There is already a larger number of device files for the Midi Connection Score for different instruments.
This means that these are instrument files that can be integrated to control your personal instrument.
For example, a Tyros device file contains all sound commands from the tyros to be able to use all sounds from the tyros in the sequencer.
Please note that these files are offered free of charge. The manufacturer cannot buy all instruments for the best of intentions and is dependent on help from other users. Therefore, there may be some incompleteness or errors here and there.
In principle, you can create and save your own device files in Score, should your instrument not be found in the existing device files.
