The tabulaRasa is a digital wavetable oscillator with voltage control of frequency, waveform selection, and the amount of interpolation between waveforms. The tabulaRasa consists of two components: a hardware synthesis module which can integrate into a modular synth system, and a software application which allows the user to create their own custom waveforms. These waveforms are then transferred from the computer to the tabulaRasa module through a standard SD card slot.
