The OP-1 has several hidden synth engines and Easter eggs:

Hidden synth engines:

COW (Choplifter):

  • A classic arcade game hidden in the OP-1
  • Press shift multiple times in certain modes
  • Or access through specific key combinations
  • It's a game, not actually a synth!

Easter egg sounds:

  • Some engines have hidden modes
  • Try holding shift + multiple buttons
  • Or try specific key combinations while in different modes

How to access hidden features: 1. Many are firmware-version dependent 2. Some require specific button holds during boot 3. Check OP-1 forums for current discoveries 4. Teenage Engineering occasionally adds new ones with updates

Known Easter eggs:

  • Choplifter game (varies by firmware)
  • Hidden LFO modes
  • Secret color schemes
  • Special sounds in certain engines

Finding Easter eggs:

  • The OP-1 community actively documents these
  • Official Teenage Engineering guides hint at some
  • Reddit r/OP1users has threads dedicated to discoveries
  • Some are deliberately obscure

Note: Easter eggs and hidden features may change with firmware updates. If you're on an older firmware version, some features may or may not be available.

Disclaimer: The exact methods to access hidden features can vary. If something doesn't work, it may be firmware-dependent or require specific conditions.
