GAKKEN SX-150 MARK II / MK2 ANALOGUE SYNTH, WITH MIDI-IF INTERFACE

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"The Analogue Synthesizer SX-150 MK2 is quite an advanced little synth. With multiple controllable parameters, line in and out and a four octave range, it’s an amazing piece of kit. The Analog Synthesizer SX-150 Mark II uses an electrode stylus to play tones, is battery powered and is a quality piece of kit.

Also this auction includes a MIDI-IF controller, this means you can plus the Gakken in and play this with a midi keyboard. This adds features of tune, modulation rate and glide to the Gakken and like the Gakkken is battery powered."

According to the QA in the listing, the MIDI-IF "was custom made by beatnic.jp in Japan, the model of this controller is a MIDI-IF for the Gakken SX-150 mk2."

You can see another model of the MIDI-IF for KORG's Monotron here.


They also made The Mountain synth. See the beatnic.jp channel label at the bottom of this post for more.

"A first foray into the newly expanded Telstar Attaché Synthesizer. Here I'm just trying to figure out what does what and why. The new, logic-defying, sequencer is now driving the synth modules. If I can learn how to control this thing it'll be a beast. No other sounds or effects are used here."

If you are not familiar with Gakken, it's a Japanese magazine that sometimes comes with an included gadget. There was an SX-150 and SX-150 mkII analog synths, two theremins, and a GMC4 microcomputer. A search on Gakken will bring up some videos and pics. You can find Gakken products on eBay here.
