Ahhhh, I love this board! Great answers guys. The bottom line I guess, is do what sounds best to you. As with everything, some opt for ease of use, some for playability; some for realism, some for technical detail; some for simplicity, some for complexity! A lot depends on the person's personality maybe? I like to be up and running quickly, and the portability is great with the TD-10, as are all the various options I have, including using melodic voices with the Z4 setup making it much easier now. We were rehearsing a song, the bass player said, "Can you get a snare with a longer gate time, with reverb, and a 'snap' like an echo-ey thing?" Sure thing boss! 1 minute, got it, and it fit beautifully with the song. I am still learning a lot of the nuances of the TD-10, and MIDI, and the zendrum. Bottom line for me, I don't really want to spend the time trying to set up a whole new sound with new software, as my life is busy and complicated enough! So for me, its "keep on keepin' on" I guess. Mostly due to time constraints, I will probably stick with the TD-10 for now, as I am still trying to learn all about that! Especially with the Z4, I want to add melodic voices and such, and I am still trying to figure out which pads on the zendrum should play what sounds for each song! In fact, there are so many choices to make, it's one of the things that initially put me off when I first started to try and learn how to play it. Hell, banging skins and cymbals was a lot more intuitive for me! Now, I have had to learn to play all over again! Thanks for the great replies all!
