I just updated the Ample Tele to 3.7.0 to try it out.
That's why I did it in RapidComposer as it gave more control than Riffer.
I can just drop the phrases from Riffer or Guitar Pro Tab Player into RC,
convert to relative form with keyswitches and it will fit over any scale or chord.
You can add controllers to the phrases and save them.
In the Edit Phrases mode you can add pitch bend controller at the bottom and draw to bend or copy the controller from the main track and paste.

I was using Ample ages ago and they were very slow to fix things like more bars import.
I showed them how to make it with a chord track years before EZBass, but the were too slow.
