hi,<br /><br />i&#039;m totally new to this but am really interested in building a drum module. i&#039;m reading up everything i can on understanding schematics and hope to tackle this fairly soon.<br /><br />i have two questions. first, let&#039;s say i put two piezo sensors into a single drum pad, and have each one go into an input in the drum brain. i would assume two equally strong midi messages would get sent out into my laptop, and i&#039;d hear an identical snare &amp; tom (or whatever the two inputs are assigned to) hit?<br /><br />secondly, and i&#039;m mostly hoping for confirmation on the feasibility of the following (to the best of my knowledge a schematic for this does not exist): let&#039;s say i have a drum pad with two piezo sensors in it as illustrated above. would it be possible to build a drum machine that takes the two separate signals (that occurs when the pad is struck) and proccess each one in a slightly different manner? more specifically, take the &#039;first&#039; signal and have the strength of it determine a particular channel (ie snare, bass, hi-hat, whatever), and then take the &#039;second&#039; signal and have it determine the velocity/attack/usual parameters (like it normally would) and then send that message out taking into account the &#039;channel&#039; determined by the first? so, for example, if i struck the pad &#039;quietly&#039; the signal from the first piezo would tell the drum module to use a snare drum, and then the second piezo would tell the drum module to use a &#039;quiet&#039; snare drum hit. and if i struck the pad really hard, the signal from the first piezo would tell the drum module to use a crash, and then the second piezo would tell the drum module to use a really loud crash.<br /><br />i know it sounds a little stupid (ie the whole purpose of velocity would be defeated since each instrument would automatically get a certain &#039;loudness&#039; assigned to it) but this is exactly what i want. do you think building something like this would be at all possible? do you see any huge problems in what i&#039;m describing? let&#039;s assume i just wanted to use one of these pads (ie two inputs) - would building something like this be completely different from the edrum, or would it just be a little different?<br /><br />also if anyone knows of any good beginner documents/material online i&#039;d appreciate it. i have 0 background in building anything mechanic and all these schematics are just confusing as hell to me!<br /><br />thanks!
