Besides using aftertouch, slider, or the modulation wheel...
So you play a sustained note for a specified amount of time and then the LFO kicks in, say 5 seconds or so.

Here are two ways there may be more:
1) you can use two lfos start with basic patch:
lfo1 = triangle, frequency 100, amount 0, dest: osc all freq
lfo2 = square, frequency 15, amount 127, wave reset on, phase 80, dest: LFO 1 Amount
this makes lfo2 turn up the amount of lfo1 after about 5 seconds (and off again after another 5)
2)you can also use the sequencer start with basic patch:
lfo1 = triangle, frequency 100, amount 0, dest: osc all freq
sequencer = play source: key, env trig/step: off, clock divide 1/2, bpm 120
track select 2 and set the dest to lfo1 amount, set step 5 to value 127 and tie to the end step 16
this makes it when you press a key the sequence starts and after 5 sec the lfo1 amount kicks in

The easiest way is always to control the LFO Amount with an envelope. Then you can control the rate of increase and decrease with the Attack, Decay, and Release, and the depth when a note is held with the Sustain.

Interesting. This is great, thanks. Gives me a few ideas to play around with too.

Is there a way of doing this without using Wave Reset on the LFO, without using envelopes or the sequencer?
-
Do it manually ;)

If the OP simply wants a delay without dynamic modulation depth, using the aux envelopes to modulate depth is probably the way to go.
See p. 34 "Auxiliary Envelopes 4 & 5," in the manual (http://"http://www.davesmithinstruments.com/wp-content/uploads/2015/04/Pro-2-Operation-Manual-1.1.pdf?765cbf").
Route an aux EG to LFO modulation depth for your parameter.
Set the aux EG's delay to whatever time you want, with 0 attack, decay and release.
Set the sustain to whatever to want; this will determine the depth of your LFO's modulation.
In effect, this acts like a triggered (and delayed) voltage offset sent to a VCA. You can play with attack, decay and release times for ramping up and dying off effects, but that's ultimately up to you and what you want to achieve with the patch.
