Hi! I have a fairly complex patch in MOD-UI and I’m getting occasional spikes to 100% CPU usage. Usually it’s around 70% and the CPU temp hovers around 64. I’m also getting a red warning symbol on my Zynthian screen. I suppose these are connected. The Zynthian Wiki doesn’t include pictures of the different warning flags, so I don’t know what the flag actually means. It’s a red triangle with an exclamation mark if I’m reading it correctly. Any idea what could be going on? My Zynthian is a hodgepodge I built half by accident, but maybe it’s a software issue.
I’m running four MIDI Channel Filters, four Dexed, four ChorusI, four ArgotLunars, a disabled 2x2 Gain, and Invada Stereo Phaser, a Calf Tape Sim, Reverb, Exciter and Bass Enhancer and an enabled 2x2 Gain.
Stupid question: What’s an XRUN?
Considering I’m using a power bank, PSU problems wouldn’t be very surprising. I really would like to get this working with a power bank, though, and it should be new and decent. I guess I should find a way to power the screen separately.
It basically means that the CPU can’t keep up with all that you’re trying to do. The “X” refers to both under- and over-runs. See this article for more.
I still get the same spikes and flags with the official PSU that came with my Raspberry Pi 3B. Am I just asking too much? Any idea why they are random spikes instead of having anything to do with what I play? And why it would hover at 70% most of the time.
I also get spikes if disable every pedal and stop sending any MIDI to the device.The average CPU usage drops to around 64% with nothing going on.
