The JX-305 is an awesome synth for electronic & techno musicians! It's like an MC-505 groovebox in a keyboard. All of the MC-505's excellent dance-oriented sounds are included, as well as 4MB more! Combining keyboard style patch synthesis & performance with Groove Approved dance patterns, sequences and phrases the JX-305 is a real dance production studio with 768 dance patterns, 256 User, 640 patches and 28 drum kits.

Perfect for live use with its massive 64 voices of polyphony, you can jam along with it while it's instantly playing a great techno/dance groove! Then grab anyone of the 9 real-time control knobs to start tweaking the filter, envelope, tempo, arpeggiator or LFO. All real-time edits, pattern changes, tweaks and keyboard playing can be recorded into its 8-track sequencer - a robust sequencer with quantizing and edit capabilities! If your bag is dance, trance and rave then this Groovesynth may be all you need! It has been used by Astral.

This was one of my greatest synths! I felt in love with it a soon as I saw it the first time. An absolutely cool device! Designers of the 90es seem to have been the best. Nowadays Synthesizers are mostly plastic crap. This 305 was the grooviest ever :-)

Advice to the user below: Unplug the keyboard and use a external balanced master keyboard. Knobs and Controllers will work though.

@adam, sorry about the delay. I don't check this page much if you want to contact me through my website, message me via www.ownGR.com. I hope that this is an appropriate post as I am simply trying to help you fix your synth.

I brought the JX-305 as my first synth 2 years ago 2nd hand for £100. It's amazing! It's not only fun but it teaches a beginner all about many different things involved in electronic music. Sequencing, sampling & how to built tracks. The sounds on it have endless capability. The drum sets & orchestra samples are great. When you learn how to program it, it ends up being as useful as a workstation & makes you want to learn. Not a single problem mechanically so far. It's built like a tank. I've owned & tried a few synths & the JX-305 will never leave me. It's a keeper & endless fun bargain.
