  1. Fatar 61 key keybed controller question:

      Hi @FantomXR since i couldn't find the mentioned thread, could you please post a link or thread title? I'm currently deciding between NG vs KB for a masterkeyboard project. It looks like you can't have buttons and displays with KB, so i'm intrested in a fast(er) scanning NG version. Thank you very much!  
  2. Frontpanel Design (diy attempt)

    I need some help with my last two posts. Can anyone help? Thanks in advance! ps. Would opening a new thread per question be better for getting answers?
  3. I'm sort of in the same boat and started nonetheless, but haven't finished something yet. My main issue is having many hard/software related questions and a somewhat small Midibox community. I'm often in need of specific help that can't be found elsewhere. Btw thanks to all trying to help out us beginners!    
  4. Frontpanel Design (diy attempt)

    What serial register (select row) configuration is better? (1) Wilba DIO layout (http://www.ucapps.de/midibox_seq/mbseq_v4_dio_wilba_layout.pdf) uses the select row SR (M1..M8) for Btns and LEDs (at the same time?). (2) Duo LED matrix layout (http://ucapps.de/mbhp/button_duoled_matrix.pdf) has Btns and LEDs splitted with each their own select rows (DEFAULT_SRM_DOUT_CATHODES1 > D0-D3 to LEDs and > D4-D7 to Btns) I wonder why, if (1) is working as well.   I want to place 32 LEDs and 32 Btns on each pcb. Should i go the 8x8 route (2) or a 4x8 based on (1)? I'd think (1) with a 4x8 matrix should be the best, right?
  5. Frontpanel Design (diy attempt)

    I inspected the seq_blm8x8.c source and it seems if i'd limit seq_blm8x8_current_row to 4 i should have a 4x8 matrix. Can someone confirm this?
  6. Visual Studio Setup

    Looking further into all the project files it seems to me that i have to copy/convert the 'Include Pathes' inside .cproject file to <IncludePath> inside .vcxproj file. Is this correct? Can someone who is using Visual Studio give me some hints how to migrate the project?
  7. Visual Studio Setup

    As a start i imported svn.mios32 source files into VS, but get numerous include errors 'cannot open source file'. After adding some include directories to the project i could get rid of some of them, but i wonder if this is the best way. There must be a way to import references from the makefile, right?  
  8. After a fresh Windows 10 and Visual Studio 2017 Community installation i'm trying to setup the toolchain again. Should i install the old MSYS-1.0.11.exe or a newer MSYS version via mingw-get installer? Or maybe minGW-w64? Which option i should chose? [1] MSYS-1.0.11.exe (old all in one installer) [2] msys-1.0.19-1 (to be installed via the newer mingw-get installer/package manager) [3] minGW-w64 (looks like an active project in contrast to minGW)

    I also consider 2x 74HC595 and 3x 74HC165 (1x BTN matrix and 2x for encoders) per PCB. May i ask which MBSEQ_HW.V4 (standard_v4, wilba, tk) you use for your two 8x8 matrices? Furthermore i can't figure out how easy it would be to setup two 4x8 matrices (should be enough for my design).

    Thanks for the warning. Would you get bleed mixing 2.0, 2.1 and 2.2 Vf LEDs or is this a save range? How does the bleeding works in a matrix? Can i mix colors per row/column (e. g. all on D0 are green and all on D1 are yellow)?
  11. Frontpanel Design (diy attempt)

    Thanks @ilmenator I'm trying to figure out how easy it is to have two 4x8 matrices instead of one 8x8. I want two identical frontpanel PCBs (8 colums/steps each).   standard_v4/MBSEQ_HW.V4 ################################################## # LED assignments to DOUT pins # SR = 0: LED disabled # SR = 1..16: directly forwarded to DOUT pin # SR = 17..24: forwarded to a 8x8 LED matrix ################################################## ... ################################################## # Button assignments to DIN pins # SR = 0: Button disabled # SR = 1..16: directly triggered from DIN pin # SR = 17..24: triggered from a 8x8 button matrix ##################################################   If i'm correct, i can configure my own IN/OUT matrices per SR = 17..24. But i'm not sure about it. I'd like to know what 'forwarded to a 8x8 LED matrix' or 'triggered from a 8x8 button matrix' means? Which matrices, where can i set them up?

    Thank you! So you have two identical PCB sandwiches (2x2) for each side (8 columns per left/right side)?  Each side has its own LED/BTN matrix?

    Hi @latigid on may i ask you if your left/right frontpanel pcbs are identical and how your BLM matrix setup works? I'm trying to do my own frontpanel and it may be the best to make it compatible to some others supported projects. Would be easier to maintain if a new SEQ version gets released and more beginner friendly. My idea was to cascade both (left/right) frontpanel pcbs like it is generally done in the Midibox system with DOUT/DIN/DIO modules. For my simple layout that would mean each frontpanel pcbs has one 4x8 BLM matrix. But it looks like SEQ does not support multiple 4x8 matrices in the MBSEQ_HW.V4 files out of the box. Thanks in advance! ps: i opened a thread:

    Looks like there are two matrices (in MBSEQ_HW.V4 files): BLM (Optional BLM Matrix) BLM8x8 (Additional 8x8 BLM as used for Wilba's Frontpanel) But i don't fully understand for what they are there. What means optional/additional? Could i use them both in parallel for my own purposes (BLM > left FP and BLM8x8 > right FP)? Maybe i should ask @latigid on how his matrix layout works? He seems to have two identical pcbs too.

    Thanks for your encouraging words Peter! What are low current LEDs in your book? For me the 2mA ones, as they are sometimes labeled like that. But those are very dim and would surely lead to brightness problems in a matrix. Regarding 8x8 matrix: that would lead to unfavorable wiring on two splitted frontpanel pcbs, right? Or would you put one 8x8 matrix on each pcb and connect only half of the matrix?
