How Shure’s SM57 Became the World’s Go-To Microphone
Great article about how the Shure SM57 became the “go-to” microphone in the audio industry. For me, I like my Sennheiser 421 or Shure clip on, but I ALWAYS have a SM57 in my bag “just in case”.
When the world’s top audio engineers are asked for their one, must-have, general purpose dynamic microphone, many always answer: Shure’s SM57. Why is this $100 mic so revered? The simple answer is it sounds good on virtually everything. But with so much great new mic technology, how has this workhorse from the mid-1960s maintained its role as one of the world’s most popular dynamic microphones?

DYI BLuetooth Page Turner
The biggest issue for anyone who has an iPad and uses it for music is turning the pages. You can buy a myriad of them on Amazon. But, that is yet another thing to take to a gig. And what if you already have an effects pedal happening? It’s another thing on the floor, that you have to figure out where to put it…..so can’t you put it on the pedal board?
Pedalboard 2.0 tried to do this. But it was huge. Took up a LOT of space, even on a bigger pedal board. And I don’t like lugging around the bigger pedal board.
So, why not make one? There are a couple of DYI projects on the web to make a bluetooth page turner, one of them being this one on the instructables. However, they no longer sell the keypart of this project, the Adafruit EZ-Key. Spending some time on Google I found this great tutorial by Anthony Warren which used readily available parts. We parted ways on how to do the code though, which I’ll explain a little later. Let’s get to the parts.
The first part is an Adafruit Feather M0 Bluefruit LE. This is the brains of the whole thing. It is powered by either a battery pack or USB. The power supply on my pedal board has USB, so power is not an issue.
Next parts were the Etopars Guitar Effects Pedal Box Momentary SPST Button Stomp Foot Switches. These are in an OPEN state until you press them, and then it completes the circuit.
Wiring was pretty straight forward. Both switches share a common ground.
The whole thing was really easy to do and now I have an effects pedal with a page turner on it.
Now, the code. I chose to do the route of making the Bluefruit a keyboard replacement rather than what Mr. Warren did (where he did it via Midi). The advantage is that it is easier to pair, and it was easier to get ForScore to work. Plus I had a time deadline on it, and wanted it working before a gig. I MIGHT revisit this and tweak it some more (perhaps using Midi). Right now though, it works really well. I think I might tweak it so when you stomp BOTH Switches, it drops the bluetooth connection for a set period of time or until you stomp BOTH again. This would allow me then to use the iPad’s keyboard for a period of time. Anyhow, the code is based off the example in the Arduino IDE.

APPLICATION SETTINGS
? ? FACTORYRESET_ENABLE? ? Perform a factory reset when running this sketch
? ?
? ? Enabling this will put your Bluefruit LE module
in a 'known good' state and clear any config
data set in previous sketches or projects, so
? ? running this at least once is a good idea.
? ?
? ? When deploying your project, however, you will
want to disable factory reset by setting this
value to 0.? If you are making changes to your
? ? Bluefruit LE device via AT commands, and those
changes aren't persisting across resets, this
is the reason why.? Factory reset will erase
the non-volatile memory where config data is
stored, setting it back to factory default
values.
? ? ? ?
? ? Some sketches that require you to bond to a
central device (HID mouse, keyboard, etc.)
won't work at all with this feature enabled
since the factory reset will clear all of the
bonding data stored on the chip, meaning the
central device won't be able to reconnect.

Self Leveling Pads
Jim Schmidt has made some very interesting items over the years. Probably his most unique thing is the linear fingering system saxophones he created. He is also well known for his excellent pads that he makes.
His latest creation are self leveling pads. Check it out.
Pedalboard 3.1
I describe my previous pedal board setup here. A couple of months ago, I replaced the Nano POG with a TC Electronic HOF Mini. I found with the Eventide H9, having the Nano POG was sort of redundant. Plus, I have the Eventide H9 on bluetooth midi, allowing me to easily configure it to change patches when I switch pages in ForScore.
Having a reverb is really nice to help fill out one’s sound when dealing with different sound systems or performance spots. I still haven’t quite figured out how to get the EWI into this rig yet. The last attempt the volumes from the mic and instrument in on the Eventide Mixing Link were wildly off. Hopefully I’ll figure out a fix soon.
The other addition to the pedal board are the two switches on either side. This was a little project I did last week to incorporate a bluetooth page turner. This project will be documented in the next post.
