Reaper is a DAW like RB, but with a deeper feature set. It just does not do any RTs type stuff, it is really more like Sonar than Rb.

I use a lot of Plugins in RB. in any audio track just open the track up by clicking on the down arrow, and add FX with the Edit Dx box drop down. Or in the mixer view the FX button in the tracks.

A box will open put any Effect in any of the 4 slots.

To add synths in RB, just click the DXi button at the top tool bar, and add any available, or there is an option to add a VSTi to the list. Click that and browse and find any folder with .dll files for synths and click them.
