I spent two years trying without success to sit the trot, then learned in one ride. No, that isn't a canter, but on my horse the wave is about the same height, just choppier at the trot...if that makes sense.
Anyways, I lengthened my stirrups long enough that I had to home them - put them between the ball of the foot and the heel - to keep from losing them. I put my feet slightly forward, and then trotted. And suddenly it worked. I was so deep in the saddle that the trot motion didn't toss me as high, and with long loose legs, my legs absorbed some of the bounce.
I did that for about 2 months, and then shortened my stirrups a hole so I can keep my heels down a bit - but now the motion feels natural. If in doubt, I roll a little to my pockets and check that my back is straight - NOT leaning forward.
If need be, go ahead and grab the horn with one hand and concentrate on loose legs, relaxed back. Use the horn to shove your butt deeper into the saddle.
Hope that helps, but I'm a real beginner myself...so good luck!
