Spacial Delivery is a voltage-controlled envelope filter that doesnt end up with just an auto-wow like a funk music. It also has a sample and hold function that is commonly found in vintage synthesizers. Spacial delivery has three functions to choose from: upsweep, downward sweep, samples & hold. Up and down modes will give you a sensitive filter experience that is sensitive to the input signal. You can also use Range, Resonance, and Filter with gentle phase-like sounds, and set the peaks of the filter to a very high range and use it wild! Adjust the desired input sensitivity with Range and adjust the filter feedback with Resonance. Turn the knob to the left for a round and muted tone and turn to the left for an edgy tone of tone than treble. The Filter acts as a low pass filter and high pass filter, and the knob adjusts to cross fade. In sample & hold mode, the voltage applied to the filter is irregularly changed internally, so the sound of the filter will be irregular. When using this mode, the speed of the filter change can be adjusted by Range. In order to ensure the tracking of the input signal, we recommend that the spacial delivery is the first stage of the other use effector, but you can also bring it to the back of the other effectors you are using to make use of the poor sensitivity of the input signal to create interesting effects!
