What maybe confusing is that, in fact, when you press RECORD in the sequencer all tracks, do indeed, go into record. Every Part has its own dedicated Track. If you can play/hear a Part - you’re set to record it.

So you do NOT set a Track to record as much as, if your Keyboard is in touch with (triggering) a Part, or multiple Parts, they are simply recorded to their Track. If you can hear respond when touch the keys then it will record data to its own track.

If you want to record one Track at a time use the following simple template to proceed:

From the HOME screen tap the letters “FX” on the very top line of your screen
Set the KBD CTRL LOCK = ON
Return to HOME

This will place your synth in a state where you will only be able to transmit to and therefore, only able record a single Track with a single Part at a time. The act of *selecting* a Part means you are prepared to play just that Part with your Keys, Controllers, etc. (During the record process you can ignore the KBD CTRL icons — you only need to *select* (tap) the Part you wish to Record, and go).

While the KBD CTRL LOCK is ON, only the Part you directly select will sound
While the KBD CTRL LOCK is ON, only the currently selected Part will be recorded

Next:
Start with an initialized MULTI Performance.
Press [CATEGORY]
Set “Bank/Favorite” = All
Set “Attribute” = All
Select “INIT” > “Multi/GM”

This creates a Performance with sixteen ‘placeholders’, one in each Part.
When you select a Part, 1-16, you are immediately in touch with it.
Starting with any of 16 Parts, begin your Search to replace the placeholders one-by-one…

In this state, only the Part slot you *select* will sound… and since each Part has its own correspondingly numbered Track… you can proceed to record one at a time (traditional sequencing)

Select, for example, Part 1
Press [CATEGORY]
This will launch the “Part 1 - Category Search”
Set the “Bank/Favorite” = All
But this time set the “Attribute” = Single
This will limit your Part search to the more than 1350+ Single Part instruments found in the synth’s Factory set, along with others you’ve collected in your User Bank and/or installed Libraries.

In this scenario: You will not be using the KBD CTRL icon while recording… if you plan to, ultimately, “play along” on top of your sequence, then you would activate the KBD CTRL icon on the Part, or Parts, you wish to trigger live. Once activated then STORE > and NAME your new User Performance.

Try this methodology (approach) to sequencing to the Pattern Sequencer.
Attempting to record Multiple Parts to the sequencer, simultaneously, before gaining a thorough comfort zone with Single Part programs can lead to confusion.

Hope that helps.

Extra Credit:
After mastering a Single Part method that works for you, try adding one Multi Part instrument to your workflow by adding it to your single Part Tracks… example, lay down a Drum Track (1), then overdub a Bass Track (2), then see if you can add a 2-Part Keyboard simultaneously to 3 and 4.

thank you, got it to work!
