Well, no. Busses are not strips. Busses are not signal paths. Busses are unity gain summing nodes that facilitate many-to-one connections. Ardour depends on jack for all of its busses. with no > basic difference in the kinds of controls you'd want for each. these > days, an AudioTrack in ardour is derived from the object that defines > a Bus. the only differences are that a Bus takes input from > "anywhere", whereas an AudioTrack takes input from its playlist (via a > DiskStream) and can be rec-enabled. other than, they are basically > identical. Main outs, aux sends, and sub outs are a special class of strip that receive their input exclusively from busses. Other than that, there is no difference between these and any other kind of strip. Tom
