Let's see if I remember this correctly, took me some time to figure out.
-Slide the iMS-20 screen up, until you see the sequencer up top.
-You should see four square white buttons on the left: Note (default), Vol/Pan, Parameter, and Voltage. Parameter is what you want, click it.
-Immediately on the right you should see Channel A, B and C, top to bottom, on the sequencer. Underneath each of these is a dark grey rectangular button.
-If you touch one of these grey buttons, say Channel A, a list of tweakable parameters pops up. These include anything from oscillators to filters to LFOs and effects.
-From that list, select the first parameter you want to control. What you record on the Kaoss Pad will get mirrored here.
-Set up Channel B with a second parameter. Typically, you could put LP Cutoff and LP Peak on these A/B channels, modulation works well too.
-Finally, open up the Kaoss Pad panel (button at the top right of the menu bar), press the Settings button in the Kaoss Pad panel, and set your X and Y axes to Param 1 and Param 2 respectively. The status panel underneath the X/Y settings will reflect the parameters you chose in the sequencer. You can only assign these parameters to the left pad, the right one is reserved for pitch/gate. If you feel the need to reverse this, visit the Global panel (menu bar).
-When you press the REC button, any movement on the pads will get mirrored on the sequencer's appropriate knob row. You can then record over using the Kaoss Pad, or tweak individual steps directly on the sequencer.
Yea, once you do it a couple of times it becomes second nature but it's definitely not the most straightforward approach.
Protip: If you swipe a knob in the interface from left to right (a quick flick of the finger away from the center of the knob, as opposed to holding it down), it's value will change by 0.01. If you swipe vertically instead, the value will change by 0.10. This is convenient when you want to snap a controller back to it's zero point but keep overshooting by .01
