Emu Drumulator (1983)
MODEL #7000

 

The Drumulator was the first sample-based affordable drum machine based after the Linn Drum and Oberheim DMX public success.



Vintage PCM 8 bits sounds on EPROM with sequencer with a design very close to legendary sampler EMULATOR II.

edit TECH classic 8 bits Z80 ZILOG CPU manages 8 channels polyphony and each channel features a assigned samples out of 12 PCM available. NOTE: TOM channels are filtered by 2 famous chip SSM2044 (static)

cpu

The internal sample cannot be much altered but 15 quantized volume levels.

 



editWAVETABLE
the drumulator contains 12 PCM waveforms coded at 8 bits resolution stored on 4 A-B-C-D socket EPROMS (Erasable Programmable Read Only Memories) for a mere total of 64 kb.
It is possible to change the soundset by swapping the 4 EPROMS + 1 needed OS EPROM with sample offset values

drumulator tech

Internal factory sounds are: bassdrum, snare, tom (x3) clave, cowbell, claps, hihat open/closed and ride cymbal.

edit SEQUENCER
Up to to 4 tracks can be recorded at the same time with free signature and variable groove-swing processor. The patterns (segments) are recorded in real-time mode with a variable auto-correct precision quantizer: 8/.8/16/16./32/32 (triplet).

sequencer

SYNC: analog trig (at 24ppq) or RS232 / tape sync.
TIP: In order to simplify recording, the sequencer features a smart programmable audio-metronome with various time dividers.

edit EDITOR and PAD the original EMUARCHIVE (now offline) mentioned a special APPLE II GRC - Graphic Rhythm Composer - hooked to RS232 port. I never had a clue about this one after decades of searching.

editREPAIR - MODIFICATION the Drumulator is a pretty reliable Z80 machine: classic push buttons may need to be replaced and sliders too are the main issues.

drumulator midi mod

LEFT Classic and easy modification is the MIDI interface which need new OS 3.0 EPROM and a little DIY board, schematics can be found on the net.

TIP: to access Midi control on new OS, push [RUN STOP] + [EXTERNAL CLOCK]

 

 

edit OS latest is OS 3.0 EPROM needed for Midi retrofit
