Help me get only GarageBand sounds from my speakers.

I have a Roland RD-700 SX keyboard and I'm using an iRig MIDI to connect to GarageBand on my iPad mini. Currently, the XLR outputs of my Roland keyboard are connected directly to studio monitors. The iRig Midi's IN and OUT are connected to the keyboards OUT and IN, respectively. The problem I've having is that I'm hearing only the Roland's build in sound through the speakers, not the GarageBand sounds, which is all I want to hear. Is it possible to connect things so I only hear the GarageBands sounds? Or do I need more equipment? I'm new at all this so please go slow in your explanations. Thanks.

Sound can't be transmitted through MIDI, only metadata about sound(s). You will need to detach the monitors from the Roland keyboard and attach them to the headphone jack of your iPad. You will most likely need different cables to do that.

so if I a USB cable connected from my keyboard to say, Logic or MainStage, how do I get the sound of that program to come out of my keyboard that is connected directly to the speakers? Or am I thinking about this wrongly?

In other words, should the USB cable channel the sounds from Main Stage back to my keyboard and out the speakers or do I need something else in between?

It needs to not come back through your keyboard. Basic route should be keyboard -> computer -> speakers.

To elaborate using the typical terms for this sort of thing:

You want to play an instrument that exists as software on your computer, aka a softsynth.

For this, you need a MIDI controller. Any keyboard with MIDI out can serve as one, if you also have a MIDI interface, in this case your iRig. Most modern controllers can also connect via USB, and may have other features like knobs you can assign to the different parameters of your softsynth.

Softsynths interpret MIDI input, outputting sound to your speakers via an audio interface, which can be as simple as the headphone jack on your computer. More robust audio interfaces connect to your computer via USB or firewire and may have have higher sound quality, more inputs and outputs, and lower latency (the time between when you press a note on the keyboard and when it plays out of your speakers, measured in milliseconds).
