What are the specifics of hammer-ons and pull-offs?

I know that the engine does it automatically -- it has done it in my songs. But I've been trying to tinker with it. I made a bunch of small 'songs' to try to test it, but I've had no luck. For some reason, I dont' get any of them at all. Whole notes or 64th, 60 tempo or 240, it doesn't seem to affect it. What am I doing wrong?

EDIT: Well I tried one more thing, it seems that the tempo of the song before I export the midi from Guitar Pro is what determines it. The whole concept still seems iffy.

Well.. that depends on how Guitar Pro generates its .mid files when it exports.
The concept isn't "iffy", it's the tools people have to resort to use when creating the note charts that are.
It wouldn't be as "iffy" if you were using a real MIDI editor..

When I said 'iffy' I meant iffy to me.

From my understanding, in standard 4/4 measure (4 beats per measure), the game enables ho/po for any notes after the first that's faster than an eighth note (2 notes per beat) and on a different fret. So if you have 2 notes in a beat, no ho/po. 3 different notes in a beat, first note is picked, 2nd and 3rd is a ho/po. Same frets, no ho/po, like real guitar.

Take a look at Beast and the Harlot for reference. Measure #28:1, 4 notes in that beat, no ho/po cuz it's the same note. Measure 65:1, 2 notes in that beat but different notes, no ho/po. Measure 87:1, 4 notes in that beat, ho/po.

If you want to be able to do ho/po at a slower pace, you can change the measure to 2/4. In this case, the duration of the measure is the same, but the game treats the measure as 2 beats per measure, effectively doubling the # of notes per beat compared to a 4/4 measure, which effectively doubles how close the notes have to be to enable ho/po while maintaining the same tempo.

Take a look at Red Lottery for reference. Measure 2:2 has 2 notes in a beat, no ho/po. Then look at measure 5. There are 4 notes in the first half of that measure, so by 4/4 convention there are 2 notes per beat. Since the developers switched that to 2/4 measure, there are now 4 notes per beat since there's only 2 beats in the measure. So even though audibly it's the same note spacing in 2:2 vs 5:1, it's picked in 2:2 and ho/po in 5:1.

Hope that helps.

Wow.. That was a very complicated explanation, rage2

It's actually pretty simple.. A note is displayed as a HO/PO if all of the below conditions are met:

1. It is not the first note in the song
2. Its start is less than 161 MIDI "ticks" from the start of the previous note
3. It is on a different fret than the previous note
4. It is not, nor is the previous note, a chord

A MIDI "tick" is the internal time unit used, and it is not dependent on tempo.
