Of course, some things depend on the original MIDI file. There are also differences in quality.
Well, the sound quality depends on many factors. This starts with your own playback instrument. For example, a Yamaha Tyros will almost certainly have better effects and settings than a Yamaha PSR-433. And depending on what you use for a loudspeaker system, you will also hear a difference in quality. Etc. etc.
These are just a few of the reasons why everyone should adapt their midfiles for themselves. The midfile producers can't possibly offer the songs for every single buyer!
In the sequencer of MIDI-Connections Light and Score all settings of a MIDI song can be adjusted to your own wishes.The basic settings such as sound, volume, panpot and reverb can be adjusted in the mixer for each track. All controllers of the tracks are listed in the event list and can be adjusted as required.
