Why only 24 voices on faster Pis? #25

Closed Kirtai closed 1 year ago

I'm curious why the Pi3 and Pi4 have the same polyphony as the Pi2.

Just simplicity or something else?

This is for simplicity. You can increase the number of voices per core here. Because there are 4 cores you will get a total number of voices of 4 times this value.

By default MiniSynth Pi runs at only 600 MHz on the Raspberry Pi 2-4. You can add the option fast=true to the first line of the file cmdline.txt on the SD card to run it on the maximum supported speed. On the RPi 3 and 4 this may require a head sink and/or fan.

Ah, thank you.

Nice that it can be expanded if necessary :)
