I would like to see Serato Sample expand its stem separation capabilities beyond the current 4-stem model (Vocals, Drums, Bass, Other) to include additional instrument-specific categories:

Backup Vocals - separated from lead vocals
Drums - broken down into sub-categories:
- Kick
- Snare
- Cymbals
- Percussion


Guitar
Keyboard/Synth

These could be implemented as optional advanced stem categories that users can enable when they need more granular control

Why This Feature Would Be Useful:
Current 4-stem separation is excellent for basic mixing, but many creative DJ techniques and genre-specific mixing styles require more precise control over individual instruments. For example:

Reggae/Dub Production: Isolating percussion elements separately from kicks and snares is essential for authentic dub mixing techniques and creating space in the mix
Live Remixing: Being able to isolate guitar or keyboard parts allows for more creative acapella blends and mashups
Backup Vocal Manipulation: Separating backup vocals from lead allows for call-and-response effects and more dynamic vocal arrangements
Detailed Drum Control: Individual control over kick, snare, cymbals, and percussion enables more sophisticated drum editing and rhythmic creativity

This would give DJs significantly more creative freedom while maintaining workflow efficiency.

Thank you for you consideration.
