Hello, folks, we might have discussed this before, but I don't remember an answer. I seriously doubt, based on the EPROM chip capacity, that Kurzweil used 128 discrete velocity levels in each of their samples -- there's probably a set of them at specific MIDI velocity levels, and everything else is handled through volume and some other parameters. So, that said, anyone know how many Kurzweil used, and at what approximate break points they set those different layers to trigger? Any direction will be greatly appreciated -- I need to sample some of the sounds from my GX, Pro1, and Pro2, and I want the best fidelity possible, but I also want reasonable file sizes. Oh, and David E, do you possibly have a patch list for the GX bass patch sysex you sent me? I'm still having difficulty getting it to show up in my GX's.

Hello, with the help of dpScreenOCR I have digitized the article, corrected errors and created a pdf. Forgive me for the one or other mistake I overlooked. Many thanks to David for finding and scanning the article! Best regards from Germany Konrad.

Hi all, We've had a K1000 since about 2018 but haven't really dug into the manuals too much (we figured out how to peruse the presets and just enjoyed playing those). I did get familiar with k1000.net and obtained manuals from there. I'd started to read the "Kurzweil K1000 Keyboard Musician's Guide" (K1000MG.pdf) here and there, but not in earnest until recently. When we got the original K1000 in 2018, the seller did tell us that it had been upgraded to some degree, but didn't know the details (and after having done some digging in k1000.net, I don't think in retrospect that we would have understood them at the time anyway!). I remember being a bit puzzled how the manual seemed to indicate a program range up to 127, but I was seeing things in these "100", "200", "300" and "400" ranges, with a lot of repetition. I did find program lists on the site and I did some manual verification of what was in the original keyboard from 2018 (see below). Recently I got a K1000 SE from one of the list members here. It needs a new volume slider (and maybe some other fixes; TBD) and I'm looking to correctly identify it. I've been revisiting the original keyboard as well and am wondering if I've been reading the wrong manual! In my notes for the original keyboard, I have this written down: Engine: v5.32 Setups: v5.10 I have a hand-scrawled list I must have done several years ago, starting from "000" (which says "No Prg Assigned") up to "099" (the unit skips over "100"), then "101" to "163" (this one says "Tuning Note/Click"), then it skips over "164" to "200", then "201" to "299" (it skips over "300") then "301" to "363" (skipping the rest through "400" similarly as before", then for "401" to "493" it just says "(not found)" for each. After "493" it goes back to "000". I have another note saying "Verified to match the "Pro 1 Sounds" list." I might do a similar exercise for the newly-arrived K1000 SE, but I would like to make sure I read the correct manuals. I note that the K1000 SE came with a few bound volumes; sorry for the painful detail here, but I wanted to reproduce the title pages, as I don't believe these particular volumes appear on the "Manuals" section of k1000.net: First one: Musician's Guide Kurzweil K1000 SE Keyboard By Ralph Jones Gary Davis & Associates Updated and Amended by Romeo Music, Inc. (at the bottom is the KMS address block) Second one: Musician's Guide Kurzweil K1000 SE II & SE II Extended (address block) Third one: Version 5 Addendum Musician's Guide Kurzweil 1000 Series Synthesizers With Version 5 Software Would it be helpful to add these to the PDF files on the "Manuals" page, or, if anyone is familiar with these, were they superseded by files already available there? Finally to the actual point of my post here: I got the idea to provide a kind if "first steps" procedure for someone who acquires a 1000-series instrument of any kind. Considering the upgradeability of these instruments, what it says on the front panel from the original factory instrument may belie what lies under the hood. I'm imagining such a procedure would tell you to press some sequence of buttons to get info like those "Engine" and "Setups" numbers, and maybe some other kinds of identifying info. Hopefully having that info, it could be mapped into a table that would include a mapping to the proper manuals and maybe even the proper program lists etc. Is this a silly or infeasible idea? Apparently our original 2018 K1000 is in reality a "Version 5" machine - I had no idea what "v5.32" really meant until I got these new manuals when the K1000 SE showed up the other day! That is probably more due to my ignorance in properly digesting what is on k1000.net, but I'm wondering if there's a way to provide a bit more direct guidance for total noobs. I'm feeling I should forget reading "K1000MG.pdf" or "K1000ProgRef.pdf" and instead use the new ones that just arrived... Any thoughts, suggestions, etc. appreciated! Thanks, Chuck

Hello, folks. So my repair guy tapped on the relay, it thunked, and he plugged it in and pressed the power button. A capacitor right by the front power button got hot and let all its smoke out. This can be a couple of things -- that cap was needing replacement due to age, so it failed when power got into the system. Or there's something else wrong that overloaded that cap. There's also the biggest list of possible reasons -- something I don't know about. Anyone got any ideas? Nicole Sent from my HAL 9000 in transit to Jupiter

Okay, for those of you who are new to this, or have forgotten, here's the way this works. David Brown got Kurzweil to give us the right to burn update ROM chips as long as it wasn't for profit. That's why there's so much binary file stuff on k1000.net. I don't know anyone with a chip burner, so I don't have a resource for it (David did all of mine). The upgrade from an SX to a Pro2 is worth the effort, because you get some wonderful sounds. And the 5.x OS versions have some useful features.

Hello folks, I've been around here for a very long time, and I love these machines (Better love them, I have thirteen of them). My one black sheep 1000GX has been a problem child -- first it didn't boot. I had a friend resolder the P1 connector. That got me the other common bane, black boxes fever. Back in the dark ages that meant the relay hung, so I sent my friend to the k1000.net site, but he didn't find a good picture of where that relay is. He tapped on what he thought was the recalcitrant relay, but there was no joy from that. Anyone know anything else that gives the screen black boxes? This is a non-upgraded 1000GX -- I want to get it working before I worry about finding someone to burn me an OS5 upgrade. Anyone got any ideas (other than giving it to someone so they can anchor their boat, I'm not doing that). Nicole Sent from my HAL 9000 in transit to Jupiter

There is very little info online about the Pro-2. I found a review that suggests the Pro-1 was released in 1990, but nothing on the Pro-2. Does anyone have any info on this (ads, flyers, reviews, etc.)? Link to Pro-1 review: https://www.muzines.co.uk/articles/kurzweil-k1200-and-pro-76/7528

Hello everyone. I have joined this list after this morning upgraded my Kurzweil 1000. It has been several years since I used this application. Between my last use of K1000 and now, I have installed an Index Everest embosser. In setting up the properties for K1000 to properly print to this, I notice three choices for correctly forcing new pages. Form feed, vertical tab and skip lines. K1000's default are 40 characters per line, 25 lines per page. These can be adjusted. There are no settings for binding space and number of blank lines at the top of each page and page number position so I presume the embosser just looks after those. The setup is Windows 11, and I use the supplied Index driver which is networked. Experimenting of course, but if others have found the configuration which works - I'd be pleased to learn about it. Thanks. Vaughan. Vaughan Dodd Vdodd001@... +6421 784 856

Hello folks, I received this email recently from the Groups.io tech folks, and wanted to make sure I put an announcement out for folks! I'll just paste it below, but basically Groups.io is having to re-verify some users' email addresses due to one of the email servers being blacklisted as a "spam" server by a security provider earlier in the month. In order to fix that, they're requiring some (but not everyone, it seems) to re-verify their email addresses. I looked through the members list here and we have several folks who need to complete this process ASAP, so I wanted to get a message out to you all. Email from Groups.io (bold emphasis mine): ---- You are receiving this email because you are an owner or moderator of one or more Groups.io groups. We are in the process of reverifying some of our users and we wanted to make sure you knew what was happening and why. For more detail about this, please visit the Reverification FAQ, at https://groups.io/static/reverifyfaq On Saturday January 13th, 2024, an anti-spam service called Spamhaus labeled one of our email servers as a spam sender. This caused any email service that uses Spamhaus to stop accepting email from our server. Because of this, we began a reverification process and sent out reverification emails to a subset of our users on Sunday January 14th. Spamhaus lifted their block on Monday, January 15th, 2024, but we need to continue the reverification process. You can see which, if any, of your users are affected. Go to the Admin section of your group and look at the Members page. Next to each user's email, there may be a badge with the letters RI or RS. RI means the confirmation/reverification is in progress, but has not been completed. RS means the confirmation/reverification has been successfully completed. Here are the next steps in the reverification process: On Sunday, January 28th, group emails to people in the RI state will be disabled. Messages from moderators and login link emails will still work. Until February 11th, people will still be able to reverify themselves and the RI and RS badges will still show up in the Members page. After that, members still in the RI state will be removed from groups. The activity log entry will be Membership - Member Removed, with the added reason of reverification failed. For domains where no reverifications happened, no invites or direct adds will be permitted going forward. If there is a valid person on one of those domains, they should contact support@groups.io to have the domain ban lifted. We apologize for the inconvenience this process may cause, but it is necessary to ensure that we are able to continue delivering group email reliably. Thank you for using Groups.io. Best Regards, The Groups.io Team ---- Please let me know if you have any questions! Hope y'all are doing well in the new year. Thank you, Max Thompson

I'm hoping someone on here might be able to give me some guidance. I acquired this keyboard in non-working condition. It only shows blocks on the display. The first thing I had to do was replace the eproms because it only had one out of two eproms populated. I burnt the Pro76 eproms and added the three sound roms it was missing. I went through all the checks on k1000.net a few times. The power supply is giving proper voltages with no ripple. I started probing everything. I see tons of activity around the 68000 and anything associated with it. Lots of pulsing for the address and data busses, etc I see virtually no activity around the arnold chips and everything that comes after the arnold. I'm not the greatest with digital stuff so I'm at a bit of a loss. Is it likely that both my arnold chips are dead or that some input is wrong and that is preventing them from operating? Any advice would be appreciated.

Hi folks, Glad to have joined the group here. We got a used K1000 keyboard almost five years ago; when we bought it, the previous owner said that it had been fully upgraded (paraphrasing), but of course at the time we didn't understand the specifics. The list of sounds matches the "Pro 1" sound list here: https://www.k1000.net/sounds-pro1.htm; the "Show Version" menu option says "Engine: v5.32" and "Setups: v5.10". So far we have just been naive preset users, not really even knowing how to move around properly in the menus. The unit was in storage for maybe a year or so but a couple of weeks ago I got it back out for my daughter to use. I recently printed the manuals and started to read them a bit, having been interested to get to know it better when I find some time. Then suddenly this week... All was fine until a couple of days ago; my daughter complained about it playing two notes at the same time and that appears to be the case. I did some testing against another keyboard and to me it sounds like the Kurzweil is playing what I'd call "imperfect fifths" when you hold down a single note. I looked at the "Transpose" parameter for each layer from a few different randomly-selected sounds but didn't find anything other than zeros, save for one patch that was transposed an octave (it was set to "12"). I'm wondering if it's malfunctioning, such that the "hard reset" is the only option here, but I'm loathe to do it because I am not sure if there are any custom programs from the previous owner in there somewhere - I went through the full range of sounds (000-493; with 401-493 saying "(not found)") and the lists (000-099, 101-163, 201-299 and 301-363) matching the "Pro 1 sounds" lists). I'm confused by the FAQ (https://www.k1000.net/faq.htm#faqpvsid) saying that in the Rev 5 products, the RAM programs were in "location 255 down" - I don't know if this means 000-255 or 201-255 in the "Pro 1 Sounds" list - I was under the impression that these lists were all ROM sounds from the myriad ROM chips that get installed. Hopefully I did my homework well and the description above is helpful - thanks in advance for any recommendations! Chuck

Hello everyone! New K1000 keyboard owner here since last month owner :-) and very happy to have found this community. I have taken some time and am still trying to get to know this beautiful machine better with the help of the precious collection of infos on the k1000.net site. Before unmounting the main board though, I would need some little advice concerning the flaws explained a little further down. Hope somebody can help :-) So, here is what I have so far: roms installed: u50 u51 u54 u55 u58 u59 the unit seems to be in original state without any modifications the relay on the mainboard is a Matsushita with clear top (have already ordered a Panasonic one just in case) I am only testing through the headphones for now (!) and it sounds good, all keys play, ram works, I can save sounds in user memory Have slightly dusted off the interior and the mainboard, then did a hard reset and went into diagnostic mode, runned all self tests with one UART fail • LCD VISUAL TEST ok • BUTTON TEST ok • PROGRAM ROM TST ok • SETUP ROM TEST ok • RAM TEST ok • BATTERY BAK TST ok • TIMER TEST ok • UART TEST ER19>KEYBD UART DATA ERROR U102 ER19 ADDR>780001 EX>0000 OB>FF00 15-(ER19 BITS)-0 BBBBBBBB******** • ARNOLD 1 TEST ok • ARNOLD 0 TEST ok • SOUND ROM TEST ok • ONE SAMPLE TEST ok • MIDI LOOP TEST ok • SINE WAVE TEST ok • SEVEN SAMP TEST ok Now my problems: *1)* the last program is 179 (tuning note), not 184 !? after comparing with the program list from the manual I realise 5 programs are missing: 160 (mono pressure vibrato clarinet) 158 (poly pressure vibrato clarinet) 148 (pressure tremolo vibes) 138 (mono pressure strings) 132 (piano & vibes) It is as if they were just not on the ROM ??!? Can somebody explain that? *2)* Programs 03 through 08 are not playable over the whole keyboard (see list below), which means some keys to the left and some keys to the right just make no sound. This occurs of course with all associated programs that use the same sample soundfiles. Changing the low note and the high note of the layer in the edit menu doesn't change anything: program 03 (choir) G#1 to G#6 only program 04 (vibes) F#2 to D7 only program 05 (acoustic bass) A0 to E4 only program 06 (trumpet) C3 to F#6 only program 07 (baritone horn) D#2 to A5 only program 08 (clarinet) F2 to G#6 Funny enough, the range is different with each of these programs, ROM tests show no errors. Other programs like 01 (grand piano) play fine through the whole keyboard. Still, I pushed down all roms slightly, dusted them off and at first sight the eprom legs don't seem to be corroded (?). Until I am not sure that the problem doesn't lie elsewhere, I'd rather not take them out, because they seem to sit in there quite tightly. So much for now - I hope someone can give me an advice. greetings from Berlin! Jules

Hi All, Since repairing my K1000SE, I bought another K1000, replaced both LCD's with OLED screens and upgraded all the ROM's to Pro-76 (or K1200 Pro 1 Expander) equivalent. I love them but I have a question w.r.t. MIDI latency. Sometimes I drive the K1000's over MIDI from a Korg D1 piano. It often seems like I'm hearing chords spread out, and even the start of the chords is slightly delayed, although the latter is not on every patch..... I hear it mostly on piano patches. Has anyone experienced this? I'm wondering if the sample-based patches - like piano - may be slightly late just due to the way the piano hits have been sampled and cropped (unlike synth patches where the waveform generation starts immediately). When I listen to the Korg D1, it's sounds are more immediate. But maybe it's just me. It's hard to do a double blind test. :-) BTW I still haven't been able to get the K1000SE aftertouch working yet. Cheers, Michael
