Roland CR-78 with Roland WS-1 Write Switch

“For sale is a vintage Roland CR-78 with original manual and a Roland WS-1 write switch with original box and manual. The drum machine and the write switch are in excellent condition, both inside and out.

Externally, this CR-78 is extremely clean with only very minor wear marks, worthy of the keenest collector. The manual does have a couple spots on it, which is to be expected of a 40-year-old document. The WS-1 write switch is in immaculate condition and works very well; its manual is still tethered to the cables and the $61 price tag still stuck to its box!

Now for the fun part: This drum machine has a new lithium battery and a modified charging circuit, as well as a completely new set of high quality electrolytic capacitors. The CR-78 is known in the tech community for leaky Ni-Cad batteries and leaky Matsushita purple capacitors. The nickel cadmium battery can leak its potassium hydroxide electrolyte and wreak havoc on an unsuspecting CR-78 (and other synths from the 80s); it should ALWAYS be replaced. In addition, purple Matsushita (Panasonic) capacitors from this time period are “change-on-sight” in my shop as I have never encountered a synthesizer with these installed and NOT found at least one leaking its electrolyte and eating away at the PCB trace (typically, 90-100% of these purple capacitors are leaking in a piece of gear of this vintage). That being said, I found zero corrosion from any of the leaking Matsushita capacitors in this CR-78, and the battery only had a wet band around its middle. Given another year or two, the internals of this unit would have gone from pristine to near unsalvageable.

 Lastly, this unit has two new voltage regulators as an added precaution, delivering 5 and 15 wonderful, beautiful volts of direct current.” Click here to visit listing on eBay

“This CR-78 needs some tlc. Sometimes this drum machine operates fine, but most the the time the tempo is faster than it should be. As far as I can tell all voices work sliders and buttons work even the tango foxtrot with its missing button cap. You can also see the power cord has some cosmetic damage but works fine. This is still a nice machine I’m sure if you get this serviced and recapped you will have a healthy CR-78. Due to this items age this drum machine is being sold as is.” Click here to search for synths on eBay

“Roland CR-78 Vintage Drum Machine. Shipped with USPS Parcel Select Ground.It’s in fair condition both physically and working order. It works well save for an issue with the program section. It has to be in the memory position to play and, at this time cannot be canceled. If you know these sought after machines you’ll probably know how to fix that issue. Speed, volume, balance, intro, all the beats, instrument cancel all work fine. I’ve stored it for decades and only recently re-discovered it in a box. These things can go for big bucks but since it needs some TLC, I’ll let the highest bidder decide what this ones worth. ”

“Cosmetically- Nothing is ever mint in my opinion, but this one comes close. The outer case wasn’t in the best condition so I had a new replica made (walnut). Also, the rear jacks nuts have been polished. Please check out the photos.

Internally- All potentiometers, sliders, switches, and jacks were cleaned. The sliders were re-lubricated, the power supply was re-capped, the switch and slider dust felts have been replaced, it has a new power cord, and it has a new battery.” Click here to search for synths on eBay

“Roland CR-78 With Footswitch and SyncBox in very good condition! It works perfectly! I hate that I have to sell it, but things have taken a turn:(

The main function of the footswitch is start-stop, but you can use it to program your own rhythms. It’s not as easy as with the WS-1, but it’s definitely more cost-effective.

The SyncBox will allow you to sync the CR-78 to MIDI!! Kind of a must in my estimation. Very simple to get going.” Click here to search for synths on eBay

“I am selling my Roland CR-78 CompuRhythm only because I got a TR-808. This drum machine is awesome. It does the late 70s early industrial Throbbing Gristle thing very well. I don’t have the attachment to program beats but I did this by connecting it to a step sequencer with individual gate control for each step. The machine works just as it should.”

Roland CR-78

“Price is reflective of excellent working condition and money invested in service by LA Synth Co (recommended by Roland tech support for servicing vintage gear). I do hear the most minimal of “scratchiness” in the sliders, but it’s nothing a squirt of Deoxit couldn’t handle and the sliders themselves are very smooth. Buttons, switches, and LEDs are all operational. Case shows less than typical wear for a unit of this age – some slight gaps at the mitered edges but this is normal from my observations of other units and the case itself is intact and structurally strong.

Service performed by LA Synth Co –
~ Completely recapped the unit
~ Replaced the 5101 ICs and installed sockets so they can be easily user replaced in the future if necessary
~ Removed the battery and replaced it with one that is mounted off the circuit board and removable if stored for long periods of inactivity (note – this unit NEVER had battery damage and the original battery was still functioning properly upon replacement).” Click here to search for synths on eBay

Roland CR-78 Project Machine

“Here is my Roland CR78 which is in beautiful condition considering how old it is now.

This one has a midi kit fitted and is a rarity to find anywhere.

The Midi works like this

1. Clock (switch left): The CR-78 disables the internal tempo clock and can only be driven via a MIDI timing clock (MTC). This setting is to be used if you want to sync the pre-programmed sound or the local memory to the MIDI clock. It won’t accept any note on/off messages and the voices will not trigger externally.

2. Norm (switch centre): The CR-78 acts like it has no MIDI interface installed an will not accept any kind of MIDI message. The LED on the front goes green and internal tempo clock is selected.

3. Note (switch right): This is the main one you will be using in the studio. The internal tempo clock is disabled, clocking is done via MTC and note on/off messages will trigger the voices. You cannot start the clock from the front panel! At present the kit is tuned into channel 10 by default.

This is the 220-240V UK / EUROPEAN VERSION.

However there are some faults.Please read on.

Usually the unit works perfect and everything works as it should but every so often the bass drum,snare,cowbell fail to work.All the other sounds work fine.This could be a loose connection or something else inside the unit thats causing this fault.All the presets work perfectly and all sliders and buttons working.
However all the sounds work in Midi mode when hooked up as a sound module to your DAW.

I dont have the time to have this looked at or do it myself so it will need a good servicing by a qualified technician/synth doctor.” Click here to search for synths on eBay

Roland CR-78 with Future Retro Swynx

“Recently serviced with a new old stock faceplate installed, cleaned and new battery lithium installed for saving tracks on the programmer.

This auction also includes the awesome Future Retro SWYNX box that also you to swing the preset loops and also acts as a pattern programmer.

Last but not least this CR-78 has been modded with a knob on the back to adjust the bass drum decay, giving you a variable sound from a stubby kick shorter than the regular cr-78 bass drum all the way to a booming 808 like kick.

The wooden box itself has some dings and corner wear which is to be expected of a 40 year old machine. This could easily be replaced with any wood of your choosing in the future.” Click here to search for synths on eBay
