Hello. Is the PCB still available and what would be the total cost including shipping to Athens, Greece? Thanks

Thank you very very much Thorsten for taking the time to reply and solve a problem once again!! As soon as I finish my MBSid CS3, I will deal with the MBSeq and I will post results of the code implementation, the KX88 is a real gem and maybe others that use it could benefit too from this and I would be more than happy to try to contribute something, even this small, from my side to this amazing community... I think I am not alone in expressing once more deep respect and admiration for everyhting you have done and are still doing for all of us people over so many years! Again, Happy and Creative New Year!

Thank you vm Peter and Gerald for the time you dedicated to respond to this...and Happy New Year!!! I am not much of a programmer, just fast and skillful with a soldering iron and keen on constructions.... would like to enter the coding field, but I am afraid my time is very very limited due to my ruthless work schedule... so I was hoping to achieve 2 things in one construction (mbseq) as described above. I will consider taking the route you suggested... but if I am to invest in yet another box (core mbng), maybe i will save more time by getting myself a yamaha mep4 http://sonicstate.com/digital/model.cfm?modelID=242&catid=7&manid=2.Even better would be to sort this velocity problem directly in the KX88 firmware ( if you are not familiar, with this controller, http://www.sonicstate.com/synth_reviews/yamaha_kx88/11/), but that seems an impossible/ daunting task. The best piano action for my taste even by modern standars, but the velocity problem is common to all of them afaik regardless of firmware... Oh, I guess I am already off topic... Cheers and I will def. come back to you with updates on the matter...

Hello everyone and Merry Xmas! Sorting out things to start construction again after a very very long time - have to finish my single MBSID 's CS Step3, to build a MB6582, a MBFM and finally a MBSEQ - all the PCBS, chips and parts are there, but time is an issue nowadays (not to also mention a jasper - wasp clone- project). So, the question here is if there is any possibility to use the MBSEQas a midi events processor to alter the velocity curve of my Yamaha KX88, which only transmits velocity values >14 (minimum note on velocity is 15). What I would like the MBSEQ to do is to subtract 14 from the incoming velocity values and then multiply, say, by 1,124 to achieve scaling from 0-113 to 0-127, I hope it makes sense. I understand there exists a MB midi event processor, but since I will build a MBSEQ anyway, I was hoping to achieve this goal too... and things will be easier to edit with the double LCD... Thanks in advance for any input...

Hi Thorsten and i feel good to be back in the forum again!! Sorry for the unfinished first post ... I accidentally hit the post button and then i did not have time to edit, because an emergency came up... :) I do have the service manual for the keyboard and I could pm it to you if required, but I think that there is no schemnatic for the KX88 keybed... nevertheless here is the short story of what I would like to do... THe KX 88 is an old MIDI controller 88note kbd (no sounds) which has been praised by many many users as maybe the best feeling piano action keyborad ever manufactured. While the feel of the keys isindeed better than anything else i ve tried regarding piano action, the velocity range of the kx88 is only 15-127 (measured in midi ox and other monitors). No matter how lightly you press a key, the lower vel value is laways 15. Stangely, in the midi specs chart of the kx88 manual it is stated that the velocity range is 0-127! I have tested all keys and itsthe same with all of them, so I think this is not a mechanical issue, but more like a software limitation (0other users experience same issues). I really wanted to achieve the missing 1-14 vel values, so I saw 3 possible options 1) contact yamaha to solve the problem, with a EPROM update,2) alter the firmware myslf, 3) remidify the kbd myslf. 1) Contacting Yamaha did not solve anything, as the kx88 is old (1984) and no one there seemed to know what it was (!!!), 2) is not really an option as my programming skills aRE super primitive plus i do not think there is a source code availabe (THough I could copy the ROM, as I have a chip programmer, I can read the ROM in midiox :)). So this leaves option 3 using your platform for the midibox KB. The thing is, to my understanding , the KX88 does not use the make-break switch approach, as it does not have rubber switches, but it uses all metal switches DX7 style like shown here http://www.syntaur.com/images/3120-Lg.jpg, so i do not know if these switches work in the same way like make break ones.... In these switches there are two metal stops and a middle metal spring that initially is in contact with the upper metal stop. When a key is pressed it touches the middle spring which then travels a short distancfe and gets in contact with the lower stop (I hope i make sense). i believe that the velocity is measured by the time it takes the middle spring to trael from upper stop to lower stop, so in this case only one switch is pressed?. So is the midification possible, and will i be able to achieve 0-127 vel values? I ll try to find a schematic for the keybd and i can send you a pdf of the service manual , if you wish. Thank you in advance

Hi its been a while since i last posted here...i have an old kx88 MIDI controller 88note kbd. While the feel of the keys is better than anything else

hi pm sent!

Hi everyone. I am in the process of building a MB6582 to which I plan to incorporate 4 SSM2044 VCFs (seppoman s pcb x 2). The thing is that I want to have one case for everything - and since I am going to have 4 " unfiltered" SIDs and four "SSM2044 filetered" ones I was thinking that the use of a passive mixer would ease things up. So the question is , would something like this passive stereo mixer do the job? The idea is that instead of having four stereo outputs one foe each pair of SIDs, these outputs go to the mixer inputs, so as to have one combined stereo output of all 4 pairs... Of course a custom panel will be used which will provide thespace for the mounting of the 4 mixer pots. Please tell me what you think, if this is doable, and most important, if it is worth it

Payment just sent !!! thnx for everyhting and waiting patiently for my case

@ Wilba, a bit off -topic, but do you still have any seq pcb/kits available? I m on the list too, but it might take foerever so if there is a possibility to get my pcb/kit directly from you or fussylizard until august, I would be more than happy, since I will only have August available for soldering.... too busy with work all year... Cheers PS I have also pm ' d you but posting this also, in case your answer might interest other mates here too...

@smashtv: Thanks Tim, gr8 to hear things are working for all of us. Just wanted to ask are the pms sent according to the order of the list, and if yes, what number have we reached so far? (eager to get the soldering gun on my hands again.... :)

Thanks Smash! Will be ordering soon!

Smash, is Greece supported in the regular shop, I see the shipping option in the small shop list, but I want to order a core 32 an the M6582 base and CS pcbs and parts, so I will need to do that via the regular shop, but I cant find Greece as an option, WIll you add it or should I order anyway and calculate the cost using another country (and which one?)

Thanks guys! As soon as i receive the filter boards I ll decide what must be done, at the moment I am starting to evaluate the separate filter box solution again, and looking for suitable cases for the one-in-all solution. If I decide the latter maybe I ll build the case myself (could it be wooden ;)) we' ll see...

Apologies for the double threading nILS, I thought about that before posting twice, in the sense that my post has to do both with parts seeking and fleamarket issues, so instead of writing two distinct posts with different subjects and contents, I tried to save some time by writing about both issues in the same post and just posting twice as I did :rolleyes: If that was against the forums rules, by any means apologies again, next time I will separate things ...
