This project started unexpectedly. Most of my projects started in the imagination and planning for a few weeks. In this regard, the project was right on track since I imagined this build and aspect for months while I built the other EWC projects. I wanted something portable like the EWC_Pocket but with more range and I wanted it to be self-contained instead of one that needed a full-fledged computer or a separate sound module. This one started unexpectedly because I did not intend to start any music project so quickly after the enormous Electronic Wind Chimes. Despite the ordered but informal sound, I missed having the background noise, but the bulk of the device made it a challenge to use often. Perhaps I'll hang it on the wall later.

The concept of the EWC_Handheld was a portable pseudo-random sound generator with multiple channels and minimal controls. One of the potentiometers will control the tempo. One pushbutton will prandomize the settings of the current channel such as a new instrument, pitch offset, and play frequency. The second potentiometer will adjust the velocity of the channel in question. The last button will accept the current settings and add a new prandom channel. Since this will allow fifteen unique channels, it will be more versatile than the EWC in a sense.
Another function that has been under consideration for a while was a device that allowed the user to control a switch that would generate a note when pressed and sustain so long as it was held. Each new press would stop the old sound and start a new prandom note. This was conceptualized as a single piano key, but that would be too small for a simple prototype. This mode will become active when the tempo is set to zero.
