Hi,

I just installed Ubuntu Studio 18.04 lowlatency kernel 4.15.0-29 couple of days ago. I have a cheap Behringer U-PHORIA UMC22 USB audio interface and running that with these settings:

Sample Rate: 48000
Buffer Size: 512
Periods/Buffer: 3

Gives 10.7ms latency, works great with the VST instruments i use:

* AmpleSound Acoustic
* AmpleSound Bass
* Keyzone Classic, piano
* Stock Reaper Plugins and a bunch of free ones
* HoRNet plugins
* SForzando Soundfonts, like violin, cello, piano and other instruments

I do everything in MIDI these days and I get pretty good sound I might add. Good enough for me.

15-30 tracks with no errors so far, everything's is running smooth as butter.

I have a Lenovo IdeaCentre 23" All-In-One computer with 8GB RAM and a SSD 256GB. I might upgrade it to 16GB RAM in the future, but it runs well right now.
