Looking for an instrument on reason

[Luca]

Hello guys, i'm sorry in advance for my english, i'm from France.

I have a few requests.
I had for a while an app on my iphone called "Figure" (Allihoopa), i made a lot of song on this app (i know, this app is like a toy).
It seems to be impossible to transfer your song that i made, on reason (yes you can, but only in Audio).
So i started to try to make the same songs i made on the app, on reason.

But there is some instruments (one called "Leader" in the Bass especially) that i don't found on Reason.
And i'm a little too lost for now for try to make the instrument from the beginning.

Do you have suggestions for me? Or some tutorial for making sound?

This is the link of the instrument in question : https://allihoopa.com/s/8OFm44Kq

Thanks a lot for helping an ignorant in english talk
