Hi Siem
it's *strongly* adviced you download the database from the unit, not from the web.
The ones we have on the web are for Vsig testing and are not updated, so they may not reflect the exact modules database in your OS version. Vsig has a Get Dbase command for the purpose.
Serial port settings are the default ones in SETUP > MIDI menu, in your H8000. Make sure the parameters are the same in the computer. Better checking them under Hardware management in Windows.
There is no in line monitor for DSP resources. You can only send the sigfile to the unit and chek if it gets loaded.
For highpass you can use the FILTER module.
best
