Blog article about basic signal flow

That was actually interesting reading (who knew so much went into one snare stroke)?
Now if you could do a similar article using an e-drum snare as an example that would be great!

That's a great article Luke, & enlightening for those not so involved in music. for those who already know this stuff, it's a reminder of just how far the recording & replay process has evolved.

From the point of hitting the head with a stick:

The stick hits the head, the piazo cristal in the drum creates an electrical pulse based on how hard the head was hit (piazo cristals create electrical pulses propotional to how much they are deformed by preasure or a strike). This travels to the drum brain where it is measued and converted to a digital signal by a simple analog to digital converter. This signal now is a digital measure of how hard you hit the drum. This travels to the main procesor in the drum brain, which then chooses an apropreate sound sample (in this case a snare sample) adjusts it volume and then sends it out to the digital to analog converter to be transformed into an alog signal that we can hear.

After this it would be the same as either going into the recording device instead of a microphone, if you are recording it, or right to the speaker inputs if you are just listening.

I may do that article in the near future! I also want to write about stuff that goes on in a DAW, there's SO much stuff that happens even in simple digital signal processing, it's crazy! Technology boggles my mind...

It really is amazing! And 10ms is a high estimate, I can get latencies lower than 4ms. It's just insane! Physics!

Yup, that's basically what happens! More and more often though, it goes ADC -> MIDI -> interface -> DAW -> some drum triggering software. That's the way to go! Why use the module, when you have modern computers, and such incredible sampling software?
