How to get more Sequencer Instruments?

#1 Posted by Xelalex (52 posts) -

I've nearly completed the story mode, and I've only got one single sequencer instrument, the electronic piano you get for listening to the tutorial on instruments. I'm a keen musician, so I can't wait to get started when I have more instruments to play around with, can anyone tell me how to get the rest of the sequencer instruments? Are they all in the story mode? If so, what level/worlds?

 

Thanks in advance.
