Would any sysex dump do? If so I can make up one of a program.

Also to add to that, it is very easy to control a lot of things you would want, but other things are more difficult depending on the editor you are using. For example 46 | 2Eh | Filter CutOff frequency | 0-127: val | 127 47 | 2Fh | Filter Resonance | 0-127: val | 0 Using CCs 46 and 47 and any value from 0-127 you can easily modulate the filter frequency and resonance, but: 45 | 2Dh | Filter Mode | | 0 | | Bit 0: LowPass on/off | | | | Bit 1: BandPass on/off | | | | Bit 2: HighPass on/off | | | | Bit 3: Voice 3 off | | Using CC 45 and some extra bits you can change the filter mode. I however have not got any of these more elaborate CC instructions to work. I am certain you can, but im using a kenton control freak to record ccs into the sequencer, and its not an easy task to program a complete SID editor. I think, and I may be wrong as I never got it to work on my sid, that you can press the CC button and record all of your changes into the seq and avoiding making any editors etc or knowing the CC numbers and extra bits (This of course would require a full control surface). All the best, John

Hi All, My old SID (Xevious) died and I couldnt fix it, so rather than wasting efforts on that tight enclosure which may have been some of the problem I have decided to make a 2RU version with 4XSID chips (all 8580s). It will be just DIY looking as the old one :) Ive put some initial pictures up on my gallery http://www.dcerecords.dnsalias.com Its under the MBHP_sid_v2 area. I hope it all goes well this time!! All the best, John

Hiya George, Good to hear that theres other K users out there! You should give it a go again for sure. What OS version do you have? Great leaps were made in the final updates for both units. Funny as I have been in 68K mac world with them too :) I have always found them to be very good machines if you stay within the polyphony boundaries. VAST is, VAST and could be explored a lot more with a hardware editor. I do know that the GUI of the K2000 and maybe 2500 is slow to update the screen, but I think you would find that its actual processing does not suffer from this lag, only the screen refresh. Im thinking of an editor that is able to be used without needing to see the Kurzweil, and hence this problem wouldnt matter. I know there are a range of software based editors out there, but it is my dream to not have to have a PC in sight of my studio. Ive been down the PC path as far as it goes, and I found no satisfaction when comparing it to the hands on feel of the hardware. It has its advantages, and I wont knock it, but its just not the same to me. Anyone who doesnt have a Kurzweil, get one now, there cheap and you wont find a better all round synth, sampler, sequencer with FX (noisy tho) for the money. It can be your whole studio if need be!! In any case, id love for this years old sysex mystery to be solved once and for all, and I think this community is capable. Any further info/thoughts etc would be great!! Thanks, John

I do have the manual, it doesnt reveal the full sysex implementation. Ive uploaded the sysex chapter it for you to look at if your interested. I can upload the whole manual if that helps?? What could be done using the info in the zip file if anything? Thanks!! John 30 SysEx.pdf

Hi All, Dont know how many Kurzweil users are on this forum, some I hope! I am really into K2000's!! The K2000 has a huge system exclusive implementation, but it was never released which left the KRZ community outraged for years and made using the synth difficult in some aspects ie real time envelope control etc. I, and others I know, and probably a large amount of KRZ users out there have always wanted a way to control the K2000 in real time in every aspect, and even tho it has a huge midi implementation from CC's it doesnt cover everthing, some areas are badly lacking! I have had this folder sitting on my PC I found ages ago which is a bunch of .h files and a compiler file and some other stuff inc a readme. This folder contains some code which aparently would allow you to develop an editor which uses the whole sysex implementation of the K2000. Im thinking it may have been made for use on an old mac as there is reference to 68K as a CPU??? Im just guessing. If people dont mind, can you download this and tell me what is possible, in laymans terms (im not a programmer) bearing in mind that I would love to see this implemented somehow into a MIOS controller ie MB 64e or similar as a sysex editor for the K2000 synth. Even just a way to get this info to spit out all the sysex destinations for me to program up another editor (Kenton Control Freak or Reaktor or something) would be a huge leap in the right direction!! In fact, any comment by anyone who knows what there talking about might help me to see how to make any use of these files. Thanks!!!! K2KSYSEX.zip

Hiya TK, Here is the log of IIC1 on midiox in an test pattern. When this pattern is recorded into the Kurzweil sequencer the timing is way too fast when playing back as mentioned before. I have also included the patterns as sysex files should they be of any help. Thanks, John IIC1_Log.zip

OK, this is the only thread left :) I still need help, anyone??? Thanks, John

Thanks!!

I searched the forum , and the only result was back to this post :) Anyone got a link handy? Cheers, John

What I am trying to do is to power the Aout module and core from one board. I have bought a transformer to mount in the box with 12v 1 amp. I need 1x 12v + 200ma 1x 12v - 200ma 1x 9v up to 600ma. I was looking at connecting the 12v from the transformer into the core direct and making the PSU for the Aout board shown on the Aout page, but Id prefer to have a board which will do all 3 rails and without strain on anything if possible. If you can suggest a layout I can make on vectorboard that would be awesome! I have all the parts for the Aout PSU now, so if they can be used that would be great. I also have the transformer and IEC panel connector. Thanks!! John

Im keen on some too, whats the deal with the price? PM me if you like, im keen on 4 if possible and if at a good price. Thanks, John

Thanks guys, does anyone have a schematic for a suitable tested PSU?? Its all sounding a little risky.. Or at least the model number of the 2a regulator so I can get one if thats the way to go? Cheers :) John

This is for my sequencer, whos regulator is VERY hot :o now even with a heat sink (2 lcds and all ultra bright leds), is the answer still yes? Id really hate to blow it up. Thanks!! John

Hiya, Im no expert, but from my own similar problem with encoders (different, but similar problems) I suggest that you test each wire going to the pots to ensure connection to the ain board using the multimeter to beep the connection (if you know what I mean, testing for dud wires). Also try if you can to move the faulty knob to another shift register on the board if you have any left (make sure to change the reference in the asm code to reflect this). If all else fails swap the knob out, and the wire and the IC it connects to (if you know everything else works ok). Uploading the midiio128 application also helped me pinpoint what was happening, this may not help you tho. This will show you the value being sent by the knob, if it is not like all the other knobs in its response then you know something is wrong for sure. In my case I didnt actually solve the problem, but I got rid of it by moving the faulty knob to another shift register on the board. It might not help, but best of luck!! John

Still no sound out of the SID. I uploaded the sid connection test and it says pin A0 Is that what it should say??? Maybe the interconnections are wrong? Its a V2 core and V2 sid and I thought it was right... Any suggestions? Cheers! John

The PDF says 7-12V ac or dc, the guy at my local electronics store says 12v ac would be fine, is it? Im looking at setting up a transformer and board for my sequencer to power the Aout and the core, I am going to make up the Aout PSU as shown, but the guy at the shop said I can run the 12V out from the trasformer directly into the core. Has this worked for someone before? Thanks, John

Hiya TK, Just when you think something couldnt be any better, a new version is released!! Awesome work!!!!! A couple of things still confusing me; What master is the track syncing to which is different than it normally would?? Sorry to keep on this topic but its an important one to me :) Im just trying to ask the right question regarless of the name of the feature / concept. Do you have any plans to implement any way to chain tracks at at any stage? I know its probably complex to do. I would love it if at the end of each track there was simply a ->A2 instead of stop or something similar?? If possible, could you give a quick beginners guide to the loopback setting and how this works or should I wait for the documentation?? Is it simply that it will record any and all changes you make on the sequencer ie pressing buttons at particular times etc and takes its own track up to record and play these things back? If so that could be used as a song arranger by making your songs from pattern changes recorded into the loopback track??? Maybe im looking at it wrong?? The random works well, esp as you said when the force to scale is on. I was astounded that as I asked for it, you were releasing it, that is very odd!!! Especially when you never mentioned it!! :) I am merging the input for my kenton control freak (not sending any clocks etc) and I have IIC1 out to the Kurzweil K2000 rack. Ive left the particular routing settings alone for testing this problem. It seems to be playing the sequence back at at least 8x speed. I havent played with any divider or clock settings. When I plug my TR-909 in place to compare the notes are recorded in time without any problems (no settings changed on kurzweil). The kurzweil picks up the midi clock from the sequencer and syncs to it when recording, same with the 909. If there is anything new you would like me to test for this problem please let me know (as with any bugs or features you want tested). All the best, John

Hi Alex, Glad your onto it! Its odd, I have heard of 3 people lately whos bridge rectifiers died on their cores, I wonder if its a faulty batch? Or a its from a common mistake is made which needs to be addressed like an easy way to kill them? All the best, John

Hiya, I pulled the core out of the SID to see if it worked by itself, but it didnt so I swapped it over with another one I have, I got the SID to boot up and all seemed well but now there is no sound!! Will keep investigating, but if anyone knows a good troubleshooting method please sing out :) Cheers, John

Hi All, Im still stuck on this one if anyone can help. Just to avoid confusion, this is the same as: http://www.midibox.org/forum/index.php?topic=7918.0 Should one of these be removed?? Thanks, John

Hi Doc, Thanks for the answer. All of the LEDs basically ground to two points on the DOUT so if I join them to one and add a resistor to it, then take the ground back to the core (will look for 1st ground point, maybe on the regulator??) would that help or will I blow myself up :) Thanks, John

Thanks stryd_one, Ill start with disconnecting the SID power and just trying to get the core to boot so I feel a little better :) Then I can move on to identifying the problem on the SID board. Cheers, John

Hi All, Dont know if this info helps but in the latest V3 seq app I have uploaded patterns to the PC and back again after formatting the bankstick and it all worked as expected. John

Hiya Toneburst, I know it doesnt help you now, but I have found from killing an LCD that its best to have a REALLY cheap one wired up with a ribbon connector to a socket on the board for any testing. Mine cost less than $10. I leave this one connected up until the MB is actually finished, then if it dies it doesnt matter too much. Also as a general question to anyone, what is hot in degrees for the regulator? On my core for the sequencer it is too hot to touch (with a heatsink) and seems to work all the time. I can measure the heat on it with my multimeter, how much is too much? Anyone got a datasheet on the regulator?? I hope you get your problem fixed up! All the best, John
