win: arturia midi control center <-> beat step pro

by Atte

Hi I have an arturia beatstep pro, that unfortunately needs a win/mac-only sofrware, midi control center (mcc for short) for a USB midi connection to upgrade firmware, even change settings and save projects. Previously I ran win7 in virtualbox, but today I tried running mcc through wine, and it worked. Almost. It doesn't recognize the beatstep pro. In windows it works like this: If the beatstep pro is connected (USB) while the mcc is running, the beatstep pro boots in a special "update" mode ("upd" in display) resulting in it getting a different device name, which I suspect is what mcc is looking for. The beatstep pro can be forced to boot in update-mode by pressing, record+play+stop while powering on, which changes the name: normal mode: atte@pandrup:~$ aconnect -io| grep BeatStep client 20: 'Arturia BeatStep Pro' [type=kernel,card=1] 0 'Arturia BeatStep Pro MIDI 1' 1 'Arturia BeatStep Pro MIDI 2' update mode (as is the rest of the output): atte@pandrup:~$ aconnect -io| grep BeatStep client 20: 'BeatStepPro Updater' [type=kernel,card=1] 0 'BeatStepPro Updater MIDI 1' atte@pandrup:~$ ll -t /dev/ | head total 0 crw-rw-rw- 1 root tty 5, 2 Sep 1 22:57 ptmx drwxr-xr-x 2 root root 3.3K Sep 1 22:56 char crw-rw----+ 1 root audio 14, 25 Sep 1 22:56 dmmidi1 crw-rw----+ 1 root audio 14, 18 Sep 1 22:56 midi1 drwxr-xr-x 4 root root 320 Sep 1 22:56 snd crw-rw---- 1 root tty 7, 7 Sep 1 22:50 vcs7 crw-rw---- 1 root tty 7, 135 Sep 1 22:50 vcsa7 crw------- 1 root root 244, 1 Sep 1 22:50 drm_dp_aux1 crw------- 1 root root 244, 0 Sep 1 22:50 drm_dp_aux0 The devices char, mmidi1, midi1 and snd appears at the same time as the beatstep pro is plugged in, so I guess either dmmidi1 and midi1 are the ones to target. atte@pandrup:~$ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 006: ID 0bda:0129 Realtek Semiconductor Corp.

Can I change anything in wines configuration? Could anything else be done to make mcc in wine see the beatstep pro midi device? Thanks in asvance... -- Atte http://atte.dk http://a773.dk

I think there is some disagreement over whether hard RT is needed for audio work. I think hard RT is meant more for systems running manufacturing hardware. My systems work just fine for audio work using Debian's and KXStudio's -rt kernels. Is KXStudio's kernel hard RT or low-latency? David W.

limits.conf nice rtprio

by Jaromír Mikeš

Hi, I am afraid that I still don't understand limits.conf file properly. Hopefully someone can explain me some details. I have limits.conf file like this: @mira - rtprio 99 @mira - memlock 8000000 @mira - nice -10 @mira /usr/bin/jackd nice=-1 rtprio=85 @mira /usr/bin/qjackctl nice=-1 rtprio=84 @mira /usr/bin/ardour nice=-1 rtprio=83 @mira /usr/bin/hydrogen nice=-1 rtprio=82 @mira /usr/bin/jackeq nice=-1 rtprio=81 @mira /usr/bin/jack-rack nice=-1 rtprio=80 . . Should I do something better with nice and rtprrio values to ensure better RT robustness ? There is also possible add "priority" value in limits.conf file ... Should I use it? 2nd question: In qjackctrl Settings -> Advanced ... there is a "Priority" option ... How it is connected with these above? Should be used? mira

It might be something similar absurd. I have heard that many wifi drivers can block interrupts when scanning for signals. I would try disabling wifi and see if it helps. David W.

Debian 9 - Xrun

by list

Hello. Just installed a brand new Debian 9. Running Jack from debian's package - 1.9.10+20150825git1ed50c92~dfsg-5 Star Jack with Qjackctl. I get Xruns, or to be clear i get 1 xrun by hour (!) The same if i leave the computer on, and leave it without any sound application open/running, or browser or whatever. Just booted, start jack/qjackctl & wait... So i see nothing in the journalctl (or message/kern.log/syslog ) something that could make it append at the same time/hour the xrun appear. No matching time. Running a «vanilla» kernel - not RT Tried with 3 different USB cards, same thing. I'll try to build a new kernel more low latency oriented to see. In the meantime, if anyone on the list have any idea...i'll be happy to listen. All the best !

How to play multiple bluetooth (BT 4.0) audio receiver ?

by Winfried Ritsch

Hello, I just did some research but couldn't find any satisfying answer and I am not an BT specialist. So before digging deeper in the BT-world I want ask here if anybody already has an solution and if it could work theoretically ? Here my state of research: Since BLuez >= 5.0 dropped ALSA [1] I tried using pulseaudio (can route it trough jackd). I connected a BK8000L module (sure hifi) via bt-manager and pulseaudio works fine. I try to connect a second, the first one gets disconnected so only one is audio device seems to be possible at the same time. As a second solution I tried the alsa implementation: bluez-alsa [2], but I didn't succeed to use it via jackd (didnt try hard) and it has the same behaviour with aplay on an first try on command line. Any ideas are appreciated. mfg winfried Purpose: simple distributed audio-system adding BT speaker for sound installations, the first try two BT-Speaker used each mono, forming a stereo pair.

Linux Synchronization of multiple audio channels e.g. for exact processing of ( timing ) differences between channels

by cuhl＠eit.uni-kl.de

Hello to users of the various Linux sound systems! I have a rather technical question regarding the implementation of multichannel recording and playback : Is the relative alignment of different channels exactly constant? I mean, can I reliably assess ultra short differences between multiple channels, e.g. if one channel's signal is a delayed signal of another channel by about 700 ns and I want to calculate the exact delay of the signals relative to each other? I'd also need to pass exactly timed signals to the outputs. Internally for the inputs and outputs I would probably choose a platform with I2S, but other embedded protocols would be alright too, if I can match them to the ADCs chips outputs and DACs chips inputs. So what I need to know is not about the delay from input to output, but rather how well and exact the synchronization of multiple channels works. I would be happy about hints and answers. Regards Christian

[ANN] Vee One Suite 0.8.4 - A Late-Summer'17 release

Greetings! The 'Vee One Suite' of old-school software instruments, respectively synthv1 [1], as a polyphonic subtractive synthesizer, samplv1 [2], a polyphonic sampler synthesizer and drumkv1 [3] as yet another drum-kit sampler, welcomes a brand new and fourth member, padthv1 [4] as a polyphonic additive synthesizer, now joining the late-summer'17 release party.
