In this video, I’m testing the Seeed Studio XIAO MIDI Synthesizer: 🔗 Product link: I’m running a custom firmware that includes: - live play - MIDI file playback from littleFS (standalone — no computer needed) - a lightweight sequencer I’m using my MIDI controller, connected via a custom adapter with an opto-coupler to the ESP32C3 UART. This setup allows the device to receive MIDI signals. You can play music, change instruments (programs), and control MIDI parameters. The MIDI file player uses LittleFS for file storage and you can use the LittleFS upload to play your own MIDI files. It supports: - standard MIDI files (Format 0 and Format 1) - RIFF MIDI files (RMI) Some meta events are ignored, but all regular MIDI events are sent to the SAM2695 MIDI chip. Features include: - tempo control - mute individual tracks - play live along with MIDI files - change effects, volume, and more The sequencer is a lightweight version based on my earlier project. The metronome uses the drum channel to create the click sound. You can: - define a custom count of clicks before recording starts - set the sequence length (it switches to loop playback afterwards) - record overdubs (shown in the video) - enable quantization (used in the final part of the video) 👉 Note: To avoid copyright issues, I removed many recorded MIDI files. Feel free to request a demo — I can upload short examples to YouTube Shorts or Instagram. This video was created entirely by me, with no editorial influence from Seeed Studio. --- Other projects: 🔗 GitHub: 📸 Instagram: 🐦 Twitter: 💬 Discord: (if the link doesn't work, please check the description of the latest video) 📧 Email: mailto: @ --- I appreciate your support!
