RFC on architecture for MIDI piano practice tool for blind/low vision/elderly users.

I'm working on a recording solution for my technophobic father for X-Mas,
and just wanted to see if this seems like a reasonable high-level
architecture to more experienced people:

(a) midish or amidirecord (which would be better?) continuously records the
MIDI output of a digital piano to a compressing file system - I'm thinking
BTRFS - https://btrfs.wiki.kernel.org/index.php/Compression - say one file
per day.

(b) Configure Rhasspy - https://rhasspy.readthedocs.io/en/latest/ - to be
able to feed MIDI back to the device via midish, so it gets played,
initially in the simplest way possible, e.g. by speaking things like "Play
2020 12 5 at 1 15 pm" and "stop". (My dad doesn't have or want internet
access, so need to avoid any STT that sends voice offsite for processing.)

(c) Over time, improve the interface, for instance, to allow the user to
give arbitrary names to start points. Perhaps also add the feature of being
able to choose between sending the MIDI back to the device and playing via
some nicer-in-some-ways instrument via linuxsampler and the appropriate
.gig files.

Any thoughts?

Thanks,
