printed Case and Buttons. Unit size: 15 x 15 x 20 cm (rubber feet excluded);
Windows, MAC and Linux USB MIDI HID Device Compatible (no drivers needed);
Windows and MAC App for customizing buttons, leds and also play audio loops. Using this app you can configure everything and save into the unit's EPROM memory;
Multiple options for setting the device directly: MIDICC, Note On/Off, Note On/Off Latch. Just press and hold both top buttons for a few seconds to enter the configuration swap option;
The unit also receives MIDI which can be used to set the RGB LEDs using note on/off. This is great for when you want to change LEDs with a sequencer or create your own App to handle LEDs. One particular note will turn on and off the unit handling of LEDs and will only react to input notes to set leds. Read more about this at the bottom of this page.
Keep in mind that this is a hand-made product with 3D printed case and buttons. I'm shipping from South America, so allow 45 days for delivery.
The extra rubber spray coating is only in black right now. It helps remove a bit of the 3D print tool marks and give a better handle feeling to it. It does peel if you scratch.
You can select the color of each piece of the case. Check the pictures for some examples. In the video below you have Top-Black, Middle-White, Bottom-Black, Buttons-White. Keep in mind that some colors are semi-translucid or fully-translucid. Check the pictures for reference.
Using MIDI Input to set the RGB LEDs:
On MIDI Channel 1 - Note:
34: enable LEDs using the internal configuration. Will still react to MIDI input, but will also override when you press a button;
35: disable internal LED configuration and only react to LED changes by using MIDI notes;
36: set all LEDs to white;
37: set all LEDs to Red;
38: set all LEDs to Green;
39: set all LEDs to Blue;
40: go to page 1;
41: go to page 2;
42: go to page 3;
43: go to page 4;
44: go to page 5;
45: go to page 6;
46: go to page 7;
47: flash all LEDs red (one time);
48~: set individual LEDs white;
64~: set individual LEDs red;
80~: set individual LEDs green;
96~: set individual LEDs blue;
On MIDI Channel 2 - Note:
36~: blink slow individual LEDs white;
52~: blink fast individual LEDs white;
On MIDI Channel 3:
Here you can set RGB values for each LED individualy, using 3 notes velocity. Each note velocity will set the RGB value of the LED. Translating the 0 ~ 127 value to 0 ~ 255 of the color. Notes 36 to 51 will set the R (red) channel. Notes 52 to 67 will set the G (green) channel and above will set the B (blue) channel and update the LED. The R and G channels doesn't update the LED. This way you can set any color that you want for each LED.
