Gforce Software has released the OrchesTron Expansion Pack, a sound library for the M-Tron Pro virtual instrument for Windows and Mac.

As the name suggests, it’s an add-on pack for M-Tron Pro users with sounds recorded from the ultra rare and ultra desirable Orchestron optical playback instrument.

The Orchestron is an optical playback instrument manufactured in the 1970s. It generated sounds based on the same technology as the Optigan but instead of having a rhythm and effects section, it simply focussed on providing a single sound spread across the keyboard.

OrchesTron Expansion Pack features

  • Only available via Download.
  • 12 New tape banks all looped.
  • 35 Notes per tape bank.
  • Extremely rare sounds.
  • Over 100 New MTP Patches.

The expansion is available to purchase for £19.99 GBP inc. VAT.
