Polymeter + NEI is false Trig Condition + kick side-chain

Hi all,

As illustrated below, I am trying to use the NEI is false Trig Condition to mute the notes on a 5 note long melody track when the kick plays on the first beat of a four note long neighbouring track.

X000X000X000X000X000 and so on for the kick track.
X0X00X0X00X0X00X0X00 and so on for the melody track.

The intention was to use this polymeter appoach to make an interesting rhythm with the melody notes being automatically ducked (muted) when the kick was being played - beats 1 and 13 in the above example. However, I cannot get this to work, even if I delay the melody track notes a touch using micro-timing.

Does anyone know if this is possible?

Many thanks in advance.

I don’t use NEI much, but I think it reacts to the previous track trig-condition state.
So try with a /FILL (no FILL) condition on your kicks. It should trig the NEI condition.

Trying it here with no luck either. I think the reason is that NEI can only look at the last conditional trig on the neighbour track, not the neighbour that trigs at the same time.

LyingDalai was suggesting adding the -FILL trigs as a way to let the kick play every time. a TRC of 100% does the same thing.

It seems like it should work but NEI condition is a weird one, never found a proper use for it cos i always hit roadblock with them. Just like this…

I think that Fill relates to the Trig being active if the sequencer is in Fill mode (eg. see page 39 of the Digitone manual).

Can someone from Elektron please enlighten us.

figured it out…

track 1 - kicks:
X 0 0 0 X 0 0 0 X 0 0 0 X 0 0 0
set all X trigs (kicks) to -FILL (or 100%)
set all 0 trigs to FILL (they won’t play unless you hold the FILL button)

track 2 - melody:
set all trigs to -NEI

that will duck the kick in the melody track.

Hi Garf - you are a true genius - thank you very much.

Please can you share the explanation behind this - what is it about the Fill is true and Fill is false Trig Conditions that enables them to recognised by the NEI is false Trig Condition, whereas standard Note Trigs are not?

FILL/–FILL are just a way to tell the ‘listening’ neighbour track that something is on (–FILL) or off (FILL). You could instead use the 100% and 1% TRCs, but there is no 0% TRC so you’ll get occasional random plays.

The example i posted above can be simplified, might make more sense…
Try this on the kick track:

X 0 - - X 0 - - X 0 - - X 0 - -
set all X trigs (the audible kicks) to –FILL
set all 0 trigs to FILL

The 0 trigs let the neighbour track know that nothing is playing. If they weren’t there, the neighbour track would only ever read the –FILL/‘on’ trigs, and therefore would never trigger the melody sounds with the –NEI trc.

Basically, you need to tell neighbour tracks what’s not playing as well as what’s playing – they don’t read empty trigs as ‘nothing playing’. It’s a weird one to wrap your head around!

Thanks again Garf and this (admittedly in an Elektronesqe way) makes sense.

Thank you for staying it more clearly.
Indeed, NEI watches the previous track condition, so you have to set conditions there :slight_smile:
