Replacement Synthesizer Key Guide and List of My Stock

Pratt-Read keyboard assemblies found their way into a lot of early units. At least the ppg 2.2,2.3, Minimoog, Sonic Six, Satellite, Micromoog, Polymoog, Minitmoog and Multimoog, Sequential Circuits Prophet 5, Prophet 10 and Pro One, ARP Odyssey, Axxe, Quadra, Omni, Pro-Soloist 2500 and 2600, Oberheim 4 voice, OB-X(a), OB-1 and OB-SX, and a few OB-8, EML 100/101, Octave Cat/Kitten, and I'm sure probably others. If anyone knows ones that are missing let me know. (I stock fresh Key Bushings!) Check for price and stock notes below Ordering Instructions. (NOTE: I see I have two styles of this in stock. One is as pictured, the other the part that drops down in front is flat instead of having sides on that part. Make sure to order the right one)

Akai AX73 keys are unweighted version of Korg DS-8/Kawai K1. Sometimes weights can be removed but it's often very difficult and you wind up breaking keys.

Akai AX80 keys are exactly like Korg Lambda except they have the piece in the middle to strike the rubber switch housing. In a pinch a Lambda type key could be adapted to suit the purpose. Check for price and stock notes below Ordering Instructions.

Akai VX600 Identical to E-mu Emulator II and very close key to Korg Poly61 but some modifications required on the hook on the black key which projects sideways too much on poly. Usually old one can be cut/retro'd from old key I'm told. Photo courtesy of Thomas Rogers

Alesis QS7 keys are very similar to Triton LE and I have modified them to work; cutting hole w/dremel for access to release lever in back. It's been a while so I'll have to get a refresher some day but for now note also that the General Music SK760 has keys of this type with the cut out for the lever catch in back, but they have a front that drops down to give a nice white smile in front. Otherwise identical I think. Maybe the Alesis had that too and I just can't recall modifying that. Anyone know?

Late Odyssey MkIII. Also fits Octave Kitten, later Axxe and SCI Pro-One. synthparts.com appears to have them in stock.

Casio CZ1000 appears to be same as ALL CZ full size including CZ-1000, CZ-3000, CZ-5000. SAVE a perhaps rare exception. SOmeone bought a CZ1000 thinking they would get keys off it. THe keys were totally different with Roland style springs! So BE SURE TO CHECK before ordering FZ keys...which appear to be modifiable to work. I had 2/2 success pulling weights out so far. Heat with hair dryer.:-). Check for price and stock notes below Ordering Instructions.

Casio FZ-1 Probably fits CZ-1 also as they are velocity sensitive. Possibly can be modified it appears to use this key for other CZ full size units by shaving the contact 'bumpers' off and replacing them with a rubber foot or something of the same thickness at the right spot to push down the contact on these non-velocity sensetive models. Check for price and stock notes below Ordering Instructions.

Crumar DS-1 See service pic in DS-1/2 page for metal part of keys. These are also used I see in the Crumar Multiman, so possibly others of that series as well. These are kind of similar to Pratt-Read but they use glue instead of a screw to hold this top on the metal.

Mirage1 These are in the Ensoniq Mirage DSK-8 (metal case) (Link to Syntaur; thanks guys for making these available!) I have the bushings for these Pratt Read variations below.

Early Ensoniq These are in the Ensoniq Mirage DSK-1 (plastic case), ESQ-1, and Crumar Bit-One I hear. Others? (Link to Syntaur)

Later Ensoniq are in the ASR-10, EPS, EPS-16 Plus, SD-1, SQ-80, TS-10, VFX, VFX-sd. These appear to be yet another rendition of the keys used in Korg CX3's and Kawai K5000. Did Fatar make 'em? (Link to Syntaur)

Early Fatar These are in the Crumar Performer to at least the Trilogy and also some Siel like the Orechestra 2/OR-400 and SCI Prelude version of the same. Note metal clip that spring hangs from that slides in from top of that back piece. Check for price and stock notes below Ordering Instructions.

Early 80's Mini Fatar These are in the Siel DK-70. Not sure what else now. Check for price and stock notes below Ordering Instructions.

Early 80's Fatar Near same as Siel DK600, DK700, DK80, Crumar Bit99 (save old keyweight and a slight plastic cut required if you adapt one of these keys), E-Mu EMAX II. Ensoniq SQ1(+)and SQ2 adaptable also. NOTE: Noticeably browner 'black' keys on DK80 than DK600. Check for price and stock notes below Ordering Instructions.

Kawai K3 Similar to Korg DSS-1 and Lambda/Delta but I don't see an exact match. Remove the weights and they work in AX80 and Lambda etc. but very difficult to do. Photo courtesy Kawai.

Kawai K5 Similar to K3 but different. Photo courtesy Kawai. They have replacements.

Kawai K5000 keys are also used in Quasimidi Raven, and possibly Cyber6. I see that the Nord Electro also uses a very similar key. and again Korg CX3 key with a different key weight area cover. photo courtesy of Ivan Schwartz See Kawai for replacements.

Early Korg keys are used in 700S, PS series, MS series and Sigma. Also see later Moog synths above. Teisco SX-400? Others? Very likely all older Korg's but haven't gotten absolute confirmation yet. Check for price and stock notes below Ordering Instructions. Also Kevin Lightener bought Fred McNiff's stock (Synthfool.com). Photo courtesy of Mattias Moller.

Korg CX3- NEW VERSION. Not aware of anything else that it fits exactly. K5000, Quasimidi Raven/Cyber6, Nord Electro and some Ensoniq are same except weight part which can often be modified with dremel tool etc. See below for pricing. Check for price and stock notes below Ordering Instructions.

Korg DS8 keys are used in Fender Chroma Polaris, Kawai K1, K1 II, K4 and K11. Also E-mu Emulator II I'm told and Akai AX73 uses unweighted version. Check for price and stock notes below Ordering Instructions.

Korg DSS-1 keys. Used also in DW8000. Check for price and stock notes below Ordering Instructions.

Late 70's Korg keys for Delta, Lambda Trident and old CX3/BX3. With minor modification these also may be used in Akai AX80 and AX80 can always be subbed in for these units. Check for price and stock notes below Ordering Instructions.

Korg Poly keys fit MonoPoly, PolySix, Poly61, Poly800, Kawai SX-210/240, and MemoryMoog, and Oberheim OB-8 (OB8) after first few I hear which still used Pratt-Read. Also later SCI are nearly identical and can be substituted in a pinch. Akai AX60 is a slight modification again of the under bumpers but compatable it appears. The DS-8 above is weighted and has a slightly shorter and narrower hook (the poly one actually sticks out sideways at the bottom causing it to interfere with certain situations I'm told). Check for price and stock notes below Ordering Instructions.

Korg X3 keys. Appears identical to Yamaha Ridged keys below. When back end cracks I've gotten by super gluing the pieces back together and searing the edges of the crack with a hot soldering iron though.

Triton LE- keys are also used in Karma, and Waldorf MicroQ I'm told. Adaptable to Ensoniq Fizmo and Ensoniq SQ2 with addition of weight. I've also used these on Alesis QS7 and Peavey DPM SI aren't much different and possibly other Peavey synths except dpm488 and C8 which are weighted of course and replacements must be gotten from Peavey on those. Check for price and stock notes below Ordering Instructions.

Kurzweil K1000 keys have a similar design to the Crumar Performer in the metal clip used to hold the spring, but as you can see a weighted key of different design in other places. The K1200pro has the SAME KEY it appears...but uses a spring that hooks into the top hole instead of the spring/clip combination of the K1000 unit. It was sprung lighter which really annoyed me since double triggers would occur in my style of play, and I adjusted the springs...all 88..to my specs! It's been my main controller ever since. No idea where to get replacements for either of these. Hate to scrap such great sounding and usually repairable instruments to get keys.

Later Moog are used in Prodigy, Source, Rogue, Liberation, MG-1 and Opus-3. These are the same as the Korg PS, MS, and Sigma below in design. Check for price and stock notes below Ordering Instructions. Also Kevin LIghtener bought Fred's stock (Synthfool.com).

Memorymoog keys are same in design as Korg Poly keys. Check for price and stock notes below Ordering Instructions.

Oberheim Matrix 6 As you can see, this is totally identical to Kawai K3 without weighting. The weights can be removed usually from those keys with ease in a pinch. Or not someone said. Possibly Kawai upgraded the glue job. One can always use them in a less used place with a shortened spring I suppose w/out pulling the weight out. Pic courtesy of Martin Weetman

Early Roland SH-1000(2nd version**), SH-1, SH-3(a), SH-5, JP-4, and probably ProMars take these. F Key #106-015 to Black key #106-023. Many early manuals only give number for the entire keyboard's they used. From those numbers (which only have suffix differences) and the fact that it is unlikely Roland would have introduced a new key for such similar products, I'd guess all the early ones take the same keys**. However the 2000 had after touch so, who knows! (** The earliest SH-1000's had a slightly different key design but the white's are compatable it appears but the blacks are not! ALso there were different springs for the black keys and all springs are the same on the later SH-1000's. ) Check for price and stock notes below Ordering Instructions.

Roland early 80's are in SH-101, Jupiter-8 JUNO-60, JUNO-6 and VP-330. Very minor difference to the keys used in Juno-106 in that 106 keys have less contact area where the 'webbing' of plastic is underneath towards the rear center. These APPEAR from drawing in manual to be IDENTICAL to the keys for JX-10 below, which are weighted. (I've tried to remove weights on the S-10 keys. Impossible on whites without a slow milling process. On blacks you can drill the lead out until it's so weak that you can remove it if you are good with a drill. SO in a pinch that's your options. ) Part #'s sequential ending on black key 106H032 Check for price and stock notes below Ordering Instructions.

Roland early-mid 80's I have confirmed that at least JUNO-106/HS-60, Jupiter 6, Alpha Juno 1, HS-10, EP-11/piano plus 11, and some JX-8P take these. (Some JX8P have keyweights. Always specify if your JX8P has weights or not. ) Part #22575140 for black key. Part #'s are always in a sequential order, like C/F key ends 136, according to service manual. Originally Juno keys it appears lack the understructure to support hitting of the second contact. So you can NOT take these keys and put them in a JX-8P without retroing them to create a flat surface extending further back underneath. At some point Roland likely began supplying only the JX-8P key for both synths. I've never tried them in the earlier yet units. But wait, it gets worse than that. A customer is requesting keys today who has a JX-8P with weighted keys! The type below should sub in fine for these though they have more understructure than needed. Check for price and stock notes below Ordering Instructions.

Roland mid-late 80's are used in D-50, JX-10 and S-10 take these. Part #22575212 for black key. Totally identical to JX-8P keys except with weights on SOME units. It appears Roland began weighting these and most I've run across so far have the weights. One person said theirs did not have them. So check before ordering. Check for price and stock notes below Ordering Instructions.

Roland Later 80's/Weighted- The U-20, JD-800, D-70, Model 660, Model 760, KR-33, KR-55, KR-500 and SK-7(P). Part #22575261 on U20 for black key. I'm informed that these are very similar to others in design except they use some horrible epoxe that melted down in certain conditions often ruining things. Check for pink/red epoxe. I've never tried to fix..but it could be some adhesive that doesn't react could cover over the problem. These also had a guide bushing issue which Roland issued an extended one to fix. Check for price and stock notes below Ordering Instructions.

Roland Later 80's /unweighted- D-5, D-20, EP-3, EP-5 is same key as above w/out weight. Check for price and stock notes below Ordering Instructions.

Roland Later 80's/unweighted- Similar to S-10 without weight. The D-10 at least uses these. Possibly same as unweighted JX-8P I've heard rumors of. Anyone know of others that were unweighted that are compatable? Obviously backwards compatable to Junos and others sometimes with slight mods underneath probably. Check for price and stock notes below Ordering Instructions.

Roland Early 90's- AT-50, AT-70, JV-80, JV-90, XP-80, EP-7, EP-9, KR-350, KR-650, PT-8, PT-1000, VK-1000, and SK8(P). These also suffered some of the bad epoxe episode. Check for the pink/red epoxe. Check for price and stock notes below Ordering Instructions.

Roland Early 90's- AT-30, AT-80, AT-90, VK-7, and SK-9 also suffered from the red epoxe syndrome. Improved epoxe in AT's with "R" suffix and VK-77. Photo anyone? I believe I have a D for sale here only. I believe these are the ones that look almost identical to the JV-30 but lack the extended front plastic 'weight cover'. Roland late unweighted- These are used in the JX-305, SK-88pro, JV50 and W-50 it appears at least. They are unweighted versions of the AT-30 etc. above I believe. Someone please confirm this for me. Process of elimination based assumption :-). I've ordered this key from Roland and have a weighted version of it here and it and the above are the only keys I've run into that I dont' have matched.

Roland E35 These are smaller keys from fatar obviously. Nearly identical to Siel DK70 except without extension to hold spring actuator. Same save slight mold alteration of no consequence to Korg i3. Check for price and stock notes below Ordering Instructions.

SCI MultiTrak- These are identical to Korg DW-6000 and are used inProphet 600 and newer Sequentials Circuits units it appears and also compatable with Korg Poly6/61. Note a slight but insignificant variation, at least when swapping keys into the Korg. I haven't tried it the other way but am sure it probably works fine. FIts all later SCI units P600 and on except T8 and VS probably. Check for price and stock notes below Ordering Instructions.

Early Yamaha synth keys are found in the SY-1 and 2, CS-10?, CS-30, CS-50, CS-60, and SS30. Check for price and stock notes below Ordering Instructions.

Later Yamaha synth keys are found in the CS-5, CS-15, CS20M, CS-40M, and CS-70M. Also the SK series probably as the SK-20 has them. Check for price and stock notes below Ordering Instructions.

Yamaha DX7 keys are also in SY series, EX5, PF10 and Motif7 (and others that have semi-weighted keys). Korg M1, WS, 01/W, Trinity, Prophecy, and Triton except for LE and 88key also use a key that can be interchanged. Probably other boards as well. Let me know if you use one that has these that isn't listed.(PS. Yamaha still has KX88 keys) Check for price and stock notes below Ordering Instructions.

Yamaha Ridged keys have similarities to DX in spring. Used in the DS-55, S30, and possibly some of the cheaper SY's (55?). Also some combo organs and consumer electric pianos from the late 80's to early 90's like ME-6, HE-8, ME-50, U-1000, EL-50 and spring said YPR9 so possibly it also. Also Korg X3. Thanks Joseph Rooney for the info/pic!

I stock a good number of used keys and some new, all of which you can see an example of a normal white key in these images. Pricing structure is typically just sub retail for more common keys (since although they are used, all the keys are in practically new condition). Ones which are no longer commercially available however special end keys are at least 2x the price. Also more rare keys are scaled up with the value of the synth in mind.
