Re: Features for a new release. (was Re: [Denemo-devel] Midi output faulty for whole measure rests in 4/2 time)

[Nils Gey]

Forgot one thing.
Jackmidi in Windows is capable of software routing. So even if it does not 
suppor external midi-input it is possible to route the external data via a 
virtual midiport to jackmidi/denemo until there is an jackmidi-backend for 
windows.
