For the ones who could be interested, I just published a delay effect for Bela pepper.
This delay is mono or Stereo, and provides a pingpong.
The delay can be sync with incoming trigger on analog input 7. ( tested with Temps Utile eurorack module) . In that case, do not forget to configure your Bela pepper jumpers for receiving triggers for that input.
LED bar shows if options are on/off and displays the delay
The patch is located there: https://patchstorage.com/pure-data-delay-effect/
Short description how to use in image below.
Hope this helps.
