INTERFACE  All edit with single parameter with limited display. One of most irritating function of the machine is the MEMORY PROTECT which is always turns back to ON when switching off the drum machine - no to mention the lack of backlit display.

LFO / EG 

LFo modulator

LFO

section offers a single modulator SWEEP for the pitch with following controls:
- frequency rate
- depth modulation
- polarity inversion.

Envelope

ENVELOPE

each assigned sample have 1 single EG that features:
- 1 segment DECAY
- 1 time SUSTAIN (31 levels each)

Sequencer

SEQUENCER  The maximum global resolution is fixed to 1/96 and offers 8 different level of quantisation (or humanize) from 1/4 to 1/48 plus a classic array of traditional edit functions like copy, insert or repeats. Created sequences and songs can be data dumped to Midi exclusives protocol.

A basic pattern is programmed with 4 sub-levels (FILL-INS, INTRO, ENDING and BREAKS) that can be played back with dedicated function buttons.

Note entries system works in 2 different modes:
A- realtime at 96 ppqn resolution  
B- simple step entries.  

MIDI sound kits can be triggered using Midi interface, however implementation is rather basic and offers only a control on velocity sytem.

SYNC internal tempo range 40-296 BPM or XR can be slaved to external Midi clock, altough some sync issues have been reported (maybe depends on the OS?).

MEMORY:
- 300 notes per pattern
- 20 songs
- 450 presets patterns (LIST)
- 50 styles with: 3 variations, 3 fill-ins + break +1 intro + 1 ending.

Memory battery replacement, a standard soldered Cr2032 3V on the mainboard.

MAINTENANCE  quite reliable but pads trouble: graphite contact just goes dying after many pressures and years.
<- PAD REPAIR: Cleaning with alcohol or various stuff will do nothing and can worsen situation for sure, best solution is electro conductive solution
