Roland JX-305 GrooveSynth

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.

I've mine still. As it come out I sold out all my old stuff that time. This thing really does it all. Hardly used for goa productions. Very cool. Now I am going back to use more different analogue Synths. So there's no use for it anymore.

Wonderful synth. Powerful and very funny. The only limitation was: unable to handle decent midi implementation. If you want to work like a computer, a lot of hangs and holds, frozen, etc.

I would like buy it again ( I use to have 3 different units) but being difficult to edit songs outside synth (in logic or another sequencer) it's a real pain.

Tried it and was not that impresed but god idea for groove people.
By the time it came out the patterns were sort of dated.

il JX-305 è un synth pazzesco, potentissimo, altro che juno D-G, i vari JV. Credo che chi lo possegga e vuole migliorarsi deve passare direttamente al Fantom G6. Sarebbe davvero inutile sostituire questa meravigliosa macchina anche con un Juno G.

This board is very cool. i picked it up by accident from a trade with a friend. he didnt include a manual but that didnt stop me.
first of all.. i do love the way it looks on my rack. its got plenty of buttons to navigate the menus. simple to record quick demos.
then i wanted to try the range of sounds.. as far as romplers go i am usually disapointed. i been using software for the past 5 yrs but im going to use this keyboard forever just for its bass and weird keysounds. dont knock the presets. i kinda cant this board just feels good in my setup.
