Re: Elk Audio OS on Pi 3&4 + HiFiBerry

I'm waiting for my Elk Pi Hat and Blackboard to get here! I'm mostly interested in developing things in Faust and couldn't seem to get past the glitches in Ubuntu Studio using a USB interface. I'm sure it can be done theoretically but it's a huge distraction. We'll see how the Elk thing works out. I...

Re: I just want a stable Linux desktop to develop and run Faust programs

OK, I'm still messing around with this old Macbook Pro. It is an A1278, using the i5-3210 (2.5 GHz) and 4 GB RAM. Generally speaking I can set the buffer to 512, 2 buffers, 48000 Hz sampling rate, and xruns/glitches are infrequent. It's fairly easy to get the CPU load too high. For example, using tw...

Re: I just want a stable Linux desktop to develop and run Faust programs

don't use jack-dbus, use jackd ( the old way) OK, I'm following this. The onboard audio sometimes gets detected as Pulse Audio but I have no intention of using it, just the USB Audio I/F. Does the advice in this article seem OK to you? https://we.riseup.net/nikgnomic/jack-can-live-without-d-bus

Re: I just want a stable Linux desktop to develop and run Faust programs

I'm still occasionally getting into a situation where, for example, I'm running a Zita reverb generated by Faust. Audio starts glitching/chattering. I close the Zita app. No change. I stop Jack. No change. I restart Jack. No change. I reboot the system. OK that helps, but wow, is there no way short ...

Re: How long do you need to finish a song?

Here's one that started as a bass riff 30+ years ago. I fleshed it out over the past 5 months. https://soundcloud.com/gary-worsham/salt-sugar-and-grease-tmi-on-the-bmi Here's one that came together on a family vacation last summer. It was 80% done in 4 days. I still need to tweak the mix a bit but i...

Re: I just want a stable Linux desktop to develop and run Faust programs

Hi @Digital Larry Ubuntu Studio (especially the recent versions) is set to optimize audio performance out of the box. You really don't need to change anything in the system. Ubuntu Studio is already set off. In fact the way to actually boost the performance and minimize the xruns, is to stop networ...

Rebooting didn't change the test result. It still works a lot better than before.

Re: I just want a stable Linux desktop to develop and run Faust programs

Thanks, it seems to be running better now. I did get a glitch over about 15 minutes but maybe with networking off that will go away. Only weird thing that happened is that all visible sign of QJackctl and my Faust apps disappeared, even though the processes remained. I'll keep plugging away at it. T...

Re: I just want a stable Linux desktop to develop and run Faust programs

Yes, I checked the audio settings in the Ubuntu Studio Control Panel and it's already set to "Performance". I'm also already on 19.10. I also see that the Jack setup in the Ubuntu Studio control panel is different from what QJackctl shows. Not sure how to deal with this. I am open to which...

I just want a stable Linux desktop to develop and run Faust programs

I have an old Macbook Pro, upon which I installed Ubuntu Studio 19.04. I'm really interested in using Faust to develop my own LV2 plugins (thinking about getting a MOD Dwarf to put in the effects loop of my guitar modeling preamp). However Mod Dwarf is on a Kickstarter that even before the current w...
