I suspect with this being a 'portable' keyboard and those cables getting plugged in and unplugged frequently, pins are going to get bent

There is some foam inside to protect the keyboard during transit, and a small box inside that holds a couple AA batteries and the two MIDI cables (one USB type-A and one Lightning).

The other free software includes AmpliTube Custom Shop, Miroslav Philharmonik 2 Classik Edition, SampleTank 3 (highly recommended as it comes with lots of nice instrument sounds and great for playing), Syntronik, T-RackS
