The wave designer on the unit allows you to adjust the Attack and Sustain envelope parameters of your voices. This feature does not work automatically. As it is part of the FX Bus on the unit, you must assign each voice using the SEND setting. To do this, follow the steps below:

1. Press SEND in the FX section.
2. Use SELECT to assign which voices go to the bus (solid red LED is bus send on).
3. Press SEND in the FX section to return to playback.

Once assigned to the bus, your Attack and Sustain dials will affect the sound. With both Attack and Sustain dials at the central position, the wave designer is having no effect on your transients. 

We would not recommend using Sustain on voices with a naturally shorter envelope, such as rim shot, as this may cause excessive noise.
