SAM-SPL 64 Plugin

This VST2, VST3 and AudioUnit plugin lets you easily split a sample in up to 64 slices.

  • Use the pads in the plugin or a MIDI keyboard (slices automatically mapped to notes)
  • 2 play modes: hold or trigger
  • Play a single slice at a time or multiple (polyphonic)
  • Each slice can be set to loop and/or play in reverse
  • Edit the sample (Trim, Cut, Crop, Normalize (0dB, -3dB, -6dB), Resample)
  • Continuous smooth zoom all the way to the sample level
  • Show zero crossing
  • Load a sample from the file system or directly sample an input (built-in sampler)
  • Drag and drop a sample in the waveform view
  • Export the sample as a file (wav / aiff supported)

Check the SAM-SPL 64 documentation for further details.

  • Scrollbar overview now displays the stereo sample

2020-08-03 - v1.4.1

  • Improved performance when loading a large file (especially on Windows 10)
  • Display a warning dialog if loading a large file to allow to continue or cancel

2020-04-27 - v1.4.0

  • Added slices display in the main waveform (Play tab)
  • Improved performances (less disk access)
  • Fixed several issues when file sample rate doesn't match DAW sample rate
  • Some minor UI tweaks

2020-03-30 - v1.3.0

  • The number of slices can now vary smoothly between 1 and 64 thus allowing higher precision
    • A new LCD window displays the number of slices (and as a shortcut, you can click and drag on the window to change the value)
    • Up and down arrows let you change the number of slices in whole numbers
    • A knob on the edit tab lets you freely change the number of slices
    • Shortcuts for 1/16/32/48/64 slices can be used
    • Thanks to Denis Safiullin for suggesting the feature (based on the behavior of the Akai MPC 1000)

2020-03-18 - v1.2.0

  • Added Settings tab
  • Moved Root Key to Settings tab
  • Added Cross Fade setting (on by default) to avoid pops and clicks
  • Added Routing setting to handle mono file (mono -> mono or mono -> stereo)

Note that Cross Fade and Stereo Routing are on by default because this is what makes the most sense for the vast majority of use cases. As a result, projects using this device may sound slightly different after this update. Disabling cross fade and/or stereo routing will revert to the behavior prior to this update.

2020-02-09 - v1.1.0

  • Added "follow" option so that the selected slice follows MIDI input (ex: via MIDI keyboard)
  • Added "Quick Edit Mode" to be able to quickly and conveniently see/configure the settings of each slice (loop/reverse)
  • Added "Loop" action to loop on/off all slices at once (note that if not all slices are looped, then hitting "Loop" will make them all loop)
  • Added "Reset" action to resets the settings (loop/reverse) of all slices at once

2019-09-19 - v1.0.0

  • first public release / free / open source

Configuration and requirements

Check the Jamba requirements for instructions on how to install and configure the VST3 SDK.

Build this project

The following steps describes how to build the plugin:

  1. Invoke the python script to configure the project
  2. Run the (resp. jamba.bat) command line to build, test validate...


  • For simplicity I am creating the build at the root of the source tree, but can obviously be outside the source tree entirely by running the script from anywhere

      > ./ -h # to see the help
      > ./
      > cd build
      > ./ -h
