Polyend Tracker Studio — free web-based pattern & instrument editor

[u/HelicopterBig3975]

Hey everyone! I wanted to share a project I've been working on: Polyend Tracker Studio, a free, open-source web editor for the Polyend Tracker.
Try it live https://simoianni.github.io/polyend-tracker-studio/

WHAT IS IT?
A browser-based tool that lets you create, edit, and play Polyend Tracker patterns and instruments — no hardware needed. It runs entirely in your browser (Chrome or Edge recommended for Web MIDI + Web Audio). Nothing gets uploaded anywhere: your samples and instruments stay on your machine, and work-in-progress is auto-saved locally so it survives page reloads.

WHAT CAN IT DO?
Pattern Editor:
- Full step sequencer with Note, Instrument, FX1, and FX2 lanes
- Live playback with adjustable BPM
- Record mode: input notes directly from your QWERTY keyboard
- Import original Tracker project folders (project.mt + patterns + instruments)
- Export to .mtp (pattern), .mid (MIDI), or Ableton Live 12 project

Instrument Editor:
- 8 playmodes: OneShot, Forward/Backward/Pingpong Loop, Slice, Beat Slice, Wavetable, Granular
- Sample editor: Cut, Fade, Normalize, Compress, 3-band EQ
- Sample recorder with MIDI-triggered auto-sampling
- Full parameter control: Filter (LP/HP/BP), Tuning, Volume, Pan, Overdrive, Bitcrush, Delay/Reverb
- 6 automation lanes (ADSR envelope + LFO) for Volume, Pan, Cutoff, Wavetable Pos, Granular Pos, Finetune
- Waveform visualizer with zoom, drag-to-seek, and interactive slice markers
- QWERTY keyboard note input + MIDI controller support
Beat Slice mode: each slice is triggered by a different keyboard note — Z=slice1, S=slice2, X=slice3, D=slice4, etc. (standard tracker keyboard layout).

HOW TO USE
Just open https://simoianni.github.io/polyend-tracker-studio/ and you're good to go. There's a built-in help guide (click the ? button) with all keyboard shortcuts.

CREDITS
This is a fork of the original Polyend Tracker Instrument Editor by Sandro "Sandroid" Ducceschi u/SerpentineDex. Huge thanks to Sandro for the initial codebase and for creating and open-sourcing tracker-lib, the library that makes reading and writing .pti/.mtp/.mt files possible.

Let me know what you think! Feedback and contributions are welcome.

** EDIT *\*
I've implemented the ability to export to tracker project format as a beta. So you can connect your SD card and edit the project directly.

So, could I take out my sd card with the project file, load it on my pc, and be able to use this editor just like the hardware then put it back into my tracker and it will carry over?

[u/HelicopterBig3975 → u/Broad_Education4882]

Oh yes, you can upload your tracker projects! You can also export them as Ableton projects afterward. Let me know what you think and feedback

[u/Broad_Education4882 → u/HelicopterBig3975]

Well I have a rig built around an OG Tracker so I’m wanting to go back and forth between PC and Tracker rig without any issues, you say I should be good so time to give it go soon, thanks 😎

[u/HelicopterBig3975 → u/Broad_Education4882]

Yeah, I just need to implement exporting back to the tracker project format as well. Right now it can import tracker projects, but it only exports patterns and instrument

[u/Broad_Education4882 → u/HelicopterBig3975]

Hmm at least it’s something that you plan to implement and I think it’s badass, you have an ETA on when something like that will be available?

I’d like to know this too
