Something I was playing with ...........

Pretty decent track.

I would only turn down the volume of the synth only a little bit.

They are a bit to loud.

Or even better.

To use the compression into the mastering fx chain.

Put the compression there, but make sure you have dry/wet settings balanced.

That way you can hear the original and compresed signal.

With this, you can have a very good quality while retaining the vibe and the tone.

Nice melodies btw.
