8.2.2. Recording Control Changes in Step Edit Mode:
To record control changes (modulation) in Step Edit mode:
• Make sure the Track on which you want to record a CC# Pattern is in Control
mode
• Press Pattern + a step button to select the Pattern into which you want to record
CC# data
• Ensure Play is off and turn on step recording by pressing the Step Edit button
• Press a step button to select the step to which you want to add CC# data
• Now turn the encoder to the position you want to record. While turning the
encoder, nothing will be recorded, but you can monitor the changing value on
the OLED display. The display will indicate the number of the step to which you
can add data, the current CC number and its value. When the encoder is in the
position that you want to record, release it. The KeyStep Pro will take a 'snapshot'
of the encoder position and store it in that step.
• Continue to do this until you've filled every step with a CC# value.

♪ : If the step being edited has no existing data for that CC number, turning the encoder will create it.

♪ : Turning the encoder fully counterclockwise reaches 0, then turning it further counterclockwise
turns it off for this step. There's a dead zone before deactivation so that it is easy to reach 0 without
turning the encoder off. To turn it off, you have to turn it to what would normally be '-5'.
You may have guessed by now that there are two ways to fill CC# Patterns with data: either
you can fill the successive steps with 'snapshots' of the positions of one encoder and then
go back to the first step and continue with another encoder, or you can fill a step with
'snapshots' of all the encoder positions simultaneously and then continue to the next step
until all steps are full. Both methods have their pros and cons.
To erase the CC# data in a step, turn the appropriate encoder fully counterclockwise until it
reaches 0 then continue to turn it counterclockwise beyond 0, thus turning off the encoder
for that step.

♪ : Sequence functions such as Lst Step, Extend, Step/Page Copy & Paste, Clear Pattern and Clear
Steps all behave as in normal mode. A CC# track is always in 1/16th resolution (Time Division).
