Hi guys.
I got 1.3.9 to work quite well on a Rpi2.
I had some compile issues along the way, but that was sorted out with help from
this list. Here's the original thread with my questions:
https://www.freelists.org/post/yoshimi/Compile-errors-on-RPi2
It seems you found the same fix as me - the sse flags.
Don't know about polyphony. I used Yoshimi exclusively with my biphonic wind
controller, which uses two channels, but no polyphony beyond that, and which
controls volume by CC#2.
It worked, but took some tweaking of the setup with jack settings etc to get
good responsiveness in all situations.
My Pi was also running a hifiberry sound-card and an official pi touch display.
I'm not using the pi right now at all, as I'm currently experimenting with an
Axoloti for my sound-generation needs. Yoshimi runs on a laptop when I need it.
However, if it worked more than ok on my Rpi2 you should be able to get very
good performance with your Rpi3.
All the best to you in your pi-explorations.

ok... I managed to compile the latest code on Debian jessie by removing the sse
flags... not sure what this does to performance....
I have an RT PREEMPT kernel running...

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

I found this article....

For a work project, I am porting some PC code which makes extensive use of SSE

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
Cheers
