Exactly. Public events for straightforward sequencing (in any sense of the word) would be great as well. We do have public classes and they are great for what they do but I dislike them for impulsive sessions as you only get to define them once so you can't extend them.

Because the DAC already also works as a internal bus, in a way (dac => LiSa l => dac; //is fine) I imagine adding something called "bus" that operates exactly like a dac aside from not sending data to the soundcard should be a more or less straightforward addition. The one issue (difference) I see right now is that for the DAC we need to set the max amount of channels at startup but that might mainly be a matter of communicating with the soundcard.

If we would have public Ugens the whole issue would become moot as you could simply go;

public Gain bus1 => blackhole;

But I wonder how hard that would be to implement. If it were easy we probably wouldn't have the current situation with static members of public classes....
