SampleBot

SampleBot is a Windows application designed to automate the process of sampling MIDI instruments. It sends MIDI notes to a hardware or software synth, records the audio response, and packages the results into WAV files and Akai MPC Keygroup programs (.xpm).

Features

• Automated MIDI Sampling: Automatically cycles through a user-defined range of MIDI notes.
• Velocity Selection: Supports sampling at three different velocity levels (Low, Mid, High).
• Audio Processing:
  • Automatic normalization to a target level.
  • Customizable start trimming to remove silence at the beginning of samples.
• MPC Keygroup Generation: Generates .xpm files for direct use in Akai MPC hardware or software.
• Real-time Monitoring: Monitor the audio input directly through the app.
• Customizable Timing: Adjust note and tail durations to capture the full character of your instrument.

Getting Started

Prerequisites

• .NET 10 or later.
• A MIDI output device (hardware interface or virtual MIDI cable).
• An audio input device (connected to your synth's output).

How to Use

1. Connectivity:
   • Select your MIDI Destination and MIDI Channel.
   • Choose your Audio Input device.
   • Enable Monitor Input if you want to hear the instrument through your computer speakers.
2. Note Range:
   • Set the Start and End notes.
   • Set the Step interval (e.g., sample every 6 notes).
   • Select which Velocities you want to capture.
3. Timing & FX:
   • Adjust Note Duration (how long the note is held).
   • Adjust Tail Duration (how long to record after the note is released).
   • Enable Normalize Audio to ensure consistent volume.
   • Set Trim Start (s) to remove any unwanted pre-note silence.
4. Output:
   • Provide a Filename Prefix (e.g., "MOOG_BASS").
   • Select an Output Folder where the WAV files will be saved.
   • (Optional) Enable Generate .xpm to create an MPC Keygroup program.
5. Start Sampling:
   • Click START SESSION to begin the automated process.
   • Use STOP at any time to cancel the session.
