64 Note Piano Roll vs 88 note keyboard

What can I do to access and edit the notes that extend beyond the 64 note range of the JJOS (free) piano roll?

Use step edit

or

transpose the notes and the sound

Make your track a MIDI track type instead of a DRUM track type, and then enter your notes with an external keyboard.

DRUM tracks are limited to the 64 notes covered by the pads, but MIDI tracks have access to the full range.

^^ That´s another solution

is it possible to assign note values > 100 e.g. e7,F7 to the pads?

thx
