"This a Rare Analog Drum Synthesizer with the following description:

There are several notable new features on the XBASE 888:

The kick drum and the tom toms now each have an adjustable pitch envelope and sound even phatter than before! The analog noise parameter of the snare and hi hat can be “metal-ized” to create sounds extremely similar to vintage drum machines and is fully adjustable!

And, because it has no X-Filter, the XBASE 888 is more affordable than the 999. But it still has an unbeatable sound, this little beauty!

· 9 Instruments

Bass Drum, Snare Drum, Lo Tom, Hi Tom, Hi Hat, Clap, Rim, Crash and Ride. All instruments are polyphonically playable and have individual outs. The bass drum, snare drum, lo tom and high tom are true analog circuits, and for the remainder of the sounds, the XBASE 888 uses short 8-bit samples, each routed through an analog envelope. The sample flash ROM contains 31 samples per instrument, so there's a total of 186 samples (The Hi Hat section contains 2 separate samples for Closed and Open HH).

· Real analog sound production

The BD, SD, LT and HT use true analog circuits with full digital control, which allows the storage of presets and full midi control of all parameters. To keep the analog circuitry as pristine as possible, all D/A converters are specially designed for and integrated into the circuits with proven XBASE/AirBase technology.

· 16 knobs

Sound editing is made by continuous rotary encoders for every analog parameter, allowing you to edit the sounds without jumps or awkward turning situations. Close to each knob there is a 3-color LED indicating which parameters are editable for the selected instrument.

· Improved kick drum

The most famous sound of the original XBase-09 was clearly the kick drum. Now, on the XBASE 888, that famed kick drum circuit adds an adjustable pitch envelope. With this added feature, the decay time constant is changed, and you can create 808-like slow pitch decays. Additionally, the new compression parameter is useful to morph between a 909-style ultra compressed envelope or an 808-ish exponential curve.

· Analog tom toms

The XBASE 888 also offers the extremely phat, punchy and widely editable analog tom toms as originally included on the AirBase99/JaZBase03/XBASE 999. However, now they each employ an adjustable pitch envelope.

· Internal step sequencer

The XBASE 888 also features the renowned JoMoX step sequencer, with some notable improvements: all patterns are A/B patterns, and you can now choose between having two alternating 16 step patterns or one 32 step pattern. The sequencer utilizes 3-color LEDs to indicate the individual step edit modes even better and more intuitively. The micro shuffle can now be edited for each instrument individually. Bank select now has its own switch. 4 banks with each 16 A/B patterns are now available, resulting in 128 actual 16 step patterns.

· Stereo mix with pan control

All instruments except for the kick drum can be panned in the stereo bus. If a cable is inserted into any individual output, the corresponding sound is removed from the stereo bus.

· External midi tracks

As on the XBASE 999, there are 4 tracks with which to control external devices by programmable midi notes, and the knobs on the XBASE can also send midi cc messages to your external devices.

· 2 LFOs

Of course the XBASE 888 retains two phat LFOs which can be clocked to tempo or run freely and which can be routed to any destination.

· Hi Hat filter

The Hi Hat section contains a great sounding analog band pass filter with independent lowpass, highpass and resonance controls. In addition to the 8-bit HH samples, analog noise can be the sound source as well.

New: instead of pure white noise you can now create a wide variety of “metal-ized” noise signals, tweakable by 2 parameters, which can be the source for the snare or hi hat.

· Large alphanumeric LCD display

For a more convenient and clear operation the XBASE 888 has a big alphanumerical LCD display with 2x24 characters. Kits can be named and the analog step sequencer has a bar display."
