Getting started

From the project's README ("Download and install"):

  • VAPORA 1.2.4 plugin
  • 15 factory presets — for new installations
  • Stone Hall preset update — replace only Stone Hall in an existing bank
  • Checksums

Requires the original OP-1 with Hundekraft 3.0.2. This is not an OP-1 field plugin.

Open the Hundekraft Workshop, add vapora.knl under Your plugins, connect the instrument, and use Update OP-1. Follow the Workshop’s transfer/restart instructions.

For a new installation, unzip the preset pack and copy its synth/vapora folder into the instrument’s synth folder in normal disk mode. Eject and allow synchronization to finish. If upgrading from 1.2.3, update only the plugin; keep all presets. If upgrading an older installation that lacks the Stone Hall update, update the plugin and replace only synth/vapora/stone hall.aif from the Stone Hall update. Keep the other fourteen presets. Eject, allow synchronization to finish, then reload Stone Hall. Keep a copy first if you edited your existing Stone Hall.

Deep Pressure uses the separate Hundekraft reverb effect; Stone Hall uses plate. Install those effects to use their saved settings. The OP-1 supplies the T2 envelope and optional T3 effect.
