Organs

Instruments whose whole job is the organ. A drawbar organ makes its sound by mixing nine sine-ish footages on a set of sliders, and everything that gives it character sits downstream of that: the key click, the percussion, the tonewheel leakage and the rotary speaker it is played through. Compare the number of manuals first, because it decides what you can play and what you can carry, then whether the drawbars are physical or digital, how the keybed is contacted, and what it takes to drive a Leslie.
