FXP files are the program files generated by the MonoFury VST by Full Bucket Music. To access these files:
1. Download and install MonoFury VST by Full Bucket Music in your DAW; it's FREE!
2. Copy the FXP files to your disk.
3. In the MonoFury VST, go to 'Options', select 'Load Program', choose an FXP file.
4. Presto! You have a digital file of the MonoPoly patch.
What the FXP files don't show are the mod-wheel positions, which are often critical to the sound. I generally start with the mod-wheel about midpoint, then go up to dial in the sound.
My Patreon page has .wav files of each patch. The patches were recorded with just a touch of reverb; no other effects.
