Hi, i want to modify the blm_scalar app a bit http://svnmios.midiboxorg/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fcontrollers%2Fblm_scalar%2FREADME.txt i want to use it in standalone and via midi/sysex... so my question: how to call the BLM internally? when i want to display a "array[16][16]=0 or 1 or 2;" i know i can call it like below but is there a more direct way to use it? thx. mike void APP_Background(void){ u8 chn = 0; u8 note = 0; u8 velocity = 0; for(chn=0; chn<16; chn++){ for(note=0; note<16; note++){ velocity = Seq[chn][note]; if( note <= 0x0f ) { //note<=15? // BLM16x16 LEDs led_mod_ix = chn >> 2; led_row_ix = ((chn&3) << 1) + ((note >> 3) & 1); led_column_ix = note & 0x7; //7 modify_led = 1; } else if( note == 0x40 ) { //note==64 // extra column LEDs led_mod_ix = 4; led_row_ix = (chn&3) << 1; led_column_ix = chn >> 2; modify_led = 1; } else if( chn == 0 && note >= 0x60 && note <= 0x6f ) { //Chn0, note>=96, note>0111 // extra row LEDs led_mod_ix = 4; led_row_ix = 1 + ((note >> 1) & 6); led_column_ix = note & 3; modify_led = 1; } else if( chn == 0xf && note >= 0x60 && note <= 0x6f ) { //Chn15, note>=96, note>0111 // additional extra LEDs led_mod_ix = 4; led_row_ix = 1 + ((note >> 1) & 6); led_column_ix = 4 + (note & 3); modify_led = 1; } if( modify_led ) { u8 led_mask = 1 << led_column_ix; // 90 xx 00 is the same like a note off event! // (-> http://www.borg.com/~jglatt/tech/midispec.htm) if( velocity == 0x00 ) { // Note Off or velocity == 0x00: clear both LEDs blm_scalar_led[led_mod_ix][led_row_ix][0] &= ~led_mask; #if BLM_SCALAR_NUM_COLOURS >= 2 blm_scalar_led[led_mod_ix][led_row_ix][1] &= ~led_mask; #endif } else if( velocity < 0x40 ) { // Velocity < 0x40: set green LED, clear red LED blm_scalar_led[led_mod_ix][led_row_ix][0] |= led_mask; #if BLM_SCALAR_NUM_COLOURS >= 2 blm_scalar_led[led_mod_ix][led_row_ix][1] &= ~led_mask; #endif } else if( velocity < 0x60 ) { // Velocity < 0x60: clear green LED, set red LED blm_scalar_led[led_mod_ix][led_row_ix][0] &= ~led_mask; #if BLM_SCALAR_NUM_COLOURS >= 2 blm_scalar_led[led_mod_ix][led_row_ix][1] |= led_mask; #endif } else { // Velocity >= 0x60: set both LEDs blm_scalar_led[led_mod_ix][led_row_ix][0] |= led_mask; #if BLM_SCALAR_NUM_COLOURS >= 2 blm_scalar_led[led_mod_ix][led_row_ix][1] |= led_mask; #endif } } } }} // END - FOR - LOOPS

hm i get a error: app.c:1094:13: warning: implicit declaration of function 'wmemset' [-Wimplicit-function-declaration] if(edit & (1<<0))wmemset(loop[track].PB, (u32)((8192<<16) + 8192), (sizeof (loop[track].PB))/4); // reset Pitch Bend when i then add: #include <wchar.h> to app.c then error: should i change this: typedef struct storage { u16 PB [512]; u8 SEQ[512] [8]; u8 MSQ[512]; char leader:1; char virgin:1; u8 length; u8 decay; u8 rythm; u16 bpm; } store_t; to this: typedef struct storage { wchar_t PB PB [512]; u8 SEQ[512] [8]; u8 MSQ[512]; char leader:1; char virgin:1; u8 length; u8 decay; u8 rythm; u16 bpm; } store_t; hm what size has this wchar_t?

if(edit & 0x0f)memcpy(&loop_copy, &loop[track], sizeof loop_copy); clever i like that but i planned it more like: check which things have to copyied, so i can copy PB+NOTES, but not CC+Loop-Information, (for default) if i get it right: in your thought i can always copy only one thing: PB, All, Notes or Loop-Info but i can still use memcpy with for example: if( (edit[0]==1) && (edit[1]==1) && (edit[1]==1) && (edit[1]==1) ) memcpy(&loop_copy, &loop[track], sizeof loop_copy); THX for your help guys! for the rest i will take me time on 23.12... today we make fire in the snow, and celebrate the 21.12 to restart the sun-circle happy new sun year, skol!

ok understand, i let the the file describtion in.... oje... there is something wrong with the code, http://wiki.midibox.org/lib/exe/fetch.php?media=phatline:seq-melody-footboard-beta.zip when i make arrays with 8x512, or arrays with 8x1024, the Files on SD-Card is always 5,6kb size, also on 1024 i got hardfaults when copy those structs into arrays (copy paste clear clips), by 512 no hardfault typedef struct storage { u16 PB [512]; u8 SEQ[512] [8]; u8 MSQ[512]; char leader; char virgin; u8 length; u8 decay; u8 rythm; u16 bpm; } store_t; no difference in SD-File-Size! typedef struct storage { u16 PB [1024]; u8 SEQ[1024] [8]; u8 MSQ[1024]; char leader; char virgin; u8 length; u8 decay; u8 rythm; u16 bpm; } store_t; also i initialize all Arrays, but actual most of them (all except the first member loop[0] in the program are 0-out void APP_Init(void){ //initalize 8 Clips with standart values u8 a = 0; for ( a=0; a>8; a++ ) { loop[a].leader = 0; loop[a].virgin = 1; loop[a].length = 1; loop[a].decay = 60; loop[a].rythm = 4; loop[a].bpm = 120; //initiate Pitchbend u16 b; for(b=0; b<512; b++) { loop[a].PB[b] = 8192; } }; //Initiate Pitchbend - copy paste buffer u16 b; for(b=0; b<512; b++) { PB_copy[b] = 8192; } } the 1024 thing i think is clear, it takes to long to calculate all the data, i would need something like a xtask... but i dont figured out how to make out of a i know: i use such things for counters in ms tact (decay-counters, blink blink...), but not for a function that gets called, work something out, and done... for example: static void Decay(void *pvParameters){ //Send Note OFFs after a while portTickType xLastExecutionTime; xLastExecutionTime = xTaskGetTickCount(); // Initialise the xLastExecutionTime variable on task entry while( 1 ) { vTaskDelayUntil(&xLastExecutionTime, 1 / portTICK_RATE_MS); for(DcyNteCount = 1; DcyNteCount < 128; DcyNteCount++) { for(DcyTrkCount = 0; DcyTrkCount < 8; DcyTrkCount++) { if (MeloDecayTIMER[DcyTrkCount][DcyNteCount] != 0) { MeloDecayTIMER[DcyTrkCount][DcyNteCount] --; if (MeloDecayTIMER[DcyTrkCount][DcyNteCount] == 0) { MIOS32_MIDI_SendNoteOff(MelPortOut, MeloOutCh[DcyTrkCount], DcyNteCount, 0); MIOS32_MIDI_SendNoteOn (MelPortOut, MeloOutCh[DcyTrkCount], DcyNteCount, 0);}} }} }//End While }//End TICK 0 >>> 1ms Task...

would assume that all my tracks saved in a single file, and thats not the case, since i need to load the clips independendly for launching via BLM, but also need to load the clips via Program-change also so it ends up with: case 2: //LOAD all Clips - FOR P R O G R A M C H A N G E for( t=0; t<8; t++) { MUTEX_SDCARD_TAKE; sprintf ( filepathL, "sq/%d-%d.sq", t, clip ); FILE_ReadOpen ( &midifile_fi, filepathL ); FILE_ReadBuffer ( (u8 *)file_type, 4 ); FILE_ReadBuffer ( (u8 *)loop[t], sizeof(store_t) ); FILE_ReadClose ( &midifile_fi ); MUTEX_SDCARD_GIVE; //Calculate new Loop Lengths Loop[t] = loop[t].length * MainLoop; } by the way, do i need that FILE_WriteBuffer( (u8 *)file_type, 4 ); //"SQ01" = 4 Positons for what platforms do i need a filetype? compiler says for the line: FILE_WriteBuffer((u8 *)loop[track], sizeof(store_t)); :

i am stucking @ the moment, while i know how to use it instead of my normal arrays, i dont know how to write the whole struct into file... ok here my struct: store_t loop[8] , how can i read/write them now into my FILE? a struct is not named in MIOS32 functions doku app.h (so all functions have access on it typedef struct storage { // to optimize SD-Load-Time, each clips data is stored in this struct u16 PB [512]; // Pitchband inital = 8192 = No Pitchbend! u8 SEQ[512] [8]; // 512Steps, 8NotePolyphony //loop[c].SEQ bevore u8 MSQ[512]; // Motion-loop[c].SEQ of one CC (Control-Wheel of Keyboard //loop[c].MSQ bevore u8 CC [32]; // Save all other Variables into this Array - for SD-Card... //loop[c].CC bevore char leader; // Programchange able? - only 1 of 4 Song-Clips can send Programchanges via BLMatrix char virgin; // is there any data in the clip? need to display on a ButtonLed Matrix-Launcher //loop[c].virgin bevore u8 length; // 1x16, 2x16... //loop[c].length bevore u8 decay; // 60ms... could be set with Encoder, but I dont need a variable, since the melody out will be used by the Triggermatrix... //loop[c].decay bevore u8 rythm; // 4x4=16, 5x3=15 usw... to calculate maximal duration per UI-matrix page //loop[c].rythm bevore u16 bpm; } store_t; app.c , initalize data //Card-Clip-Container store_t loop[8]; void APP_Init(void){ //initalize 8 Clips with standart values u8 a = 0; for ( a=0; a>8; a++ ) { sprintf( loop[a].file_type, "SIGL" ); loop[a].leader = 0; loop[a].virgin = 1; loop[a].length = 1; loop[a].decay = 60; loop[a].rythm = 4; loop[a].bpm = 120; //initiate Pitchbend u16 b; for(b=0; b<512; b++) { loop[a].PB[b] = 8192; } // 8192: inital No Pitchbend! }; app.c , store data //S T O R E Single Clip MUTEX_SDCARD_TAKE; //Write to File sprintf(filepathS, "sq/%d-%d.sq", track, clip); FILE_WriteOpen (filepathS, 1); //write struct FILE_WriteClose (); MUTEX_SDCARD_GIVE; //SD-Card is now free 4 access break; //L O A D single Clip MUTEX_SDCARD_TAKE; sprintf(filepathL, "sq/%d-%d.sq", track, clip); FILE_ReadOpen (&midifile_fi, filepathL); FILE_ReadBuffer((u8 *)file_type, 4); //write struct FILE_ReadClose (&midifile_fi); MUTEX_SDCARD_GIVE; //Calculate new Loop Lengths Loop[track] = loop[track].length * MainLoop; break;

thx good to know! i will try them structs code is for MelodienSpeicher, where arrays[8][512] polophonic played in 16th (Pitchbend, NoteOn/Off), and also hope that dont hurts when using structs u16 PB[8][512] = {{}}; // 8192: inital No Pitchbend! u8 Sequence[8][512][8]={{{}}}; //8Tracks, 512Steps, 8NotePolyphony u8 CC_MSQ[8][512] = {};//Motion-Sequence of one CC (Control-Wheel of Keyboard s16 TrackClipboard[512][8] = {{}}; //Copy actual Track into ClipboardBuffer u8 StepClipBoard[8][8] = {}; //Just a memory container to copy paste Sequencer Steps

to be prepared, today read a lot about structs, and memory-save/performance/code-readable much to optimize .... it seems that there are things to keep on eye, to avoid heavy bus-load ...like order variable by byte size, and others which i cant summize a "i understand"... importend for me is that the the program goes fast thru, i dont have memory problems, i think, since it is a sequencer timing is No1 by using struct it will slow down program-process? a normal variable-array is slower? > time not so importend - in case of loading from SD-Card to RAM, but for RAM-Access-time in the Program, hope that question make sense? then there where people who said, that when i dont use 32bit types, the program have to calc my 1bit 8bit or 16bit into 32bit -memory-slots- and access time will go not so good, other saying that this is only for x86, arm a nother story... dont know: should i use "int" as standard (except for the big sequencer Arrys > memory to low i expirienced today more a 8 or 16bit...) or should i use u8 or u16 instead? i mean when i dont use structs for all those "not clip related"-variables, just single u8 variables make it any differnce at all? -mike

should it does it the same? incl(track) (step) cant wait to try it at home.many thx.4that. mike.

how ever the endgoal is: 128 Program-Change/Songs a 4clips = 512clips 8tracks a 512 clips fileformat: [track]-[clip].sq >>> each clip is a single file which can be called when i Programchange, it loads the first row of clips >>> clip = PC*4 >>> to load a other clip i need to built a 8x8 blm first: the plan is: ----------------tr0 tr1 tr2 tr3 tr4 tr5 tr6 tr7 last PC x - Play-Clip from last Song empty grid x x x x x x x x - Indicate that there is no Song to choose clip.row0 x x x - Play Clips[tr0][cliprow0] of actual song.... clip.row1 x - clip.row2 x clip.row3 empty grid x x x x x x x x next PC x - Play Clips from next song.... so its a bit of ableton like... but more song structured.

good point! its far better the ui is updated directly via srio then via midi sysex cc or notes.. 32th blinking of 16x2 trigger indicatos bling and blang via midi making trouble... for example i have connected a sequencer to a blm(acts as controller) but all trigger indicators are leds from the sequencer to give timed indication isnt there any mb bus? from core to core

oh i had the same, thoughts back in the days... not knowing what a external c-function is, and where the hell they are - thats a thing to learn first to get a point how TK arrange things... since i learned how to wiki, i also document that - for me to remember - and for other to get some inspiration. hmm i see three options: * learn how to NG-Script * learn no NG-Script - learn C instead + get the compiler running on your Computer * ask someone who do the programming for you... but if you want to change something after - you probably have to script or c again. i personally never learned c in shool or mentor... back in the days when max4live come up, i startet with graphical programming (Without c), t he programm i created, i later programmed on TK MIOS32, and i learned only the c-things i needet to get the programm running which i already know -via internet youtube and google researching- i was knowing what i need and want... i cant learn anything that i dont need @ the moment ... i am no expert too, but i make my own devices and jam with my bandmate every week since years... a "only musican" should just ask a friend to help him a musican which want to use custom or setup a custom midicontroller - have to explore that matter and that take time and entusiasm

not use a mpx16... hmm lot of your quests cant handle a akai mpx16, but its small, has envelops, it depends on your "typical"-sampling time for a patch... because here it is very limited! and it has a lot of BAD things like: https://www.reddit.com/r/synthesizers/comments/61ivbx/akai_mpx16s_midi_implementation_is_shit/
