I've had my EAD10 for just about a year and can't get over how much it has helped me as a practice tool. I still have 3 unused inputs on the module that I'd like to make use of in some way. One option would be to add a Yamaha acoustic trigger to my snare drum or toms to combine the natural sound of the drum with a sample from the module. The other option is to add a few dedicated 3-zone electronic drum pads for triggering auxiliary percussion or other sounds from the module. Has anyone experimented with either of these options with the EAD10? If so, what are your thoughts? Is it worth the effort and expense?
