Yes that keyboard will be fine.

Just teach yourself the major and the minor chord for each note and you will get it.

Although you have 49 keys on the keyboard you only have 12 notes in an octave. So you only need to learn the Major and minor chords for 12 notes.

Look it up on the net. All you need to do is work out which key on the keyboard is which note.

Then play around until you find one note on the keyboard that seems to blend in with a song and see if the best chord is major or minor.
Mostly minor with trance.

Cheers
Nem
