Summary: There are several problems with this keyboard: 1. The only manual is a quick start guide that doesn't explain very much. 2. It doesn't work when playing songs in windows media, real player, audacity etc. I have a wedding band and bought this keyboard to learn songs on but it doesn't work when computer audio players are turned on at the same time as Live. I also bought it to input notation data with Encore but it doesn't work for that purpose either. 3.
Summary: The first thing I noticed was that the pitch velocity was erratic. Notes played in succession and then repeated (arpeggio) sound different each time. It's subtle but noticeable. I tested the keyboard through three different simple midi hosts (midirouter, vmpk and simplepiano) and got the same output. I should've researched this model better as the pitch velocity problem is noted at other sites.
