Da die analogen Eingaenge an J5 wahrscheinlich nicht auf Masse liegen, waere die MIDIO128 zum Testen besser geeignet. Ich habe von diesem Phaenomen schonmal von einem anderen Anwender gelesen, damals war es glaube ich aber nur eine einzige LED, die flackerte. Aufgeklaert wurde es nie (zumindest habe ich keinen Feedback erhalten). Deshalb waere es sehr interessant zu wissen, ob das Problem nur mit der MBSEQ Applikation auftritt. Gruss, Thorsten.

Vielleicht ist der 5A Regulator etwas ueberdimensioniert, und die Spannung steigt zu langsam auf 5V an. Was passiert, wenn Du mal kurzzeitig einen Reset an MCLR# (PIC Pin #1) ausloest? Dazu braucht es keinen Taster, Du koenntest das mit einem Kabel nach Masse ausprobieren. Gruss, Thorsten.

Ja, das funktioniert wie auf der MBHP_IIC_MIDI Seite beschrieben: Gruss, Thorsten.

Do you also get 4.4V when the 74HC595 chips are not stuffed in the sockets? Best Regards, Thorsten.

Error code 01 means "less bytes received than expected". So, it looks like a problem with your MIDI interface. Are you using the latest drivers? Do you have access to another MIDI interface? Best Regards, Thorsten.

From the MBSID V2 changelog: o 8 external switches can now be connected to - DOUT shift register (-> DEFAULT_EXT_SWITCH_DOUT != 0) - port J5 of the core mode (-> DEFAULT_J5_FUNCTION == 3) The switch states are stored in the patch structure, and can be accessed via Control Surface (EXT menu) or via Parameter Change (NRPNs/Knobs/Wavetables) [/code] Note: if you want to sweep over different filter modes, just write the switch selections into a wavetable, and control the position from the modulation matrix. In difference to the CV solution this has the advantage, that you can easily select the interesting combinations, and change the order. Best Regards, Thorsten.

Ok, in this video I used a MicroQ at the beginning. So far I remember, it was a simple saw sound with some filtering and reverb Fx. I just added some additional infos to the video (e.g. what synth is playing at which time) Best Regards, Thorsten.

Time to publish a picture of the BankStick connections. Best Regards, Thorsten.

Hi, crosstalk between analog inputs shouldn't be a problem so long each individual cable connected to an analog input (CORE:J5) is shielded to ground. Best Regards, Thorsten.

Hi, for 36 encoders, you probably have to set the DEFAULT_ENCODER_GROUP_WIDTH setting to 64, as this is the next 2^n value after 32 Best Regards, Thorsten.

Are you able to send the patches with MIDI-Ox? Note, that the "delay after F7" has to be set to about 750 mS Does MBFM return an acknowledge message whenever a patch has been received? Best Regards, Thorsten.

Hi, currently only notes can be recorded, recording CCs is planned for one of the next releases. I guess that not more than 10..20 people have built a MBSEQ yet Best Regards, Thorsten.

Hi, remapping has to be done in main.asm and mios_tables.inc Thereafter recompile the code as described here: http://www.ucapps.de/howto_tools_mpasm.html Best Regards, Thorsten.

Great! :) Best Regards, Thorsten.

No, a bootloader was not used for PIC16F, since the flash size was already very limited. Best Regards, Thorsten.

"Bankstick A not ready" will be displayed, if TL's patchmanager doesn't receive the acknowledge message from the core after a patch has been sent. Are you able to overwrite the first patch? This would indicate, that the PC MIDI Out->MBFM MIDI In connection is ok, and MBFM MIDI Out->PC MIDI In is not working Best Regards, Thorsten.

Which USB interface are you using? (just for the records) Best Regards, Thorsten.

Yes, I used MIDIbox FM, and in the second half MIDIbox SID. Best Regards, Thorsten.

RC14 is available now, it contains some bugfixes. I hope that I haven't broken anything with these changes (normaly the small changes cause the unexpected effects... ;-)) o BankStick write via SysEx now gracefully aborted if only 32k BankStick is addressed and patch number >= 065 SysEx error number 0x11 ("BankStick too small") will be returned in this case o the "send dump" function of the "shift menu" now sends the edit buffer of the selected SID, which also includes the corresponding device ID. BankStick content won't be overwritten if such a dump is sent back. o menu page automatically changed to the previous selection if SID master or slave selected which is running with a different engine [/code] Best Regards, Thorsten.

Yes, the 5 "soft functions" which correlate with the displayed parameters are already there. It is sufficient if the LCD only displays the 5 items, the two unusued LCD lines could be filled with additional informations later (although nobody has good ideas for what to display there...) - most of the MB6582s are stuffed with a 4x20 display. However, my proposal is still the usage of a 2x20 (or alternatively 2x40) display. 2x20, because I'm using the same, accordingly it can be considered that the display screens are layouted perfectly for this size. 2x40, because this is the only straightforward solution for displaying 10 parameters - on a 4x20 it really looks ugly. Best Regards, Thorsten.

There is a nice inbuilt bassline and drum editor in the MIDIbox SID (control surface required). Of course, an external GUI, running on a computer, would be a good alternative solution. The basics are there (full access to sequences via SysEx), but an external editor software is not available yet... A step sequencer is not a common MIDI sequencer - especially because of the quantisation. Best Regards, Thorsten.

thats a good idea, because it also matches with the sequencer concept. If both LEDs lit (green and red), one of the instruments would be played accented. I already built a 4x16 duo-LED/button matrix, but I must say that I would never do the same wiring effort again. A PCB based solution is a strong requirement. Yes, ENC28J60 - Seppoman made some good experiences with this chip. Best Regards, Thorsten.

Are the OP amps directly supplied by the batteries - so, isn't there a voltage regulation? In such a case it's very unlikely to get stable results. Best Regards, Thorsten.

Hallo Paya, willkommen im Forum! :) Die falsche Spannung am Tx Pin deutet darauf hin, dass der Bootloader nicht gestartet wurde. Andererseits: wenn der PIC nicht im Sockel steckt, sollte eigentlich gar keine Spannung anliegen. Ich kann mir das nur so erklaeren, dass evtl. der MIDI Out Port noch mit einem MIDI Interface verbunden war? Zurueck zum Bootloader: hat den jemand in den PIC gebrannt? Ansonsten wuerde ich auch nochmal die Reset Leitung (MRST#, Pin 1) ueberpruefen, hier sollten 5V anliegen. Auch die Oszillator-Pins sind heisse Kanditaten, doch die kann man leider nur mit einem Oszi ueberpruefen - oder zumindest nochmal visuell auf evtl. Kurzschluesse untersuchen. Gruss, Thorsten.

The setup/hold timings are ok, and based on your new experiments, I would say that it really looks like a crosstalk issue between a single data and conrol line, especially because most of the failures are reproducible, but some are sporadic. Maybe it's caused inside the connector that you are using for the ribbon cable? You tested the LCD with "Smartie" - did you connect the LCD with the same cable to the PC? Would it be possible to check this? Best Regards, Thorsten.
