The doofer exposes the LFO's amplitude and offset with no problem since they're both expressed in percentages.
The LFO's frequency is defined in LPC, but the exposed Doofer control presents it as a percentage.
Could the Doofer control's units mirror the primary target's unit?
And/or could the Doofer control's units be used selectable?
[edit: reworded now that I've noticed that you can use text entry, and that my problem is with the units rather than the entry method.]
