Spat4Sends uses the first four sends of live to easily spatialize the sound.
Just drag the device on a track, move the knob and the sends will be controlled.
A slide time can be used to smooth the output. Two sliders also control the position and can be mapped for further control (with the Max4Live LFO for example).
