I have spent the last few years building a musical playground that allows me to create jams on the fly when I livestream on my <u><a href="https://www.twitch.tv/notesandvolts" rel="nofollow" target="_blank">Twitch Channel</a></u>. I've been slowly refining this process and learning how to be a one man band. I recently got to perform at <u><a href="https://www.twitch.tv/videos/1444843687" rel="nofollow" target="_blank">Synthfest</a></u> which put my skills to the test.</p><p>I discovered a great piece of looping software called <u><a href="https://youtu.be/Hd-9ZUv2Nzg" rel="nofollow" target="_blank">Endlesss</a></u> that greatly simplifies capturing my ideas in real time. You just play and hit a button to capture a loop. This works great - until I pick up my guitar. Then my lack of free hands makes looping an awkward proposition. The solution - a footswitch!</p><p>I designed a simple four button footswitch that puts out a Midi CC command when the switch is pressed. This is mapped into Endlesss to record the loops. Simple! I call it the EDLS-FS (pronounced as "Endless FS"). It's a very simple project that makes a great introduction into Midi controller design.</p><p>Watch this video for build instructions:</p><div class="separator" style="clear: both; text-align: center;"><iframe allowfullscreen="" class="BLOG_video_class" height="266" src="https://www.youtube.com/embed/H3WevrsmO9o" width="320" youtube-src-id="H3WevrsmO9o"></iframe></div><br /><p>Parts List (with Amazon Affiliate Links)</p><p>1 - <u><a href="https://www.mouser.com/ProductDetail/Hammond-Manufacturing/1590BX2BK?qs=kHy2Dt%2FAQzsBBoaWpsoFBA%3D%3D" rel="nofollow" target="_blank">Hammond 1590BX2-BK</a></u> Enclosure</p><p>1 - <a href="https://amzn.to/3kuYaqs" rel="nofollow" target="_blank">Teensy LC</a> Microcontroller</p><p>4 - <a href="https://amzn.to/3s3dIWO" rel="nofollow" target="_blank">SPST Momentary - Normally OPEN</a> Footswitches</p><p>1 - <a href="https://amzn.to/3KDI7l6" rel="nofollow" target="_blank">USB B to Micro USB</a> Panel Mount Cable</p><p>2 - <a href="https://amzn.to/3F2kDVg" rel="nofollow" target="_blank">Rolls of 22AWG</a> - Stranded Wire</p><p><br /></p><p>Tools Used</p><p>- <a href="https://amzn.to/3LBlZZU" rel="nofollow" target="_blank">Soldering Iron</a></p><p>- Drill with 1/2" <a href="https://amzn.to/3vxo8jI" rel="nofollow" target="_blank">Stepped Drill Bit</a></p><p>- Automatic <a href="https://amzn.to/37R1xWk" rel="nofollow" target="_blank">Center Punch</a></p><p><br /></p><p><br /></p>Davehttp://www.blogger.com/profile/11880269200825310805noreply@blogger.comtag:blogger.com,1999:blog-6982486148927992125.post-61503948743109867212021-05-06T03:24:00.000-04:002021-05-06T03:24:02.769-04:00Project C.H.E.E.T.A.H.<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhIVK4WWREEJ9uMLuK5nvS1XoiQnV8IceaWdesKFK-6UImFwjK1BAvgSIdAel9kS9Go7S4AcUC2wzaOTozmVCt5BgNd0OAFZVgupbJohrWHdMuANx8Um_hYnTP4RQgYmLmlFRsUJL29gB4/s2048/CHEETAH_1.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhIVK4WWREEJ9uMLuK5nvS1XoiQnV8IceaWdesKFK-6UImFwjK1BAvgSIdAel9kS9Go7S4AcUC2wzaOTozmVCt5BgNd0OAFZVgupbJohrWHdMuANx8Um_hYnTP4RQgYmLmlFRsUJL29gB4/s320/CHEETAH_1.jpg" width="320" /></a></div><p></p><p>The goal with project CHEETAH is to build a box that makes you sound like a Synth Wizard without really knowing what you are doing.

I have explored many techniques in my quest to come up with a cool looking enclosure for my projects, but this latest experiment may turn out to be one of my favorites.<br />
<br />
I have been designing circuit boards for many years but for some reason I never thought to use a PCB for the faceplate of the project. It makes total sense when you think about it. Circuit boards come in custom shapes with precisely milled holes and cut outs. And silk-screened graphics are par for the course. So, I decided to try to make a custom front panel using a black circuit board from my friends at JLCPCB. The results are amazing! And they do all the work.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEht1Tlh9n_GN4ttSQwxDygzk6HMq1qbNhjBj7pNkTtTFMqad4IP5wvAHXCaGTwMYqU5zg36BzV__BQNKmSar2Fv_PVzCyGvKzIeGshlLVTzZYLLYe0OhKWI9EV1yCHnarW_WbucC4Wl5K8/s1600/Black+Circuit+Board.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="676" data-original-width="902" height="239" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEht1Tlh9n_GN4ttSQwxDygzk6HMq1qbNhjBj7pNkTtTFMqad4IP5wvAHXCaGTwMYqU5zg36BzV__BQNKmSar2Fv_PVzCyGvKzIeGshlLVTzZYLLYe0OhKWI9EV1yCHnarW_WbucC4Wl5K8/s320/Black+Circuit+Board.jpg" width="320" /></a></div>
<br />
<br />
I used Fusion 360 to design the board and Inkscape to draw the graphics. The final step was to import the files into KiCAD and finish the board. I have to admit, getting all these programs to work together was a challenge - so I documented the entire process in the following video! Take some time and follow along and you'll be designing your own custom faceplates in no time!<br />

The Traktor software has a Loop Recorder included but unfortunately, Native Instruments removed the loop controls on the MkIII. No big deal, we'll build our own!<br />
<br />
I call this project the LOOP-R and it allows you to easily access all the loop recorder commands with the push of a button. Watch the video to learn how to build your own on a breadboard.<br />

During one of my streams I met a couple of really nice German guys who are the creators of the <a href="https://getintouch.rootfrogs.com/" rel="nofollow" target="_blank">GetInTouch</a> extension for Twitch. I was very impressed with the Arduino Library they created that can easily connect an Arduino to your Twitch channel.<br />
<br />
After playing around for a while I came up with a LCD Bench Display that allows viewers to send messages during the stream. As a bonus, it plays some preset messages when it's not in use. Free advertising! So in this episode I'll show you how to build your own.<br />

But, I have been receiving so many requests, suggestions, and videos from people who have been inspired by this project - I think it deserves a little more attention.<br />
<br />
Many people have been asking for a fully self-contained, hardware version of the synth so that is what we will do! The first step is to add a 5-Pin Midi jack to the synth so it can be easily connected to older synths and sequencers.<br />

To properly understand pitch bend messages we will look at the bits and bytes of the Midi language.
