the eq and fx areThanks DrumWagon. That sounds similar to the trigger limitations of the TD6...I don't use a Zendrum but I do use an Alesis DM10. This is a link to another forum (DMdrummer.com) so I hope I'm not breaking any rules by posting it. I believe this should shed some light on the matter:
Anybody with a DM-10 chime in

In short, there are 35 additional sound locations accessible through midi. Each one of the 35 sound location are totally editable. Meaning FX, EQ, Decay, Sounds (for both Layer A B). There are no restrictions on which of the internal sounds can be used. Any of the 1000 plus sounds can be assigned to those locations. I hope that helps.
