Is someone using the sequence function?
I find the sequence function not very usefull, we've already the chaser function and I would propose to delete it.
I don't see the benefits of it.
Massimo Callegari

Giacomo, chasers and sequences are different things.
Sequences are fundamental for the Show function.
You don't see the benefits of it because you don't use the Show manager.

If you don't use it, just ignore it, but please don't propose to remove QLC+ functionalities you personally don't use.
Massimo Callegari

To answer your question: I use sequences. My band's project is 2.8MB big and use only sequences. There are 187 of them in it.
Paul Evans

This question does suggest a documentation issue though. I have often found myself wondering what is the difference between a chaser and a sequence; when you would use one or the other. It's something I've not really found an answer for.

Perhaps it could be better explained somewhere?
Massimo Callegari

As written in the documentation:
A sequence is a special Chaser which is bound to a specific Scene. It means that all the created steps will control various channels of the same scene. When creating new steps in a sequence, no Function selection popup will appear, since a Sequence is a child of a Scene.
A sequence will appear in the Function Manager with a different icon than a Chaser.

What is not clear ?
Have you ever used the Show manager or read its page in the documentation ?
Paul Evans

No, I haven't ever used the Show Manager. Again, I think documentation.

You've not really explained why I'd use one or the other. In what situations would a Chaser be useful? How does this differ from the times in which I'd want a Show with a Sequence in it?
Massimo Callegari

...and this is when I get it personal...

If you haven't got the whole picture clear, how can you determine that the documentation has issues or things are not clear ?
If you have doubts on what one and the other does, you should first read the documentation and then eventually decide if you ever gonna need one or both.

Chasers are good when you want to reproduce a number of different function in a pre-determined sequence.

Sequences use always the same Scene for all the steps and can be placed anywhere in time in a Show (something you cannot do with Chasers)
Also a Show groups different tracks (Scenes) so you can playback multiple Sequences at the same time.
With Chasers you should need a Collection, but still you would have a hard time to sync them.

An example. You have 30 lights total and you need to have 100 perfectly timed scenes with different colors/transitions.
With Chasers you need 100 Scenes + 1 Chaser.
With Sequences you need 1 Scene and 1 Sequence.

If you're still not happy read these:

Do you understand the difference ?

I broke my back writing the Show manager and handling sequences and now you guys suggest to remove it cause it's not clear what they do (without having even tried them)

Nice,

I'm glad you speak about sequence, because of the french translation.

This term "sequence" means cuelist in french, so it brings a lot of confusion, as the UI is quite the same as the chaser UI, we still don't know what term use to translate sequence, it will be easier if the original term was diferent as it is not really a sequence but more a sort of time instance of a scene...

Reards !

PS : very nice last versions, the 2D view is a great step for mankind !
Joe

A bit harsh maybe Massimo? I too, did not know the difference between the chasers and sequences. It's not clear in the manual.
Massimo Callegari

Ok, I'm done with this forum.
I am clearly of no help here and most of the discussions are pointless ping-pong matches.

I do you a favour and take myself out of the equation. With this, I am convinced you guys don't even try to understand. You just like to complain and point your finger.
giacomo

I think that the only one that is pointing fingers is you, sorry but this it's not the way to answer people.
If you've ever used ADB, Strand, Etc or Chamsys, the ones I know but for sure I don't have the whole picture like you, you would find that it is exactly the contrary: a sequence it's a cue list and a chaser it's a number of steps from a choosen grup of lights. Maybe there is a reason because people find it confusing.
Paul Evans

I'm not particularly familiar with any kinds of lighting software before. I've only ever used a simple 12/24 desk (a Eurolight) before this, so it's a big step up. Lots of new things, that look at first glance very similar.

I'm really not trying to point a finger of blame at anyone here. I'm trying to be constructive. My comment was that the documentation doesn't really explain what the real difference is between a Sequence and a Chaser in any detail. It certainly doesn't go as far as to explain to me how I would choose to use one or the other, for whatever effects I was looking for. My point here was to suggest "hey, here's a thing that could be added to the documentation".
Paul Evans

I for one wasn't suggesting removing them at all - by my own admission I don't know what they are for. I was simply trying to suggest "hey, some more detail in explaining is good".

The above wording is quite a bit of new interesting documentation I hadn't seen before, and I don't think could be found explained quite that way in any of the current docs. Perhaps the above could be added in somewhere to help?
Massimo Callegari

Giacomo, are you aware that you're talking about my spare time that I offer for free?
It's like if you took one year to build a house, then I see it and say "I don't understand what is its purpose, can you destroy it ?"

Your original post was quite unfair to me and to users that use the Show function.

If you think you can decide what features should stay or not in QLC+, you're wrong.
If you think you can decide how I should answer a question, you're wrong.
If you think QLC+ should work like the software you mentioned, you're wrong.
If anyone thinks that comments like "it's not clear" or "it's confusing" or "it doesn't work" are constructive, then guys, you're all wrong.
To me they're just complains without a constructive goal.

Your statement "I find the sequence function not very usefull" is one of them too, and it is what I consider "pointing a finger".
You work in theaters, so it's obvious you don't need Sequences. If you worked with a multitrack Show, with audio and sequences synced to a metronome, would you have proposed to remove the Cue list widget just because you don't use it ?
George Qualley

Guys, I have to agree with Massimo on this one. I've often looked at the sequence and wondered something similar, but I've always understood that they served a purpose and I've always assumed that they were there for a reason (and I never suggested removing them without having a full understanding of what they are for). Moreover, once Massimo explained (in further detail) what they do, I would think that someone might actually take the time to update the documentation if they find it insufficient with that information rather than continue going back and forth in this thread...
Michael Clements

The current discussion on Sequences prompted me to look more closely at them, having not paid much attention to them before as I haven't needed to use Shows to synchronise lighting to music.

I have programmed a number of flashing and colour changing effects for disco, party and “magic” scenes in various theatrical productions by building Chasers, but now see it would have been easier to use Sequences on a Show track and replay the Show by attaching it to a button or including it in a chaser step. This would have achieved the same things, but with a lot less clicks.

At the risk of repetition, a Sequence embodies an important and, I imagine, frequently used functionality of a Chaser but is far quicker to programme, as your example makes clear Massimo.

The issue of those users who have trouble understanding the differences between a chaser and a sequence and their applications has come up a number of times and it's obviously frustrating to keep on explaining the same thing over and over.

I suggest the following explanation of a sequence for the documentation (I'll sort it out in html if you're happy with it Massimo):

Sequence

A Sequence has some of the functionality of a Chaser, but can be programmed far more quickly. It is equivalent to a Chaser in which each step is a single scene and every one of those scenes controls the same set of channels. A Sequence is bound to one specific Scene, which means that all the steps of the Sequence can only control the various channels of that Scene. When creating new steps in a Sequence, no Function selection pop-up will appear, since a Sequence step cannot include other Functions, unlike a Chaser step. When a Sequence is created, a special sequence icon will appear in the Function Manager under the Scene to which it is bound.


As a result of my investigations into Sequences, I have a number of other points to raise which I will make the subject of a separate post.
Massimo Callegari

Hi Michael, this is what I call a contructive post :)
I probably have troubles in explaining a concept in english to give exactly a clear idea that I have in mind.
The texting you proposed looks good to me, except for one little statement:

"A Sequence has some of the functionality of a Chaser, but can be programmed far more quickly."
The second part of this sentence is not true. There are cases where programming a Chaser is faster than programming a Sequence. For example if you have 50 different Scenes and you want to make a lot of combinations of them, it will take less time to create Chasers than Sequences. This is mainly cause of the Function selection window.

I am going to change the documentation now.
Thank you very much.
Joe

So if someone could explain, how do I program a sequence? I am not using the shows feature, but it sounds like a sequence may be a less messy way to program a movement sequence than having to make a bunch of steps and then add them to a chaser.
Massimo Callegari

Joe, create a Scene in the function manager, add the fixtures and enable the channels you want.
Then (with the scene still selected) click on the sequence button and start adding steps to it.

EDIT: With the show manager this is much more intuitive and visually easier
Michael Clements

The speed of programming a Chaser hinges on "if you (already) have 50 scenes"! I overlooked this, I'm afraid.

Try this formulation:

A Sequence has some of the functionality of a Chaser, but can be programmed far more quickly if you don't already have a lot of scenes programmed for use in a Chaser.
