Using VDJ 2023 ...

When I press Ctrl-E I'd like the foll to happen:
1) Identify currently PLAYING Deck
2) Trigger ECHO OUT effect (ECHO OUT effect is already active in that deck)
3) Set Crossfader Midway - 50%
4) Wait 4 BARS
5) PLAY other DECK
6) Stop ECHO OUT on the Previous Deck

If there's any other step I'm missing, kindly offer your advice.

deck active - specify a deck, deck active being the loudest as calculated by crossfader and upfader positions
effect_active 'echo out' on - call the effect on
crossfader 0.5 - set the crossfader
wait 16bt - make the script wait a period of beats
stop & effect_active 'echo out' off - stop the deck and the effect
set_deck `get_deck & param_mod 2 & param_add 1` - we now want to specify the other deck, so get the active deck number perform a modulus 2 operation on it [if active was 1 the number stays 1 because it is < 2, if active was 2 the number wraps round to zero] then add 1. That has specified the non active deck as the script focus
play - play the newly specified deck

deck active effect_active 'echo out' on & crossfader 0.5 & wait 16bt & stop & effect_active 'echo out' off & set_deck `get_deck & param_mod 2 & param_add 1` & play


This kind of thing, [and most other script] is covered here

Thanks LOCODOG for breaking it down so lucidly.
Much appreciated.
I'm a little challenged at this scripting stuff :(
 
Edit seems you figured out a fix, here's what I wrote while you were editing
---
Indeed, deck active is a dynamic deck specifier.
effect "Echo Out", isn't a valid verb, it's effect_active

You could fix your script with the above, but here's what I suggest

deck active set_deck `get_deck` & effect_active 'echo out' on & crossfader 0.5 & wait 8bt & stop & effect_active 'echo out' off


deck active - specifies the loudest deck is the script focus
set_deck `get_deck` - this gets the deck number of script focus and changes the focus from the dynamic deck active to a static deck number.
 
EDIT ... Thx for your solution above ... Yes I was fiddling with my script & updating my post :)
a) Your get_deck ... does it have to be in quotes ?
b) I've modified my workflow as below ... how to get the below sequence functional ?
Thx!


So this is how I've modified the script:

deck active effect_active 'echo out' on & crossfader 0.5 & wait 8bt & stop & deck left effect_active "Echo Out" off & deck right effect_active "Echo Out" off

After pressing Ctrl-E ... I wait 4 bars and then manually start playing the other deck. Org Deck automatically stops after 8 bars.

I'd like to automate this a step further:
deck active effect_active 'echo out' on & crossfader 0.5 ... so far, so good

Now ... wait 4 Bars | Start Playing other Deck | Wait 4 Bars | Stop Org Deck | Switch ECHO OUT to OFF

TIA
 
Another problem I'm facing:

The ECHO OUT= OFF setting at the end of my script doesn't get activated.
However, If I map the ECHO OUT to another key, then it works.
But that involves pressing 2 keys ... 1 after another.

I'm at a loss here ...
DJ'ing for a Multi-Genre Wedding in a couple of days and Music has crazy BPM variations ... so wanted to use the ECHO OUT as my escape hatch.
