Re: SPD-S vs SPD-SX
I've only used the SX and I love it.
There are a few features the S had that I wish the SX had.
1. Velocity sensitive layers. The SX can have 2 wave assigned to a pad. But they both play at the same time. on the SPD S, you can set them so a lighter hit triggers one wave and a harder hit triggers the second wave. Not so on the SX.
2. The phrase loop feature. The SPD S has a built in sequencer so you can create loopable waves very easy. The SX takes a few more steps and you need to do some math work to create a loopable wave right on the unit.
even so, I love the SX and recommend it.
