Hi ! I did indeed enable the "spi_midi" switch in the bootloader. I didn't check the midi in ports, only the midi outs. And yeah, the first 2 midi in ports worked indeed! But the other two don't seem to do anything?! After replacing USB0 by UART0, and compiling a new hex file, also the first midi out port worked! But the other three don't seem to do anything?! Now I've got new stuff to check, I'm a big step further, but any suggestions about the not working midi ports are welcome. Thanx!

Yes, that's how I imagined it would/could work, like the gm5x5x5 modules, only over ethernet instead of usb. But I also can imagine that it isn't that simple. I've quite some difficulty to understand all those digital/programming stuff. If I read it I understand not half of it, and I found out that I learn most by just starting to play with it. That's why I purchased your board, but maybe it's just too high level for me. Ok, this I understand, so I uploaded the SPI MIDI Test app (I guess that's the demo code you mention), but if I send midi to the RTP-MIDI nothing happens on any of the onboard MIDI sockets. I just started to read the MIOS32 Tutorial Code Examples, the first two are about sending midi packages and parsing them from one port to another. It seems a good starting point, but I don't know how to implement RTP-MIDI. As I said, maybe it's a too high level for me, should I wait for a RTP-MIDI router app. But if it's do-able with some hints I'll like to try it myself. Cheers, Roel

Hello, Last month I bought a PCB for the RTPMIDI_CORE_STM32F4 and an OEM Kissbox module from Benoit to experiment with. I have some sync issues (hick ups) with Ableton and wanted to try if it would be better with this midi over ethernet stuff. I also really like the idea that I can reach my midibox stuff over ethernet with different PC's without switching cables. But I have some trouble getting this to work. The PCB finished OK, all LED's do what they suppose to do, I can reach my Kissbox module with the Kissbox editor. After setting up a session with the RTP-MIDI driver I was able to reach my STMF4 board over the ethernet with MIOS Studio and upload the project.hex file I created from the mios32_spi_midi app from the SVN Repository. But I still see only the virtual midiport I created with the RTP-MIDI driver and I don't know how to acces the MIDI In/Out ports on the RTPMIDI_CORE_STM32F4 PCB. In the mios32_spi_midi directory there is a mios32_config.h file and this seems the place to activate the ports but there's something strange: // how many SPI MIDI ports are available? // if 0: interface disabled (default) // other allowed values: 1..8 #define MIOS32_SPI_MIDI_NUM_PORTS 4 // enable 4 USB MIDI ports #define MIOS32_USB_MIDI_NUM_PORTS 4 It seems that both SPI MIDI and USB MIDI ports are all activated (4) Why don't I see them anywhere? and why it says that the interface is disabled by default (0) while there's a 4 behind NUM_PORTS?

After studing the WTPA2 manual again I found this sentence: "WTPA is fully capable of handling and generating running status messages (and interpreting NOTE ON messages with a velocity of 0 correctly as NOTE OFFs)." So my problem needs a different solution, any idea? Cheers, Roel

I agree with eptheca, I'll stick to the midi standard and ask the WTPA2 forum for a solution. Cheers, Roel

I think I suffer from the same issue. I have a WTPA2 8-bit sampler wich I can play manually, or by midi. Manually works great but I can't get tight loops of e.g. 4 bars. Midi from ableton works also great, I can record really tight 4 bar loops, and by playing the loop an octave higher it doubles speed, great machine. But if I play it from my SeqV4 I can record music (it starts recording on CC#3) but when I play the sample with notes it only triggers the sample to play, but it doesn't stop at the end of the note. It does stop at the end of the notes comming from Ableton. I didn't understand yesterday but as I read your/this thread now I think this is the issue. I also would like note-offs, so any help or comments appreciated!

Hello, I just came along this kickstarter project: https://www.indiegogo.com/projects/axoloti-a-digital-audio-platform-for-makers Looks really cool espescially with your custom made midicontroller! Cheers, Roel

Wow this is great, superb work!! I'm building a new studio/workshop in my garage now and this machine would be the perfect data centre. I'm lookinig forward to build one myself.

I succesfully assembled this PCB, in the end. I made the stupid mistake to solder most of the shiftregisters the wrong way. I started OK, did a double check etc. but half way I went wrong and noticed it to late. I just desoldered them using a blow tourch?! and put them back the right way. This was more difficult because the surface wasn't flat anymore, but it worked. Not the first time of coarse, one little pcb trace was damaged, so when I attached my TPD it did strange. But after beeb-testing the pcb traces of al shift reisters I found the bad trace, repaired it and then it worked! So my only usefull tip is beeptesting your work with a multimeter to check your connections! Succes! Roel

Hi, I'm making an instrument for schoolkids, a cabinet/chest of drawers, to make music with that schools can rent from a educational art institute. In fact it's just a midicontroller (MIDIboxNG) with an integrated mini PC running Windows7 and Ableton Live9. The teacher has to power on the machine without a screen or mouse etc, just hit the power knob, and at the end of the day hit the powerknob again so the PC will shut down. Everytime Live should just loads its template without asking for anything, like crashreports etc. Is there a way to achive this? I found this threat https://forum.ableton.com/viewtopic.php?f=4&t=161743 but I don't know how to do this exactly. Any help will be greatly appreciated, I have a truly great machine but now it hangs on such a stupid issue. Thanks in advance and cheers,

OK Clear, I thought so, but somewhere in the menupages I saw a LCD screen that looked like a drumtrack with a drumtrack-name. I thought maybe I'm missing this thing, but now I can let it rest. THANX again! Cheers, Roel

Maybe someone can confirm that it's just not possible?

Hi, I hope I'm missing something completely but I can't give my drum tracks a new name. I renamed my synth tracks (note and chord tracks) in the Event menu>Edit Name, and the new names are shown in the edit view, left LCD. But if I go to: Event menu>Edit Name in a drumtrack, I can only edit the name of the individual druminstruments, like BD or SD, HH etc. but I can't rename the complete drumtrack. So when I go to Edit view I see in the left LCD: G3T1 OUT1 Chn.10 PA:Vel. TA:Gate, but I would like to see: G3T1 Dstation 808 PA:Vel. TA:Gate, How will I achieve this? Cheers, Roel

You're very welcome, it's the least I can do! Great such a simple connection is possible, I'll give it a try this week. Cheers! Roel

Hi Thorsten, Thanks for your reply. I thought it wouldn't be that easy. I played with the board alone to see what happens, just powering it from the 5v output of my stm32f4 board. I don't see any onboard LED's blink when I touch a sensor input, so I let it rest for now. The midio128 suggestion is a good idea, I'll try that! Can I connect the PIC based MIDIO128 V2 midi out directly through a 220 ohms resistor to the midi in of the MIDIbox NG board/ pin PA3 of the stm32f4 board? Last month I builded the Mayhem Machine, a video sequencer (see pictures in my gallery) running MidiboxNG together with Max/Msp. It was my first experience with Midibox NG and configuring it in Mios Studio. WOW I was really stunned by the ease of use, it works great!!! I did read the info a lot of times before and did some little tests, but I really need to work with a practical application to get the feel with it. I'm really impressed how you lift this Midibox platform to the next level over and over again. Your work enables a nitwit like me to create really stunning stuff! THANX!!!!! ( the Max/Msp programmer I worked with was also really impressed!) Cheers, Roel

Hi, I'm playing with Midibox NG and would like to add some touch sensors to my next project. I'm aware that they were supported by MIDIbox64 and NOT by MIDIboxNG. After searching the net I came across this little board: https://learn.adafruit.com/adafruit-cap1188-breakout/ I would add this to my MIDIbox NG but I'm not sure how to. It has I2C, ISP and outputs that go from 3V to GND when touched the corresponding input. On adafruit there are some examples but they are with Arduino, i don't know how to use them. I'll start experimenting with adding the outputs to my DIN's an see what happens, but all help/idea's are welcome!
