Need help recreating synth sounds in Logic

I came up with this riff in GarageBand on my iPad and I want to build a track around it now in Logic - I'm terrible at creating sounds though, i usually just find sounds i like by accident. Can anyone give any pointers on how to recreate the two instruments using Logic synths? Cheers.

what did you use to create the riff in garageband?

The first one that comes in is called 'car horn bass' and the second's called 'neon koto' - doesn't tell you what synth it's modelled on or anything on the iPad app. You can't export midi either, and it's also that I can't figure out if they use fifths or the octaves doubled etc that's giving me a headache.

Can you post it again? URL is dead.

But the way I deconstruct synth patches is by starting with the waveform and going from there.

I set it to private so it wouldn't show up on my Soundcloud profile so I think that's why it hasn't embedded - if you click the link below the embed it should work.
