How to use Midi Sequencer Mega Baby as a blind user

[germanocarella]

Hi to all,
I need some help on correctly setup megababy sequencer as a blind user.
I found only videos on internet, but I'm unable to understand how I have to do.
I need help to setup megababy, create new patterns and use these patterns.
I tried to create a midi track with an instrument. I added megababy to this track.
With my screen reader I'm able to scroll the sliders, but the "triggers" window is completely not accessible.
Megababy is written in JesuSonic language. I know python, but not JesuSonic, so, I don't know if it is possible to make the "triggers" window more accessible for screen reading software.
So, I'm wondering if it is an other way to create and use patterns.
I found some videos, but I can't understand them…
Help!

Mega Baby primary interface is drawn with graphic primitives. Screen readers are not working with that.

If someone knows any "normal" step sequences, like it was(is) in Cakewalk, that can be helpful.
