Hi Tobias,
It is really the same issue. You seem to be stuck on the Factory provided data. Once you begin to make your own you will not be surprised by how something is behaving. Here’s what I mean...

You use the word “normally” over and over... there is no normal or abnormal... There is only how you want something to behave. And how it is programmed in the current LIVE SET program you are working on.

What’s normal?

If you start from one of the Factory provided LIVE SET *examples* (we’ll call them *examples* because that’s what they are)... and all you do is swap the instrument - why wouldn’t it inherit the settings for that Section. In other words, if you start with 1-1 “Natural CFX” and you Shift the octave down -1, and apply a Chorus Effect, and set the Volume 3/4 of the way up, then you change the “CFX” Piano to the “S700” Piano using the yellow toggle switch... the S700 will inherit the octave shift, the Chorus Effect and the Volume 3/4 of the way up... well, it also inherits all the current “Settings”... all you did was plug a new instrument into the channel. The Live Set location is still called “Natural CFX”, even though you substituted the “S700” piano in place of the “CFX”... Like every other setting, the name of the Live Set is inherited, as well.

Move to page 12-1, which should be an “Init Sound”. Page 12 through 20, are all “Init Sound”... study the “Init Sound”
P = Piano Section — default sound is “CFX”
E = Electric Piano Section — default sound is “Rd78”
S = Sub Section — default sound is “Mellow Pad”

Please realize three sounds are always stored when you store a Live Set location whether they are active or not, the sound selected for that Section is stored along with all the Settings of that Section.

You’ll discover all Parts default to Receive all Controllers (means Sustain Pedal is On)
I say Study the “Init Sound” this way you understand what the “starting point” is... you can customize a program any way you like.
But if you change the Sound in a Section, that is all you have changed. Each Live Set location (there are 120 of them) could have a new “normal”. That’s up to you!

I recommend you Start with an “Init Sound”, this way you’ll get used to how things DEFAULT.
What you are doing to confuse yourself is... You are starting anywhere, and then saying something like “it behaves normally” or “it is behaving abnormally” — when actually, it is behaving exactly as the programmer programmed it. Once you begin to make your own Live Set program and then name and store it... then you will know what is normal and abnormal for THAT program.

The beautiful thing about the Factory data, they are truly only suggested examples... if how it behaves is not *your normal* change it and STORE it. Be sure to give it an appropriate Name.

Hope that helps.

Extra Credit:
Say you are going to start the evening playing an acoustic piano, and in the next number you need that piano layered with a string pad
You might start with an “Init Sound” location
Place “CFX” in the P-Section, place a string pad in the Sub Section.
Set the Sub Section so that “Controllers” > “Receive Switch” > “Sustain” = On
Flip the Sub Section Off
Press [STORE] name it “Piano +String pad”
When you initially recall it the piano is across all keys... add the string pad when ready by just flipping the S-Section switch

If you need to move from acoustic piano to a a situation where you add a split bass, you would create a new Live Set that has the acoustic bass sound in waiting under the Sub Switch. You can have pre-programmed the Sub Sectionto Receive Switchfor Sustain to be Off...you don’t want the bass to Sustain with the pedal. Name and Store this Live Set program as “Piano +Bass”. You can play the acoustic piano initially upon recalling this program, and activate the SubSection when you’re ready to use the split bass.

You make your own normal. In the E.Piano Section you can what ever you need next sitting there “in waiting”... all you’ll need do is activate the Section Switch.

Summary: A Live Set is a set of parameters Settings that apply to each of the three Sections (whether they are active or not) in fact, whether they are active or not is one of the settings stored in a Live Set. The instrument sound you select can be freely swapped... but it is exactly like unplugging one instrument from a mixer’s channel and plugging in a different instrument. You inherit the mixer settings.

You need a Live Set where Normal is S-Section Sustain Receive Sw = On (for sustaining sounds)
And another Live Set where Normal is S-Section Sustain Receive Sw = Off (for Bass sounds)

Yes, you are undoubtedly right.

Everything works as expected now with the init setup ... and absolutely normal 😉

Presumably, many CP73 / 88 customers will try to adjust presets first. Well, you never stop learning.
