That’s a really easy combo do pull off. Just press the strong the same time you would have supposing you had to input a third jab in that combo. Just practice the cr. jab x 2 -> st. strong without doing the crossup mk until you get it down
I don’t really advise using audio cues if you plan on playing in tournaments, 'cause you usually can’t hear the sound 
Yea the timing is tough although I play on a controller so that may have something to do with it, today in training mode I canceled Ryu’s S.Fierce into his super once and then could not pull it off again. But man if I was able to consistently pull off combos like that it would be a useful tool.
in other games like tekken i go by visual cues
but this game with the links i just use the rhythm and i’m ok with the links on the few characters that i play
I think it’s letting go of down that gets me. I’m playing on a pad right now (never played ST on a pad before HDR) and it’s really foreign to me. But yeah, practicing cr. jab x2 -> st. strong is probably a good idea.
Edit: It’s definitely the letting go of down that gets me. I can pull off crossup j.mk -> cr.jab x2 xx MGU or upkicks every single time, without fail. Letting go of down to get that st.strong just seems really hard on a pad for me. I don’t know why. Anyone else experience something similar?
Yea that’s not such an easy combo because of the pause. I just go for something like cr. mk xx super or even cr. fierce xx super
Don’t let go of the dpad or stick. just slide from down to back and then do the mp while holding back.
That’s what I meant by “letting go of down”. Not actually taking my thumb off the d-pad 
Oh. Then just keep practicing i guess. I didn’t have any problems once I figured out the whole hold back thing. Before I was trying to release the stick and shit. 
I think I’m having trouble linking the cr.jab with the st.strong. Maybe I’m accidentally kara canceling a cr.jab because I mash the buttons? I can’t seem to precisely combo two crouching jabs if I don’t mash jab until I see two connect.
Oh you’re mashing?? Well that’s your problem right there man. It’s all about getting the timing down
You just have to have rhythmic timing I think. I do most my links like beats or a metronome. I’m a drummer so I just count out the beat to my button presses and it seems to work.
Yeah, I’ve always been a masher with combos. For most combos it doesn’t seem to really make a huge difference if you mash or not, but I’ve been told with combos involving multiple weak attacks that mashing is a big no no, but I’ve never been told why; I just assume it’s because you sometimes accidentally kara cancel a jab or short or something and screw up your combo?
I’m a drummer too! Maybe I should try that out.
By mashing, you’re kinda leaving it up to chance. Once you learn the timing, you’ll increase you’re consistency greatly. And as you said earlier, you mash until you see the 2nd jab connect. By then you probably already missed the window to input the strong, and that’s why you’re having trouble. Yea mashing is a BIG no no in ST.
