now alphatab look like this pic

but it view on guitarpro 8 like this pic

The spacing algorithm is a rather fixed algorithm with currently only 1 parameter: stretchForce

As described in this page we are using a variant of the Gourlay algorithm.

Looking at the given example generally most music notation software would layout like alphaTab, but Guitar Pro seems to switch into a special spacing mode when having multi-track display active.

Guitar Pro 8

alphaTab

MuseScore

SoundSlice

Flat.io

Guitar Pro 8 - Multi Track

alphaTab - Multi Track

MuseScore - Multi Track

SoundSlice - Multi Track

Flat.io - Multi Track

A little pity
Because I want to add the Numbered musical notation module
but it need more spacing on the half beat and whole

I'll think of another way

What exactly do you mean by "Numbered musical notation module"? If you share some insight, I might give hints on how to achieve it. e.g. if you need the positions of each note to put annotations you can enable includeNoteBounds and the BoundsLookup would allow you to get the position of all notes.

I thought once of a feature like MuseScore to have numbers/names in the note heads: https://musescore.org/en/handbook/3/notehead-schemes There would be various symbols for that.

If it goes more towards the Chinese numbered music notation, the starting point would be to make an own BarRenderer which is registered in the staveProfiles of alphaTab. The TabBarRenderer would be a good starting point to create a new renderer which has only a single line and displays certain note values as numbers.

Technically it would be possible to make also extensions to the spacing algorithms. e.g. to choose that the spacing is just equal on all notes ignoring timing aspects, or having a fixed logarithmic sizing ignoring optimizations like in the Gourlay.

very thanks for boss answer

Indeed, It's Chinese numbered music notation, I created a new BarRenderer myself，its copy TabBarRenderer

in the Chinese numbered music notation

Whole beat need four Quarter beat spacing , Half beat need two Quarter beat spacing

if Half beat + beat.dots need three Quarter beat spacing

You might want to keep an eye on #1505 for official Chinese numbered music support.
