Organists want to sit down, turn on the organ and play it.  They want to be able to quickly navigate to their settings, and they don't want to fight with the organ to make music.  Opus-Two recognizes this and offers one of the simplest, yet most efficient user interface in the entire industry.

Without navigating menus, the organist can change memory levels, activate and control a transposer, and use the built in performance sequencer.  With configured controls, piston sequencers (including insert and delete), pedal divide, melody couplers, piston ranges/scopes, and more can be accessed without navigating complex menus.

The Opus-Two system comes in two sizes, compared below:

C-IV Controller

PIC Architecture

  • Folders/Users Not Supported
  • 250 Memory Levels
  • 250 Tracks
  • MIDI In/Out/Thru
  • 4 Analog Inputs
  • 1 PipeBus Connection
  • 1 Display
  • Configure with PC

CVA/CVE Controller

ARM Architecture

  • 250 User Folders*
  • 40 Memory Levels Per Folder*
  • 40 Tracks Per Folder*
  • MIDI In/Out/Thru
  • 4 Analog Inputs
  • 1 PipeBus Connection (3 on CVA)
  • 2 Displays
  • Configure with PC or Terminal

*Please note that in the ARM architecture, the number of memory levels per folder is adjustable by the programmer during system setup by defining the number of folders  The system (presently) supports a maximum of 250 folders, which is 40 levels per folder (10,000/250) and 4 tracks per folder (1000/250).  If configured for 100 folders, that is 100 levels per folder and 10 tracks per folder.  It is possible to leave all 1,000 record-play tracks global and only folder-divide the memory levels.  This is a common church application.

Both architectures allow the follow features “out of the box” (no special programming or magic required):

  • Ability to handle many keyboards including second touch
  • Transposer (+/- 7 Semitones by default)
  • Lit Reversible Pushbottons can be controlled (no need for external cards)
  • Multiple Sforzandos
  • General Piston Sequencer
  • Virtually unlimited number of stops can be controlled
  • Virtually unlimited number of indicator lights can be driven

Please remember that Opus-Two is fully customizable.  Many systems have been implemented with custom code to complete various functions – even custom display interfaces.  If a customer is not comfortable custom-created their own interfaces through code, we gladly will do this for them.  Simply reach out to us and tell us what you want!
