Making two different patches sound correct

[///AznTi]

Ok so the problem I'm dealing with now is having two different sounds that I am playing in KEY but the two different sounds do not sound well together. I like them in their own aspect in terms of timbre and the quality that comes out but when they are mixed together for example when one patch is playing and calls the other patch...it doesnt sound right.

The tone just sounds off. I know I'm playing them both in key but it just erks me that its not the way I want it.

How do you get the two different patches to sound more in tune with each other?

Detune?
Fine tune?
Pitch?

Yeah I know I'm a newb but I'm working at becoming better.

Here is a song where you can listen to all the different sounds but the overall tone and pitch are right plus everything is tight...hehe

EXAMPLE

Eventhough the keys are simple in this song....one patch is playing with the filter modulating and will wait for the other sound to come in and they take their turn allowing each other to breathe while the bassline is rolling and the percussion makes some changes.

This all make sense? Well I'm just trying my best to make the sounds I have created all make sense and sound in tune with each other.

Thanks for reading.
