M50 started making strange sounds on certain patches (stock and custom). Effects are off. Any ideas? Thanks!!!!
The first is the straight-out-of-the-box "M50 Grand Piano". The noise will become apparent as the piano starts to decay.
Second file is a synth brassy tone. The noise sounds kinda phaser-like, but it's produced differently on different keys.
Third file is supposed to be a soft vocal patch, but note the "hard" attack. It wasn't there before.
The keyboard wasn't making any of these strange sounds at all and then suddenly they were there. Between that time, it never left the stand in the practice room.
