I would like to create a certain setup. I am running Archlinux on a Lenovo P15 Gen. 1 and bought an used Roland Rubix22 Usb Audio Interface in which I would like to put in my guitar setup an amp simulator like Guitarix and then hear the music I play on my guitar from the speakers of my notebook or through some headphones.
I installed the pro-audio package group which includes all necessary packages like jackd, guitarix and a lot more stuff (I provide the link to the package group if you are not sure whether I have a certain package. I replaced jackd with jackd2 since most tutorials I found have been written with jackd2 in mind. (And 2 sounds better than 1)
I also have qjackctl installed. In qjackctl I chose as Output Device: hw:PCH and as Input Device hw:Rubix22,0. Channels and Latency I/O is set to default. (My current latency is at 42.7msec, which is something that should maybe fixed later on first I would like to connect my guitar to the 1L instrumentcable port of my USB Audio Device with enabled Hi-Z and here something on my speakers when I pick a string. In most of the tutorials peoples started to connect lines in the Graph or Patchbay window (not sure) I didn't since first of all no devices will be shown there and I also would have no clue what I am actually doing.
I just started guitarix afterwards which prints an error message:
Code: Select all
system init *** mlocalall failed:
system init *** failed to lock memory: Cannot allocate memory
system init *** failed to lock memory: Cannot allocate memory
PitchTracker *** error creating realtime thread - tuner not started
Primary Goals
- create a setup that takes my guitar sound as input and outputs it to my speaker
- reduce latency
- understand how to setup sound settings and amp simulations in guitarix to create some decent sound
