Nitro Max User Guide/Manual v1.1…pg 25.
MIDI Map shows Snare/Toms are Dual Zone.
Kick/Cymbals are single Zone with the exception of the expansion for Cymb 2(Crash 2) showing to use a TRS cable.
Crash 2 Trigger Input (1/4” [6.35 mm] TRS)
“Use a standard 1/4” TRS cable to connect this input to an optional cymbal pad,which will trigger the Crash 2 sound"
Check all the cymbal cables to see if TRS or TS.
The User Guide/Manual shows No additional MIDI Notes for the cymbals so they are more than likely single zone with TRS cables to allow for choking.
You’ll have to split (Y-cable or splitter box) the Tom trigger inputs to add more triggers.
You can only use Piezo Type triggers…Switch type are not compatible…No Edge…No Bell…No Choke…only the Bow of a Cymbal will function.
When splitting triggers you cannot strike both triggers at the same time as they will cancel out.
Few modules (older Alesis…Original DM10…Trigger I/O) have “Zone Talk” feature…that allowed simultaneous hits.
The Nitro Max module does not have additional articulations/samples for Tom rims or for Edge and Bell which are typically the 2nd/3rd zone on a cymbal and are switch type trigger zones and as mentioned previously are not compatible with Piezo Type (Kick/Snare/Tom) inputs.
The Nitro Max does Not have a Variable Hi Hat…it has a Continuous Variable “Type” Pedal…
The Module does not send CC4.(Pedal Position)
