Roland • JX-305 GrooveSynth

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.
That's pretty much all I've listened since 90's and this thing sounds like none of that (pre-1998 music). What brought me to this was the JX- name.
I don't have it but just listen to the filters in the demo. Wouldn't pay $25 for it. Room space is more valuable than that.
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.
By the time it came out the patterns were sort of dated.
