Japanese kit-maker Gakken has just released a special special edition of the Otona No Kagaku publication focussing on music synthesizers. The issue includes an SX-150 stylus-input analog synth kit which appears to require relatively little effort in the way of assembly (a feature which may be a demerit in the eyes of some avid solderers). Have a look/listen of the device in action –

The external control source seems to hold a lot of potential – and from what can be discerned from the compressed audio, the unit seems to sound rather nice. (want want)

    That last half reminds me of old SciFi like Lost Planet.

    That’s not fair! The soldering is almost done!

    @Shady – agreed :(
    it would seem not everyone enjoys circuit assembly as much as we do.

    Man, this thing looks awesome! Awesome I tell ya!

    I’m still trying to get my hands on their theremin kit, and now I find this little beauty…

    The basic design reminds me of a Stylophone, the vintage synth that uses a stylus to connect a circuit. Although stylophones didn’t have knobs to fiddle with, their keyboard interface was actually in scale (like piano keys).

    Thank you for using my photos. This kit is easy, simple and cheap! The detailed explanatory is also attached. Then, this is the core of a first step for “MAKE”. Many people already enjoy modification.

    I have just received my Gakken Synth today, coincidentally at the same time as the man across the hall got one. Both of us built them in 5 minutes, they both sound great, however neither of the external source functions work. Any ideas??

  7. Collin Cunningham says:

    @smcg – I’ll have one on hand for testing soon. I’ll let you know if i can lend any insight.

  8. Collin Cunningham says:

    ok – I could see how the external source jack would seem unresponsive – it’s designed to respond to frequency, but requires a pretty hot signal to do so. It worked well with me benchtop function generator.

    the frequency/pitch input seems an odd choice, i was expecting a control voltage input – but that can be had by wiring to the stylus
