Tthe Master Effect Eq Gain arrives in a newly created or blank Kit by default at maximum, similar to how the individual volume for a new drum is at maximum.
Just as reducing the individual volume for an individual drum to around midday is advantageous for the tone, same goes for the Eq Gain.
Whereas the Dynamix Master Effect doesn’t require adjusting as it’s makeup gain is set to zero by default in a new or blank Kit and isn’t effecting anything.
But the Master Effect Eq Gain, it certainly is adding some digital volume boosting to the overall signal, possibly too much than is desired.
Anyway reducing Master Effect Eq Gain to around midday does seem to help coax mellow and glassy tones more easily from the Machinedrum.
Easily overlooked yet worthwhile mentioning, the fabulous yet complex environment of gain staging.
