Three-note tremolo in 4/4

[Dijkhuizen, J.F. van]

Hello everyone,

I'm trying to fit a three-note tremolo into a 4/4 measure.  I've sort of been able to do this as follows:

\version "2.22.0"

\relative c''

{

\repeat tremolo 8 {\tuplet 3/4 { g32 d c }} 

}

(Of course you could hide the tuplet numbers here.)

or:

\version "2.22.0"

\relative c''

\new Staff = "Example" { 

\time 4/4

\set Staff.timeSignatureFraction = 3/4

\scaleDurations 4/3 { \repeat tremolo 8 { g32 d c } }

While both look more or less OK, the notes appear as dotted half notes, rather than as whole notes. They should be whole notes, since the tremolo lasts the entire measure but I can't figure out how to do this.

Does anybody know of a way to create a 3-note tremolo in 4/4 time in which all three notes appear as whole notes? A bit like the MuseScore mock-up below:

Thanks for your help!
