rppicomidi / midi2usbhost Goto Github PK

Considering that there is a Feather with integrated USB host, do you think it could be used for this project? This way there would be no need to have to use two Pico's... right?

It would be very interesting to add RTP MIDI capability to this project for MIDI output over WiFi using the Raspberry Pi Pico W

Hi 👋
I was trying to compile your code on a windows 10 with
vs code but I was not able find this file anywhere in your code (#include"class/midi/midi_host.h") can you please guide me about this issue. I have old m audio keystudio 49 that doesn't connects to Cubasis 3 but works fine with FL studio mobile on the same phone. Thanks in advance. I am getting the same error as described by fadh3r please help

Hi.
First of all, great product. This was exactly what I was looking for.
I got this to work without any issues when I connected my Launchkey 37. The midi packages was sent to my midi monitor just the same as i played them.

But when I connect my Launchpad X (mk3) I behaves weird.
When I press a key, my rpipico sends the correct midi info, but when I release it, the rpipico sends the last midi message again.
This behavior continues 15 times (15 note on, 15 note off). And then the rpipico bursts out messages.
It also falls behind as if the rpipico keeps the last message.

How can I fix this?
Is there some buffer size I can change?
Is there a way to clear the buffer so it doesn't keep the last message?

Hi!
Not really an issue but arduino-pico, tinyUSB and Adafruit-tinyUSB just got updated to oficially support USB hosting with PIO on the RP2040.
Maybe that can be a shortcut to get MIDI hosting working.

Hi,

building the executable t is proving a challenge as I have very little experience of C++ on the raspberry pico.

can you upload the .UF2 file to GitHub as I am sure that I am not the only one that would just like to download it and try it without having to go through the build process.

Great project btw.

A lot of Synths and all modular systems use a 1V/octave control voltage for pitch, and a gate signal (low/high = note off/on). It would be great to be able to use this project to control such synths or add CV/Gate outputs to MIDI keyboards. This can be done by PWM and filters or a DAC such as the MCP4725 (I2C) for a better signal. in general, a semitone is 83.33 milivolts (0.08333 V)

When using a Novation 24SL MKII for example, which presents itself as a 4 virtual cable device, the device will not work and report:

WARN: starting new transfer on already active ep 0 in
WARN: startassertion "!(buf_ctrl & USB_BUF_CTRL_FULL)" failed: file "/home/xxx/dev/pico-sdk/lib/tinyusb/src/portable/raspberrypi/rp2040/rp2040_usb.c", line 219, function: sync_ep_buffer

Hello everybody, I'm new to Pico world, that project looks like the one for me but for a thing, I need to send midi messages on a guitar pedalboard that uses usb type c but only works as a device. Would I be able to interact with it just sending midi signals with this code? I don't need to translate from din pins on UART, but just be able to send CCs and PCs over usb but without setting up a midi software on Pc. As I know already all the messages I need to sent, would be possible to just setup a midi host over the native usb of the Pico?

I have a pimoroni lipo Pico which runs off of battery. This frees up the USB-C port. Is it possible for me to modify this project to send over usb? Apologies for the "issue".

@rppicomidi thanks for sharing your code!
I now have a problem compiling midi2usbhost. Ihave done the setup according to the README.md.
Arduino IDE 1.8.20
MIDI Library 5.0.2 (also tried 4.3.1)
Raspberry PI Pico/RP2040 package 3.8.1.
All other libraries -- latest versions available.
Generic RP2040 selected (tried Feather, Raspberry Pi Pico, but no luck)
I get the following error:

midi2usbhost:51:66: error: 'MidiHostSettings' was not declared in this scope
   51 | MidiInterface<SerialMIDI<HardwareSerial, DefaultSerialSettings>, MidiHostSettings> DINmidi((SerialMIDI<HardwareSerial, DefaultSerialSettings>&)serialDINmidi);
      |                                                                  ^~~~~~~~~~~~~~~~

Please, help with this issue.

Hey,

I am the guy behind the RP2040 based USB MIDI host and I am going to release it soon.
My plan is to make the firmware open, and I was thinking for compatibility reasons and community friendlyness,
it would be nice to base it on the midi2usbhost firmware.

@rppicomidi I am happy to send you a device if you would like one.
It is powered by USB-C, has TRS-A MIDI In and Out, a USB MUX, Power switch to external device via MOSFET and much more. Wriite me an E-Mail to midihost (at) datanoise.org

The Raspberry Pico and my boards have the GPIO24 which can detect if VBUS is coming from USB or not. Therefore, it can detect if the device is used as USB Host or Device.

Would be great to see dual mode / switched mode depending on the state of GPIO24.

Hi. Sorry for reporting an issue but I don't see a discussion option.
I am trying to build a midi controller so that I can send midi commands to my NUX MG-300 guitar processor. I am currently using Arduino Uno for testing purposes and I have managed to send and receive messages (cc and sysex) going through PC. The problem is that arduino uno cannot be a usb host so I cannot connect MG-300 directly to it. There is an option of using a usb host shield but it is not cost effective and I think I will need more resources to implement everything that I envisioned.
I think you mentioned here hathach/tinyusb#1152 that you have an issue receiving messages from usb device. Is this resolved?
Do you think that this project can be modified so that I can send and receive MIDI messages to the MG-300?
I don't need the "old school MIDI IN and MIDI OUT" if it makes any difference.

Hello.
I can capture midi notes with velocity and modulation from my arturia microlab. but I the pitch bend messages, as soon as I take my hands of the pitch bend strip, seem to freeze my pico.
Is this an know issue?

It works beautifully! but I'm getting an error when I connect a midi device that has two virtual cables, sometimes it detects the device after 10 secs then it unmount the device.

Is the a way to get it work with a multicable device? I have only tried with a keystation mk3 it has 2 virtual cables.
when I plug a simple 1 virtual cable it works great.

Thanks
