Hello,
I haven't been following this thread too closely, so apologies if any of
this is duplicate information.
The multiple core feature you are talking about can be set by passing
"-o synth.cpu-cores=2" to use 2 CPU cores. Back when I initially
implemented this, it did indeed provide for an inc
Hi again,
One idea, as the A20 is a dual core chip: FS has the option to use multiple
processors for synthesis (somewhere on the man page). I have avoided using
that option so far, because the docs say that it adds a little bit of extra
latency and I don't need a that much polyphony anyway.
But i

Hi Marcus,
I using this to generate pipe organ tones so my swell has 13 stops. I need to
play several or all voices simultaneously and that's why I am generating all 13
tones when a single key is pressed and control the stop ON/OFF by adjusting the
volume using cc 0 7 xx command.
Is this the co

Well, assuming you real
Hi Marcus,There is another thing which forgot to mention. I accidentally

Hi Marcus,
Thanks for the information and I was thinking of recompile the Sunxi codec and
the kernel too. I will do this.
Also is there any other way to use 13 voices simultaneously other than method I
am doing? Any suggestions?
Regards
Herschel

Hi Aere,
Thanks for your reply. I did create a file earlier but there was
no improvement. I'm not sure whether I re-started the machine. I will do this
again and let you know the how it goes.
I was actually suspecting "Requested 16 periods, got 8 instead" - can this be
the issue?
