oh man...thx for that info ;))) greets, rio

hi, i'm not sure where that MIDI options are stored: Keyb.Chn. T/A Split Midd.Note Merger IN OUT Src.Chn.->Dst.Chn. MIDI Clock # 4 off C-3 off Int. IIC1 --- --- on I changed the Keyb.Chn. several times and i have stored the FLASH and EEPROM via midi-sysex: FLASH F0 00 00 7E 40 00 01 00 00 10 00 F7 EEPROM F0 00 00 7E 40 00 01 20 00 00 20 F7 If i send the *.syx back to MBSEQ --> that Keyb.Chn. doesn't changed. I don't get it :) Maybe someone can help. Besides, what is just stored in FLASH and EEPROM of MBSEQV3? Greets, rio

so by the way..., i think the best is, that i will try to change my setup first, to solve that ;). so best wishes :), rio

Hi, TK, i know thats very special and not a bug. But maybe you can give me a hint: I have noticed that a sequence, which is set to "Restart ON" will only restart that sequence, if no other note is playing currently on that channel. Sadly, it's necessary in some setups for me that those tracks are restarted instantaneously by sending a new note in that channel, no matter whether a note is still playing currently or not on that channel (but of course if there is a playing note, it should release it first before restart). So my question - Could that easy to change? If yes, can you give me a hint, if it would not be to complicated. But all in all, the MBSEQ3 is finished....maybe it should not be further changed. I can understand that. best regards, rio
-
Hi all, i've test it...it has no changes. so if someone want to solve that and who has skill in asm and is interested to solve that, then please let us know...my skills in asm are totally bad :) but for me that problem is not priority! so thx for help anyway. best regards, rio
-
hi tk, thanks for help. i'll try this out tomorrow, because i'm to tired... and if it doesn't help --> it doesn't matter :) but i'll response here the result :) Thanks a lot for your fast answer. best regards, rio

hi, i noticed a little strange behaviour (maybe it's a bug) but please test it first by yourself. I have described short the steps, how you can rebuild that: 1. I have configure 1 track with Restart ON and HOLD ON (because i want to restart this track for every incoming key from an external input) 2. I have set a note at the first position on that track, which should be played 3. I press now stop(!) on MBSEQV3 4. Now i play a note from an external input 5. Then I press start(!) on MBSEQV3 6. But now the note will be played 2 times instead 1 time which should be (seems it restartes because it recognize that there was a note there - but it that makes no sense if the SEQ was stopped before). normaly, if the seq is stopped and i have not played a note before - the sequence play the first note one time. maybe it can be solved, or someone can explain me a solution, how i can solve it :) Best regards and thanks for help, rio

now it works, i had in the SET PATH command a whitespace after line, so that was the reason why it has not recognize ;) best regards, rio
-
ok thx. so i will try again at home. But i think i recived a "'make' command was not found" yesterday. Maybe i left something out (PATH definition?). I've installed MSYS and GPUtils allright. I will try and write here an answer again, if it not works... thx, rio
-
And where can i find the make.bat there or how do you mean 'using "make"-command'? http://svnmios.midibox.org/listing.php?repname=svn.mios&path=%2Ftrunk%2F&rev=0&sc=0 thx for help, best regards, rio

Hey guys, i want to recompile the setup_mbseq_v3.asm (3.7f) with my own setup (setup_mbseq_rio.asm) again, but something changed a bit in src-structure over the years. I installed msys 1.10 and gputils too. then i have readen that: http://www.midibox.org/dokuwiki/doku.php?id=windows_toolchain_quickstart but where is the make.bat file in mbseq-directory? so i tried to write an own make.bat for my setup: gpasm -p 18f4620 -I ./src setup_mbseq_rio.asm ..but it can't compile, mios.h and so on is missing...it is in the subfolders....but i don't know, how i can configure correct or where i find a predefinied make.bat. i hope someone can help me... best regards, rio

Yap. The 1st encoder == datawheel, so for my work the 1st encoder is sufficient for all setups... my intension was to use the datawheel only for bpm.... and that it will automatically jumps to bpm-screenor show only bpm for a short time. That makes more sense to me. maybe someoneelse has done that before? best regards, rio
-
nice .... and please can you short describe, how i can solve it or where i get an info/description how i can configure that? best regards, rio
-
I did not find something (in a short search) in forum about using main datawheel for bpm, so my question is: Can the MBSEQV3 application adaptet, so that it is possible to use the big Datawheel only for adjusting bpm? My suggestion is: if i scroll the main datawheel then it should switch to bpm-menu and INC/DEC the value, so that i can change speed easily while playing Best regards, rio

ok, i've drawn the newer PCB with the additional caps. I hope that i havn't forget anything or that there isn't an error. It's only handdrawn. Note: The signal out 1x4 pin header: OOOO (Left Ch, GND, GND, Right Ch) Changes: - 2 x addtional 220nF between 12v and GND, and -12V and GND. - 2 x necessary 220pF parallel to the 22K resistors. - additional 10k trimpot to set/tune 0..5V for gain of both CEM - PAN is opened, because AUDIO IN will be connected to both Audio INs - GND_EXT for connecting GND of C64 PSU Best regards, Rio.

Sorry for delay, .. i havn't time yet, but i havn't forget it. Uploading soon.
-
What type of patch is it? - polyphon patch in mono mode? You can also try following: - switch to a lead patch - start the synth sound by pressing SID1+MENU. - check whether all voices will be played by changing Waveform for OSC1,2,3
-
The schematic is the same like in documentation of CEM3378. I only added the additional caps. The PCB shows, where a ground wire should be or not. Besides, i got trouble creating/converting a schematic in eagle.... I'll make the newer PCB at evening, uploading tomorrow. Best Regards, Rio.

The solution is decribed in following thread: CEM3378 Schematic

Now i've solved that problem of swinging background noise: I'd measured a frequency of 700.000KHz on a oscilograph, which was produced by self ocillating of the TL072 and which modulates the whole audiosignal dramatically. For example: if i put my fingers in the near of that TL072... the whole audio signal was swinging... So if you want to build this schematic above, please don't connect all that ground wire to external c.v. inputs and audio signal inputs (add only one single ground connection between both PSUs directly and a direct connection to that board) and add a pair of capacities (2x220pF) parallel to the 22k at TL072. That schematic will give a negative-feedback condition to that disturbing high frequencies. Schematic: 22k +-----/\/\/---+ | | | 220pf | +------||-----+ | | | |\ | --+----|-\ | | \_____| | / -------|+/ |/ That should solve the self oscilation of TL072 and provides a clean filtered sound. (for people, which are interessted in that, i can add a new PCB screen here too) Best Regards, Rio
-
the problem is solved by adding few capacities at TL072. I'll describe the solution in the cem3378 thread after weekend. Now the filter sounds fine. Greets, Sebastian

If you get no reply after longer delay, let us know.. Best Regards, Rio.

Mike's shop is really ok and sufficient for DIY projects. All my device running fine with his boards ;) and his support is great. The rotary encoder you can get from voti. They are called SW-ROT-1. http://www.voti.nl/shop/catalog.html?SW-ROT-01 You have forgotten the bankstick-board from Mike too! And if you want to buy more than 3 EEPROMs, you can buy these somewhere else (they will be a lot cheaper e.g. at conrad) knobs and datawheel you can get e.g. from ALBS Electronic, but they only accept big orders... maybe you can order somewhere else these things or you canibalize old/damaged electronic devices like mixer etc. ;) Greets, Rio.

Have you noticed the same noises on your installation? I've checked my again. There are 2 noises: the first is net zipper noise. I've solved it mostly by put up new ground lines between the SID+Core+AOUT_LC modules which are in the same case. The second noise is more difficult. Seems the TL072 swings by itselfs and it sounds like a dogpipe, which changes frequency after a while. If I put my fingers in the near of it then the frequency will also be changed. Bad bad...
-
My device sounds with noises as soon as the filter c.v. is connected to filter. Please, listen to that example in attachment. Did you hear the same with AOUT_LC? Has someone notice same behaviour or can someone say where this noises are come from? Best Regards, Rio example-cem3378-noise-wav.zip example-cem3378-noise-wav.zip
