Calc-U-Synth

Calc-U-Synth is an emulation of the Casio VL-Tone, the classic digital calculator/synthesizer hybrid released in the summer of 1979 and manufactured until 1984. The VL-Tone can be run in one of two main modes: calculator or synthesizer. The virtual synthesizer software is a monophonic instrument that has 5 preset sounds as well as a user programmable 6th slot called ADSR. Calc-U-Synth synthesizer plugin was created using the Reaktor Blocks framework, which means that if you own the full version of Reaktor, you can incorporate the blocks into your own creations.

Spot-On Emulation

Calc-U-Synth was designed to present the full capabilities of the VL-Tone’s programmable features in a more convenient interface, while retaining the character of the instrument. Great care was taken to measure and reproduce every aspect of the original accurately. The VL-Tone had its own built-in speaker, which was analyzed and modeled for an authentic tone. For added lo-fi realism, the key-click sounds of playing the instrument were also sampled and included. You can dial in as much, or as little as you like. The sound was then expanded using a number of effects and performance options including an arpeggiator, circuit-bending glitch controls, and a filter & delay effect module.
