The options are stereo, left and right. Similar to oscillator sample settings, if you tamper with these, it starts to show "custom". Used some of the generic features of go1.18, so had to update go.mod to require go1.18.
The RPC and sync library mechanisms were removed for now; they never really worked and contained several obvious bugs. Need to consider if syncs are useful at all during the compose time, or just used during intro.
The preprocessing is done sointu-cli and (almost) nothing is done by the NASM preprocessor anymore (some .strucs are still there.
Now, sointu-cli loads the .yml song, defines bunch of macros (go functions / variables) and passes the struct to text/template parses.
This a lot more powerful way to generate .asm code than trying to fight with the nasm preprocessor.
At the moment, tests pass but the repository is a bit of monster, as the library is still compiled using the old approach. Go should
generate the library also from the templates.
The main interface is render_samples function, which renders several samples in one call,
to limit the number of calls from Go to C. This is compiled into a library, which is then
linked and called from bridge.go.
