Tim Alex Jacobs has created what he calls the "smallest and worst" USB MIDI synthesizer using the CH32V003, a 32-bit RISC-V microcontroller. Despite no competition for the title, Jacobs proudly showcases his creation, highlighting the affordability and uniqueness of the device.
A gamer named DOS Storm has found a unique way to play the iconic video game DOOM by using an electric guitar as a controller. By converting guitar notes to MIDI using a VST plugin and a digital audio workstation, the MIDI data is then converted to keystrokes that control the game. The result is an impressive demonstration of clearing level one using the guitar as a controller.
Simple DIY ElectroMusic Projects has released a complete DIY modular design for simulating the classic 80s Yamaha TX816 DX/FM modular digital synthesizer using a Raspberry Pi and custom PCBs. The design includes a user interface for four of the eight channels, a GY-PCM5102 I2C DAC, and MIDI connectors. The MiniDexed firmware running bare-metal on a Raspberry Pi allows for a compatible synth without breaking the bank.
