Hello,
This is about Jaki Liebezeit, drummer of the seminal 70s German band
Can, who passed away earlier this month. The piece was not made to
sound like Can. It was made with the 'thought of'.

Hi John,
I just saw your email to the LAU list and I would like to reply to it
but I couldn't since I was not registered to this mailing list. So I
have to create a new thread, sorry for the flood. :/
TL;DR: Don't worry about updating the Kernel, ALSA or anything. MIDI
over BLE is part of the BlueZ user-space and it is not released yet. So,
if you are too eager to try it out (I recommend), you have to build
bluetoothd yourself, check my blog for more information[1]. MIDI over
USB works just fine.
Technical stuff:
* The Bluetooth Low Energy support for MIDI is not in the Linux Kernel.
It is part of BlueZ's bluetoothd daemon, so you need to update BlueZ
user-space only. The thing is that it was not released yet, so if you
want the feature you have to compile bluetoothd yourself for now.
* The MIDI-USB is in the Linux Kernel, but you don't need to update that
since the drivers there are working for a long time now (thanks to
Clemens Ladisch and others). The changes for v4.9 I mentioned on my blog
impacts only the *gadget* driver only! The gadget driver is used for USB
devices (keyboard) and not USB hosts (your computer).
* You can ignore those pulseaudio errors on your log. That is because
pulseaudio tries to handle any ALSA Card that exports a PCM device and
since the MIDI device opens a new ALSA Card but it only exports a MIDI
device, it will fail to open it.
So, you can use your Seaboard RISE with USB just fine on Linux.
PS: How do you find using your RISE? Are you interested in having the
Equator synth and Dashboard applications on Linux? If so let me know, I
can arrange these for you (or anyone else). We, at ROLI, want to release
a beta version for Linux, it will be great to know if users are
interested in it.

Have any of you guys managed to get the kxstudio repositories installed on
a plain-jane ubuntu 16.10?

Can anyone recommend one of these that's reasonably small and robust - not
requiring a second mortgage!
I don't want keys, but programmable push buttons and sliders/knobs. A joystick
would be icing on the cake.
Thanks in advance.
Will.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
Hello linux-audio users,
I recently acquired a roland a-500s midi keyboard and I have problems
using it under linux. When I connect the device via usb, dmesg tells me
this:

Sorry, all I know about MIDI is how to connect cables, channels, program banks, patch sets. I have a vague idea that old-style MIDI cables had a max data rate comparable to telephone line modems.
Used to program on a C64. I wrote a Mandelbrot set generator in 6510 assembler. Had to turn off interrupts to get processing time down to many many hours vs the days it took in BASIC.
Fun times.

I would say so. It might help someone looking for a new soundcard.

Hello,
i own two soundcards which are supported by alsa without any problems
but are not listed in the supported devices in the wiki [1].
Question: Is it still interesting to list a device there or is it enough
information if the vendor tells the device is class compliant? The last
change was made 5 years ago...

I've been having fun with NetJack2 on Linux and a Windows slave which
also runs Ardour *. Just wondering if I can start 'netmanager' on the
Linux end within qjackctl options. I tried adding Server Suffixes
'-d net' or '-d netmanager', but I expect that shows my cluelessness.
All's well if I start it in a terminal with 'jack_load netmanager'.
(* I'm connecting to the Windows PC with Remmina RDC and my Cubase 8
won't run because it needs Aero theme. Ardour just works. Thanks again!)
