turning off arps

For which synth?

To turn off the arp, just click on the button that says "arp" near the bottm left and chane the "pattern" to off

To start with a blank slate, click top right where it says "program"  and then initialize.

or you can just choose a patch that does not have an arp on it. if you look under headings like "keyboard", "lead" "short plucked", etc, you will find many non-arp patches
