Earthquaker Devices Spatial Delivery® Envelope Filter with Sample & Hold

1. Range: Adjusts the sensitivity of the envelope in Up and Down mode. In Sample and Hold mode, this controls the speed.

2. Mode Toggle: This toggles between Upward Sweep, Downward Sweep or Sample and Hold.

3. Resonance: This is the filter feedback control, it adds more body and ring to the filter voice.

4. Filter: This crossfades between high pass and low pass filters and allows you to get everything in between. High pass is fully counterclockwise, low pass is full clockwise and center is band pass. This is much more useful than a simple switch because it allows you to blend the filters for different sounds!
