edit TECH
the XR10 is a digital drum machine based on a 8-bits CPU NEC D78C10G part of Z80 Zilog processor which handles up to 8 voices polyphony.

16 bits The sound is generated by internal PCM samples stored in an internal ROM wavetable, each PCM samples can be also backward, pitch-tuned at 2 octaves range and finally located in the stereo L/R panning position.



edit
WAVETABLE the XR ROM contains 64 PCM samples recorded at 16 bits resolution.
Most of the samples are old school big drums, acoustic gated toms but also electro percussions in a perfect Kraftwerk-like style.

xr10 pcm SOUND LIST: bass drums (x10), snares (x10), rimshots (x2), hihats (x3), toms (x12), crash (x2), ride cymbal (x2), claps, finger snap, conga (x4), vibraslap, guiros (x2), cabasa, tambourine, triangle (x2), cowbell, claves, timbales (x2), agogo (x2) , slap bass and a FX ochestral hit.

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.

ENVELOPE each assigned sample have 1 single EG that features:

decay2 - 1 segment DECAY

- 1 time SUSTAIN (31 levels each)

LFO section offers a single modulator SWEEP for the pitch:

the XR10 modulator LFO Parameters:

- frequency rate

- depth modulation

- polarity inversion

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.

recording xr10 Note entries system works in 2 different modes:
A- realtime at 96 ppqn resolution
B- simple step entries.

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

sync 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?).

PAD REPAIR: Cleaning with alcohol or various stuff will do nothing and can worsen situation for sure, best solution is electro conductive solution - Click to enlarge PIC -

XR-10 circuit bent: like many cheap romplers, the XR is frequently modded with circuit bending process on the ROM wavetable - usually recommanded for people who enjoy glitch and weird digital noises
