Neither the SDE-3000EVH nor the SDE-3000D has a dedicated editor application. Edit all parameters using the buttons and knobs on the top panel of the unit.
If you want to control the unit from a computer, the USB port (USB Type-C®) supports USB-MIDI. You can use MIDI control change and program change messages to remotely control parameters and switch memories. For the full list of supported messages and addresses, see the MIDI Implementation document.
