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/](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 [Polyend Tracker Unified Editor](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. 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. **LINKS** Live app: [Polyend Tracker Unified Editor](https://simoianni.github.io/polyend-tracker-studio/) GitHub: [GitHub - simoianni/polyend-tracker-studio: Web-based pattern & instrument editor for the Polyend Tracker — import and export full projects (SD-card ready), edit patterns/instruments, MIDI & Ableton export.

Having something like this is a real dream of mine, I absolutely love this idea and have some requests to really kick this up a notch to be a useful tool for polyend tracker. namely a bunch of keyboard shortcuts: - Shift and arrow keys to **mark a selection** - Cut/Copy/Paste data in that selection - _then maybe Shift + U to un-select a selection?_ - Page Up/Down to **move up and down by 16 rows**. Home/End to jump to beginning or end of pattern. Also works with shift to select a region. - Ctrl + 1-8 to **adjust step jump values** (and a display showing what the current value is). - Keyboard should also ideally have two rows - one starting at Z like you have and another an octave up starting at Q. Very common in software trackers - Ideally some sort of pattern sequencer. - And this is a small nit pick but I’d remap **Note/Ins/FX1/FX2** to be 7/8/9/0 or something else so it maps the muscle memory of tracker on the right side. - Same with **play/stop** , maybe as enter or right Shift. - Right command or option as **play from currently selected row**
