When Wireless MIDI Has Latency, a Hardwired Solution Saves the Day
1 min read
Summary
Moby Pixel created a MIDI controller twice, once with an ESP32 and once with a Raspberry Pi Pico, to see which microcontroller was best for the job.
The MIDI controller has a 4 x 4 array of arcade buttons that are wired to the microcontroller to send MIDI data to other devices.
The ESP32 version had intermittent latency spikes, while the Raspberry Pi Pico’s hardwired setup eliminated this issue.
While there may be solutions to the latency problem with the ESP32, the Raspberry Pi Pico’s faster performance with a hardwired setup makes it a more accurate and low-fuss option.
The controller’s case is made of wood with a graphic wrap, making it a stylish and functional device for sending MIDI events.
