Its this one: Which makes me think Im supposed to connect J2 of the core to J4 of the merger for power. But I cant get a voltage from that. Im a bit confused.

Hey, Im having trouble powering my midi merger kit from mikes shop. Im trying to power it from J2 on a working core module. I can't really find any info on what connection on the merger PCB should be used for power. Only JP4 and JP5 are available and the schematic is confusing me a little. Does the polarity of the power from the core module matter when connecting to the merger? Thanks for any help :)

OK I uploaded version 1.1 software and it works great :) Also the LCD connections tested fine so the screen must just be faulty, Ill pick up a new one shortly. Thanks again for the help TK

Thanks again TK, ill replace the software with 1.1 just now and Im sure it'l work just fine :) Ill also double check all the LCD connections when I get home, and I didnt realise there was a diagnostic script to test it so Ill try that too. If that fails I guess just call it a dead LCD and pick up another one. Cheers man!

Hi folks. I have ordered and constructed a core module from Mike's site, and it works! Ive loaded latest MIOS version onto it and also the Dedicated Force to Scale program TK kindly provided I'm having some problems with both the hardware and software side of my project now. Here is a crappy MS Paint picture I drew of what I wanted to build before I started, that also includes a MIDI merger module which I am still constructing: Anyway, onto my problems. Firstly I can't get the LCD screen working at all. Ive double checked its connections to the core and can't see any problems, but when I boot up the core the LCD just changes to one black top line. I have been using the force to scale without the LCD at the moment as my MIDI keyboard shows which CC values its sending so I know what scale and root note I've selected but it'd still be great to get the LCD working. My other problem is that the scaling program doesn't scale my MIDI notes correctly. In every scale I have tried the program misses out the root note itself. For some scales instead of simply missing out the root note it inserts completely the wrong note, and in some cases on the wrong octave. For example when set to G Major, instead of simply missing out the root note when I press G on my keyboard, it corrects to an F which is incorrect for G Major. Here is an example of G Minor, where the program simply skips the G note altogether, but the rest of the scaling is correct: Now here is an example of when the root note is not just missed out, but replaced with an incorrect note, and on an incorrect octave. This example is root note E, and scale set to Aeolian (Minor): You can see instead of skipping the E this time it inserts an F which is an incorrect note, and inserts it on the wrong octave. Any help would be much appreciated! Kvetch

Just edited this post to move it to Troubleshooting section!

Many Many thanks guys! :ahappy: Im going to drop a donation into development just now, and thanks for putting up with me so far :P

Thanks for the merge, apologies again for cross posting, got myself all mixed up here. Ive got my seq_scale.c and seq_scale.h edited down to include only the specific scales I require, and Im just looking into switching scale and root note via MIDI CC messages. I'm feeling more optimistic about my project now, looking forward to any further input from you guys :thumbsup:

Sure thing TK, sorry about the cross posting Im just getting myself all mixed up here. Id be happy to donate to an open project, no problem at all. Ill donate good money if someone can come up with this, but Ill keep persisting with my own code in the meantime just in case I make a breakthrough. PS a million dollars might take me a while :ahappy:

Hi folks, I am struggling here with some of the most basic principles of my development project Ive been working on. I have some basic functions working but Im really getting stuck fast with most of the concepts. I don't think App development is for me but I really want the box I was trying to build. My rather unusual sales request is to pay a community member to develop my simple project and just get me the source files. Ill load and purchase the hardware and everything. If someone could do this and name me a price, I'll go for it :) So all the box needs to have is one MIDI in port, one MIDI out port. No screen or controls on it. It will accept notes through the midi in from my midi keyboard, force them to scale in real-time and output the forced playing to the midi out. It will utilise CC messages to change scale and root note, these will also come from the midi keyboard. It will use midi CC #1-48. 12 root notes in 4 different scales (natural minor, major, minor pentatonic, major pentatonic) If anyone can help me please let me know! Kvetch

Hi folks. Still working on creating a dedicated real-time force-to-scale box. I have my scale.c and scale.h files made with the scales I require, but I'm totally new to this and I'm getting stuck at some very basic things. I am trying to build a box with 48 buttons, 48 LED's and no LCD. It only requires 1 MIDI In port and 1 MIDI out port. Would Midibox 64 kit be capable of this? Basically I want to play my midi keyboard in real-time through the box and have it output my playing forced to certain selected scales. I only need to use major, natural minor, penta minor and penta major scales, with all 12 root notes. I was thinking maybe 12 root notes * 4 scales would mean I could have a button for each with an LED above each button showing which was active. Perhaps it could be easier to have only 5 buttons, 1 for each of the 4 scales I need, plus a button that when held down would allow me to select the root note of the scale via my midi keyboard. I have the scale files from the midibox seq V4 source code which accepts perimeter (p) as the note to be forced, but I need help with making this perimeter the currently pressed note on my keyboard. Any help would be much appreciated, and Im not sure whether this could maybe be done with the core module alone?

I too am trying to build something very similar. Did anyone message you back about this post? I find the programming sections of the website and ucapps very confusing. And just trying to find an example of the "force to scale" function hasnt been possible. Did you have any luck?

Exactly what I wanted to hear! Now to research for a good while. Any good pages with C commands for force to scale and such? im finding the programming section of the wiki a little confusing lol

Hi folks, first post here so go easy on me :P Basically my plan is to build a dedicated force to scale hardware box for realtime use. The functionality is designed to be very basic, and take a live MIDI in stream from my keyboard, force it to a set scale, and send it out a midi out port. It would change scale via MIDI CC messages also coming from the MIDI keyboard. Im comfortable building electronics and have done plenty of DIY synths and circtuit bending, and I know some basic C programming, so there's plenty of research for me ahead. Im just writing to double check this would be possible before I embark, from what I can see with my beginning research this system would only require MBHP_Core unless I want an LCD screen on it. If someone can confirm this can be done without too much hastle Ill start my full research and build! Thanks in advance! Kvetch
