Is this possible?

In TAL Sampler make a loop that start at, for example, 1sec

Loop is short and goes on for a couple of seconds

(what i would like to know if it is possible)

to add an LFO modulation Pitch or Filter to the sound that only starts when loop starts, not before.

So for one sec no modulation at all then starts the loop and starts the LFO modulation with it too.

Was trying to figure out with the mod matrix in TAL but I didn't found a way.

Actually I use battery as sampler and it can't do it, so I'm looking for a vst sampler that can do it.

Any advice would be really appreciated.
