Piano on three staves?

[RST]

Here is a small question for the gurus of Opusmodus.

I am developing sketch materials for some piano music (a solo work and also a work for three pianos).

I am generating material as 'rh and 'lh using the piano-solo-layout.

What I am trying to figure out is how to make the layout three staves and to place the music by register into the three staves, so that the pianist can work out the fingering and hand-crossing more easily and effectively during the sketching and feedback process. 

Can anyone point me in a good direction?

 

With thanks!

This will be helpful to many!  Thanks Stephane!

 

What is still puzzling me is how to make the following transformation:

 

1) two streams of omn data (formatted length, pitch, velocity) as 'rh 'lh (perhaps merged into one stream using merge-voices) - and then transform to:

2) three streams of omn data for the three staves such that the data is parsed and separated as to register: high-middle-low.

 

What has me stumped at the moment is how to parse the data according to the pitch register after formatting as an omn stream while keeping intended length parameter intact.

 

I think I am getting close.  Your helpful comment re-invigorates my  problem-solving and I am grateful for that!

You can use the function ambitus-filter.

I will look into this.  Thank you for the tip!
