Unless you want to use it for hi hats / rides etc, you can also think of it as a high passed fourth VCO that can do at least a proper square wave. I’ve been able to make a few useful pluck sounds out of some of its specific machines.
The thing I’m missing about the analog VCOs are pwm and oscillator sync. But as you say, you can get to those sounds via the digital engines instead so I’m not really missing anything. I suppose a secondary high pass filter would have been nice to cut out some of the mud, but I do that in the DAW anyway.
