a bit too much high end on the piano i think
Maybe a liiittle bit, but honestly I think it's fine.
should the arp be louder?
The chords them selves are verre nice, but they hit wayy to hard. You can see it in the waveform. Try putting like 2-5% attack on that.
all baddation 2 channels but 1 hour of work already for the perfect chords and melody
