Lo-Fi SAMD21 mini organ (ported from ESP8266) - new supported board by the Arduino synth library

In this video you will find a short demonstration of an update of my library, now supporting the SAMD21 (tested on Seeeduino XIAO).
Due to the reduced CPU speed (48MHz), the organ works without the leslie effect.
Also the MIDI performance is not the best but it allows building a very small organ.
There is no limited polyphony, but you will get unwanted noise with a too small audio buffer when playing to many notes at the same time.
The click noise is intentional (far from a realistic 9 switch key click).
The percussion function is also available.
I am using a sample rate of 22.05kHz and it is more like a low-fi fun project.
I would be happy to hear from you if you try out the organ on the XIAO.
