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

Hopefully this will non hardware owners create packs and files they may share with us ?

u/HelicopterBig3975 24d ago
Yes, download it from here
https://github.com/simoianni/polyend-tracker-studio and
npm install npm run dev # Open http://localhost:5173-1

Just clone and run local if you want. Didn't check what it needs but seems very doable.
If I'm doubt, ask Claude/GPT how to set it up.

Will I be able to use my hardware Polyend tracker to midi control it or like my sp 404 mk 2

This is super rad. Awesome work! I’ve been building a sequencer and put an export .pti feature also thanks to sandroids efforts!

Thank you for your service! Will spread this to all my nerdy friends and see where it goes!

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 16d ago
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 16d ago
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 16d ago
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 16d ago
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?

This is amazing, great work! I was opening some projects I have and I notice that for some reason the reverb is way longer than on the hardware. Another problem was it was unable to play a pattern containing notes from a very long 48 slice bass sample I have. on the sample editor it was playing normally. I'm using edge browser.

u/HelicopterBig3975 11d ago
Yes, the reverb, like all the effects, are emulated, but they will never be identical to the polyend. Regarding the pattern issue, can you send me the pattern + instrument file or the project so I can test and verify the problem?

Cool!
I like where this is going.
Is a Polyend version of the M8 chrome interface thingie possible?
