View Full Version : One Step Closer to Completion, But.....

Well, I took the prevailing advice regarding flipping the piezos over so that the brass side faces up, and it did seem to have a positive influence.

I now have the module mounted properly on the Gibraltar rack, and have everything connected for the snare, 10", 12" toms, hi hat trigger and bass trigger. A couple more bridges are just a few minutes away from completion (8" tom, 14" tom) and the cymbals are still left to do.

The results? Kind of mixed. On the bright side, the Alesis DMPro really does produce great sounds. The tom sounds are very authentic, when you want them to be and it is pretty cool to literally be able to tune a drum up or down with a turn of a knob. The triggering does work better with the brass sides up, so I don't have to set the gain to the ceiling and the threshold to the basement. The response is pretty good over nearly the entire drum head of each of the drums I have completed so far.

The downside: the response so far is not what I had hoped for as far as accuracy is concerned. For example, when playing an open roll, the triggering stays with me only up until a certain point. For closed rolls, it is nowhere close, as the module just emits a volley of sounds when it gets around to it. Also, the module is just not very loud at all, and I am likely going to have to figure out how to amplify the output if I ever hope to play along with recorded music. At 44 years old, and with decades of playing and listening to loud music, and working in the music industry for some of that time, I think it is likely that I have not retained ALL my hearing, but then again, I don't think things are that bad - YET.

And finally, the two items that I bought preconstructed - the kick pedal trigger and the hi hat trigger, play at an even softer level than everything else. I have to hit the hi hat trigger so hard it is about as loud as its regular acoustic counterpart. When my girlfriend put on the headphones and played the kick pedal, she commented that you could hear the acoustic noise much more prominently than the electronic trigger, so I know it is not just me.

Oh well, back to the laboratory in a big way. I think these things are resolvable but I just have a lot more tweaking to do.

Jon,

Good news about the piezos :D .......the triggering issue may be something that just needs perseverance to track down and fine tune. Maybe experiment with cone materials and construction, etc.

Mate, re the volumes.........with the DM-5 I purchased from Bi-Polar here, there is no way in hell I can have the volume turned right up when using headphones.......it would be way too loud.........although I do agree the h/hat could be a bit louder. I haven't even had time to play with any "editing" features yet but I would presume there is a way to set the levels of each instrument "in the box" so that may be worth while investigating.

:cool:

Actually, I am now pretty sure that the volume of the module is entirely inadequate.

THe master volume on the module, that is. You can mess around with the triggering, gain, velocity curve, etc., but the fact remains, you just can't get it cranked up to anything approaching loud.

But on the other items, you are right. It will likely just take a little more tinkering around iwith the settings and/or bridges. I built these with spring loaded adjustable bridges, so if I need to back the cones away from the head, or move them closer, it is pretty easy to do.
