Yes, it would be a compile for ARM pi-core mostly.
But it would be very good on both x32 and x64 (x86)
That "Non Daw" daw allows VST plugins and full ecosystems to run even
on a pi-zero. Things like VST soft synths as listed below. (arm compiled)
i found some more important powerful tools below for Raspberry Pi DAW work.
(it would be amazing if the tools below could also be compiled for tinycore ARM pi-core
and x86)
The links below are running the tools under the standard Raspbian OS on pi.

There are already several very high level free DAWS for the Raspberry pi.
0) "Non Daw" Daw on ARM for pi ( pi zero board)
supports VST's and ecosystems (LV2, DSSI, LADSPA)
1) "Waveform Free" Daw for pi (by tracktion) on ARM (pi 3 or 4 board)
2) "Ardour for pi" Daw (pi 3 or 4)
3) "Reaper for pi" Daw on ARM (pi 3 or 4)
