Organist updated

Organist from MooCowMusic gets an update:

V1.1 - Added various interface tweaks

• You can change the graphical style of the organ from church to electric.
  
• Notes and chords can be held while scrolling the keyboard, allowing a more fluid style of playing. You can even hold down a chord, scroll to a higher octave, hold down some more keys, and then individually release the keys of the lower chord one by one.
  
• Scroll lock buttons have been added in Dual Keyboard mode to allow you to hide the navigation buttons to avoid accidentally pressing them while playing.
