I decided to try 96 kHz audio with the S.R.O.
(Supermega Rumblic Organ), my slightly Aslan-like synth (it is not a tame device really),

1. At 96 kHz, schedtool definitely matters. Taking it out increased xruns a
lot. I tried to figure out what was interfering via htop, but it was very
unclear. So I'm keeping the schedtool for now. I could believe that if I
reengineer for a zero-X default setup (likely to happen in the future) this
problem might go away, X and the desktop certainly do have lots of demands.
I *think* the only big piece missing for me in this is keymapping, I use
F-keys to switch patches, quite easy in both LXDE and MATE.
thd .... otherwise known as trigger-happy-daemon ... does keymapping without X,
debian package is:
triggerhappy
Description-en: global hotkey daemon for Linux
Triggerhappy watches connected input devices for certain key presses
or other input events and runs administrator-configured
commands when they occur. Unlike other hotkey daemons, it runs as a
persistent, systemwide service and therefore can be used even
outside the context of a user or X11 session.
.
It can handle a wide variety of devices (keyboards, joysticks,
wiimote, etc.), as long as they are presented by the kernel as
generic input devices. No kernel patch is required. The daemon is
a userspace program that polls the /dev/input/event? interfaces
for incoming key, button and switch events. A single daemon can
monitor multiple input devices and can dynamically add additional
ones. Hotkey handlers can be assigned to dedicated (tagged) devices
or globally.
.
For example, this package might be useful on a headless system to
use input events generated by a remote control to control an
mpd server, but can also be used to allow the adjustment of audio
and network status on a notebook without relying on user specific
configuration.
.
Key combinations are supported as well as the hotplugging of devices
using a udev hotplug script; the running daemon can also be influenced
by a client program, e.g. to temporarily pause the processing of
events or switch to a different set of hotkey bindings.
