PiMidi
I'm a complete noob when it comes to anything Midi related on the Amiga and now see that games like Blood and Dark Forces support it using a Raspberry Pi on something called PiMidi. My question is what is it and how does it work on the Amiga?

Please link to which PiMidi project you are interested in? There seem to be a few different projects with the same name.
The one that does RTP MIDI will not be possible to connect to an Amiga directly, you would need some other computer that has physical MIDI and the capability to route the MIDI data from there to RTP MIDI. The projects that have 5pin DIN connectors just hook up to an Amiga MIDI interface and work that way. The Amiga MIDI interface hooks up to the Amiga's serial port. |

You can use MT32-PI the Raspberry Pi 3 bare-metal midi emulator: https://github.com/dwhinham/mt32-pi
Then build (or buy a ready-made hat such as this https://www.arananet.net/pedidos/pro...g-raspberry-pi) to make it able to connect to your Amiga with the help of a serial-to-midi cable/ |

I didn't realise there are more than one option available for the Amiga however what btp mentions is pretty much what I'm looking for and this arananet baremetal emulator looks ideal but sadly not in stock. Are there other options or would something like this work too?

A quick search reveals that The Pi Hut has separate hats for midi in and audio out, which I very much suspect you could stack to get the same result (verify the DAC on the audio hat is supported by mt32-pi first though). |

Does the Amiga audio output need to be converted into midi output with something like this adapter before it's connected to the HAT?

You will need a serial to midi out adapter so that the midi commands that the Amiga outputs can be sent to the midi in port connected to your RPi3 with the mt32-pi software.
For all this to work the game you are interested in should support midi output for it's sound/music. Please note that there is NO such thing as automatic conversion of the Amiga sound to midi! |

Hi all,
Hoping to get some help with a MT32-pPi please, and this looked like the closest thread to post in. I purchased an Amiga MIDI interface (K12) from Amigastrore.eu but can not get any data from the K12 on the Amiga to my MT32-pi. The K12 plugs into the serial port and provides 1xMIDI IN and 1xMIDI Out 5 pin DINS. https://amigastore.eu/en/590-midi-in...for-amiga.html I am using Kickstart and OS 3.2.2.1. I have checked my serial port, it works fine with a WiiMODEMPro at 38400 Baud. I do get sound from my normal audio ports, playing a mod file for example. My Bulky-mt32-pi is starting up fine, and I have checked the config and using a known good config from the seller. I have downloaded CAMD and CAMD40 from aminet, and also the SMF datatype. I can play a .MID file from Multiview and the Piano meter from CAMD-tools shows something is playing, but still no sound and no data. Attempting to play an MT32 enabled game from WHDLoad also produces no sound. I have tried changing my serial prefs, and pumped it up to 31250 baud, no parity, no handshake, 8 bits, 1 stop bit. I can connect my MT32-Pi to a Yamaha electric piano, and it does receive data. So I think I have narrowed this to the K12 - or something I have missed on my Amiga to enable the K12? What have I missed pleased, what can I check? I have an Oscilloscope and a multimeter if anyone can tell me what to look for, I would be very grateful for the help. Thank you! |

In the mt32-pi.cfg file you can configure the output device.
# pwm: Use the headphone jack # hdmi: Use the HDMI port # i2s: Use an I2S DAC output_device = pwm Check what output you have or try to another. |

If that MT32-pi is similar to the one araranet sells (sold?) you will need a MT32_control.rom and MT32_pcm.rom file on it.

Thanks for the replies and confirming I did need to change my .cfg file to use 12s rather than the default ppm, and I do have the ROMs on the SDCard correctly, thanks.
It was the KA12 that is dead. I suspect it is looking for power from a device plugged in to the MIDI IN, and without that - does sweet FA for me. I had an AMAS in storage and plugged it in - worked perfectly, first time, and enjoying it all day. I contacted amigastore.eu, they have asked for pictures of the circuit board. meh. Will send them some pics and see what happens. The initial response was pretty poor support I felt: "Sorry, we have no experience with this device as we purchased the cable from an external manufacturer". Anyway, I am using my AMAS with the MT-32pi now, and it sounds amazing! |
