File Manager

Browse, upload and download files on your EP device

Overview

The File Manager does what the official browser tool does but faster and with batch operations. Browse your device's sample slots, upload new samples, download existing ones.

The app caches samples in the background as you browse. This means backups are nearly instant once the cache is populated. Works offline too since it's a desktop app, not a browser tab.

Browsing Device Files

The File Manager displays all samples in a sortable table:

  • Slot: Sample slot number (1-120 on EP-40)
  • Sample Name: The filename of the sample
  • Channels: Mono or Stereo
  • Bit Depth: Audio bit depth (usually 16-bit)
  • Sample Rate: Audio sample rate (usually 44.1 kHz)
  • Duration: Length of the sample in seconds
  • Size: File size in KB or MB

Click any column header to sort by that property. Use the category tabs at the top to filter by sample type.

Uploading Samples to Device

Adding new samples to your device:

  1. Navigate to the target category - Click the tab for the category you want (KICK, SNARE, etc.)
  2. Find an empty slot - Look for slots marked as empty or containing samples you want to replace
  3. Click "Upload" on that slot - An upload button appears for each slot
  4. Select your audio file - Choose a WAV, MP3, FLAC, AIFF or other supported format
  5. Wait for transfer - The file will be uploaded via USB MIDI (this may take a moment for larger files)
  6. Verify the upload - The table will update to show the new sample details

File Format Conversion

EP-PatchStudio automatically converts uploaded files to the EP device's required format (16-bit, 44.1 kHz WAV). You can upload any supported audio format and it will be converted on-the-fly.

Downloading Samples from Device

Backing up samples from your device:

  1. Navigate to the category - Select the category containing the sample you want
  2. Click "Download" on the slot - A download button appears for each filled slot
  3. Choose save location - Select where to save the file on your computer
  4. Wait for download - The sample will be transferred via USB MIDI

You can also download multiple samples by selecting them and using the batch download feature.

Deleting Samples

Removing samples to free up space:

  1. Locate the sample - Find the slot you want to clear
  2. Click "Delete" - Confirm the deletion when prompted
  3. Slot cleared - The slot is now empty and available for new samples

Warning: Deletion is Permanent

Deleting a sample from your device cannot be undone unless you have a backup. Always download important samples before deleting them.

Sync Status

The File Manager shows a "SYNCING" indicator when communicating with your device:

  • Initial sync: When you first connect or navigate to File Manager, all samples are loaded from the device
  • Upload sync: When uploading, the file is transferred and verified
  • Download sync: When downloading, the file is read from device memory
  • Delete sync: When deleting, the slot is cleared and updated

Wait for syncing to complete before disconnecting your device or navigating away from File Manager.

Tips & Best Practices

  • Organise by category: Use the category tabs to keep your samples organised
  • Download before deleting: Always back up samples you might want later
  • Check storage indicator: The top bar shows total samples and storage percentage
  • Use descriptive names: Rename files on your computer before uploading for easier identification
  • Monitor transfer times: Larger files take longer via USB MIDI, be patient
  • Keep device connected: Don't disconnect during file operations
  • Create backups: Use the Backup & Restore feature for full device backups

Troubleshooting

  • Check USB connection is stable
  • Try a smaller file size
