So, I was doing a few tests on a barebone openbox environment lately, and I decided to just quickly banchmark how the standalone Pianoteq executable works on my system under jack.
My system is configured to heavily prioritize USB audio. I did not change the conf, just tried a few things.
Conditions: Kernel Realtime, Openbox + compton.
When using my laptop's audio card: ALC269VB Analog:
I can play nicely up to 15 notes simultaneously with pianoteq before triggering any xrun with this setup: 48kHz, 3 Preiods/Buffer, 256 frames. Any lower latency is unworkable.
When using by UMC202HD: I can get as low as 48kHz, 3 Preiods/Buffer, 128 frames. Any lower latency is unworkable.
I configured my system for audio a lot of time ago, so maybe there are few things I would have to tweak again, but seem like 128 or 256 frames is around as good as I can get.
I started digging around and run a few tests. One of my favourite vsts is Pianoteq, which I use since forever. The funny thing is , if i run pianoteq standalone , not as a plugin, i have EXTREMELY DIFFERENT RESULTS, (and very weird as well). THe resulsts are:
If i run Pianoteq standalone with jack , i have pretty much the same issues i have in bitwig. If I run it with Alsa instead, i can play even setting it a 64 SAMPLES!! and NO CLICKS Whatsoever!!
Maybe I glimpsed over it somewhere else, but I was wondering: would it be workable for you to just use ALSA then? I am reading more reports about people being happy with that lately, as for example here
. I might give it a spin too!
