OK, so SID-Wizard will not work MIDI-wise with emulators, if I understand you correct.
I found the "Resource Inspector" window in VICE. In there under Peripherals/Cartridges/MIDI you can edit some settings. Enable, Name, Port Names, Type (Passport, Datel, Maplin, Namesoft, Sequential). This very much looks like a built in midi function, but no VICE midi ports show up in my system.
Maybe I need to put in command line text in to VICE "Monitor" window, but since there are the above mentioned settings I would assume that those settings were enough.
In MIDIslave I select Sequential as interface, and I also choose that one in VICE. I get this in the Console window:
MIDIdrv: Opening MIDI client 'VICE'
MIDIdrv: Error - Error creating MIDI client!
Is there a forum for VICE and/or a wiki?
However, MIDIslave a the first try got some input, midi feedback. Turning of and on MIDI Enable in VICE changes the speed of the feedback, so I guess that is a good sign.
Thanks a lot for your help, and sorry for the trouble.
