Configuration of the Kernel for sunxi-next defaults to Sequencer Support being disabled (At least for Orange Pi Zero). It should be enabled as a Module.
it is in:
> Device Drivers > Sound card support > Advanced Linux Sound Architecture
The Help for the kernel option goes on to say:
Which means that it should be enabled, or set as a module by default, and not disabled by default.
I don't know if the Allwinner support is there for HR Timers. But if they do support them, then the options:
"HR-timer backend support"
"Use HR-timer as default sequencer timer"
should also be set as Modules.
Under Generic Sound Devices,
"Virtual MIDI soundcard" should also be set as a module.
Interestingly, under USB Sound Devices, "USB Audio/MIDI Driver" is set as a module, as is "Behringer BCD2000 MIDI driver" and others. These will be useless without Sequencer support.
BRKL: If you want to help yourself, you should look at the instruction for building Armbian. Follow them through, its not too difficult, and you can build your own image and kernel with these options enabled, until such time as they become standard. (And maybe there is some valid reason why they have been disabled in the general case, in which case this may be your only recourse).
