In the effects processor, I used the DReverb VST plugin I developed, which, with minor C++ code edits, is adapted to the microcontroller, as well as the Shimmer effect, which gives a more harmonic-rich sound.
The mechanical vibrations of the kalimba body are converted by a piezoelectric pickup and amplified by a JFET based cascade to a level sufficient for the microcontroller to operate.
Thanks! I ported this plugin to Daisy Seed a couple of months ago, and used it in this noisebox. However, not all plug-ins can be ported, as the computing power of the microcontroller is not enough to implement some projects. Although I’m thinking of trying to use several microcontrollers by connecting their audio inputs and outputs in series.
To implement the effect that I used in kalimba, the same source code was used as for the VasVas noisbox. Only I didn’t connect the “Size” potentiometer, the “Freeze” button, and the LEDs.
