+To access them, press the Mixer button on S MK2, or Track button on A/M series keyboards, then press the 4-d encoder.
 You then use the knobs to adjust parameters.
 If you're using a screen reader, you will need to enable OSARA's "Report changes made via control surfaces" setting to have parameter changes reported.
 Note also that touching the knobs will not provide any feedback and you will instead need to turn the knob slightly to have the parameter and value reported.
 On S MK2, you can use the page buttons to move through banks of parameters.
-On A and M series keyboards, you will need to use 4-d encoder right and left to move through banks.
+On A and M series keyboards, pulling the 4-d encoder right and left moves through banks instead.
 Use 4-d encoder down and up to switch plugins.
 To return to normal operation, press the 4-d encoder again.
