Team Status Report for 3/15

The current most significant risks are in our PCB and our interface components. For our PCB, because of the time and cost it takes to get it made, we are unlikely to be able to fix any issues that come up after fabrication. To mitigate this, we are working to look over any possible issues that could come from voltage mismatch or positional issues, and have backup plans in case an issue still arises, including full backup perf boards already ordered and plans for smaller perf board designs that could be easily implemented along with the PCB if the issues are coming from the input or output. For the interface components, the main risk is that they do not work at all or as intended, so we will be testing all of them in prototyping over the next few weeks to ensure that they work. One major change was made to the existing design, with us getting rid of the row of buttons for pitch shift and adding their functionality to the LED buttons we are using for beat selection, with the pitch shift option on the slide switch altered to allow for this change. We did this after realizing that physical switches for the pitch shift buttons would not work if only one beat could be modified at a time, as they would allow for multiple to be turned on. The LED buttons allow us to provide visual feedback for a beat being unselected as another button is pressed. There are no major costs from this change, as it requires no additional hardware and just shifts some of the software work left to do around.
