GSi Free Vibes is a Physical Modeling emulation of a Vibraphone. It doesn't make any use of sampled material as the sound you hear is completely generated in real time thanks to some pretty complex math calculations performed by your device while you play.

Main Features:

• Physical Modeling - no samples
• Full polyphony (49 notes)
• Two different modes: Keyboard or Mallet
• Adjustable mallet hardness
• Available as stand-alone and AUv3 plugin
• Very low CPU and RAM usage

Buying the PRO Version (iOS only) gives access to additional parameters:

• Built-in Program manager with unlimited programs
• Authentic Tremolo effect that does not kill the attack transients
• Harmonic manipulation parameters to craft the sound in more detail
• Decay parameters for both the short and long notes
• Ambience and Microphone settings
• Mute Below Velocity function to mute notes if the note-on messages is below a given velocity level
• Extended integrated user manual

PLEASE NOTE: the IAP is completely optional, the instrument has no limitations.
