Has anyone noticed a similar behavior ?:
When starting the SEQ V4, it often stops at "Searching SD Card ..." and nothing happens. If I take out the card and push it back in, then sometimes it reads the card (or after the searching sdcard is timed out). Once the card is detected and in the running app, I can always put and push the card without problems.Then the card is always found. The problem only occurs during booting.
I am usingLPC1769 core.
SD Card is SanDisk Extreme Pro 4GB.EDIT:
Once I noticed the following message in the terminal: [SEQ_FILE_HW] ERROR while reading file, status: -7
But if bootup seq and it hangs then I get these messages for the commands:

Then I tested the following: I once pulled out all the midi cables of the connected devices. So far, it could always be booted with SD with a lot of test. It starts hanging again sometime as soon as several midi devices hang on it .. no matter which and how many. It makes also no difference whether I connect via USB or external PSU.

I'm just trying to compile the git master. It fails:project_build/core/seq_cv.o: In function `SEQ_CV_IfSet': D:\Temp\midibox_seq_v4/core/seq_cv.c:154: undefined reference to `AOUT_IF_MaxChannelsGet' collect2.exe: error: ld returned 1 exit status make: *** [project_build/project.elf] Error 1
Did I miss something? I'm compiling for LPC1769 / Midibox v4.EDIT: Sorry, I forgot to switch to the new MIOS32_PATH for my environment variable. Everything is fine.
Best regards,

Hey ok, so did you test the PICs with MIOS Studio ? All I know, it’s hard to damage PICs… maybe the untouched ones give a livesign for their ID there. Maybe someone has experience with PICKit2 for that chips, if you stuck in any case...
I'm interested in the result, if it worked well with the pickit2…
Good luck, greetings rio

Are you sure that you fried it? Maybe only the mios/bootloader needs to flash again (http://www.ucapps.de/mios/mios_v1_9h.zip). Therefor you need to upload mios til 2 seconds after switch on! It should show READY afterwards… Please try it first.
Pay attention about yoir PIC Ids too. You have to chose the correct Id inside mios studio. It also possible to change the ids via http://www.ucapps.de/mios/change_id_v1_9g.zip

Hehe - 17 years! Enormously to see the evolution. For me the most useful features are:
- mixer
- router
- track options, especially the transpose option
- massive support of ports... these controller options right on the board saved additional equipment (and the associated complex handling) - everything can be automated in all. very well thought out.

Hey TK,
Thank you very much for your efforts on the MBSEQ firmware ... when did it all start? It is already a life's work ... Awesome: D
Greetings, Rio
-
Thanks for detailed Infos. maybe it will be good next time to commit what has been changed and for which variant it is (or affects). Thanks and greetings, rio
-
Ok, and what has changed in rev. 2597? Please can you explain it to me? It affects TPD and blm8x8 sources - or I am wrong?
greetings,
rio

It is not good to use further check-ins in this way ... the branch was always cleanly maintained for years. I use the master branch all the time for my V4. At this point, I'm not sure if I can continue build releases from that branch.
-
Please can anyone explain me what the last commit 2597 in repository means:
QuoteProposed UI changes for v4 + (to be discussed in person !:
It is a bugfix or a discussion? It isn‘t clear for me … Is it v4 related or only v4+? If I take a look inside source, it’s more blm8x8 related, right? I hope the master branch will not mixed up for uncertain testing purposes…
greetings. Rio

Unfortunately, I do not have enough idea of asm, but I was able to implement at least a CC 120 (for a chosen midi channel), which reloads the same preset, which internally resets the registers. Maybe it is useful for someone to manually delete the hanging tone. At least you have to add following code in these files:
sid_midi.inc (insert before CC 123 detection: --> ;; check if All Notes Off (CC#123 == 0))
;; ####################################################### ;; # CC 120 reload preset ;; ####################################################### ;; check if CC 120 (CC#120) movlw 0x78 cpfseq SID_MIDI_PARAMETER1, BANKED rgoto SID_MIDI_CC_NoInitPreset movf SID_MIDI_PARAMETER2, BANKED bz SID_MIDI_CC_NoInitPreset SID_MIDI_CC_InitPreset goto CS_MENU_MS_NotifyInitPreset SID_MIDI_CC_NoInitPreset ;; ####################################################### ;; # END MODIFICATION ;; #######################################################cs_menu_ms.inc (insert before program change routine -> ;; This function is called to forward a Program Change event to the control surface)
;; ####################################################### ;; # init/reload preset routine ;; ####################################################### ;; -------------------------------------------------------------------------- ;; This function is called to forward a Init Preset event to the control surface ;; Input: ;; o midi channel in SID_CURRENT_CHANNEL ;; o patch number in SID_MIDI_PARAMETER2 of INDF0 lower value ;; -------------------------------------------------------------------------- CS_MENU_MS_NotifyInitPreset ;; request patch send to SIDs with matching channel number SET_BSR SID_BASE clrf PRODL ; PRODL used as counter CS_MENU_MS_NotifyInitPresetL ;; calc pointer to channel entry lfsr FSR0, CS_MENU_SID_M_CHN movf PRODL, W addwf FSR0L, F ;; check if channel number matches movf INDF0, W xorwf SID_CURRENT_CHANNEL, W, BANKED andlw 0x0f bnz CS_MENU_MS_NotifyInitPresetLN ;; get patch number matches (in this case don't change the patch) movlw (CS_MENU_SID_M_PATCH-CS_MENU_SID_M_CHN) & 0xff addwf FSR0L, F andlw 0x7f ;; copy INDF0 to SID_MIDI_PARAMETER2 and masked 0x7f movf INDF0, W andlw 0x7f movwf SID_MIDI_PARAMETER2 ;; store patch number movff SID_MIDI_PARAMETER2, INDF0 ;; skip if patch change already requested movlw (CS_MENU_TX_M_CTR-CS_MENU_SID_M_PATCH) & 0xff addwf FSR0L, F BRA_IFSET INDF0, 7, ACCESS, CS_MENU_MS_NotifyInitPresetLN ;; request patch change movlw 0x81 movwf INDF0 CS_MENU_MS_NotifyInitPresetLN incf PRODL, F BRA_IFCLR PRODL, 2, ACCESS, CS_MENU_MS_NotifyInitPresetL return ;; ####################################################### ;; # END MODIFICATION ;; #######################################################I know, it's not the best solution (I miss my assembler depth ... actually I just wanted to refresh the SR
). However, you must be aware that this will cause any changes to the preset to be lost. ..most of the code was taken from the program change routine. This CC is useful for me, after the 6581 was used and the SID is still audible after use. I can then trigger this CC to end the hanging sound.

yes you are right, I could now break it down on two devices, where it did not work as expected.
Thanks for the explanation.

I would like to take this opportunity to say "thank you" again. After years of working with it, I can still discover new things, implement my ideas and nice that the firmware for the LPC17 was still in place, which I still use. The device is or remains the heart of my synthesizer & it runs stable & fine - I do not know any other hardware that covers the range or is so flexibly applicable. By the way, mentioned that the firmware is also open source.

Hi,
Yesterday I played around with the loopback feature. If I had set a track to bus 1 then I can already see the NRPN LSB descriptions for the CC inside that track - nice, but If i choose another bus (2,3,4) the standard description of the CCs is shown again. Is that intended or a visual bug?
best regards,

@Rio: please try this version:
http://www.ucapps.de/mios32/midibox_seq_v4_095_pre12.zipo OPTIONS page: new option "Print Notes with transposed value". Enabled by default (due to change in V4.093), can be optionally disabled now.Thank you!

since V4.093:
QuoteMIDIboxSEQ V4.093
~~~~~~~~~~~~~~~~~o notes in edit screen are displayed transposed now
Is it possible to include this representation as an option (e.g. display edit notes transposed: yes/no) in the option page? For me, it's quite difficult to find or remember the original/root notes of the track again when editing live.

hi,
When "Midi Remote Key" is pressed, you can control multiple SEQ functions with different midi notes (which can be triggered by your controller or keyboard):
PS: If you have general questions to "how to use the SEQ", then it's best to create an own thread.

i'm still running v4.091.
There is an issue with the midi input. I cannot enter a C-6 with midi input.
When i watch the "midi monitor" it shows a sysex output on that note.
Also if I play a C-6 while on the "mute" page it will unmute all the tracks. ahh!
I'm not sure how to fix this. Please help.
As i remember, C-6 is the default remote key that is configurable to V4.093 in MBSEQ_HW.V4 file:
################################################## # MIDI Remote Keyboard Function ################################################## # The note number which activates the remote function # 96 = C-6 (some MIDI monitors display C-5) # 0 disables the remote keyboard function MIDI_REMOTE_KEY 96 # The CC number which activates the remote function # (e.g. to control it with a footswitch) # Allowed numbers: 1-127 for CC#1..CC#127 # 0 disables the function (default) MIDI_REMOTE_CC 0..but since V4.094, it's configurable in Option Page, like TK mentioned here:

Hi,
I've been thinking a bit about how to get ride off the SID 6581 'hanging VCA' bug in a different way (except of the use of a noise gate). In most cases, I only want to stop that annoying sound in an easy way at silence - so at the end of a song or a jam. At the moment I just change a preset for SID 6581 core(s) to stop the sound manually. But that is awkward.
So my question: Is it possible to trigger the SID_SR_Refresh for predefined SID ID(s) by an special CC or (or thinkable by "Midi Stop")? maybe configured for concerned core IDs in * .asm?
Sadly, I just do not have enough knowledge of ASM and the SID engine itself, but I can understand some sources looking over it.
E.g. I do not know how to address a SID engine directly for the case of refreshing and if that works as expected. For example, I would like to know how to select the respective SID Core (or how parameters needs to be configured for that use case), which is needed before a SID_SR_Refresh. Pls, could someone possibly point me to the right direction?

"Searching SD Card..." hangs more often on bootup
in MIDIbox SEQ
Posted · Edited by Rio
Can it be that the connection to the SD card is too unstable, or is influenced and would a decoupling cap make sense for the power supply of the reader? Just strange, that once it has been correctly detected, it also works stably. I would be grateful for any help..
