no problem, we surely want to do a new tutorial, but it’s just a lot of work and Andrew set quite a milestone there, to cover all of this will require a lot of filming :).
Regarding your questions:
“Mix Event Mode Dir Divider…” are available when the Menu button is pressed and then accessible via the upper Matias row of “General Purpose Keys”.
The upper info of "G1T1 Out1 Chnl.1 PANote TA:Gate Step14 C3 Vel:100 Len:75% No Cat " is not really associated with the second Matias key row - it’s just a general status info - where you are at and which note you are looking at. Of course, you could use the second key row to navigate, e.g. choose a different track. Then the top info “G1T1” would change.
The secondary row generally is just an “on/off switcher”. For example: if your radial second-row-selector button is set to “Track”, you can use the second row of keys to simply choose one or multiple active tracks. This only needs a single keypress per track selection - in the previous SEQ v4 you had to select via group and track-within-the-group first (G1T1 -> two key press actions required).
Another example: if the secondary Matias key row is e.g. in Mute mode, you can mute/unmute any track, independent from the “main SEQ screen” you are in. E.g. you could be in an edit screen where you can set the length (always with the OLED and the upper Matias row) and still have the mute/unmute functions available on the secondary selection row.
So, the OLEDs are always associated with the upper encoders and the upper row of Matias switches - most of the SEQ (e.g note editing, track configuration like length etc) can be controlled from there.
The track grouping of 4x4 comes from earlier on, MBSEQ has been available for many years!
It’s also grouped like this by design - a group of 4 tracks is called a “pattern” and you can switch through/exchange patterns and thus replace multiple melody/drum output tracks at once, e.g. if you’re performing a live session and want to alter sequences, more than one.
If you have any other usability questions or would like to see screenshots of the SEQv4+ for a certain usecase/question, please do tell, it’s not a problem!
Best regards,
Peter
