The way you described it, it seems that Arp C is being triggered immediately, even though it was set on 'change on measure', while the others, the ones that really change, trigger as you would expect?

Who knows maybe this happens because it's the same Arp and it's not seen as a change? I'm making assumptions here, I'm not behind the MODX to try.

This may be worth a try: copy Arp C and store it under a different name, say 'Copy of Arp C'. Now it is a different Arp (even though the content is the same) and who knows it changes at end of measure?

Is there any setting which allow the arp to keep on looping without resetting?
Maybe there is kind of "ignore" arp (kind similar to 'off' and 'mute' arps)?

OFF is a drop dead command.

If you want a musician to not play, but continue to pay attention, you would put a musical REST on their music chart. This in the MODX is a Mute Arp at the time signature of the composition. The Arp “Mute 4/4” will tell the Part to count 4/4 time until it is given an instruction (at the top of a measure) to begin playing again.

OFF is they go on break... they no longer are counting, they are just not playing. You want them to NOT play, but you also want them to count.
So substitute the Arp Phrase “Mute 4/4” Arp Phrase number 10221 when you want to have an Arp Part “rest”

@Eldad

Not sure I'm translating your request correctly or not - but I'll take a stab.

Here's one interpretation of what I think you're saying:

Scene 1 has some things it changes. It "sets up" (changes) the ARP to match a specific ARP and also does things that are not ARP related
Scene 2 "sets up" a second ARP (different) than scene 1 - and changes other things that are not ARP related

You want to press Scene 1 and not have the ARP change from what Scene 2 started - and you still want scene 2's ARP to continue without stopping or changing.

... again, not sure if this is a correct interpretation - but it's what is assumed to be the request for what follows:

Since Scene 1, by design, changes the ARP - you can't use this to do what you want. I'm assuming that scene 3 is unassigned and free to assign to a new scene definition. If that's not true - replace "scene 3" with your first free scene.

Recall Scene 1. Now store the scene to scene 3 by holding [SHIFT] and Scene button #3 together. Your Scene 1 settings should now be set in scene 3. Last, edit scene 3 and turn off scene memory for ARP. It's an ON/OFF switch near the top of the screen above ARP (the first memory button on the left).

You can get there by pressing [HOME], then touchscreen "Scene", then make sure the top tab "Scene 3" is selected. Then next row down, make sure the button just above "Arp" says "OFF".

Now scene 3 will make all changes that Scene 1 changed except it won't touch the ARP.

Jason,

I will try to explain my use-case, not exactly as you interpreted 🙂

Scene 1 is the verse, scene 2 is the chorus.
One arp is common for both the verse and the chorus, should not break and not reset when changing from scene 1 to scene 2 or vice versa.
In another part I have different arp per verse and per chorus (slots 1 and 2).

The common arp (the first part) is set on both slots: 1 and 2. But it resets when I change from scene 1 to scene 2 or from scene 2 back to scene 1.
The common arp needs to just keep on playing without change while the arps in the other part do change.
Also, the arp is 4-bars long and should always keep the full length even if I switch the scenes earlier.

I hope it is clear now, hope there is a way to resolve it.

Thanks.

When I use built-in ARPs that are all in 4/4 time I don't see an issue changing ARPs and having one Part keep the ARP running without interruption or change and having a different Part change Arps on the measure.

I have to set the ARPs to both change on the measure (not real-time). This is what you express you're already doing.

I'm just wondering if, since you made a custom ARP, if the issue is really the way the ARP is constructed. If it's a different time signature than your other ARP - its sense of "measure" may be out of sync with the other ARP(s).

In order to do the experiment - I first setup a 2 Part Performance with a 1-Part piano in Part 1 and a 1-Part bass in Part 2.

The piano Part (Part 1) I setup the individual ARP #1 to "MA_Pf Arp29" and individual ARP #2 to the same ARP "MA_Pf Arp29". Notice in the data list this Arp is shown as 4/4 time signature.

The bass Part (Part 2) I setup the individual ARP #1 to "MA_Fingerbass1 _N" and individual ARP #2 to a different ARP "MA_Fingerbass2 _N". These are also both 4/4 time signature.

I've set all ARPs (both Parts) to hold and all switch on the measure (not real time). When I start the ARP then trigger them to get them going - I can press the ARP #1 button or ARP #2 button and at any given time the bass will start playing its new pattern on the measure (downbeat of 1) and the piano will keep doing the same thing without changing. So, in this experiment, Part 1 (piano) was constant and Part 2 (bass) was changing.

If "MyCustomArp" means these are not factory and you programmed these - then that is cause for concern. I would perhaps first start with factory preset Arps and get something simple to work -- then work your way back to figure out what's going on with different ARPs (custom user created ones).

Hi Jason,

I reproduced this easily using factory arps, even using a single part.
Select an arp in which the 4th bar is significantly different than the first three bars so you can easily 'hear' the difference, and set it to both Arp1 and Arp2 (also reproduced using factory drum kits, or any other).
If you change the active arp (from 1 to 2 or from 2 to 1) anytime before the 4th bar begins then the loop will jump to the first bar without reaching to the 4th bar.
The arp should be guaranteed to play all 4 bars, otherwise it will cause my play to be out of tune and out of sync playing live with my band.
If I switch the arp after the 4th bar has started and before it ends then everything is fine but this is an impossible mission to accomplish every time at a fast tempo.

Oh - that's different. Arps don't sync up with multiple measures. They sync by the measure. You have to time what you're doing when measure 4 is running then measure 5 will start the new ARP.

You might be able to change your time signature so your ARP does multiple "measures" of your intended time signature. And really what I mean by this is using "cut time" (our double that). If you wanted 2 measures of note information to occur in one measure - you'd play it in cut time then half the tempo. Assuming you don't break other rules of the ARP (16 different notes max) - you can enter in your ARP in cut time. Quarter notes change to 8th, 8th to 16, half notes to quarter, etc. This is in 4/4 time - just play 2 measures in one measure time. Now your ARP is going to play twice as fast - but also have 2 measures of the phrase in 1 measure time. Then you can use unit multiply (to 200%) and/or leave unit multiply alone and half your tempo. Now your phrase is playing at your intended tempo - but you get 2 measures in 1. Apply the same idea to get 4 measures into 1 -- just enter everything with "double cut time" - whole notes to quarter, quarter notes to 16th notes, etc.. and then unit multiply to 400% or cut the tempo down to 25% (120bpm change to 30bpm).

If you want something better - use something other than ARPs or change to an arranger keyboard.

An ARP with measure timing gives you one whole measure to trigger the ARP change. But does not give you more than one measure. You can't broadcast a change to occur many measures away. Not standard arps.

Thank you Jason for the information.
So I'll try to use your advise and squeeze all arpeggio data from 4 bars down to a single bar and match the right unit percentage and tempo.

Is there a way to create the new arpeggio out of the existing one, so I don't have to do o real-time recording again?
