Very well done video, pretty helpful, you've got very clean cut instruments, good programming.
I've done the groove trick in the past, sometimes I get too lazy to re-write everything in double-time though. There's another potential option there, though it's a bit more clumsy and I'd recommend your method over this one.
If you know that all of your kicks will be on an even beat and all your basses will be directly following that, you can set your wav channel's groove to:
That way you don't have to work in double-time. Or if you're being really boring and just doing 4 on the floor you could do this:
Groove
0-03
1-09
2-06
3-06
OR if you only need it in isolated cases and want the rest of your groove to be steady you can always change it temporarily and then change it right back. Assuming The 03,09 groove is on G-01:
KICK G-01
BASS ---
--- G-00
All of them sound exactly the same, but some might fit your use-case better.
Also, very nice kick, sounds punchy.
