Hmm, well done. I've probably missed some package during my first try, it's the reason why I've downloaded the whole Qt. But now I've used your recipe on an other linux computer (x86_64), and I managed to build the OPAEditor binary without problem. The failure is maybe an incompatibility with the raspberry ARM processor. I'll try to have a look (even though I'm far from being an expert)

sudo apt-get install build-essential git qt5-default qtbase5-dev
git clone https://github.com/Marzac/OPA-Editor.git
cd OPA-Editor
qmake .
make -j 4
./OPAEditor

I've tried to mix a recording from the ym2151 shield with other music sources, and it seems the tonality is about 1 tone above the rest, that's funny.

I had something similar. What worked for me was to remove the current instrument and load a new one. Sometimes the editor got stuck and then I had to start it again. But otherwise it's very fine. I haven't tried to play several instruments together but I intend to do it.

Cool.
You can find a quick how to there:

but hmm, I see now there is no Qt installer for raspberry pi / arm. It might be quite complicated... unless you figure out how to use the qt5 version packaged in the rpi distribution...

very cool! I'll try to be there (remotely).
Just to be sure, for "normal" entries, do they have to be anonymized?

And for realtime, is it correct to "prepare" some sounds and instruments in advance?

hey, thanks. I simply did "sudo modprobe snd-virmidi" and now I have my virtual ports. Then as you said I connected the java app, my virtual keyboard and musescore (midi player / composer) to the virtual in. And the virtual out to my midi port, connected to the ym2151. It works fine.

yeah, sadly the prices have much increased the last few years sad
A friend of mine got an Amiga 1200 in very good shape for 50 € some 8 or 10 years ago. Now for the same stuff it would be around 150-200 € I guess (or even more). Recently I saw someone on leboncoin who tried to sell an Amstrad 6128 for 150 €! You just have to be patient or try ebay.

Fun fact for the 3€ DMG gameboy (which is almost like new), the week before, as I couldn't find anything at garage sales, I bought on leboncoin 1 DMG + 1 gameboy color for 35 € (but I don't regret it)

This year I got a nintendo DS (like new) for 15 €, a megadrive 1 for 35 € and a nintendo NES for 30 €

For midi an atari STF is enough. You can find them around 30 and 60 €. On local retrocomputing forums you can make good deals, some people can sell them for a fair price. The STF has the same ym2149 soundchip as the ste, but the STE is easier to record because of the RCA output (and also it can do DMA and such). STE is better of course, but not much different from STF (maxymizer works great on STF too).

@ArtyBoomshaka: on French garage sales ("vides-grenier") you can find gameboys for a cheap price, I found one for 3 € wink
You can find some in leboncoin or in real second hand shop like cash express / cash converter, for between 20 and 40 € (mostly around 30 €)

If you want midi, use atari...
You can also get a MiST fpga box which has a smaller form factor, and can do atari, amiga, c64, spectrum.... (and midi as well)

Thank you. I've tried the arduino code, and it seems to play fine. For the java application, it works for me, but I have a problem for using it with my soft keyboard (vmpk), when vmpk is on, the java controller can't use midi, and when the java controller is on, vmpk can't use the midi channel, so I can't even make a sound without external midi control. Maybe it's a problem in my configuration or a compatibility issue with Linux, so I'll test it further...

You've been very didactic Kvee, that's kind of you. I did the same for my PSU, except I wasn't careful enough and I shortcut two pins, which burned the fuse... I suggest you use a plastic cylinder around the pins (from a ball pen maybe?), that could help to isolate the outer ring and other pins.

Could you try to check the psu voltage first? (I mean voltages)
