Roland JX-305 Image

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.

Great keyboard the JX305,if you like the MC505 &'s the MC505 sort of keyboard version.Really good for dance,& so is the CS6x too which i own also.The plg boards add a wealth of things to the CS6x...i only with they'd produce more like imagine the nord lard sounds or anyother synth you can think of under the CS6x engine.

I was excited to get hold of one of these after my great experience with the SH32. I guess I was hoping for more of the same but with faster processing, but I was left cold. Side by side, the SH32 is punchier and has a great deal more clarity. Most of the same waveforms were used so it is easy to compare, but it sounds like the JX is playing them back at a lower rate (?)

4 osc per sound is great, until you realize that this will cause the dreaded MIDI jitter as the CPU dies on it's [beep] trying to process everything. Awkward and unfriendly to program, I just cannot recommend this.

Very underrated machine!!! I think it was the 'Groove' label... anyway, the JX-305 is a great composing tool, easy to use, usable drums kits, nice leads, pads... it has the flexibility of a true synth (if you are into sound creation), and for a good price!!! Back in the day, was very popular in Europe and Latin America. It is also a great controller with velocity, aftertouch and midi setups dedicated to knobs.
M83 used it on their first couple of albums, especially the patch "Film octaves". Jean Michel Jarre and Trent Reznor used it too. One notable user is also the keyboardist of the band Effectus Tralali, who still performs with one.This blue synth is destined to be a classic! Get one of 'em while you can!

i just picked one of these up and wow, this is one flexible machine for any 90's trance, D&B, hip hop, or minimal to modern day electronic music. I wish it had a high pass filter but no biggie. And if you like the MC-505 or MC-303 then you wont want anything more then this.
