Single bass notes in chordmode

[Henning Hraban Ramm]

Hi,
this was already asked in 2012 (by me) and 2015 (by someone else), but there 
was no answer. I hope it’ll work this time ;)

In some of my songbooks, the chord line (for guitar) is interrupted by single 
bass notes, i.e. you are supposed to play only these strings.

The notation is mostly a smallcaps letter with a bar above (or a small x 
below), but a simple /G would be enough if it isn’t possible otherwise.

And I’d like to have that bass note also in MIDI output.

Is this possible, and how?


Preferred syntax: r/g or s/g
Because a rest with a bass is only bass.

E.g.
\chordmode {
  a2:m r4/g r/f |
  g2 a:m |
  a:m r4/f r/g |
  g2 f |
  d:m f |
  g r4/g r8/c r/b |
  a2:m a:m |
}


Best regards,
Hraban
