ROLAND W-30 CONFIGURATION
Connect the W-30 realtime filter to the EV-5 socket by a stereo jack.
The trick is to set the EV-5 to receive the control 2 (Breath Controller) and the Breath Controller to the Aftertouch (to do it press Config2/F4 in the performance mode) and save your preferences in the System disk (Save/F1): now, you can manage the cut-off in your sounds by the realtime filter.
In the patch parameters assign the aftertouch (AT assign) to the Cut-off (C-O) and set the Cut-off in the tones you want to filter.
