RME Multiface with cardbus interface & cardbus-ExpressCard adapter

by Iain Mott

Hi list, I'm trying to find a way to use an RME Multiface mark I with an old RME cardbus interface. My laptop doesn't have a cardbus slot but has an ExpressCard slot. I've read old threads of people successfully using the cardbus interface with a cardbus-ExpressCard adapter on Windows. Has anyone done this on Linux? From what I read, what's needed is a an adapter that requires no drivers. Thanks, Iain -- _________ Iain Mott http://escuta.org

Re: [LAU] Focusrite 18i20 vs Behringer FCA1616/UMC1820 - Was: PreSonus 1818VSL vs Focusrite 18i20

by Ralf Mardorf

Hi Olli, thank you very much. On Sun, 4 Dec 2016 15:39:55 +0100, Olli wrote: >I haven’t adjusted any IRQ settings, just some minor, usual tweaks for >Arch Linux. Let me know if you want to know any additional details or >if I should run any specifc query! Usually I'm interested in MIDI jitter, but in this case there's no need to run alsa-midi-latency-test for me. There are just two other things I wish to know. 1. Are you using a first or second generation 18i20? I read that for the second generation, there should be issues related to the mixer. 2. Do I understand correctly, 64 samples cause more latency than 128 samples? >48 kHz, 256 samples, 2 periods: >detected roundtrip latency: 1389 samples (28,938 ms) >systematic latency: 621 samples (12,938 ms) > >48 kHz, 128 samples, 2 periods: >detected roundtrip latency: 1239 samples (25,812 ms) >systematic latency: 471 samples (9,812 ms) > >48 kHz, 64 samples, 2 periods: >detected roundtrip latency: 1240 samples (25,833 ms) >systematic latency: 472 samples (9,833 ms) > >48 kHz, 256 samples, 3 periods: >detected roundtrip latency: 1389 samples (28,938 ms) >systematic latency: 621 samples (12,938 ms) > >48 kHz, 128 samples, 3 periods: >detected roundtrip latency: 1287 samples (26,812 ms) >systematic latency: 519 samples (10,812 ms) > >48 kHz, 64 samples, 3 periods: >detected roundtrip latency: 1390 samples (28,958 ms) >systematic latency: 622 samples (12,833 ms) Regards, Ralf

Is QMidiArp broken?

by Yassin Philip

Hi all! This morning I can't seem to get QMidiArp working. The custom UI isn't available anymore, for starters. No "Edit" in Qtractor's menu, only "properties" witch would not be a problem (on the contrary, I like generic UIs) if it was working :/ Note that there does not seem to be a way to write patterns, like in the custom UI, the text field for that is not present in the generic UI. I'm used to QMidiArp, I've been using it for years, I know that you have to tell him the MIDI channel ins and outs and such, but still, no luck. I tried building it from source, that went pretty well, now I'm pretty sure I have the last version installed, but still no luck. Qtractor : 0.8.0.4git.415519 Qt 5.5.1) QMidiArp : 0.6.5 (That's what the standalone version says, the LV2 plugin doesn't display any version) Can somebody confirm that? This sad state of affairs is ruining my day :( yPhil PS -wait, it's working (both UI and actual arpeggio) in the current Qtractor build (0.7.9, Qt 4.8.7) so it's obviously a Qt problem ; is there something I should tell to either Qtractor or QMidiArp build script to get them to play together? -- Yassin Philip - New album out NOW http://yassinphilip.bitbucket.org

Recording in 96K on Linux / Raspberry Pi with Sound Devices USBPre2 Interface

by davidkamp

Hi, I am trying to built a Raspberry Pi based 96K audio recorder for scheduled WAV recordings. Has anyone successfully made 96K recordings on PI / Linux with the USBPre2? https://www.sounddevices.com/products/portable-audio-tools/usbpre2 If yes, any experiences on what to watch out for? The manufacturers could not tell if it will work. In their description it only guarantees to work on linux up to 48K. Also i'd be interested if anyone had good experiences on Linux / PI with other USB Audio Class 2 devices and high sample rates. Thanks very much for any tips!

Synth perc sounds howto

by Yassin Philip

Hi List! I'd like to reproduce the percussive sound that can be heard used as some sort of "snare" in this video <https://www.youtube.com/watch?v=KQcI7oKE1pc>, you know the "marble on a glass table" thingie? I'm guessing it's a typical subtractive analog synth sound (with a special reverb, apparently) so maybe there can be a way to approximate it using our arsenal, maybe SynthV1 or ZASFX? Thanks for any pointer, yPhil -- Yassin Philip - New album out NOW http://yassinphilip.bitbucket.org

Ardour 5¹ font size - ¹from Arch User Repository

by Ralf Mardorf

Hi, I try to use https://aur.archlinux.org/packages/ardour5/. Ardour 5 copied the Ardour 4 settings, but I get nearly unreadable small fonts and no bright theme is available. The short cut for zoom in "=" doesn't work. The theme "Blueberry Milk" is missing. I'm not against dark themes, but all provided dark themes at least in combination with the much too small fonts, provide much too less contrast. Im using a CTR 1152x864, no unusual DPI settings, with relatively dark brightness settings. The only question for the moment is: How can I enlarge the font size? By default the Ardour 4 fonts were to small, too, but I at least could read enough, to find where to enlarge the fonts. $ pacman -Q ardour5 ardour5 5.5-1 Regards, Ralf
