DIY platform for building MIDI controllers

Postby paradajz » Fri Jun 08, 2018 8:56 am

Hi,

OpenDeck is a project I'm working on for quite a while now which enables users to create MIDI controllers with ease. Entire platform is open-sourced and it supports different hardware, including Arduino and Teensy boards. Source and schematics can be found here: https://github.com/paradajz/OpenDeck

Official OpenDeck board features the following:

* 64 digital inputs for buttons (or 32 inputs for encoders)
* 48 PWM outputs for LEDs (16 RGB LEDs are supported or 48 single color LEDs)
* 32 analog inputs for potentiometers or FSRs
* DIN MIDI in and out connectors

Additionally, some Arduino and Teensy boards feature OLED/LCD display support.

Everything is configurable in Web interface which is also open sourced (in OpenDeck repository).

As far as actual features are concerned, OpenDeck is full of them. Here's a short list:

* Configurable MIDI channel for every component individually
* Configurable latching mode on buttons
* Support for RealTime and MMC messages
* Selectable CC range
* Selectable velocity for buttons
* Selectable encoder/potentiometer direction
* 7-bit and 14-bit NRPN support
* Daisy-chaining multiple boards
* Much more here: https://github.com/paradajz/OpenDeck/wi ... e-features

Currently, work is on the way to allow firmware updates directly through web interface.

Cool idea, thanks for sharing. I only see prices listed for the board itself, but that doesn't seem to include any components to use with it. Is that correct? If so, I presume this is designed to be used with third party components? What are the estimated costs for a fully built controller with this? What about with casing?
I heard FLAC and I haven't gone back.

Correct.

Well, that really depends on your sources. Potentiometers/encoders are usually priced 1€ per unit. Buttons... I don't know, you can order hundreds of small tactile buttons from eBay for a few bucks. Same for LEDs. I like silicone buttons from Sparkfun, for instance. Genuine Sanwa arcade buttons are more expensive.

I have a local guy who makes great-looking wooden cases (see this image for instance). You could also re-purpose some other plastic casing or 3D print your own. Lots of options really.

I'm also building complete, custom controllers on demand.

I'm impressed, Paradajz! How many custom controllers have you built so far?

Sorry for the late reply!

I don't know actually. My latest one is called Bergamot and it's based on touchscreen.
