Hi. Amazingly after emerging alsa-lib, alsa-utils, and alsa-oss, running
alsaconf, and pushing up the master volume in alsamixer, the sounds worked
OOTB. I had to add snd-seq-midi to /etc/modules.autoload.d, as it hadn't
autoloaded at bootup. The problem is that even though the midi keyboard shows
up in /proc/bus/usb/devices, it does not show up in Qjackctl's midi connect
bay. Tried modprobe snd-usb-audio, but it complains that there is no such
module. As shown below, the kernel config shows snd-usb-audio there, but
commented out. All relevant info further down. Nigel.

/etc/hotplug/blacklist. But I don't think there's anything here that could
cause a problem.
# Listing a module here prevents the hotplug scripts from
loading it.
# Usually that'd be so that some other driver will bind it instead,
# no matter which driver happens to get probed first. Sometimes user
# mode tools can also control driver binding.
#
# Syntax: driver name alone (without any spaces) on a line. Other
# lines are ignored.

Thats all folks. Any suggestions apart from "Reinstall the OS" welcome.
