hi i'm hoping someone can help me with this as it's a really annoying issue that will cause me to dump this otherwise working instrument as it totally disrupts my workflow (and daw). my px-150 turns itself off after only a few minutes of inactivity. it's variable, sometimes 1min, sometimes 5mins, normally around 2min after the last keypress. if i play constantly, this doesn't happen - i've tested for 30mins. i've tried disabling the auto-power-off feature (which is supposed to be a 4 hour inactive period), but that does nothing either. any and all help is greatly appreciated! thanks larry
