Eliminating noise in the TEX FX Signal path?

[Zurechial]

I play synths in a melodic metal band ( www.valediction.org ) and for my current live setup I use my Triton Extreme as my main synth for orchestral patches, strings, choir, piano etc whilst I use my Z1 mainly for my lead during solos.

I have it set up such that the stereo L & R signals from the Z1 go through my Triton, using the Triton's MFX bus to apply FX to the Z1 signal, whilst using the IFX for FX on my Triton Combis and programs, then the Triton combines its own output signal and the Wet Z1 signal together to go the main L/R output bus.

This gives me a really rich tone for my Z1 lead that just isn't possible with the Z1's weak FX processing, and I'm really happy with this setup as it keeps things simple for me on-stage while I still only need a stereo input to the FOH desk but...

I use the Overdrive/Hi-Gain Amp Sim. MFX patch as MFX1 in that signal path and it introduces an annoying buzz/noise signal into my overall mix from the Triton.

For the sake of a clean sound (without mucking about with external noisegates) I'm looking for some means to to silence this noise.
Pulling the master EQ's high value down to -18dB eliminates the noise, but also ruins the sound produced, so that doesn't work for me, nor can I use a parametric EQ as an insert effect to EQ-out the noise, since I'm using the IFX and MFX as separate buses.
Since the noise is drowned-out when actually playing, a noisegate would do the trick.
There are a few 'gate' options to use as alternate modulation sources for the output level or wet/dry balance parameters in the MFX1, but I'm assuming using them as a noisegate is beyond the functionality of the system.

If anyone can help me out here I'd really appreciate it.

If anyone can correct me on this I'll be glad to be humbled.

I think it's the OD/Amp Sin effect. Whenever you use distortion, there will always be a bit of noise. I have seen this without using Z1 in my Triton Extreme and my Triton Studio. I usually don't mind as distortion (Over Drive) is just that.

Hell, I get the same thing when using my Kurzweil Mangler Distortion effects (which I channel into the mixer for voice effects. This setup is really noisy).

There are quite a few effects that add a certain amount of noise even when you aren't playing anything. Think about guitar players using basic floor pedal effects. I'm not sure a noisegate would eliminate the entire problem but I'm sure it would help. I would say try turning down the gain (like you have) but not too far and turn up the mixer. At low volumes the effects need more gain but in a live situation you would be surprise how far a little will go (sort of like the bass player always turning himself up when everyone hears him just fine).

I know you don't want to take up too many channels on the mixer but it might help to run that lead sound out of an individual out so you have more control over it both in the keyboard and the mixer. I do this with drums and found it very helpful with the valve force effect. I hate to say it but I don't think there is an easy answer. Sound has as many variables as the musicians who play them. I have spent countless days and weeks tweaking my equipment and - guess what!?!? I'm never happy... The people listening to the music compliment our sound but we musicians are the hardest to please.

Hopefully, someone with more soundman experience can give you some better answers.
