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, Freeman String machine, 360 Systems, Honer Clavinet, and many Organs. (eg. Gibson G101, some Acetone if not all, wurlitzer etc.)
Akai AX80 keys are exactly like Oberheim Matrix 6. ALso Korg Lambda except they have the piece in the middle to strike the rubber switch housing. (instead of the rubber foot that sticks on the other more spindly plastic projection.) In a pinch a Lambda type key could be adapted to suit the purpose.
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. However I suspect these are same as the AX73 above!
Alesis QS7 keys I see are the same as QS6 and QS4 it appears as well as Peavey DPM and Kurzweil K2000 below. They also 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.
Late Odyssey MkIII. Also fits Octave Kitten, later Axxe, Solus and SCI Pro-One. synthparts.com appears to have them in stock. Also Synthfool.com also has them he informs me (I saw an auction recently where someone had adapted original Pratt-read keys in place of the plastic ones. It worked fine. But for original parts hit Kevin up).
ARP Solina keys. I was pulling the caps off old organs keys for a while that fit but were very hard to remove. But now I have a scrap Crumar Stringman whose tops can be removed and lightly altered to work!
Casio CZ1000 appears to be same as CT-655 and 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.
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.
Early Crumar See service pic in DS-1/2 page for metal part of keys on that unit. They have the spring at the rear like the Orchestrator. These tops are also used I see in the Crumar Stringman, Multiman, and Orchestrator and appear to be near identical (in the plastic part) to the ARP solina as well. I would guess MOST of the old Crumars use the same tops. When ordering just let me know if the spring is on the end or more towards the middle.. The early ones like Stringman and Multiman though have springs that use a plastic washer and they are more in the middle of hte metal frame rather than on the end. 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?
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?
Early Fatar These are in the Crumar Performer to at least the Trilogy and also some Siel like the Orechestra 2/OR-400 and ARP Quartet and SCI Prelude version of the same. Note metal clip that spring hangs from that slides in from top of that back piece.
Early 80's Mini Fatar These are in the Siel DK-70. Functionally same as Roland E35 it appears which also was used in E-14 E14 at least I see. Not sure what else now.
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 and EMAX II. Ensoniq SQ1(+)is adaptable also. NOTE: Noticeably browner 'black' keys on DK80 than DK600.
Kawai K3 Identical to Korg Lambda key with weights. 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.
Korg EPS-1 uses this variation of the poly type panasonic key. As you see they are taller and lack the 'features', and rather are more flat on bottom. I don't currently have any of these and not sure what else uses them.(Photo by Ken Andrews)
Early Korg keys come in two minor variations and are used in 700/K-1, 700S, 800DV, 770, PS series, MS-10, MS-20 and Sigma. Also see later Moog synths above. Teisco SX-400, 100P, 100F, 110F, 60F and others? The early keys used in my Korg 700 are about a mm or so shorter than the ones I have in stock! So hey you can always file some off like someone did. The older ones have the key type STAMPED BY HAND it almost appears and the newer and slightly longer versions are identified in the molding process obviously.
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.
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.
Korg Poly keys fit MonoPoly, PolySix, Poly61, Poly800, RK-100, Kawai SX-210/240, and MemoryMoog, and Oberheim OB-8 (OB8) after first few I hear which still used Pratt-Read. Also Akai AX60 and later SCI are nearly identical and can be substituted in a pinch. 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).
Korg X3 keys. Appears identical to Yamaha Ridged keys below. However recipient of some of these tells me he had to do a slight mod with xacto knife to make springs set in deeper. 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 N264, N364, Prophecy, Karma, Oberheim OB-12 and Waldorf MicroQ I'm told. Adaptable to Ensoniq Fizmo, SQ2, ALesis QS4 QS6 and QS7 and Peavey DPM2, DPM3, DPM3SE, DPMSi, and DPM4 with addition of weight THOUGH see Kurzweil K2000 keys for precise match.
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.
Memorymoog keys are same in design as Korg Poly keys.
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
Peavey DPM SI Also fits Ensoniq Fizmo, SQ2, ALesis Quadrasynth QS4 QS6.x QS7.x and A6 Andromeda, Peavey DPM2, DPM3, DPM3SE, DPMSi, and DPM4. This key is very similar to Triton LE except it has a weight and a cut out in back to stick a screwdriver in to release the plastic 'catch' so that the back of the key can lift up.
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. )
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
Roland early-mid 80's I have confirmed that at least JUNO-106/HS-60, Jupiter 6, Alpha Juno 1, W-30, D-10, D-20, 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.
Roland mid-late 80's are used in D-50, JX-10, S-10, and KR-33 take these. Part #22575212 for black key. Totally identical to JX-8P keys except with weights on SOME units.
Roland Later 80's weighted- The U-20, JD-800, D-70, Model 660, Model 760, KR-55, and KR-500. 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.
Roland Later 80's unweighted- D-5, EP-3, EP-5 is same key as above w/out weight.
Roland weighted 90's- AT-50, AT-70, JV-80, JV-1000, XP-30, XP-60, XP-80, VK-1000. These also suffered some of the bad epoxe episode
Roland yoke hinge- These are used in the JP8000, XP-10. The VK-7 and VK77 is a weighted version of the same so you can always melt out the weight on a broken key and transfer it to one of these.
Roland Skirted A- EP-7, KR-350, KR-650, PT-8, PT-1000, These also suffered some of the bad epoxe episode. Check for the pink/red epoxe.
Roland Skirted B- AT-30, AT-80, AT-90, EP-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 but lack the extended front plastic 'weight cover'.
Roland E35 ~5.8" long Fatar mfg. Also fits Roland E-14, AX-7, PC-200 MkII, Clavia Nord lead 2x and Quasimidi Sirius and are functionally identical to Korg I series keyboards above. Nearly identical to Siel DK70 except without extension to hold spring actuator. Same save slight mold alteration of no consequence to Korg i3, i5s.
SCI MultiTrak- These are identical to Akai AX60, Korg DW-6000 and Akai X7000, and are used in Prophet 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.
Early Yamaha synth keys are found in the SY-1 and 2, CS-10, CS-30, CS-50, CS-60, and SS30.
Later Yamaha synth keys are found in the CS-5, CS-15, CS20M, CS-40M, CS-70M, CE20, and the SK series probably as the SK-20 has them. Also DX21, DX27.
Yamaha DX7 keys are also in SY35, SY77, SY99, 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.
