Note that the switch positions have little effect on the range obtained by using CV. This is intentional, to
allow external modules control over the full range.
Because of its analog nature, the maximum and minimum rise and fall times vary from unit to unit. The
table above shows typical values.
The rise and fall times will not necessarily be equal when the sliders are in the same position. For
precisely equal rise and fall times, manual adjustment is usually needed. When applying CV to make
very slow envelopes (greater than 10 minutes), the fall time can be made much slower than the rise
time. Typically the rise time is limited to about five minutes, while the fall time can go up to 20 minutes
or up to an hour on some units.
