I think i noticed an improvement by adding these flags to the basic build
config...-O3 -mtune=cortex-a15 -marm -mfpu=neon
making some progress.... :)
just a thought... Is there any performance gains to be had by some how running
the synth in mono?
It also seems from what you said previously that the ram can be an issue...
This board only has 2GB so i'm working on pairing down ram usage.... I can turn
off the hdmi and gpu for example...
I wondering in some ideal future world something like KGPU, which enables the
gpu to be used for parts of ordinary processing, could be used to enhance
performance? I'm not using a display, so the gpu's going to waste....
Anyroad i'll keep plugging away...
next is designing a hardware interface....
Cheers for your encouragement and awesome patches....John

ok... I managed to compile the latest code on Debian jessie by removing the

I have an RT PREEMPT kernel running...
here are the specs of my
boardhttp://www.hardkernel.com/main/products/prdt_info.php?g_code=G143452239825&tab_idx=2
at the moment:
staccato notes seem to introduce a lot of xruns... also if i add a little
release to the amp envelope it seems to have issues....
my audio interface is a presonus 2x2
and my jack settings are 64 and 3
I found this
article....http://codesuppository.blogspot.com.au/2015/02/sse2neonh-porting-guide-and-header-file.html
Is this the direction i should look in?
I'm under the impression that i should at least be able to get 2 or 3 voices
reliably sounding with a modest amount of polyphony...The processor doest
seem to be loaded excessively during use....
I hope someone has some ideas.....
I also have an rpi3 i'll try out next.... Here's hoping
