##### Polyphony ##### Polyphony
You can reduce the maximum of parallel heared voices if needed. If you recognize glitches in sound maybe reducing the polyphony by one can help to avoid these glitches. You can reduce the maximum number of voices played simultaneously if neccessary. If you hear glitches or gaps in sound maybe reducing the polyphony by one can help to avoid these problems.

With *Note Refresh* you can influence the behaviour when playing the same note. With *Note Refresh* you can influence the behaviour when playing the same note.
For example: if you play a G5 and press and hold the sustain pedal, the next time you strike the same note, another of the maximum available tone generators will hit the note. So the note sounds double and its envelope would also run out seperate for both notes (with a corresponding time delay). This would, however, limit the maximum available notes, since the same note sounds multiple times.

##### Velocity Level ##### Velocity Level
Presets which have been programmed on some editors, like DEXED for example, would benefit from setting Velocity Level to 12. Other presets coming form other sources or editors, might sound better with Velocity Level set to 100. If you have a hard to play keyboard or just want everything to sound "louder" or "more brilliant" and you don't have to press the keys so hard anymore, you can set a higher value here.

The original Dexed offers three different routines for generating sound, all of which sound a little different. These three engines can also be found in MD and you can try out which one sounds best. *Mark 1* is modeled after an original FM synth (also in the calculation), *Modern* is more modern and more accurate and *OPL* is the attempt to recalculate the sound generation like it was done on OPL chips back then.
