# Questions
## Do you have any thoughts on generating scores in chant notation (neumes)?
-
I'm not familiar with typesetting chant notation, so I suggest reading
this specific section of the manual for information.
## Do you use this to compose or to write up compositions&#x2026;?
-
No and yes. I use pencil and paper to compose the first draft. Then I
move to Emacs to input the notes. Either way it's certainly possible
to compose from Emacs directly, especially if you're doing this
programatically, so I guess it depends on what you're trying to do.
-## Can one use MIDI/USB instruments (like keyboards) to input Lilypond? For example for note heights?
+## Can one use MIDI/USB instruments (like keyboards) to input LilyPond? For example for note heights?
-[Don't know about emacs, but Frescobaldi supports MIDI input.]
+[Don't know about Emacs, but Frescobaldi supports MIDI input.]
There is a package called `midi-kbd` which creates keyboard events
from MIDI input, so I believe the answer is yes, but I don't own a
MIDI device, so I haven't tried it.
## Did you ever write huge scores (BigBand/Orchestra) in Emacs?
-
Never, but that's certainly possible.
-## Is there a decent OCR for handwritten music→Lilypond?
-
+## Is there a decent OCR for handwritten music→LilyPond?
I'm not sure, but if the OCR works with MusicXML, then you can use the
`musicxml2ly` command to convert the XML file to a LilyPond file.
## What shell are you using with the fancy autocomplete?
-
Zsh with fzf.
## Do you use any kind of Emacs to MIDI interface besides exporting MIDI from LilyPond?
-
No.

## My current workflow for tagging music is to first apply ReplayGain in foobar2000, fix egregious mistakes there (like funny directory structure, lack of album artist, &#x2026;), then use beets to apply metadata from Musicbrainz/Discogs and go over the remaining albums with foobar2000 again. I wondered whether there's a chance textual tagging could allow doing it all in one program, have you experimented with mass tag updates/queries?

# Questions

## Can minor-modes in Emacs be integrated via chimera as a "mode"?
-
-- Good question. More likely, minor modes could be coupled to rigpa "modes", towers (sets of modes), or complexes (sets of towers), so that entering those modes/towers would enable those minor modes, and likewise disable the minor modes upon exiting. E.g. for Lisp editing, we might want to enable the symex / paredit minor mode in Lisp tower, and disable it upon swapping to Vim/Emacs tower.
+Good question. If it is already a "modal"-like minor mode, then we
+could potentially do it this way. But in general, it could make sense
+to couple minor modes to rigpa "modes", towers (sets of modes), or
+complexes (sets of towers), so that entering those modes/towers would
+enable those minor modes, and likewise disable the minor modes upon
+exiting. E.g. for Lisp editing, we might want to enable the symex /
+paredit minor mode in Lisp tower, and disable it upon swapping to
+Vim / Emacs tower.
## Do you think it would be hard for people to remember all the modes and bindings?
-- Bindings, no - it would be easier than currently because the bindings generally stay the same across modes (e.g. hjkl always means left down up right, and there are other conventions)
-- Modes, if the tower is 2-3 tall, then it's not a problem at all. Totally intuitive. For > 3 it might be hard, so I think in practice you would alternate across more small towers rather than have fewer big towers
-- Also, most modes are always available via "direct access" keybinding (eg. s-w = window mode), so you can jump to one at any time, and it'll return you to your original position in the tower when you exit. Modes don't need to be in the current tower in order for you to use them. But if you're using them frequently you might want to add them or temporarily switch to a tower that has them &#x2013; whatever feels the most natural for the specific case.

## Which retro theme are you using?
-- green phosphor
+green phosphor.
## Will this involve defining more epistemic-modes for non-editable buffers like Dired? How do you deal with the explosion of the number of modes?
- This is a great question, so here is a long answer:
- - I am keen to keep this extension lightweight so that it plays well with existing Emacs tools without needing a custom ecosystem. The modal interface abstraction layer "chimera" would be a big part of this, enabling existing modal-like interfaces to be recognized in the framework out of the box, meaning that they would be automatically "wired into" the broader framework via the standard exits (e.g. Escape and Enter)
- - I'm not sure what the best way to handle dired would be, but if it could be handled in this way, then that would be the way to do it.
- - The "complex" of towers initially available is tied to major mode, that takes away some of the complexity right off the bat. E.g. when you open a Lisp file it gives you a Lisp-related + general-purpose complex of towers
- - The idea is to support the "explosion" of modes, but make it scale well by (1) having them be structured, and (2) the structure being the same at every level

## How do you deal with the mental overhead of keeping a stack of modes and your position in it? While this simplifies the actual editing process by defining them as a single set of keybindings, the complexity is transferred to navigating modes.
-- While the complexity is transferred, the nature of that complexity is different. In the case of keybindings, the complexity is unstructured and ad hoc, whereas in the case of mode navigation, it's a matter of "going to the right place" for your keys to have the right meaning
-- In practice you would only have towers of size 2-3 I would guess, with every other mode jump always being available via an ad hoc jump (e.g. even in Vim tower, you can always jump to Window mode and it would return you to the original mode you were in upon exit)
-- And the main paradigm would be swapping between small towers
