So, after some time and changes in my studio, i have just fire up my seq v3. All day playing with it (just forget how fun this machine is), so by now im seeing "mios 1.9f" so, its possible to update to the last version (1.9h) is it safe ?. thanks.

Thanks for the info, i have edited the post. Thats a good idea adding a SEQ to my modular :) Cheers

Hi Im selling my Midibox Seq V4, it as been in my studio for quite some time now, and it was really fun to built and to use it live. Unfortunately in this last 3 years i didn't use it at all, one reason is that my whole idea of performance didnt involve the Seq, so its time to move on and im betting the one who keeps it will give a proper use to this wonderful machine. Some specs: i have built this monster and it took me quite some time, at the time i was giving my first steps towards electronic diy stuff and this was my first project, lots of doubts and also lots of ideas that come out of this enterprise, luckily this forum always help me a lot, awsering questions and keep me positive about all of it. I didnt built a faceplate, was my intention but as soon i was starting playing with this baby i totally forget to make one, also i like the aesthetic of not having a front panel, the Seq as 2 midi in / 2 midi out but is prepared for one more in and out, (i have put the plugs but didnt solder them to the board), the rotary encoders in the front have the top caps, but they are missing from the photos because i was cleaning it and forget to put em back. The machine is running and dont have any errors or crashes the O.S is the last one, and i can throw a Power supply in the sale, the box was my creation, and is solid pine wood, the connections in the back a a proper newbies work, but its all good, no shorts or bad connections. I dont know what to ask because i cant come up with a value,(for the parts i have spent about 300€, wood box 45€ and a lot of days working in it) so if you can make me an offer i will appreciate, also im looking for modular stuff (Makenoise Modules, Intelligel, and a System A-100 (case) from Doepfer)

Hi, im looking for trading a Elektron Sidstation (i do not have the original box), great condiction and with o.s 1.33 . Im looking for 1-Sherman Filterbank 2-Yamaha • FS1R 3-SONY PCM-D50 4-NAD Stereo Pre Amplifier with Phono input - C162 well if you have something else pm me with offers

I have found the problem :D Its all related to the two jump wires on the core "Two isolated cables have to be added at the bottom of the PCB (see also quickview). They are only required by special modules (e.g. IIC devices, SID module)" Well after burning my eyes and mind thinking what was wrong with the banksticks i decided to distance myself, and start to build the iic, as soon as i put the two bridges required for the iic, a shinny light bursts my mind.. I reconnected the banksticks and voilá, the banksticks get formatted one time and thats all. Also the iic midi its good and working. So for all of those who have problems with the banksticks, just remember to put the two bridges in the core first.

sorry for my ignorance but i dont know were to search.

same reading on both vss/vdd 1.8 v vss/wc# 1.8 v And i get the 1.2 and 1.8 when they are formatting I was updating its not 5.8 but 1.8 and they are oscillating, i was getting wrong numbers because they were bad connected

how can i debug a core error ?

I bought 10 ic 24lc512, and i have tested all of them in a single probe (so i think the ics are fine),also the banksticks get formated (its not a bankstick ic problem but some other thing). Maybe my IC are not compatible with mios (24lc512i/p) I just dont know, i have tried all approaches and the error stills happens .

i have made a single bankstick and connected directly to J4 on the core. And re-solder de banksticks board with some bridges . But i have found some problems regarding the setup.asm file that might give some light on this subject. Last night i was editing this file (setup_mbseq_v3) to change the CS# adress. #define DEFAULT_BANKSTICK_MODE_CS0 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS1 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS2 5 ; Mixer Map (using CS2 to ensure compatibility with Atmel EEPROMs which only provide 4 CS addresses) #define DEFAULT_BANKSTICK_MODE_CS3 4 ; Song mode (using CS3 to ensure compatibility with Atmel EEPROMs which only provide 4 CS addresses) #define DEFAULT_BANKSTICK_MODE_CS4 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS5 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS6 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS7 2 ; 64k (this is the default setup) What i notice during the format of the banksticks is this : apparently banksticks CS#2 and CS#3 skip the format process, but what is more strange is that, after the format processes all the others CS# it tries to upload the songs to this same banksticks over and over again, and dont stop. After i change the setup to this. #define DEFAULT_BANKSTICK_MODE_CS0 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS1 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS2 2 ; Mixer Map (using CS2 to ensure compatibility with Atmel EEPROMs which only provide 4 CS addresses) #define DEFAULT_BANKSTICK_MODE_CS3 2 ; Song mode (using CS3 to ensure compatibility with Atmel EEPROMs which only provide 4 CS addresses) #define DEFAULT_BANKSTICK_MODE_CS4 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS5 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS6 2 ; 64k #define DEFAULT_BANKSTICK_MODE_CS7 2 ; 64k All banksticks are fine and they format (but still have the problem in every start up "formating every power on) So i came to the conclusion that for some reason my banksticks dont support Mixer Maps Storage and Song Mode Storage.

Hi . Same problem. Bought from mike midi shop the bankstick board Bought 24lc512 i/p from farnell. So i decided to make a probe with 1 chip on it, the problem maintains (every power off/on another bankstick format) . i have tried everything, (changing the lines on J4, testing each chip with a prob) (edit the asm, over and over, closing A0, then closing A1....) nothing as changed, and im out of ideas on what to try next.

Problem solved. It was strange i let it cool down for some hours and after that everything went to normal again. I still dont know what the problem was. Hey Tanstaafl looking great that design. Its more fun that way (pdf style) if beginning a new seq, make a print and thats it all stuff in one single page.
