For example, what if your supposed 1 volt source were actually 0.98 volts. It may be that you will need to readjust the volts/octave not just because your reference voltage was inexact, but ultimately to match to your keyboard which is likely also inexact. But this you would have had to do eventually anyway. The point is that the high end compensation is almost certainly still near perfect. [If it helps, consider that you have “souped up” the high-end switching, just as though you used a faster component, and it now works in that upper range.
It was our practice to (simply) show the control inputs for all our VCOs as three parallel 100k resistors, while the accompanying text indicated that (the input stage being a summer) we could have additional inputs, variable inputs, coarse and fine manual tuning, etc. You would however almost certainly have one input dedicated to the keyboard.
Dragon delivered nearly 7,000 lbs of cargo and returned more than 3,700 lbs of cargo, including 1,300 lbs of science. Dragon is the only operational spacecraft capable of both delivering and returning significant amounts of cargo to and from the International Space Station.
