Difficult task, even tho' it appears much easier on first sight for lap steel than for pedal steel.

If PGMusic has a software module to convert notes into numbers then I see a possibility. I see that possibility with a large "BUT". There is always the difficulty of the playability of such a tablature.

While on a pedal steel you almost never (!) slant the steel bar it is common for lap steel players. Without slanting the steel bar, all notes of a single instance -- single note or notes with harmony and chords -- are played on the same fret, (with a pedal steel you also have to have an information which pedal...) still it is all on the same fret.

To give the relevant slanting information it is also important where on the fretboard you will slant the bar. The same harmony might not be achievable at some of all the possible areas on your fret. Another complication is the tuning. What is possible with one tuning might not be possible with another. That exactly is the difficult task.

Back then, when I played pedal steel, I used regular notation, but enjoyed a tab every now and then for some crowded areas on the staff.
