WARBL Forum

Does anyone know if it is possible to reduce the amount of air/breath required when playing the WARBl and if so what setting do i need to change?

You can experiment with the "threshold" and "multiplier" settings in the "Advanced" panel. Lowering those will make it easier to reach the second register, thereby requiring less pressure overall to play. If you're talking more about the actual volume of air passing through the mouthpiece, there's not a setting that will affect that but you could experiment with partially plugging the exit hole. At some point I'd like to make a small rubber plug available for that purpose. You can even close off the exit hole entirely if you'd like to play without requiring any airflow at all.

Thank you for your reply. I will experiment as you suggest.
