Feature Request – External Track Envelope Follower for True Per-Track Sidechaining

Hey Polyend team,

After digging deep into the Tracker+ manual and exploring the architecture in detail, I’ve realized we currently don’t have true per-track sidechaining — likely due to performance limitations. That’s completely understandable, and I genuinely respect the choices you’ve made to keep things running smoothly.

That said, I’d love to propose a feature that could massively enhance the Tracker+ experience — especially for those of us producing hip-hop, lo-fi, and house:

Can we get an external track envelope follower that responds to audio output or note triggers from another track — allowing modulation of parameters like volume or filter?

Here’s a real-world use case:

  • I place a kick on Track 1 and sample chops on Track 2
  • I’d like to apply an envelope follower to the sample chops (Track 2) that’s triggered by either:
    • The audio output of Track 1, or
    • The note-on event of Track 1
  • Then I can modulate volume, filter cutoff, or other parameters with attack/release shaping — achieving true rhythmic bounce instead of ducking the entire master

Right now, the master limiter’s sidechain affects the whole mix — which sounds cool sometimes but isn’t always musically useful for this kind of groove-centric production.

An envelope modulator with track-to-track routing — even if only via note triggers — would bring real dynamic interaction between elements in a mix and allow for nuanced, expressive sound design.

Please consider this for a future firmware or Beta update. I truly believe a lot of us would use this daily.

Thanks again for pushing boundaries with Tracker+. You’ve built something special.

Much love,
B4Lasers
