One problem with any complex system is the learning curve in order to effectively use it.   There are members here (and elsewhere) available to help.

P. 230 of the Modx M operation doc describes the Tx/Rx Switch screen and all of the switches on it. Turn the CC switch on and go over the list of switches. If ANY of those switches are OFF that particular CC message won't be received by that part.

You can imagine how difficult it can be to learn what each performance is programmed to do with so many switches that can affect things. Each part has its own set of switches and they will only affect things when 'something' is trying to send that particular CC message to that specific part. 

And that 'send' may only happen in special circumstances. So you can go for months without it ever happening.

You got LUCKY because slider 2 gave you visual info that something you didn't expect was going on.

Please take special note that until you gave us a SPECIFIC example there was no way for us to 'guess' what your particular issue was.

Not picking on you. But you will get the best, and fastest, help in the future when you can provide a specific example with enough info for us to try to reproduce the issue. 

You will appreciate the power and flexibility of the M models as you get more and more familiar with how things are structured.

IMPORTANT - that 'Coastal' performance, and your issue, is an EXCELLENT example of why many, if not most, of the performances are NOT necessarily ready for 'prime time' use in a gig. They usually have a LOT of programming in them meant to demonstrate various functionality.

Notice there are FIVE scene buttons lit up. That means that each scene is likely programmed differently. What does each scene do? How is scene 2 different from scene 3 or other scenes? You will need to examine each of them to learn why they are there and whether you want to use them and/or modify them.

Good luck!

Edit part 2 and look at the Mod / Control -> Tx/Rx screen.

Notice CC is OFF. Set it to ON and notice slider 2 now works. Turn it OFF and notice the slider no longer works.

Thank you for your help.

Yamaha would really benefit from a book (PDF) that explains all of the ins and outs of every Performance. 

We'd be happy to proof read your first chapter - just let us know. You've got plenty of material from your many previous posts. Why let that all go to waste?

That is the way it has ALWAYS worked as this 10 year old reply from Bad Mister explains

https://yamahasynth.com/community/montage-series-synthesizers/superknob-control-by-fc7/#post-8433

The Super Knob position is programmable - this means *where* it is when you recall a Performance is up to whomever programmed that Performance. The pedal being physical (and not motorized) must then travel to 'hook' the stored value. For example, on some Performances the Super Knob starts at 0 (7 o'clock) in which case you will need to rock the pedal fully heel down to 'hook' that value. If the Super Knob is stored at 64 (12 o'clock) you must pass through the halfway point to 'hook' the value. Stored at 127 (5 o'clock) you will need to reach toe down position to 'hook' that value... Naturally turning the knob itself being lighted and continuous-turn it simply begins where it is stored/indicated, but the physical pedal must "pass through" the value to become active. This is completely normal, and by design.

This allows for smooth pickup of the value, rather than "jumping" to the value of the pedal's position.

 

First, sliders can be turned off entirely.  If Receive Vol/Exp is turned off then sliders will be disabled.

If sliders are not disabled and nothing else is programmed to offset volume then sliders will work as you expect.

However, counter to perhaps your expectations, sliders are not the only source for impacting volume/levels.  You can set any other controller (after touch, mod wheel, pitch bend, assignable knobs, super knob, ribbon, envelope follower, motion sequence aka lane, etc) as the "source" controller for offsetting the volume.  And say your offset set by another controller offsets the volume by +127 (assuming 127 is the max - readjust to actual max) then even if your slider is in the zero position the other controller will dominate and "peg" the volume at 127 (max).   And probably the intent here is to use the other controller for volume rather than sliders.  Or adjust the other controller (say it's Superknob) so the offset is 0 and then the slider will work normally.

Yamaha would really benefit from a book (PDF) that explains all of the ins and outs of every Performance.  Why the programmers setup what they did from each programmer's perspective with gory detail about the entire setup for each Performance.  This would cover mostly the new Montage (classic) and Montage Performances without having to get too detailed on the carry over from previous gen material (Motif XF and earlier).  No one really wants to write this but even an abridged version with a mix of different Performances without being exhaustive would be good.  Something that covers enough of the surprises that one could study it and gain "literacy" on the keyboard. 

1. Move slider 1 to 0 - all the way down

2. load the Init Normal (AWM2) performance

3. Move slider 1 from all the way down to about half way up.

4. Did slider one change the volume?

The correct answer is NO!

That performance has 1 part and it has 1 element. The part volume on an M8X is set to 100 and the element Level is set to 127. On your M7 it is likely the same.

The slider is at 0 but the element level is at 127. So the slider has to 'hook' the volume level before it will control the volume. When you move the slider from 0 to halfway the slider position is still less than the current volume setting so the slider won't affect things.

5. Move the slider all the way to the top and then start moving it down.

6. When you start down the slider should now be affecting the volume

Post back if that is the sort of thing you are seeing.

Do steps 1 and 2 again and then change the element 1 level from 127 to 64.

Now when you move the slider to halfway up it will 'hook' the volume and be in control.

Because different performances have different numbers of parts with different settings when you load a performance (or use a live set) some, even all, of the sliders can be 'dead' until you move them to match the current part volume setting.

Confusing? Yes. And that is why relying on sliders to modify the volume can be problematic at a gig when you are changing performances. Because when you finish one performance the sliders could be in ANY position. Then when you load the next performance some of those sliders won't be 'hooked' until you move them to match the part setting.

And trying to manually move each of the 8 sliders to the right position to 'hook' them just isn't a reliable way to do things.

That is just one reason why knobs, scenes, and scene changes, are used to control volume (and many other things).

You need to plan ahead what the order of performances (live sets) will be and make sure they are programmed for the volume levels you want for each part.

TMI - Why did they implement it so the slider has to 'hook'? What if the slider was at 100% but the part volume of a new performance was at 0? Would you want that part to suddenly jump to 100% when you load the performance? No.

Sliders have a fixed PHYSICAL position. Full down is 0 and Full up is Max. They will almost NEVER match what a new performance is set to.

Rotary knobs have a LOGICAL position. There is no 'minimum' knob position - you can rotate it counter-clockwise as long as you want. So if you program a knob to control volume and load a performance the knob will automatically assume the value that the volume is set to without you needing to move it at all.

Confusing? Yes.

You will need to experiment to find out what works best for you to control the things you want to control.

Select one of the 'Factory Live Sets' since they should be the same as on a Montage M model.

The key thing about synths, Yamaha synths in particular, is that they only do what they are programmed to do.

Knobs and buttons can be programmed to do other things and parts can have 'expression' disabled which will disable the sliders from controlling buttons.

With a specific example we have a good chance of finding out what is causing the behaviour you are having.

something else I have noticed. In any performance for volume weather the common button is on or the individual volume for a certain instrument. I have to highlight it and turn the main knob above enter and exit. Is this normal ?

We don't understand what you are wanting to do or what the statement above means. Use a preset and tell us: 1) what you want to do, 2) what settings/knobs/etc you are using to try to do it, 3) what results you get and 4) what results you want.

That way we will have enough info to try to reproduce what you report.

Factory Live sets, Best of MODX 1 2 etc .. and some that I have put in User live sets for favorites. The volume sliders do not always work and seem to be random when M7 is booted up. Volume can be changed just not with the sliders. I am trying to determine if maybe there is a bug I have 2 days to return the unit or maybe exchange for another.  Thank you.
