Icebreaker Audio has released the PortaSynth and Clac-U-Synth instruments for Native Instruments' Kontakt 5 platform.

PortaSynth is an emulation of a circuit-bent Yamaha PortaSound PSS130 from 1987. It also includes PortaDrums – a drum machine based on the percussion samples from the same instrument.

Calc-U-Synth is a full emulation of the Casio VL-Tone's programmable synth engine for Kontakt. It features faithful emulations of all of the VL-Tone's parameters.

Both PortaSynth and Calc-U-Synth are included in the ToyBreaker Bundle, which also includes HandySynth – a sample based emulation of a circuit bent Yamaha HandySound. Not only does this bundle save you around 25% of the total price of buying the three products separately, but as an added bonus, ToyBreaker Bundle owners also get an exclusive battery kit of drum samples taken from several toy keyboards from the 80s.

• All instrument sounds sampled chromatically at 24bit, 48kHz quality.
