BlueFruit Playground Express - Mutipl Sounds

by joevargas on Sat May 08, 2021 8:31 pm

I'm completing the Glowing Bottle Castle and Capacitive Touch Piano project using the BlueFruit Playground Express.
https://learn.adafruit.com/glowing-bott ... ouch-piano

I got it working when I press one key at a time. I'd like to play chords where multiple keys can be pressed at the same time with their corresponding sound and LEDS lit simultaneously.

Can this be done?

TIA

You may have to switch to C++ to do polyphonic sound. I don't know if the nRF52840 is supported, but have a look at https://learn.adafruit.com/synthesizer-design-tool/audio-system-design-too as a place to start.

It may be possible in CircuitPython. I suggest digging around at https://learn.adafruit.com/ for audio projects using CircuitPython.
