"This is a DIY project based off of FundamentalFrequency. It is similar to the Teenage Engineering OP-1.

An overview of the project can be seen here: [video above]

This was built by myself using a Raspberry Pi 4, 4GB w/64GB uSD card. It features the Tracktion Engine for its main software. All keys, encoders, etc. work and are housed in a custom 3D printed and laser cut acrylic case. Made some custom laser printed labels of which the "stop" key is rubbing off. I also compiled a custom version of the software where I added a Shutdown option to the settings menu which issues a proper shutdown command to the Raspberry Pi (avoids data loss and uSD card corruption). Also created custom Python scrips to save and load sessions. Also added on-screen keyboard to use with naming and loading the sessions. Works great with the touchscreen.

Some things this can do:
Tracks Screen
Plugins Screen
Drum Sampler
Step Sequencer
Drum Programming
Sampler
Bass Sequencing
Clip Cut/Paste
4OSC Synth
Adding Effects
Recording
Editing, Loop Controls, Saving, and Track Addition/Deletion
Mixer Overview
Pitch Bend
Modifiers

List of hardware included:
Raspberry Pi 4, 4GB
64 GB microSD card
45 keyboard keys (serving has synth/MIDI keyboard), controlled via a Teensy microcontroller
Hyperpixel 4 touchscreen (4")
Power supply

This thing works great and is really cool to create music with. Comes loaded with a bunch of samples and instruments."

Building and Playing the LMN-3 DIY Open Source Synthesiser

"The #LMN3 #raspberrypi #synthesizer made quite the splash in the media some weeks ago. In this video, I build it and explore the DAW a bit (there will be another video focussing on that). Is this really an "OP-1 - killer" that some on social media make it out to be? Table of contents:
