As a huge fan of the Play series, I’ve built a free browser-based tool designed to make creating sample packs for the Polyend Play/Play+. It makes pack creation easy, fast, and visual.

I hope you enjoy using it and welcome your thoughts.

KW’s Sample Pack Creator: http://spcreator.app

:sparkles: KEY FEATURES:
• Completely free (support through donation if you love it)
• Drag & drop files or entire folders (WAV, MP3, AIFF)
• Vintage Sampler effect option with authentic hardware character
• Auto-naming all samples by category (e.g., kick_1, kick_2) with one click
• Auto-leveling switch for consistent volume
• Auto-trim silence switch for optimized memory
• Waveform editor with cropping & slicing
• Direct USB export to Play Plus!
• Automatic 16-bit/44.1kHz conversion
• Save projects for later editing
• Supports up to 255 samples
• Works offline - everything runs locally (your samples stay yours)

:light_bulb: WHY USE THIS TOOL:
No more manual sample preparation! This free tool handles all the tedious work - format conversion, organization, naming, volume matching, and even adds vintage sampler character. Export directly to your device or create reusable project files.

:locked: PRIVACY FIRST:
All processing happens in your browser. Your samples never leave your computer. No accounts, no signups, no uploads, no tracking.

Have fun,

KW

Rad! I imagine this will come in very handy for me and my workflow. I’ll be trying it out very soon. Will def support if it helps me as much as I imagine it is going to. Thanks!

I really appreciate that! My personal performance style is very spontaneous and improvisational, so I wanted a tool that was able to meet that demand.I do hope you have a ton of fun with it.

Ps, be sure to try the chop tool on some of your loops; It instantly creates individual samples out of your slices which I find to be very satisfying.

I’ve taken the liberty to move your post into the Scene > Tools category - hope that’s ok.

Yes that should speed up things significantly as a big part of my process lately involves resampling and slicing my pattern stems from Tracker on the Play which I am currently doing fairly manually.

:information: small gotcha in case anyone else runs into it:

  • Audio processing seems to work great in Chromium based browsers (Chrome, Edge, Brave, Vivaldi etc).
  • But if you got a strong privacy/ad blocker running (uBlock, Brave Shield etc), you might have to disable it or processing gets stuck.

Just a heads up. Great work @kmwarner! :partying_face:

Let me know how it goes!

Good heads up, where does the processing get stuck for you? And specific blocker are you using?

13
  • I‘m on Brave and it was the default brave shield.
  • Starts blocking right after you try to preview a sample with the vintage processing enabled.
  • Haven‘t looked at the devtools yet, to give you a more precise indicator where it might error out.

Let me know if you want me to have a look and let you know if anything meaningful comes up in the console. :hugs:

14

Yes, if you can copy your console data, share it here or dm me if there is a way to do that here.

Alright just ran it one more time with the Shield enabled:

after clicking on sample preview
after clicking on sample preview1510×2160 491 KB

eventually it throws the following message
eventually it throws the following message1275×580 115 KB

  • So once i click preview, my GPU starts ramping up, which is interesting as well.
  • Having a look at the browser processes, shows it spinning up to 100% cpu
  • I’ve let it sit until i guess either a timeout occurs or chromium decided to kill something
  • Which then returns the error message you see in the second screenshot

So essentially not much of an error that tells us anything.

Ah, I was able to replicate it. Made some updates now in v1.0.2 (see bottom right of app to confirm your version) that make it a bit more graceful about timing out in more defensive environments but added a heads-up to visitors via the first time welcome screen so they know to temporarily disable if it’s an issue. Thank you, Sandro!

This is awesome! Thank you for making this. I made a feature request for something similar a few months back, but never thought it’d be granted like this lol very cool stuff!

Thank you so much for sharing this. This kind of tool, which is (somewhat) similar to the Move Manager (Ableton Move), is truly extraordinary. It greatly simplifies tedious and largely irrelevant tasks related to music creation.
