VOICE 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. The sound is generated by internal PCM samples stored in an internal ROM wavetable and 12 parameters:
Sound Volume (0-31), Sound Tuning (+25/-26 in 100-cent steps), Fine Tune (+7/-8 in 6.25-cent steps), Pan (31 positions), Effect Send Volume (0-31), DCA Decay (0-31), DCA Hold (0-31), Sweep Decay (0-63), Sweep Depth (0-31), Sweep Polarity (down/up or up/down), Reverse (forward or reverse play), and Velocity Feel (on/off).
PCM 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.
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 orchestral hit.
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.
section offers a single modulator SWEEP for the pitch with following controls:
- frequency rate
- depth modulation
- polarity inversion.
each assigned sample have 1 single EG that features:
- 1 segment DECAY
- 1 time SUSTAIN (31 levels each)
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?).
- 300 notes per pattern
- 20 songs

- 50 styles with: 3 variations, 3 fill-ins + break +1 intro + 1 ending.
Memory battery replacement, a standard soldered Cr2032 3V on the mainboard.
- edit interface
- cheap built
- some great samples
- old school
