Hi Marcel, welcome abroad!
I just want to say high to you!!!, unfortunately I can't help you with this problem, as I'm working on MBCV2 with a LPC board, see pic.
It's been some time since I last played with it. I started to addapt the Lemur template for my Samsung Galaxy S5 and came quite far. I have to dive in it again.
I heard good stuff about your DIY CNC machine, I'm really curious!
Sorry for interupting your question/problem, good luck with your LCD!
Cheers,
Roel

Hi AVLG,
Cool module indeed!
2 all:
Last month I made 2 samplebanks for my sample player, 2 octaves of accordion notes, 2 octaves of ContraBass nootes and 5 octaves of piano notes.
The accordion notes sounded quite well but the piano distorted a lot when playing polyphony notes. So I tried again and normalized the piano sounds with -6dB, but they still distort really fast compared to the accordion sounds, while the accordion sounds are a lot louder.
The only thing I can think of is that the piano sounds are far more clean and harsh sounds compared to the accordion, wich are a lot fuzzier, so you hear the distortion much better with piano sounds.
For now I play polyphony piano sounds with low level velocity and it works acceptable, but maybe you have some hints to get more volume out of the piano sounds without distortion.
And because it was quite some work to set up these sound banks I thought it would be a nice idea to share the files here so you can try them yourselves. Maybe you want to share your sounds also with us. I would love to try those melotron sounds or drumkits.

Hi welcome!
MIDIbox is a supurb platform indeed with a great sequencer. I don't wanna start about the possibilities or your questions, cause others are way better in that. Only thing: "I also implented musical scales. And a "notefilter" that only allows notes to be used that are in the chosen scale!"That's implemented in Seq4 as well and it's called FTS (force to scale)
I just want to show you this movie from a MIDIbox I made witch has a sliders that are controlling note values. SEE HERE
Cheers,

Couldn't you just save a "tuning" track, and then load/play when you want to tune up?
Of course you could, that's how I do it right now. But this needs tweeking everytime,.. like setting witch output,... if you want to hear 2 or more synths to listen to the drifting of VCO's you need more tracks. And with this 'tuning tracks' you have to run the sequencer, it sends out all other kind of information, Ok.. you can mute everything except for the tuning track etcetc . In the end it's quite a hassle. It's much easier to stop the sequencer and send a C3 note-on command to all machines. And hearing all those drifting/droning oscillators plaing just a C3 is quite impressive, I would love this feature.
-
Yes, I also have a feature request!!!
In history I builded a P3 sequencer, from Collin from sequentix, and this had a special 'tune' knob. It was a really handy knob witch I used a lot with my old analoge synths. When you hit it it sends a C3 note-on midi command on all outputs, and when you hit it again it sends the corresponding note-off command, I would love such a button cause it eliminates a technical setup step, really easy tuning!

I would be interested in some boards at such a price.

Ik heb het in het verleden hier gekocht. Ze deden toen alleen verzenden vanaf 3 verpakkingseenheden?! Ik had toevallig een vriend in de buurt die het voor me op gehaald heeft.

Hi Shuriken,
If I click on Manage Image I only see; Edit details. If I click on that I can delete the thumbnail, but the picture is still there, even after saving. I don't see an option to delete the picture.
It's not a problem for now, but I remember I had this problem before, and I'm unsure if I solved it. I just don't understand.
-
I've a similar issue, is it possible to delete a single image from the gallery?

Thanx, it's great work to do, but quite hard sometimes to keep everything going. The bus is 40 years old and we do all maintenance ourselves, we get a lot of energy from the kids!!!

Hi Mathis,
It took a long time to succeed this indeed. The idea started in 2011, I made a simple MIDIbox with an Ikea cabinet and showed it to a cultural/educational company. It was just a mixer, you opened a drawer and a sound came out, see here. The company was really interested and asked my to build one for them so schools could use it. We descided it should do more than just mixing some sounds, so we started brainstorming and came with the concept of improvising with pentatonic scales. Then they came with the woodworking man, great guy, but all this getting together with different people took long time. Everybody busy, etc, so there were months even years, the project lay down.
And there were several technical difficulties to sort out. Non tecnical teachers should be able to pick up the cabinet, take it to school, plug in power and play with it. The machine must start up,and start up Ableton etc, without any errors. What if kids pull out the plug and put it in again. In the end that was the hardest part for me, cause I'm no special computer expert and no programmer at all, and it's quite an unusual situation. But with different fora I managed this problem.
I also builded some max4live devices and that was also completely new for me. In the end it was a lot of work, but I learned a lot, and it's great stuff to do!
For the speakers I didn't put any effort into the design. I just searched second hand sites for 'flat-speakers' and found Magnat S-10 speakers. They were flat, sounded good and had enough power to give the sound body. It worked out well, only some resonating thrills on low sounds, but that's just the woodwork.

Hi TK,
It's been more than a year but in the meantime I tried your suggestion of using MIDIO128 for touch sensors and it worked out really great. I wanted to let you know earlier, but I also wanted to show it. It took some time to finish my idea but here's the video: https://youtu.be/_6IIwa3SZ0Q
Again your solution/suggestion was great and this whole cabinet thing wouldn't be born without your MIDIbox platform, you're my hero! Thanx!
Cheers,
Roel

Hi there,
One of my biggest project so far: the Klankkast! (dutch for resonator box) It's just a drawing cabinet with a simple HP computer in side, running Ableton with some Max4Live stuff controlled by Midibox!
It's an educational instrument for schoolkids to start improvising. I builded it togher with Martijn Koomen (he did all the wonderfull woodwork) for an educational institute in the south of the Netherlands.
It's a MIDIbox NG (stm32F4) for all analog input, sliders and pots, and the touch tips are connected to a Core8 running MIDIO128 V2. Special thanks again for TK for pointing me in this direction!!!
Here's my first video of the cabinet!
Cheers and enjoy watching!

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!

You would like to see the four MIDI ports (IN and OUT) over RTP-MIDI (like getting a kind of RTP-MIDI interface with four ports?) directly over RTP-MIDI?
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.
If it's the case, the current firmware is not intended to work directly in this way. The RTP-MIDI interface is an "autonomous" MIDI interface, like the USB one and like the four DIN ports. In other terms, you have six MIDI ports, without correlation between them (if you prefer, what happens on one port has no direct effect on any other port)If you want to get data from RTP-MIDI and forward them to a DIN port, you have to tell it to MIOS. In other terms, you have to write a "routing" software. MIOS will not route directly MIDI data from one port to another one (whatever the port type by the way)
As far as I remember, the demo code written by Thorsten was doing that on one port (I do not have the source code in front of me, I can check later if you want). I think it was getting everything from RTP-MIDI and send it to DIN port 1, and vice versa.
Benoit
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 4It 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!
Mios8 rebooting after query
in Testing/Troubleshooting
Posted
Hi,
My Mios8 based MIDIclockbox cannot connect to MIOS Studio. As soon as I want to contact te Core by hitting the query button, the clockbox starts rebooting. My midi interface is working correctly, and the MIDI in of clockbox also, cause it slaves perfectly. I made some changes to the code I would like to trie, but before opening the maschine I want to ask here if somebody has an idea to fix it.
