Hey hey, I haven several MIDI devices plugged in either directly as USB MIDI devices or using a USB-MIDI cable. They ae plugged into hubs, if that is important. Now when I connect them through the ALSA seq API, I sometimes get notifications lilke these, printed on every console, if I change: [1354175.824801] usb 1-4.1: urb status -32 The ID in brackets changes. Any idea what this is and how it can be fixed? I have seen that this is some kind of general USB kernel warning, but haven't been able to find a solution, yet. Thanks for any help and best wishes, Jeanette -------- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s But now I'm stronger than yesterday <3 (Britney Spears)

Microphone advice

by david

Good evening! I currently don't have a microphone of any sort. I don't generally do a lot of audio recording, but I do sing (sort of), play a Garcia Concert Model 3 nylon string classical guitar, and occasionally do silly things like play my collection of wind chimes ... So - what would be a good, reasonably-priced mic for those uses? Thanks. -- David W. Jones gnome(a)hawaii.rr.com authenticity, honesty, community http://dancingtreefrog.com

New Computer

by Will Godfrey

Today I finally took delivery of a new computer for my music, to take the place of the old one that was showing real signs of stress. The new one is custom built by Scan (UK). It is in a 4U rackmount case and has an AMD Ryzen 5 1500X processor, on an ASUS motherboard and with a Radeon R5230 fanless graphics card. Audio I/O is via an M-Audio Mtrack 8, and MIDI via a Prodipe 4i/4o. That graphics card was a significant problem, as it was difficult to get hold of one, but it was worth the hassle. The machine arrived quite early this morning, extremely well packaged. They had even put bubble wrap inside for additional shock protection - with a very clear warning on the top! Looking inside it has been very neatly assembled, no random loose wires. I added a CDROM drive I already had, and a second SSD, both of these robbed from the older machine. The SSD has all my working project files on it. I installed devuan Linix 2.0.0 rc without any issues at all - no more inexplicable SystemD failures. I then built up the system with all my favourite programs. This was the most time consuming part of the install. And the performance? Stunning! The machine is totally silent. There wasn't so much as a whisper when maxing out all 8 cores compiling the latest Rosegarden image! One of my most complex projects had to run at 5.33mS Latency on the old machine, and I didn't dare touch anything while it was going. On the new one I can run it at 1.33mS, and shuffle various windows around without a single Xrun. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

ZFS?

by Peter Lutek

greetings, all! wondering if anyone has experience using a ZFS raidZ2 disk pool for audio. i'm talking about a LOCAL pool, running on ZOL (http://zfsonlinux.org/) -- NOT a LAN-connected dedicated server. here's an interesting test case, which seems to show entirely adequate throughput for multichannel audio applications: https://bit.ly/2ryO9xr (that's with openZFS on freeBSD, but i'm assuming performance should be similar on linux) looking forward to any thoughts y'all might have on this! cheers! .pltk. -- Peter Lutek - improvising musician in Toronto, Canada http://peterlutek.com

Re: [LAU] RME UFX Class Compliant Mode Duplicated Channels

by Mirko Horstmann

There are two modes to chose exactly that: "22 Ch." and "Phones". Phones will duplicate channels as you describe, 22 Ch. will do a 1:1 routing. Mirko Am 9.
