Nice work! If you don’t mind, can I suggest a few things to work on..?

My first impression is that you are making a very common mistake of mixing the melody so that it sits ON TOP of the track, not ‘inside it’. Naturally we tend to want to emphasize what WE played and downplay what the machine did, but every part is equally important. Mix it like you had played EVERYTHING..!

If you listen to pro recordings, there’s no problem hearing everything. The backing doesn’t swamp the lead, and the lead doesn’t swamp the backing.

Next thing that’s worth working on is dynamics in the lead voice. If you don’t have an expression pedal, that’s far more important than another module! But if you can’t get one, you can always ‘draw’ in CC11 (Expression) slopes. Especially in the flutes, listen for how real players play louder and quieter to give the phrase some shape, and also on long notes tend to die away just a bit. Your flutes sound like they have never ending lungs!🫁 Try singing along with your wind parts as you play them, and you’ll quickly get an idea of when you’re running out of breath!

But strings also swell and die, and this can also help increase the realism.

Another thing that can help push a little more realism is to edit your drum fills so that no two are EVER the same. Drummers treat the fills as their little moment to shine, they’re fine with keeping the basic beat steady but always want a little individuality for the fills. And again, a little bit of rise and fall of either velocity or CC11 can help support the dynamics you put into the lead line.

Lastly, I often find that doubling the string section melody with just a solo violin or cello mixed WAY back can give the impression that the section has a ‘leader’ (which in real life they usually do!). And allow the leader to come forward in the mix a bit as the section swells.

Strings are a lot more complicated than what a single section sound can do, so it pays to add in the solo sounds (violin, viola, cellos and bassists) a little bit to give each part some character. I use an iPad and the amazing SWAM solo strings to get the articulations, but even the ROM solo strings in the BK9 can push the realism up a notch or three…

Keep up the good work. Nice to hear some Bach here for a change!
