Here a Block-Diagram> How does the Melody Retrigger works? Here 1 Trigger-Voice: (all that *8 and you have the trigger matrix) EDIT- the Melody Retrigger now works in a ther way.... i use RTOS task for decay-time-not-off-things....

horrible to isolate a code there... :huh: .. when i take the whole seq stuff (that i dont need, my program need those resoureces)...yes of course it work... but then to integrate in my code: , with taking the seq_file.c and file_g.c it is not done... in order to use it i have to delete or replace or // all that stuff that i dont have (all that referenced ui.s tasks functions and whatever)...by ending again and again that the compiler find this and this not because i have to delete or replece something else anywhare to, or a reference what is then again needed by other things... change makefile, mios lokal config, overwrite _file.c and _file_g.c and then all the headers... overwrite complete without testing it step by step, the whole networkt ... hardcore! but i dont give up! of course i will lose a lot of hair on this! or i take the whole sequ. dont change anything, add my code, and live with all that unwantet stuff. and hope that the onchip memory is enough. this makes me feel stupid WHAT I AM NOT!

hey pete thx 4 the clarification :happy: lets step forward with that little overview (studying this files) i came to the point that i have to think about "how my application" should work and not SEQV4... like i did bevore, step by step function to function... (anyway that stripdown-trial and understand-trial was good to get a bit overview) so first i have to find out what i need in the UserInterace (ui is in app.c) app.c 1st Menu Page: LoadBankNumber --- LoadBankName --- StoreBankNumber --- StoreBankName --- Store --- Load Then How many Banks i will need: 511 What about the Systemconfig? - ok let say it is the first Bank (0). turn on the device, proove SD-CARD... if there is no Data, it has to be made, (make files, fill with Defaults, 4 matrix e.g. a 1:1 routing) For this case the SEQ app.c "void SEQ_TASK_Period1S(void){.... " is a good starting point, it formats the Card, and call seq_file_.... to make files... a really good point to start :excl: so whats then on the SD-Card? |CARD-FILES:_ | CONTENT_____________________________ | 0.b | u8 SysVariable[127] | | | 1.b | u8 MtxPart[8][8][8] | | u8 SongName[8] | | u8 UI-Variables[127] | | u8 ChordSet[6][6] | | u8 PCSet[16][16] | | | 2.b | u8 MtxPart[8][8][8] | . | u8 SongName[8] | . | u8 UI-Variables[127] | . | u8 ChordSet[6][6] | . | u8 PCSet[16][16] | . | | 511.b | u8 MtxPart[8][8][8] | | u8 SongName[8] | | u8 UI-Variables[127] | | u8ChordSet[6][6] | | u8 PCSet[16][16]_________________________ So the Filename is a interger: that is good 4: to sort the songs better on Computer... to select them better in the LOAD/STORE MenuePage. So i have to write/adapt following addition files tm_file_bank.c tm_file_bank.h tm_file_system.c tm_file_system.h tm_file.c/h ... keep the hirachy flat... i try to make that in app.c... next is to define the file path stored on the the sd card, i decidet to put all files in a folder called "tm" locatet in root: root/tm/

lets start... since i dont get anywhere the last days, trial and error, youtube, try to understand file.c, hard stuff, Now I start to document the newbe way to awarness... ok I will expect this all --- so no proof if this is true or false... Problem: the Blueprint for SD-Card - Filemanagement is: SEQV4(SVN) in all Variants, too bad that that app is complex10 && because off its complexity the code is diffused as functions on different locations - and are referenced (#include) in the main-loop (app.c) so take a look at the top of the app.c: #include "file.h" #include "seq_file.h" #include "seq_file_b.h" #include "seq_file_g.h" #include "seq_file_c.h" #include "seq_file_gc.h" #include "seq_file_hw.h" #include "seq_file_m.h" #include "seq_file_s.h" #include "seq_file_bm.h" file.h is a hEADER-File, all what is in there will be copied from the compiler in the app.c i found there: definitions, types, prototypes which are importend for the FUNCTION "file.c" --without these head you can CALL but nobody will hear...nobody will do, nothing will happen exept a error message from the compiler "not declared difintion..." file.c :is a Function that is specified under "Modules" if i write in app.c "FILE_CheckSDCard" the Function File.c get called "CheckSDCard" File.c do then with that something and returns it something to app.c... all this Commands begin with "FILE_" file.mk: aka MakeFile, normally when you build an hex-file you ask your compiler to "make" it, in this file -as far as i understand - is describet how-2-make-it... I assume that i dont have to change anything in file.c/h/mk ok now whats that, take a look @ seq_file.h, seq_file_b.h, seq_file_bm.h... seq_file.c, seq_file_b.c, seq_file_bm.c... I found in different application similar files (mbcv_file.h), I assume these are User/app files. by looking in the Header files, they differ a bit some store Banks, some System Variables, but they are almost identical (..._file_a/a/c/d/e.h) except for the first one those ..._file.hÅ› it define possible Error Codes that could come back if i call these _file_a/a/c/d/e.hÅ› // used by seq_file_b.c #define SEQ_FILE_B_ERR_INVALID_BANK -128 // invalid bank number #define SEQ_FILE_B_ERR_INVALID_GROUP -129 // invalid group number // used by seq_file_m.c #define SEQ_FILE_M_ERR_INVALID_BANK -144 // invalid bank number #define SEQ_FILE_M_ERR_INVALID_MAP -146 // invalid map number // used by seq_file_bm.c #define SEQ_FILE_BM_ERR_FORMAT -156 // invalid config file format #define SEQ_FILE_BM_ERR_READ -157 // error while reading file (exact error status cannot be determined anymore) ---hm lets take a look @ app.c again, search for e.g. SEQ_FILE_B_ERR_INVALID_BANK, SEQ_FILE_B_ERR_INVALID_GROUP, SEQ_FILE_BM_ERR_FORMAT ...nope nothing - am confuzed... but results for: SEQ_FILE_B_.... like this: (SEQ_FILE_B_ none error) ...u8 bank; for(bank=0; bank<4; ++bank) str1[7+bank] = SEQ_FILE_B_NumPatterns(bank) ? ('1'+bank) : '-'; by searching the file.c module documentation i dont found any "NumPatterns" I assume seq_file and file are more seperatet then i thougt (up to now i dont any clue anyway, trial and error) .... ok then take a look @ the seq_file_b.c; search for that "NumPatterns" ///////////////////////////////////////////////////////////////////////////// // Returns number of patterns in bank // Returns 0 if bank not valid s32 SEQ_FILE_B_NumPatterns(u8 bank){ if( (bank < SEQ_FILE_B_NUM_BANKS) && seq_file_b_info[bank].valid ) return seq_file_b_info[bank].header.num_patterns; return 0;} ok i can see clear now, the seq_file_b.h define that error messages, that are User/App coded in the seq_file_b.c - these messages are callback messeges, which must be specified... let me proove this by searching the seq_file.c yep here are those error messages: ///////////////////////////////////////////////////////////////////////////// // create a complete bank file // returns < 0 on errors (error codes are documented in seq_file.h) s32 SEQ_FILE_B_Create(char *session, u8 bank){ if( bank >= SEQ_FILE_B_NUM_BANKS ) return SEQ_FILE_B_ERR_INVALID_BANK; ..._file_a/b/c/d.c are specific Memory Tasks, like SystemBank, PatternBank,SongBank, NameBank....... whatever... ..._file.c manage all Memory Tasks, after booting or loading a "Master Preset" it comunicate with all Banks, i expect this "manager" is needet to avoid multiple acces on the sdcard... app.c then dont have to do much... so now its time to code something stripped down, write a variable array on SD-Card & Recall it... & lets proove what is right and what not... lets say if we need this triangle "dreifaltigkeit" or it can be done with app.c and _file_a/b/c/d.cÅ›

I built with your help something like an router...so i merge DIN and Midi to my Function where now almost everthing is... stripped down this it is: #include <mios32.h> #include "app.h" #include <FreeRTOS.h> #include <task.h> #include <queue.h> u8 CCinPort = 33; u8 CCInChn = Chn9; //Function "Router" Variables u32 Cc = 0; u32 Cc_value = 0; u32 port = 0; void APP_Init(void){} void Router(u32 port, u32 Cc, u32 Cc_value) { MIOS32_LCD_Clear(); // clear screen MIOS32_LCD_CursorSet(0, 0); // X,Y FIRST LINE MIOS32_LCD_PrintFormattedString("%d %d %d", port, Cc, Cc_value); //Ports are Midi=0 and Din=1 } void APP_Tick(void) {} void APP_Background(void){} void APP_MIDI_NotifyPackage(mios32_midi_port_t port, mios32_midi_package_t midi_package){ if((port == CCinPort) && (midi_package.chn == CCInChn) && (midi_package.type == NoteOn)) {Router(0, midi_package.note, midi_package.velocity);}} void APP_SRIO_ServicePrepare(void){} void APP_SRIO_ServiceFinish(void){} //called after the shift register chain has been scanned void APP_DIN_NotifyToggle(u32 pin, u32 pin_value){ if(pin < 256) {Router(1, pin, pin_value);}} // void APP_ENC_NotifyChange(u32 encoder, s32 incrementer){} void APP_AIN_NotifyChange(u32 pin, u32 pin_value){} void BUTTON_NotifyToggle(u8 row, u8 column, u8 pin_value, u32 timestamp){}

yes you understand enough... because the answer is 1A a self written function which is called from both DIN and Midi!!! @ flag and state.... the word state is enough i youtube this...thx @ take a look on this... i make it more readable the next days - and then 2000lines here

hello can give me someone a littel C instruction... i dont write my code here, because its 2000 lines long.... it is more a generell newbe question then something specific --- i think its a standart knowhow that i just have to know, to do more complex progamms... anyway: my APP has following Midibox -standart-functions: void APP_Init(void){} void APP_Tick(void){}//counts DECAY Timings, and do with that NOTE-OFF Handling void APP_Background(Void){} void APP_MIDI_NotifyPackage(mios32void APP_MIDI_NotifyPackage(mios32_midi_port_t port, mios32_midi_package_t midi_package){}//do Note-ON-Handling, MidiInCC void APP_SRIO_ServicePrepare(void){}//filling the 8x8 LED-Matrix void APP_SRIO_ServiceFinish(void)}//nothing void APP_DIN_NotifyToggle(u32 pin, u32 pin_value)}//All Buttons, and Virtual Matrix Buttons void APP_ENC_NotifyChange(u32 encoder, s32 incrementer)}//Menue Encoders void APP_AIN_NotifyChange(u32 pin, u32 pin_value)}//4 Potis void BUTTON_NotifyToggle(u8 row, u8 column, u8 pin_value, u32 timestamp){}//nothing.... with the MidiBox Buttons that are connectet to the DIN-Modules --- I am in the "DIN_Notifiy" Lo and HIs: I do there most things that happens only one time: when i hit a button - something happens - up to an end, where nothing happens... everthing runs perfect in this closed box, I am happy like a childe with a blinking led speaking robot, and aslong i dont need a time counter like and DECAY-Time it is serial and very logical (for me)... I run into problems when I want to Remote this APP extra via "Midi_Notify" -like an footboard (MB Buttons and Midi Note On/OFFs controll the some Code): - problems? > many code strings are locatet in the DIN_Notify, from Midi-Notify I dont have access to the DIN --- in Din there must be Triggerd something... else nothing is happening there.... So my idea was: Is there a way to force, fake, call from MidiNotify to DinNotify? >>> MidiNoteOn comes in >>> fake Din Pin HI, >>> MidiNoteOff Comes in >>> fake Din Pin LO Event??? like "force pin = 32, pin_value =1" away of that serial processing of triggers (without program loop) i found also loops here "App_Tick" and "App_Background" --- so i run into a world that is not mine... not mine in the past... so tried a workaround, by puting my CODE-Strings (Calculations) under the "APP_Tick" Function, and manage-ing the DIN and Midi HI and LOs --- by working with "Done 0" "Done 1" Flags...to avoid endless triggers on code blocks (each ms) but with that i get so much flags, unbelieveable... @the end off the program there is something and in top this and 2000 lines between others.... mindfuck... and @ the end of day the machine does anything but not that what i want off... (maybe because there is so much code...) Bevore this workaround, i used this TICK only for LCD-Menue & for the Decay-Time for the NoteOFF Events (Note On I do in the Midi-Notify Tread) I come from max msp, and all there is TRIGGER, that triggers this and that, and after a serial way of happenings the code ends... --- so I like that "Midi or DIN trigger a event" very much... for me its logical... that Din and Midi Events in differnt Treads/Functions cracks my head --- help please. michi

... hmm my sequencer and in near future blm4x and tdp also needs case and frontpanel... but i want 19" rackmount because of being more live musican then studio human.

u gut pm, take it.

i had in mind that it was dualcolor...just switched on - uuups you are right > single color (me to many years... it was a nightmare to get that mexico encoders replacements...)

i cant test it, i dont have controllsurfaces with ledrings on it. looks like the "morph assign" feature that the nordlead/rack III has - the NordRack III has a LEDRING Interface: When you press & hold one of the Morph Assign Knobs (Velocity, Keyboard, A.Touch, Wheel) all Ledrings are turned off, and then by turning one or more Encoders you assign it to the pressed Morph Source (e.g. a CC). The Ledrings inital Position is "middle" if you turn it left, the Morph Source is substractetd, turn right and you add a Amount of Morph.... in the Nord Rack Case you have then -64 +64 of Maximal Morph Impact (not 127) Since the Nordrack has "Dual-Colour" Ledrings, this ammount of Morph is indicatet by a differnt colour (Grenn is the morph Factor, red is the CC amount before the morph additon) this could be simulated on the MB-Side with a blinking LED, or with a "show morph" button. that meens techically: the morph CC is addet by the ammount off the morph factor the morph Factor is set Holding the Morph-Assign-Knob + by turning the Destination CC, the result is a int from +-64, for example we turn "+32" now release the Morph-Assign-Knob - now we are in the normal "Perform-Mode" I now turn the Destination-CC to 64. (=Ledring-Value) when i now turn the Morph-CC, to 127, the Resulting Destination-CC-Value will be 96. a cool feature, but only when you see what it does by indicating it wih differnt colours, or some blinking...otherwise it is confuzing...

hopefully the whole hardware thing and synth remote....get something rolling called -preset morph-.... i love soundmorph, i could jam the whole day arround, and then i make a snapshot/save Preset, on gigs the croud dont give me the time to jam the whole day... >>>some crossfade between sounds is "doing less sounding much killer feature" with the possibity to exclude some CCs from that morph - like: LPF-Cutoff, Fiter-Env.Ammount, >>> - for all the filterheadz out there who still got to have controll over the sound while morphing. >exclude the morph Controller from morph fade, morph the morph may end in endless cc traffic sessions... Select the "to be morphed CCs" by hold a "shift"(morph)-Button, now all LEDRINGs are blank by turning a Encoder the dedicatet Ledring lit up > that indicate that this CCs will be morphed.... Next to the MORPH-Button is the Morph encoder, and next to the Morph Encoder is one of this Dispays, that shows on the left the actual Preset, and on the Right the GOAL/Destionation Preset. 2Encoder and one Button should do the job...

YES-thankz

I use Trigger Channel 7 + 8 as "Midi-Poly-Melody - Retrigger" - Trigger -Channels Connections: Midi-In-Port1: DrumSequencer Midi-In-Port2: Melody Source on 2 differnt Midichannel (selectable for each Channel per Button) Midi-Out-Port1: Melody Goal on 2 differnt Midichannels here a video, with some functions off the "Tekkstar" and its Brain the "Trigger Matrix" https://vimeo.com/117018283

Situation: 100BPM Midiclock on CH10 over UART-IN-Port to LPC17 Core - from there i route the Clock to the UART-OUT-Ports in additon to that Midiclock i send a lot of notes (polyphone, drumroll > 2x8Notes 32th trigger) on two differnt channels (8Notes 32th retrigger per channel) The Clock routing i do this way: void APP_MIDI_NotifyPackage(mios32_midi_port_t port, mios32_midi_package_t midi_package){ MIOS32_MIDI_SendPackage(UART0, midi_package); MIOS32_MIDI_SendPackage(UART1, midi_package);} below this code is then my application... inclusive the poly drumroll when my Application send out a lot of Midinotes (Poly-Note-Roll) the BPM dedection on My Synthesizer now slow down about -6BPM so a few ticks are not going out, or to late? is there a way to give a task more priority (Task=midiclock)? or is it better to take a incoming "Start" (0xFA), and start with that 24ppqn Tick (0xF8) with a User (UI) definied BPM rate that is static, and send that out UARTs, until "Stop" (0xFC) come thru the UART-Ins that stop the tick. what is a intresting alternative, by that way i could double or half the BPM, to have more flexibility on Synths like slower LFOs or Arpegs. Here is my Testsetup (yes it is a part of the "Tama Techstar" or "tekkstar" midibox...) https://vimeo.com/117018283

geh 45° passt eh, midibox is art!
