Legends Never Die
The latest in the SP-12™ family, the Rossum SP-1200® is an authentic reissue of the iconic classic SP-1200 sampling percussion system. Building on the engineering of 2020’s 35th Anniversary SP-1200 Renovation, including study and analysis of many vintage units using modern technology not available during SP-1200’s original production run, the team determined that virtually all original components ought to be used in order to deliver the sound at the very highest standard of precision. E-mu Systems co-founder and original SP-12 and SP-1200 designer Dave Rossum has duplicated the original analog and digital electronics of the landmark 12-bit drum machine sampler as closely as is possible thirty-five years after its debut. Throughout the process of creating the SP-1200 reissue, Dave was delighted that with very few exceptions, authentic components exactly the same as those found in the vintage classic instrument could be used throughout and took great care to maintain the classic SP-12 and SP-1200 circuit board layouts. Inside and out, SP-1200 is faithful to the original operation and preserves the coveted, authentic sound and character of the classic vintage instrument. Through this labor of love, Dave was able to create an instrument that should sound exactly the same even to the most discerning ears.
Changes and enhancements were made where they were compatible with the original design, without compromising the classic vintage sound. Sampling memory has been expanded to the maximum capability of the original sound engine. An all-new memory card storage solution with new functions seamlessly integrated into the operating system allows musicians to conveniently save, rename, and delete files and folders, and supports importing vintage SP-1200 disk images packaged in the popular .HFE format. Also included in every box, a 3.5” “floppy” disk 💾 containing modified software for original vintage SP-1200 units adds a new Set-up Special function allowing users to transfer all sounds and sequences from an original SP-1200 to the Rossum SP-1200 reissue over a standard MIDI cable. Whether using 3.5” disks or the popular floppy drive emulator modification, users of classic SP-1200 units are able to recall and remix their work on the SP-1200 reissue.
On the rear panel of the unit, users will find new dedicated jacks for filtered and unfiltered channel outputs as well as a new sample input monitor feature. Four sliders allow users to tune the initial cutoff frequency and the resonance of the SSI2144 analog dynamic filters on channels 1 and 2 by reaching just over the edge of the front panel, which remains cool to the touch thanks to the reissue's included new power supply with locking, XLR-style connector. Built to last with high-lifetime controls and a new, steel and aluminum case in the classic original shape, SP-1200 preserves the original sound for years to come.
12 Bit Bliss
SP-1200 maintains exactly the same 12-bit linear data format and 26.04 kHz sampling rate as all vintage SP-12 and SP-1200 units.
The unmistakable character of SP-1200’s authentic, original pitch shifting and its audible aliasing and imaging artifacts are preserved identically.
A highly requested feature, users can now monitor the input to sampling (the output of the SP-1200’s input filter and amplifier) at the mix output, or can be switched out of the mix output by plugging a cable into its new dedicated monitor output jack, just like SP-1200’s individual channel outputs removes them from the mix output.
Original SP-12 units featured unfiltered outputs from channels 7 and 8 only, while vintage SP-1200 featured ¼” TRS jacks with the unfiltered signal on the tip and the filtered signal on the ring of the output jacks on channels 1-6. Some users preferred to plug in mono unbalanced (TS) cables “halfway” to record the filtered channel outputs from SP-1200 units. The SP-1200 reissue instead features dedicated TRS jacks for balanced audio output on dedicated jacks for each of the filtered and unfiltered outputs as well as the mix output. Connecting a mono unbalanced (TS) duplicates the original SP-1200 output, with the original output impedance. In keeping with the spirit of preserving the classic vintage sound and keeping the same board layouts on the inside the unit, the SP-1200 reissue is designed so that musicians can plug the same cable into the same jack for the same sound.
Sound Construction
A continuation of Dave’s fifty-year tradition of instruments made to last, the Rossum SP-1200 reissue is expertly engineered by its original designer for decades of reliability and is built locally in the United States. Assembling and testing the instruments in close proximity to Rossum’s California headquarters allows for SP-1200’s sonic character to be delivered according to the most exacting quality standards.
The iconic original lines and shape of the classic SP-1200’s structural foam plastic housing are closely recreated with finely-textured, black powder-coated steel panels joined with elegant bead-blasted, anodized aluminum black side/end caps in the reissue. The instantly-recognizable SP-1200 panel legends are reproduced across the top and rear steel panels. Experienced users of SP-12 and SP-1200 machines will enjoy flexing their muscle memory as the placement and spacing of all original controls have been maintained exactly in the reissue.
SP-1200’s eight slide potentiometers central to the instrument are highly reliable components selected by original designer Dave Rossum for their superior feel and cycles rating and are fitted with black slider knobs with white indicators matching the factory-original look and feel. SP-1200’s three rotary potentiometers, each equipped with knurled black anodized aluminum knobs with white indicators installed on their aluminum shafts, are also excellent-feeling, long-life parts.
Rather than the fluorescent-illuminated backlight included with the first original SP-12 units, the classic 2-line, 16-character display is backlit using RGB LEDs inspired by the LED-lit backlight displays equipped in later SP-1200 units. A new Set-up Special Function (#26) integrated into the Rossum SP-1200 reissue’s operating system allows users to adjust the brightness and color of the backlight to customize their drum machine to suit any studio or performance.
SP-1200’s black play buttons use custom replica button caps and ultra-durable, low-resistance switches chosen for their ideal travel and rated to keep their same great feel for many years of performances. Dynamics can be performed using exactly the same classic technology invented specifically for SP-12 in 1984, and is faithfully maintained in the reissue. As with all SP-12 instruments, the dynamics can be optionally disabled (Set-up 14) and Multi-Level mode is featured, allowing any dynamics to be performed with a lighter touch.
Memory Bank
SP-1200’s all-new memory card storage solution is integrated seamlessly into SP-1200’s operating system. When the Disk module is activated, users can choose files and folders from the memory card using the arrow keys and the LCD. The Disk module functions for formatting and copying software to magnetic media have been replaced with Save All As / Rename. For the first time, musicians can save SP-1200 sounds and sequences in one step and delete and rename files and folders using its built-in display. Importing vintage SP-1200 disk images packaged in the popular .HFE format works frictionlessly, just like regular loading. A 3.5” disk 💾 containing modified software for original vintage SP-1200 units adds a new Set-up Special function allowing users to transfer all sounds and sequences from an original SP-1200 to the Rossum SP-1200 Reissue over a standard MIDI cable. Whether using 3.5” disks or the popular floppy drive emulator modification, users of classic SP-1200 units are able to recall and remix their work on the SP-1200 Reissue.
Double Time
For the first time, all Rossum SP-1200 reissue units feature 20 seconds sampling time.
Designed by Dave Rossum in 1984, the original sound engine at the heart of SP-12 and SP-1200 could accomodate up to 20 seconds sampling time, but 20th-century prices of the random-access memory (RAM) proved cost-prohibitive, preventing more memory from being integrated during the original production run.
Vintage SP-1200 users can transfer their work using the new special function on the included software floppy disk or import their .HFE disk images right from the memory card. Of course, even compositions that used the full 10 seconds available from a vintage unit can be revised and remixed with an additional 10 seconds of sampling time.
One of the unobtainable parts featured in the original SP-1200 is the SSM2044 analog filter, a classic integrated circuit also designed by Dave Rossum in the early 80s based on classic improved ladder filter topology. In partnership with Sound Semiconductor, Inc, Dave has designed the SSI2144 IC which reprises the same analog circuit using contemporary IC processing and packaging, preserving its unique character.
Four sliders allow users to tune the initial cutoff frequency and the resonance of the SSI2144 analog dynamic filters on channels 1 and 2 by reaching just over the edge of the front panel. While the original SP-1200 required trim pots, the sliders allow musicians to customize the instrument to fit their style or production. As an analog control, users can choose to either set and leave their dynamic filters’ initial cutoff frequency and resonance settings, or to move them in real time to add dimension to a performance.
The SP-1200 reissue features a new included power brick with a locking, XLR-style connector. The redesigned power supply and newly-constructed, four-layer circuit boards lower the noise floor and avoid undesirable hums without compromising the unique artifacts and dynamics characteristic of the SP-12 series of instruments. The rear panel runs cool to the touch, and no vents are necessary in the rear panel.
Over 35 years in the making, the team at Rossum cannot wait to hear what musicians create on new SP-1200 instruments.

FAQ
Overview
What is the Rossum SP-1200?
The Rossum SP-1200 is an authentic reissue of the E-mu SP-1200, the 12-bit sampling drum machine that defined golden-age hip-hop. It was designed by Dave Rossum, the E-mu Systems co-founder who created the original SP-12 and SP-1200. The reissue reproduces the original analog and digital electronics using virtually all original-spec components. It builds on the 2020 35th Anniversary Renovation, for which the team studied vintage units with modern analysis tools to maximize authenticity. Standard production ran from 2021 to 2025.
What's different or improved versus the original E-mu SP-1200?
The Rossum SP-1200 duplicates the original's analog and digital electronics and adds a set of modern conveniences. It keeps the same 12-bit / 26.04 kHz sound character while updating storage, memory and I/O. The main additions over the original are:
- 20 seconds of sampling time, double the original 10
- SD card storage in place of 3.5″ floppy disks
- dedicated filtered and unfiltered channel outputs
- a sample input monitor output
- an RGB-backlit display
What is the SP-1200 40th Anniversary Edition?
The SP-1200 40th Anniversary Edition is the final SP-1200 reissue production run, limited to 100 units worldwide. It commemorates the 40th anniversary of the SP-12 (1985), the first instrument in the SP family. The core electronics, sound engine and features match the standard SP-1200.

Is the 40th Anniversary Edition really the last production of the SP-1200 reissue?
Yes. The 40th Anniversary Edition is the final SP-1200 run, due to the unavailability of required parts, especially the discontinued Z80 CPU. Dave Rossum has expressed interest in future drum machine designs.
What is the SP-1200 E-A-SKI Special Edition?
The SP-1200 E-A-SKI Special Edition is a limited SP-1200 reissue created with multi-platinum producer E-A-SKI. It was limited to 50 units worldwide. It has a red and black colorway, exclusive sound content and a signed certificate of authenticity. The instrument itself is the standard SP-1200.
What is the SP-1200 35th Anniversary Renovation?
The SP-1200 35th Anniversary Renovation (2020) was the first Rossum SP-1200 reissue, a very limited initial run. It marked the 35th anniversary of the SP-12 (1985), the first instrument in the SP family. The engineering effort behind it, studying and analyzing vintage units with modern tools, became the basis for all later SP-1200 production.
Editions & Pricing
Will Rossum ever make any more SP-1200 Reissue units?
No. The SP-1200 reissue cannot be produced any longer because key parts are no longer available, in particular the discontinued Zilog Z80 CPU. The 40th Anniversary Edition was the final production run. Dave Rossum has expressed interest in future drum machine designs as new instruments rather than more reissue units.
How much does (or did) the SP-1200 cost?
The standard SP-1200 was $3,999. The 40th Anniversary Edition is $4,999. The 35th Anniversary Renovation from 2020 was priced $7,500.
Sound & Authenticity
Does the Rossum SP-1200 Reissue sound exactly like an original E-mu SP-1200?
Yes. The Rossum SP-1200 uses the same 12-bit linear data format and 26.04 kHz sampling rate as every vintage SP-12 and SP-1200. It runs the same Z-80 processor and memory map. It uses authentic components wherever available. The discontinued SSM2044 is replaced by the SSI2144, both designed by Dave Rossum on the same improved ladder topology.
Was the original pitch-shifting algorithm faithfully replicated?
Yes. The Rossum SP-1200 reproduces the complete original SP-1200 sound engine. It uses the same 12-bit linear data format and 26.04 kHz sampling rate as every vintage SP-12 and SP-1200, running on original-spec components in the classic board layout. Its pitch-shifting behaves like a vintage unit, artifacts and all.
What analog filters does the SP-1200 use, and why the SSI2144 chip?
The SP-1200 uses SSI2144 analog filter chips to recreate the original's filter sound. The original SP-1200 used SSM2044 filter ICs designed by Dave Rossum in the early 1980s, which are no longer manufactured. Sound Semiconductor released the SSI2144 in collaboration with Dave Rossum to faithfully recreate the original analog circuit. Four sliders on the rear panel tune the initial cutoff frequency and resonance of the filters on channels 1 and 2.
Does the SSI2144 sound the same as the SSM2044?
Yes. The SSI2144 is an authentic successor to the discontinued SSM2044. Sound Semiconductor developed it with Dave Rossum, who designed the original SSM2044, to reproduce the same filter character on the same improved ladder topology.
Sampling & Memory
How much sampling time does the SP-1200 have?
The SP-1200 has 20 seconds of total sampling time, double the original's 10 seconds. The original sound engine always supported 20 seconds. In 1987 the cost of RAM held production models to 10. Rossum expanded the memory to the maximum the original engine can handle and it cannot be expanded beyond that.
How is the sampling time distributed across channels?
The 20 seconds is split into eight blocks of 2.5 seconds each. You allocate the blocks across the eight channels to fit your samples. A single sound can therefore be up to 2.5 seconds long.
Filters & Outputs
Which channels have analog filters, and why do the outputs sound different?
The eight channels carry different fixed filtering, which is why their outputs sound different:
- Channels 1-2: dynamic analog filters, adjustable via the four rear-panel sliders (cutoff and resonance per channel)
- Channels 3-4: filters at a lower fixed cutoff
- Channels 5-6: filters at a higher fixed cutoff
- Channels 7-8: no filters, raw DAC output
The rear-panel filtered and unfiltered output jacks correspond to these configurations. You can pick the exact character you want per channel. The mix output sums all eight channels and applies no filtering of its own. Channels 1-2 still arrive there with their filtered character, which is why they sound darker in the mix.
How do I adjust the rear-panel filter sliders?
The four rear-panel sliders set cutoff frequency and resonance for channels 1 and 2. As the sliders are varied toward the center of the SP-1200 unit, the cutoff frequency and resonance levels are increased.
Can I disable the channel 1-2 filter envelopes?
Yes. Pn firmware v1.02 and newer, hold the TUNE/MIX/MULTI button during power-on. The SP-1200 will boot with the channel 1-2 filter envelopes disabled. The display shows "Filter Envs Off" to confirm.
What audio outputs does the SP-1200 have?
The SP-1200 has dedicated rear-panel jacks for filtered and unfiltered channel outputs plus the standard mix output, and a dedicated sample input monitor output.
Storage & SD Card
How does storage work on the SP-1200?
The SP-1200 stores samples and sequences on an SD memory card, in place of the original SP-1200's 3.5″ floppy drive. A built-in file manager lets you save, rename and delete files and folders on the card directly from the front panel. The system also imports vintage SP-1200 disk images in the common .HFE format.
How do I create folders on the SD card?
Use Set-up Special Function 27 to create folders directly on the SP-1200. This organizes sounds and sequences on the card without a computer.
Can the SP-1200 read original floppy disks?
No. The reissue has no floppy drive. The SP-1200 reads .HFE-format disk images from the SD card instead.
You can connect an original SP-1200 with a MIDI cable and use the new Special Function (26) of the included Transfer OS Disk to transfer the contents of a floppy from an original SP-1200 to a reissue.
My SD card isn't recognized or shows "no card." What do I do?
Work through these steps in order before assuming a fault:
- Toggle the SD card's lock switch and reinsert the card.
- Format the card as FAT32.
- Insert the card with the unit powered off, then power on.
- Avoid hot-swapping cards while the unit is running.
If the card still isn't recognized after this, contact support.
MIDI & Integration
Can I use the SP-1200 with an external MIDI keyboard, sequencer, DAW?
Yes. The SP-1200 has standard 5-pin MIDI In, MIDI Out, and MIDI Thru ports that can be used to connect it with other instruments. You can trigger samples from an external keyboard, use the SP-1200 as a sound module, or sequence it from a DAW or hardware sequencer. Pease see the original SP-1200 owner's manual for the note map.
Can I transfer sounds and sequences from an original SP-1200?
Yes. Every Rossum SP-1200 ships with a 3.5″ floppy disk of modified software for original vintage units. That floppy adds a new Set-up Special Function (26) to the original vintage unit, which transfers all its sounds and sequences to the reissue over a standard MIDI cable. It works with both original floppy drives and floppy-emulator modifications. You can also import .HFE images directly on the SD card.
Can I transfer samples into the SP-1200 via MIDI SDS?
Yes, you can send sounds via MIDI Sample Dump Standard (SDS). Create a blank sample first, then send the audio to it as 12-bit.
How does MIDI velocity work with the SP-1200?
The SP-1200 responds to MIDI velocity on incoming note messages.
When Dynamic Buttons is disabled (Set-up 14), the buttons always trigger at maximum velocity.
Connectivity
How do I connect turntables or stereo sources to the SP-1200's mono input?
Sum a stereo source to mono, or choose one side of the recording to sample into the SP-1200's sample input. A turntable also needs a phono preamp first to amplify and equalize the music for playback.
Operation
How do I stop a sound from playing during a performance, like a choke group?
To stop a sound that's still ringing out, trigger another sound assigned to the same channel. Multiple sounds may be assigned to one channel, and only one of them may play at a time. Triggering one will cut off any others playing. As a workaround, some users incorporate a blank or silent sound assigned to the same channel and trigger it to cut off the sound.
What gain setting should I use for the sample input?
Use the lowest gain that still gives a healthy level on the VU meter. The sample input offers up to +40 dB of gain. Start low and raise the gain control and until the level reads well without clipping.
Hardware & Display
Can the display backlight color be changed on the SP-1200 Reissue?
The SP-1200 uses a 2-line, 16-character display like the original, now backlit with RGB LEDs.
Use Set-up Special Function 26 to adjust the brightness and color to suit your studio or performance environment.
Genres
Is the SP-1200 good for genres beyond hip hop?
The SP-1200 works for any genre. The 12-bit / 26.04 kHz sound, the 2.5-second maximum per sample and the 240 BPM tempo ceiling all shape it toward that workflow. Beyond hip-hop, house, techno, and electronic producers have long used the SP-1200 for its punchy 12-bit sound and fast hands-on workflow.
Firmware & Updates
How do I update the SP-1200's firmware?
Update Main firmware from an SD card. Insert the card with the firmware file and follow the on-screen prompts. Get the current file from Rossum (download: v1.04). The separate EEPROM update, for the filter-envelope-disable feature, follows its own procedure on the Rossum documentation page.
Troubleshooting
What does the error message "Read Error 43" mean?
Main firmware v1.01 addressed the issue causing Read Error 43 messages. Update to the current v1.04 (download: v1.04) to resolve it.
Hardware & Repairs
What should I do if my SP-1200 will not power back on?
Please contact support for troubleshooting or to arrange repair. Please include your serial number, shipping information, and a description or video of the problem.
