The two new and free libraries Magical Musical Thing and Electric Bell Toy Piano from decent samples can be used with the free decent sampler which can be downloaded here !
Magical Musical Thing :
The raw analog waveforms of a vintage Magical Musical Thing children’s synthesizer.
The Magical Musical Thing was produced by Mattel, and invented by Franklin Eventoff, inventor of the Force-Sensing Resistor. Franklin now runs a company called Sensitronics that produces sensors. The oscillator contained within the MMT is based on a 4049 CMOS hex inverter chip.
Electric Bell Toy Piano
The charming bell sounds of a Japanese children’s toy from the fifties. The instrument was produced by Nomura (T. N.), a large manufacturer of tin-plated electronic toys. Although the item described itself as an “electric vibraphone,” it bears no resemblance to that instrument, and instead features an array of bells which are struck by a spindle.
