Teraz to ju? te? Twoje forum. ;)
Ogl?da?em Twoje paczki w??snej robotry - oj pojecha?es bracie, pojecha?e?.
JAk graj?? Mo?esz co? wi?cej o nich napisa?? Gratuluj?! Wygl?daj? bardzo mi?o, tylko jak z parametrami? Mo?esz napisa? jak? maj? skuteczno??, moc i barw??
Czy s? cho? troch? liniowe? BRavo!!!

Cze??!
??dnie Ci to wysz?o. Gratuluj?. Czy to Twój pierwszy projekt?
Wy?lij prywatny mesyd? do TK z linkiem do Twojej wiadomo?ci na forum, i proponuj? przenie? Twój w?tek do dzia?u Poland, tak mi si? zdaje ?e b?dzie czytelniej na forum.
W ka?dym razie gratuluj?. Fajna obudowa i panel, cho? brakuje tylko po??dnych napisów.
Da?bym 5 w skali do 6.

Czo?giem!
NAwet je?li masz cz??ci za darmo to jak wygl?da sprawa obudowy? JEstem daleki od powiedzenia ?e warto.
Powiem wi?cej nie warto - w dobie tak tanich urz?dze? steruj?cych na rynku.
Z drugiej strony co? w tym jest ?e siedz? na tym forum kilka lat, mam przed sob? kilka sterowników i syntezatory FM i SID, a ci?gle mi czego? brakuje - ci?gle co? robi?... tylko nie muzyk?.
Ostatnio czerpi? fun z tworzenia programu do muzyki, a nie z samej muzyki.
To jest kwestia wkr?tu, a nie tego czy warto w sensie finansowym.
Je?li masz wkr?t to i zap?acisz dro?ej ni? za gotwca w sklepie muzycznym.
Warto!!!
?artuj?.
Nie warto!!!
Te? ?artuj?.
JAk by? wiedzia? od razu z góry ?e chcesz wykona? to i to urz?dzenie i koniec - to luz ( o ile nie ma tego na rynku) warto zrobi? to jak najlepiej i mie? z g?owy. Ale je?li podrodze si? wkr?cisz w wymy?lanie nowych urz?dze? to mo?esz zosta? w p?tli czasu - jak ja i Syzyf. Powinienem si? nazywa? Syzyf a nie QBAS :)
Pami?taj ?e nowe do?wiadczenia rozszerzaj? horyzont i droga wydaje si? by? krutsza, a cz?sto us?ana jest ró?ami.
Pomoc masz zagwarantowan? na tym forum. Nie jest trudno uruchomi? i odpali?.

SPDT switches are different than this one used in standard keyboard, so code that I use is not compatible.
-
In the meantime I improved code (thanks kicks from SD ;)) and now we both use this with good result.
Not excellent result - since this code need polishing lockup table with predefined velocity values, and SounDuke report me that sometimes, when he play fast, his keyboard have missing note off message. :-\.
Polishing velocity response is easier, but now I cannot doing it (no free time).
Finding reason why SD take this hang up notes is harder for me - because I never experience this (probably I`m too slow on keyboard). In future we will try finish this project.
Right now it is in ugly asm code style. When I clear this for looking nicer then ... with a little help from my friends... we will try put it on the Wiki.
I personally use this code also with 88keys keyboard with good result.
If somebody is really interested into putting this code into his machine then I can help, but please consider that this is still not finished project.

Czó?ko,
my?l? ?e sysex Ci si? ?le wys?a? i Twoja ostatnia aplikacja wgrana w PICa zosta?a uszkodzona, bez wgranego nowego softu. Powodem mo?e by? - jak s?dz? - s?aby interfejs MIDI, lub ?le skonfigurowane MIDI-OX (o ile tym programem wgrywasz)...
Czy po pod???czeniu zasilania dostajesz na MIDI IN w kompie sysex startowy MIDIBOXa?
Je?li tak to wszystko gra - tylko wgraj jeszcze raz nowy soft.
Je?li nie - to sprubuj wgra? i tak soft , ale po odczekaniu ponad 2 sekundy od w???czenia.
Spawd? czy masz odpowiedni? wersj? systemu, albo najlepiej wgraj go najpierw , a potem aplikacj?.
powodzenia

from my side: with bad switching PSU I get -13V and +11V on FM module and this give me distorted sound.
another PSU (based on big traffo): without connecting to FM module I measure -13 and +11, but after connecting to FM module the voltages I get OK. (+12/-12V) and of course sound was good.
-
Nice design! Very simple, but enough for playing.
-
Wow SD! Congratulations! Great machine.
-
Very interesting demo. Thank you for all your work.

Uffff, one problem less.
Now I can study MIDIrouter. One more time thank you TK!

Hello
I have a problem with get working iic_midi_sw_loopback_v1_0 application properly.
The core module work good with lcd, also I have 2 modules IIC MIDI with latest software related to PIC16f88.
After upload iic_midi_sw_loopback_v1_0 application I see on lcd
Sl1 Sl2 Sl3 Sl4

, so MIOS recognized properly IIC MIDI modules.
After bootup red and yellow leds blink and green led still light on.
Everything look good, but incoming midi data to the core module are not forwarding to IIC MIDI slaves. I left R1 pins on both IIC MIDI modules open.
How can I try to debug this situation? :)
p.s. when I send any midi data to midi in on IIC MIDI module then I get the same midi data on IIC MIDI out, also red and yellow leds flashing.
thanks
edit: I have connected leds in oposite way than this picture

@*jOi~
I cut debouncing since most of my projects with matrixes was keyboards.
What hardware are you use? What kind of problems are you meet?
tried to migrate the code into CI stopped learn C - I can`t help with it.
hardware was 8x16 switch matrix using 2xDOUT and 1xDINThis code was prepare to 4xdin and 4xdout modules. I dont know how it will be work with smaller setup.
Of course any kind of customization can be done, but I`m not prepare (yet) configuration definitions.
no - i just no needed this with keyboard, and I used this timer for velocity counter.i assume you left the debouncing out, as it would consume too much processor power for all the buttons -
Yes, I has problem with not connected ground between +5V ground and +/-12V ground.
My oscillator was very hot, and others part also, but I only changed this oscillator, created connection between grounds and every was good, so I think try finish , upload software and have fun from this super sound.
-
Styrd_1 you are <MAN>! Thank you for help with keeping this zip file.
*jOi~ - yes, it will work with smaller matrix too.
Johnc - have fun with assembling!
I`m ready to try help!
-
have you connected grounds (I mean from +5 with +/- 12V)?

hello
1. what you expect from new one layout?
2. Are you plan use also additional LCD on layout or just take it simple?
If you need only some faders. knobs and other please keep in mind that DIY is not cheap! Its maximally customizable, but not fast, cheap and easy.
DIY-ing will eat your time, power, money. Please consider this before you will build something.
Of course it is sense for build that one like you said, but if you find for this new unit somting special, that isnot possible (or very hard) to do with regular commercial controller (for example using motorfaders, memory of values and names of parameters in PIC, etc...), but programming this, checking, testing
it all will take a few months.
I suggest you try commercial cheap controller (2 octaves, 8 faders, 8 knobs etc...) for check your feeling with Video/MIDI fun.

nice job

I have 2 keyboards powered by MIOS at home, both look similar, also I seen many keyboards parts at service.The reason I want to send you the photo is that the matrix is a PCB attached to the keyboard switches. I thought you would want to see what we are working with.Of course it is any time very interested, but now I need speed up this our process so I no please for pictures.
You said: 8x8 matrix are on keyboard, and I go with this. This is simple.
For me the important is to find good connection configure, and keep it until we finish main program, after this you will can change everything with table.
I would include photos in my post, but I do not have a website on which to locate the photos. If there is a way to do that by direct insertion into the post, somebody please give me some input.OK I see: you think that I will do test virtually with photos? Its impossible. So we will wait for your working MB hardware set.
About your question with photos, I have the same problem all time. Usually I put photos and files at shitty servers, who delete them after period.
I never seek for better place, since always is to do some other things.
see you later!

to TK, jimhenry and stryd_one:
I know that get working application is first good step, but write good documentation is great milestone. Unfortunately I don`t know how to write documentation for that simple scan matrix extension. If this is needed I will try do this in future if no other man do this first.
Why you would like to send me this?I can send you photos, schematics, etc., of the keyboard pcb's.I said that we start from connect one keyboard (16 pin connector split to say "8a" and "8b"). I wrote the way for test if this work, what is no understandable?
Questions:
1. The code you provided is loaded as an application on top of mios?
This is for 18f452, but if you have another probably is is easy to change this, and any MIOS> v.1.7
2. There is no .ini file to configure the inputs and outputs. Its hard coded in the program? The configuration data youi used is same as in my post, with changes?Take easy. We just start - first get working hardware. Look: there is no documentation (I`m to small for this now), if documentation will specify how to connect, then only customize parameters will left. But we must have sure that you connected right.
3. Hardware will require 1 MBHP core, one DINX module(32 pins) and on DOUTX module(32 pins). The DINXs and DOUTXS are wired to the core as in midio128 app. by interconnecting J8 and J9 to the I/O PCB's? I understand the pin order for the DINX, but the pin order for the DOUTX is confusing. Is "SR", "Shift Register"? So looking at the DOUTX Schematic, counting from the J1 end of the board, the SRs (74H595) are numbered 1 through 4. The pin numbers for SRs are:SR PIn # New Pin#SR1 New Pin# SR2 New Pin # SR3 New Pin# SR4
0 31 23 15 7
1 30 22 14 6
2 29 21 13 5
3 28 20 12 4
4 27 19 11 3
5 26 18 10 2
6 25 17 9 1
7 24 16 8 0
Is this correct?
all yes. You explain this better than me. Can you help me with create documentation after we finish? Like you see I have big problem with sentences other than I meet in manuals for synths. :)
Do the column numbers of the matrix correspond to the pin numbering, ie. col#1 is DOUTX SR4, pin 0?Yes I think so. I have no free set (core + dinx, doux) for test again , but if you can please check it and tell us:
simply connect first pin on DINx4 and last pin on DOUTx4 (SR#4:D0) and check if sysex is F0 00 07 F7.
Since you have hardcoded the configuration, I will need a table to identify switch assignments withing the matrix (row, col) so I know how to wire from the DINs and DOUTs.I don`t understand (this sentence was never at all in my Ensoniq`s manual >:( )
Please don worry aboput table - we will create one in next days - I hope... :P
Table is good place for your setup , and must be - I know this and OK lets go with this
Please review my questions and answer as best possible.yes sir!
Considering the potential length of future posts, I feel it best that we go to email to continue.psssst. we cannot now ... you know ... What will think they other?
its joke
Go on please go with test and connect first keyboard
