How com so many of the ARP 2600 presets depend on a Modwheel, yet the keyboard doesn't have one. Maybe the classic didn't have one, but it didn't have a Tracking Screen or Delay either, so that seems to be a very useful addition. Especially in a day and age where many make sound with a mouse or USB controller - many of which don't have a Modwheel on them (for inexplicable reasons).
