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;

* Using structs to read in data, e.g. from SD card will speed up things massively, as every further read may block i/o.
* Memory alignment should only be a problem, if you access data all the time, tens of thousands of times per second :), if you only frequently need some data, don't worry too much, these modern microcontrollers are orders of magnitude faster than old machines. Use the correct memory size for your data and you will be good.
* What you need to worry about is the data size of your program, so use the smallest possible data type in arrays.
In short, our core is very fast, but has only very limited ram. It can calculate like a boss, but can only store 3x more than your old C64 :)
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?

thx has worked:
FILE_ReadBuffer((u8 *)Sequence[track], sizeof(Sequence[track])); //u8 Sequence[8][512][8]
FILE_WriteBuffer((u8 *)Sequence[track], sizeof(Sequence[track])); //u8 Sequence[8][512][8]
call: SD(track, clip, job);
for example: SD(6,1,2); //track 6 dont matter, ProgramChange 1, Load all Clips
SD(0,7,1);//track 0, ProgramChange 7, Load single Clip (clip 7-0.sq)
SD(0,1,3);//track 0 , ProgramChange 1, Store single Clip (clip 1-0.sq)
SD(2,1,4);//track 2 dont matter, ProgramChange 1, Store all Clips
SD(2,1,5);//track 2 dont matter, ProgramChange 1 dont matter, Copy track 0-0.sq 512x8 times on SD-Card = Make filestructure = initalize SD-Card > take 20 Minutes

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

much less beautiful

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.

What is the calling procedure? can you send me (PM) the project? I need a bigger view.
I think structure can resolve write and read but I need to know how it is called.
I'm not at home, nothing to do in the night in my hotel room, I can write something even if I haven't got any hardware to test it...

maybe the bitshift takes to long... or sd access is to slow... or code is just waste...

hi
save my patches with FILE_WriteBuffer like this:
// 16Bit Pitchbend-value to 2x8Bit value - to get a saveable format PB8[0] = * ((unsigned char *)&PB[track]); //low byte PB8[1] = * ((unsigned char *)((&PB[track])+1)); //hi byte //Fill CC-Array of Clip CC_SD[0] = clip_is_virgin; CC_SD[1] = Rythm; CC_SD[2] = Loop_Length[track]; CC_SD[3] = BPM; CC_SD[4] = SetDecayTime[track]; //Note-Data of Clip sprintf(filepathS, "sq/%d-%d.sq", track, clip); //First Pattern --- will be later copied 511 times! sq/8-512.pb FILE_WriteOpen (filepathS, 1); FILE_WriteBuffer((u8 *)file_typeBank, 4); //"SQ01" = 4 Positons FILE_WriteBuffer((u8 *)CC_SD, 32); //Track Variables like Looplenght FILE_WriteBuffer((u8 *)PB8, 512); //2x8Bit Pitchbendvalue x 256 Steps = 512 Blocks FILE_WriteBuffer((u8 *)Sequence[track], 2048); //Track, 256Steps, 8NotePolyphony 1x256x8 = 2048 Blocks FILE_WriteClose ();
i want to save the Pitchband also, i but this is 16bit, and that cant be Written, i need 8Bit Values, so my my 16Bit Pitchband-Variable is named PB[track]
it is done by:
// 16Bit Pitchbend-value to 2x8Bit value - to get a saveable format PB8[0] = * ((unsigned char *)&PB[track]); //low byte PB8[1] = * ((unsigned char *)((&PB[track])+1)); //hi byte
so far ok, QUESTION is: how to combine low and hi byte back to the 16bit Variable PB[track]? (after FILE_ReadBuffer is done)
next question is how to split a multiy-array in low and hi bytes variables: for example PB[track][256] --- which is the Pitchbend-Information - over 256 Steps in a Sequence.
thx 4 helpß

switching / jumping between the 2 "cores" onfly to use for example in live performance , when during the sequencer "core" run the song
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

After a number of years running up-down-in-out of dozens and dozens and dozens of threads ,
thousand of posts and hours dedicated / missed
to get all info and helps necessary to complete a MidiBox Unit (Hui controller ,"NG", Sequencer),
at the end for all projects a very extensive knowledge of the C-Code is essential for get a full working unit (unfortunately)
,
i.m.h.o. MidiBox is a great project because the true "Force" of this device is the possibility to obtain a customized device controller not available on the market ,
(ok so true it require a large number of hours for soldering and assembly (time is money!!! ) + parts cost )
considered that many used midi-usb controllers can be found today for very low price , seem to really not have logical "sense" start with a MidiBox project ,
But (as wrote above) the fact that a customized controller device not available on the market can be obtained with the MidiBox projects
give to this Device a very strong "force point" ,
that said ,
the "issue" about the extensive knowledge of the C-Code required is a so big limit / stumbling block for a large number of "potential" users
,
that have the sufficient electronic knowledge for assembly/soldering the hardware required ,
but not for the software settings/customizations ,
then the question is :
There is really not a way to make the "software" project part more "friendly" and simple ? 8-I
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/

i need rackmount . with desktop case or simular would be fine. not too deep
-
na 300mm dont fit in my flight cases. thought more in the size of your desktop cases. they dont fit?
-
is there a case for the rackmount panel?

multitrack record, recorded with zoom livetrack12,
made with one JP8080 for all tracks (also drums)
overdubed with the Midi-Clock to Audio, Audio to Midi-Clock technology in order to drive a midibox seq light multiple once after a nother...
info about midi-clock to audio:

cool idea... i also want such device.

i want to connect one Encoder directly to J5a
i know that in my Code i have to
initalize this pins:
// initialize pin 2 of J5A, as Digital input with internal Pull-UP //connect to ground MIOS32_BOARD_J5_PinInit(0, MIOS32_BOARD_PIN_MODE_INPUT_PU); MIOS32_BOARD_J5_PinInit(1, MIOS32_BOARD_PIN_MODE_INPUT_PU);
and i also can observe the state of the J5a pin by putting following code into APP_Background:
MIOS32_BOARD_J5_PinGet(0) MIOS32_BOARD_J5_PinGet(1)all clear so far, and working good with buttons (with hardware debouncing ):
how does a Encoder-Code look like (without any Acceleration), and how does Hardware debouncing look like (the same like for buttons?), i want to use as less code then possible...
thx 4 any tips

store 16bit variable to 8bit FILE_Writebuffer
in MIOS programming (C)
Posted
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:
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)); :
