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 VOICE classic 8 bits Z80 ZILOG CPU manages 8 channels polyphony, each channel features a assigned samples out of 12 PCM available. The internal sample cannot be much altered but 15 quantized volume levels.
TECH: TOM channels are filtered by 2 famous chip SSM2044 (static) PIC

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.
Internal factory sounds are: bassdrum, snare, tom (x3) clave, cowbell, claps, hihat open/closed and ride cymbal.
TECH: It is possible to change the soundset by swapping the 4 EPROMS + 1 needed OS EPROM with sample offset values - last one should be 3.0 with Midi instructions. We have 2 alternative set we recorded right into the DEMO SECTION

edit INTERFACE a lot of combo keys: some functions are not so intuitive and need a first good read to the owner's manual. Yes reading manuals seems "vintage" now ;)

edit SEQUENCER
the patterns (segments) are recorded in real-time mode with a variable auto-correct precision quantizer: 8/.8/16/16./32/32 (triplet). Up to to 4 tracks can be recorded at the same time with free signature and variable groove-swing processor. In order to simplify this task, 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. Also a simple PAD programmer with same design with 4 trigger out.

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.
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]
