JoMoX XBase 09

The XBase 09 is serious about emulating the Roland TR-909. Like the 909, it is an analog drum machine, and it sounds just like the 909, and more! It offers the same types of analog controls that the TR-808 and TR-909 did such as tuning, level, decay, snap, etc. However it provides more of these controls for more sounds than the originals ever did and has MIDI implementation and Patch memory making the XBase 09 a much more versatile machine than those originals.

Kick and snare are true analog, not emulation and not sampled. The Hihats, cymbal, ride, rimshot, claps and noise sounds are samples but are still quite tweakable. All your edited sounds can be stored into the 100 patches of memory. Use the built-in LFOs to modulate the Bass drum pitch, Snare Tune, Snare Snap, Snare Noise Tune, HiHat Tune or LFO 2.

The XBase 09's built-in sequencer is also more advanced yet faithful to the style of its mentors. Step or Real-Time programming just like it's done on the 909 and 808! However, on the XBase, any edits to the sounds will also be stored with the pattern or song! This really liven's up your beats and allows you freedom and control to do things not easily possible on the original beat boxes! There's also an extensive Shuffle mode. Of course the XBase 09 is also happy as a simple drum tone module, with all editable controls accessible using MIDI. The controls also send MIDI data when tweaked so you can record real-time edits into your external sequencer.

If you're looking for the TR-909 that should have been, here it is! Authentic sounds with more functionality and modern MIDI specs make this the perfect 909 for the 90's and beyond. Its only limitations are 3 voice polyphony and it's expensive. The AirBase-99 is a cheaper rack-mount alternative with added Toms.

I've had mine for a few months now, and let me just say this machine is a true pleasure to use. No bugs encountered, but then again I did install eproms with the newest OS (easily obtainable from ebay). The sounds are extremely tailorable, and although it easily does the 909 thing, you can get very near-808 sounds, and completely different sounds as well. 3-voice polyphony was a big concern at first, but has yet to be a problem. I love the option to use noise as a hi-hat. The 3-track sequencer (for external devices) is the most tedious thing about this machine. Otherwise, it's awesome.

Got mine today and damn the kick and snare sounds wonderful. love all the extra features with LFOs and x-mod. the only real downer is that the handclap and rimshot are not analogue. Kick and snare are awesome though. like the 909 but longer, snappier deeper and clickier when you want them to be. looks good on the workbench too. like a mini909

I bought one of these due to not having enough money to get a real 909. After having it only a week it crapped out on me, though I don't attribute that to JoMoX (I bought it used and the previous owner very well might have been selling it because they screwed it up). Anyways, after returning it and getting my money back I saved up and bought a real 909. My time with this, as short as it was, was a good learning experience. This machine has great sounds and editability for those sounds. I personally liked them better than the real 909, but the option of only having 3 sounds at a time on this was very limiting and for that reason alone I would take a 909 over this almost any day. I'm very interested to try the XBase 888 or 999 as I think they would be a good mix of the features I like from both this and the 909.

LOL, this thing was wild. You just have to own one for at least a little while to know what an incomplete buggy drumbox interface is like. No doubt it's sounds are cool as sh1t! The 3 note poly writen here is misleading the analog bassdrum is of course monophoric, as is the thin sounding but verry 'ticky attacky' snare voice. All the other sounds it makes, it does so using a lil One note ROMplr. Thats right only one sound at a time be it hats, rides, claps or stix. IE the stick would cut off the ride or open hat. BUT in thin quirky weakness, a strength in uniqueness appears. You get that 'Daft' sounding mono sampler sounding drum line. The other BIG downside which HAS no up, is the fact that youll be changing a parameter and the whole voice goes buggy n shifts everything around all willy nilly. NOT COOL the sequencer did the same thing on me a few times. So I sold the F out of it. LEGENDARY BASS DRUM THOUGH dont use the sequencer, lol!
