I´ve just installed Ardour 6.3 on a raspberry pi 4 2GB running Raspbian Buster 64-bit (Debian), and managed to get sound from it with my midi keyboard connected via USB and the rpi4 onboard sound.
However, the latency is not as low as I want it, and when trying to change from 512 samples to the lowest possible, being 256, I get this message:
As you can see, I´m simply using ALSA, and I understand that using JACK will not improve anything on the latency parameter. I did try though, but Ardour crashes as soon as I select JACK.
So does anybody have any ideas about how I can make Ardour accept 256 samples, and perhaps even make 128 samples available?
Thanks in advance!
