v5 full stem split: stem bleed is worse than before

Bass is as wildly inconsistent as ever, and has the added complication of synth stems bleeding into it now.

Drums sound fantastic, no notes. Cymbals finally punch through will some rounded out sound. I will definitely be using the v5 drums with v4.5+ everything else.

Guitar stems seem almost non-existant *for me*. I make primarily instrumental ambient style metal, which is very guitar centric. The FX and Synth stems have nearly all the guitar parts ([this is the track I used](https://suno.com/s/Dwi6hsyX8J5OWMWx)) which could be fine but Suno does need to get better at identifying what "instrument" goes on what stem.

I know v5 is essentially in beta right now, I just wanted to warn / spread this to people who aren't saavy with mastering and fixing problems like this.

I'd give a toe for MIDI stems.
