Excellent Drum Trigger
I was very hesitant to spend so much money for one drum trigger but it did what it was supposed to do, which was to eliminate partial or incomplete triggering on single and double stroke rolls and to have better dynamic sensitivity with grace and ghost notes. I trigger my acoustic drums, I do not put foam in the drums because I want to hear the natural sound of the acoustics, with little muffling, so I've dealt with this aggravating triggering issue for years as I'm sure thousands of other drummers have as well.
I needed a snare trigger that could have more dynamics mainly for ghost notes and grace notes in between the main 2 and 4 drumbeat without sounding all the same volume. My Alesis D4, which is a dinosaur now, isn't the best module for obtaining better sensitivity and dynamics, obviously the Roland trigger would be better suited with Roland modules but it worked very well with my Alesis D4.
I know Ddrum triggers are very good as well but I was too curious to try the Roland. If you have the money to get both, that would be a good test to see which one is better overall! Fortunately, the Roland worked fantastic to alleviate the problems that the less expensive Pintech or Red Hot triggers could not do. My only complaint is the Roland trigger is still too big compared to the others on the market. Ddrum wins in that comparison. The dual trigger on the Roland works well also but with the Alesis D4 I had to use a spltter cable to go to two channels in the back of the module to program the rim and snare sound seperately. From what the rest of the band said, listening out front, the sensitivity-dynamic issue was achieved more than 90% of the time and picking up all hits from fast drum rolls was achieved 99% of the time with the Roland snare trigger going thru an Alesis D4. That's good enough for me!
