alsa.output_device

Hello,

i have a Midisport 2x2 USB Midi Interface with 2 Midi Outs HW:1,0,0 & hw:1,0,1
Is it possible to send the signal to both outputs?

Hi Dave! Thank you again for creating this program. I am trying to get the midi messages to receive on the windows side and my audio software is not receiving any notes, though I see the MIDI Device (RTPMIDI). In RTPMIDI It sees my raspberry pi with 0-1ms lag. Seems to be setup correctly. Perhaps I am not using the correct ports?

Like you have in one of your youtube videos, the port I typed in on RTPMIDI is 5006.
On the raspberry pi ravelox config file I put:

network.bind_address=2.0.0.5
network.control.port=5004
network.data.port=5005
network.local.port=5006
network.socket_interval=5000
network.max_connections=4
service.name=propsav_midi
run_as_daemon=no
daemon.pid_file=raveloxmidi.pid
logging.enabled=yes
logging.log_file=raveloxmidi.log
logging.log_level=normal
security.check=no
readonly=no
inbound_midi=/home/pi/Desktop/raveloxmidi/src/raveloxmidi.inbound
file_mode=0777

2.0.0.1 is the IP of the windows computer and 2.0.0.5 is the IP of the raspberry pi. Please advise as soon as you are available, thank you so much. Stressing out here, haha.

Ravelox on Windows, Midi Loopback

Hi there!

Is it possible to run the python code for PiMIDI on a Windows Computer and send the MIDI to a program running on the same computer? Would this require a MIDI LoopBack? Some localhost settings?

Please advise. Thank you very much for your work on this.

sending lots of messages quickly - SIGABRT

Im sending quite a lot of messages quickly, and after a while i get memory corrupt on the free() and aborts (see stack below)

ALSA Integration

I'm trying to integrate ALSA.
Following the instruction i get this from amidi -l

IO  hw:1,0,0  electribe2 sampler MIDI 1
IO  hw:2,0,0  Blofeld MIDI 1
IO  hw:3,0,0  ZOOM MS Series MIDI 1

IO  hw:4,1    Virtual Raw MIDI (16 subdevices)
IO  hw:4,2    Virtual Raw MIDI (16 subdevices)
IO  hw:4,3    Virtual Raw MIDI (16 subdevices)

so i append
alsa.output_device = hw:4,0 in config file.

when i run sudo raveloxmidi -Nd -c config i get:

Inbound MIDI

Hello,

Firstly, I LOVE your project. I have been playing around with it a lot with several Raspberry Pis here at work and it is very useful for music creation.

I am wondering if you could lend a hand in setting up inbound midi messages to pimidi from an external source? I have got outbound working great, though I would like to handle inbound and I can't find where these messages are stored or how they are handled.

Are they saved in a list to a text file? Is there a function I can use to interpret them? If not I can just check the size of the file and if it grows in size, handle the last message in the file.

Thank you so much. My email is [email protected]

modprobe snd-virmidi

I am pretty sure I have raveloxmidi properly installed. How can I tell? How do I start it?

When I run modprobe snd-virmidiI get an error modprobe: ERROR: could not insert 'modprobe snd-virmidi': Operation not permitted.

When I run ./raveloxmidi -N -d I get a bunch of data but when I run sudo amidi -l only my hardware interface is listed.
I want to send inbound_midi to my hardware interface. Is this possible?

Using 2 input devices / 2 sockets at the same time

Hello,

thank you for creating this awesome tool, I really like it.
I recently got a Launchkey 61 MK2 which works as 2 MIDI devices.
One for "InControl" Mode and the other for regular MIDI.
The problem I am facing now is, that I can't use the same address twice and from your documentation I can't see a way to get it to work with two MIDI devices in one instance.

Is there already a way to handle that and I missed it?
Is there a way to let it use the same address (but different ports ofc) again?

Thank you again for your work.

Looks like it may be Avahi / mDNS related? I have avahi and nss-mdns installed

Bug: Connection with mobile devices

Im using NetMidi with Ravelox bug having issues

If I use NetMidi to request a connection with Ravelox Midi NetMidi will show the connect for 20 seconds then the connect will disappear. When I check the debug log in Ravelox there is no records of the connection at all. NOTE: if I have Ravelox to start the request to NetMidi it works fine.

This happens with all mobile apps supporting rtpmidi. Ravelox can request the connect and it will work but if the mobile apps request the connect it will not work.

I have attached debug file and video
iphone debug file.txt

Does this work on x86 / non-arm linux?

I have been searching for a long time for a native linux solution for rtpMidi (to send/receive from iOS), and this is the most promising thing I have come across that doesn't use Java

Can this work as an rtpMidi <--> alsa converter on non-arm linux?
If so, how might someone go about using your code? =D

I'm making adistro geared at user friendly live performance and am interested if I could use this

Thanks!

use all memory then crashes once first midi message is sent

Hi,

im attempting to run raveloxmidi on a rPI3 connecting to a mac (10.14.5) over wifi
a very simple setup.. built from GitHub

alsa.input_device = hw:2,0,0
network.bind_address = 0.0.0.0
logging.enabled = yes
logging.log_level = normal

sudo raveloxmidi -N -d -c /etc/raveloxmidi.conf

it starts ok on the rPI, reporting

network.control.port = 5004
network.data.port = 5005
network.local.port = 5006
network.socket_timeout = 30
network.max_connections = 8
service.name = raveloxmidi
service.ipv4 = yes
service.ipv6 = no
run_as_daemon = no
daemon.pid_file = raveloxmidi.pid
logging.enabled = yes
logging.log_level = normal
security.check = yes
readonly = no
inbound_midi = /dev/sequencer
file_mode = 0640
discover.timeout = 5
sync.interval = 10
network.read.blocksize = 2048
alsa.input_buffer_size = 4096
config.file = /etc/raveloxmidi.conf
alsa.input_device = hw:2,0,0
network.bind_address = 0.0.0.0

and the mac sees it, and then I can connect...

viewing with 'top' on rPI, all looks good,
but as soon as i touch a key on the midi controller

the cpu % rises to 100%, and memory then rises to 100% and ravelosmidi is killed by out of memory reaper, and I can see below in dmesg

thoughts?

add ipv6 tip to the README.md

You should add the following text from https://github.com/ravelox/pimidi/tree/v0.5.5 to the file https://github.com/ravelox/pimidi/blob/master/README.md

I think it's an important note and people might miss it if it's not in the main README.md.

If you are finding that the client connecting to raveloxmidi is reporting issues trying to connect to an IPv6 address and you do NOT have IPv6 networking, you need to edit /etc/avahi/avahi-daemon.conf and set:
use-ipv6=no
publish-aaaa-on-ipv4=no
Obviously, if you want to use IPv6, both those options should be set to yes
You will need to restart Avahi for those changes to be picked up.

libasound2-dev required for building on ubuntu

If you want to build on Ubuntu 18.04.3 LTS, then in order for pimidi to work with alsa, you will also need:

sudo apt install libasound2-dev

Perhaps this could be added to the README.
Thank you for pimidi.

Connection Bug

I notice if we use the Configuration option remote.connect then we run the script it will only stay connected to the remote computer for about 10 or 20 seconds. On the remote client it will tell me that its been connected with 0ms latanecy. It will pass midi messages but will disconnect within 10 to 20 seconds.

raveloxmidi running at 100% CPU

Hi,

I’m running raveloxmidi v0.5.0. First of all, thanks for the great work!

All works very well, except that the raveloxmidi process is constantly consuming 100% of a single CPU core.

This happens with the default configuration, running it like this:

sudo raveloxmidi -N -d

(Removing the debug flag doesn’t reduce the CPU usage)

The system is a Raspberry Pi 3 running Raspbian Stretch.

When I’m running the process as a systemd service, the unit gets killed every few minutes with the following message:

Question / Segfault (core dumped) on Ubuntu 18.04

Hello

Thank you for this tool. I have a question, is there also a possibility to connect with ravelox-pimidi to rtpMIDI from Tobias Erichsen. Because the other direction it works if i let pimidi run as server on my ubuntu and initiate the connection from rtpMIDI from my Windows.

I've drawn a Diagram, and i'm quite sure your tool isnt meant to work that way, but it does https://0x8.ch/music/remote/Domain-Model-0.0.1.svg

but it would really great to have eg. a variable in the config file like

network.connect_to = 192.168.123.123

and the second thing was that it crashes then and when (Segfault)

with kind regards
Marc

It seems that -pthread is missing from the gcc call.
Looking into the Makefile tell me that PTHREAD_CFLAGS is set to -pthread while PTHREAD_LIBS is blank.

Adding -pthread flag to the end of the gcc call fix the issue.
So I guess something is badly detected, but I can't find where.

I'm on Raspbian scretch lite, fresh install of 2018.11.13 release.

build raveloxmidi ubuntu

hello,
This is exactly what I need, thanks a lot for sharing this!
I am trying to build it in ubuntu instead of raspberry, would you like to help me a little bit with this?
Thanks in advance!

SUMMARY: ThreadSanitizer: data race /home/mganss/pimidi/raveloxmidi/src/net_connection.c:419 in net_ctx_increment_seq
==================

The line numbers might be off because this was running on my development branch. applemidi_feedback.c:66 is this:

if( feedback->rtp_seq[1] >= ctx->seq )
{
	logging_printf( LOGGING_DEBUG, "applemidi_feedback_responder: Resetting journal\n" );
	net_ctx_journal_reset(ctx);
}

I'm not sure if this is the right way to go, but I think it could be fixed by pushing the test into net_ctx_journal_reset and inside a lock there plus adding a lock around the access to ctx->seq in net_ctx_increment_seq.

Failure to get socket

any ideas?

Custom Configuration File - Bind Address Problems

Hi there!

I'm trying to set up raveloxmidi on a new system using a custom config file. I tried specifying the file location with -c but it isn't working right. What is the proper syntax to use -N -d and -c?

Another attempt I've tried is just editing the raveloxmidi_config.c file to change the settings and they aren't reflecting when I run the code for some reason.

Thank you so much for developing this! It's very useful.

Problem - Windows connection: no MIDI note..

Hi Dave,
how are you?

I'm using ravelox midi with rtpMIDI.
I created an Ubuntu virtual machine to test it.

When I start raveloxmidi, the connection is successfully created, and I see the new port "raveloxmidi". I can connect "raveloxmidi" to my local session.

The problem occurs when I start the python script (note on / note off - udp_client.py), it runs OSX, but Windows does not come anything ...

What could be the problem?

Thank you very much for helping!

Add MidiClock Support

As I first saw this, I though man this is exactly what I need but then, I saw that you don't support MidiClock.
So if you could add a support for MidiClock would be super cool ;)

Anyway pretty cool project and I'm definitely looking forward to see it grow.

pimidi from pi to pi possible?

Hey Dave,
thank you very much for your work on pimidi!
I tested raveloxmidi with a pi being connected to Ableton Live via the mac osx midi network studio (on Ethernet). This worked.
But for my project I would like to connect two Raspberry Pis via Ethernet for midi communication. Is there any way I could achieve this using raveloxmidi?
In the midi network studio on mac osx we have the gui to create a midi network session and connect to participants (-> the raveloxmidi instance). But how would I instantiate such a session on a raspberry pi and connect to the other raspberry pi?

I couldn't find an email address of yours, so I just created a new issue to contact you. If you prefer to communicate another way, please let me know. My email address is [email protected].
Hope to hear from you, with best regards
Jakob

Could you provide all needed prerequisites and step by step procedure for build and run your package?

Disconnection happen too often

while my Pi is still connected to the network, I got this pop up from the Audio and Midi Settings :

And it doesn't work anymore until I manually reconnect it.

How to debug this disconnection to fix it ? (my network setup might be involved)

How to integrate with ALSA midi?

Is there a way to integrate this with ALSA MIDI? I'd love to use this as a MIDI interface within Supercollider.

Edit: It looks like this would be an ideal case for ALSA RawMIDI: http://www.alsa-project.org/~tiwai/writing-an-alsa-driver/ch09.html

rtpMIDI Device Name Changed

Hi Dave,

I changed the name of the computer which rtpMIDI runs on and now it fails to receive MIDI Messages from the Raspberry Pi. I can see in rtpMIDI it has a Participant named networkmidi @ 0ms lag though inside of my midi software it is not receiving messages. Have you seen this before?

Thank you.

Infinite loop in the arg parsing of raveloxmidi_config.c

My knowledge of command line linux programming is limited, but a few fprintf's and commenting out the while(1) loop in config_init() leads me to believe that that while loop gets stuck in an infinite loop under normal operation. For my own purposes, I just uncommented the config statements that I wanted and the program progresses properly.

Wish I could provide the actual solution though...

Possible to build as a dynamic library?

I would like to interface your code to a Java application (a PI sample player interfaced to an old set of Hammond Organ pedals. I want to be able to send out midi via rtp/WIFI as pedals are pressed. To do this, I can write a Java JNI interface to a C/C++ dynamic library. Receive midi would also be useful of course. Your code does all of this so I just need it to exist as a library instead of a daemon.

Is there an easy way to configure the build process to do this? If not, could you give me some pointers to where I could educate myself?

inbound midi

Hello Dave,

I have successfully installed raveloxmidi and have the raspberry pi sending midi notes and receiving on the Mac. One problem I have is that I tried specifying different locations but the inbound midi would never be logged, I am receiving the error:

[1540446274] WARNING: net_socket_setup: Unable to open "/home/pi/pishare/m.txt" : No such file or directory

My goal is to receive the midi messages (Program change and CC) being sent from mac and 'forward' them to the control external guitar effects processor via a usb midi cable.

Can you shed some lights on how can I achieve this?

Let me see if I undestood. (PiMidi -> ipad)

Can I run Pimidi in my raspberry PI 3 as a rtpMidi server (like I do in windows with RTPmidi program) and control things in amplitube or other guitar amp simulator that uses apple core midi features ?

Receive midi message from mac to pi

I have installed the script and tested it. So far I have been able to connect to the mac. I like to know once connected is there any way for the mac to send a midi message to your program.

basically I have connected to the mac. now the mac is sending midi messages however pimidi is not receiving the messages.

BUG (remote.control_use) Issue #47 is back with version 0.8.99

Having issues with using remote.control_use feature. I noticed that there was a new version of the software after doing the following

git clone -b experimental https://github.com/ravelox/pimidi.git

It downloads version 0.8.99.

It looks like remote.control_use feature is not recognized. If I click on the download like directly from github page then it downloads the working version. Is there something I am doing wrong or has that feature not been implemented yet for the new version?

Not running on read only file system

ERROR: Unable to write pid to raveloxmidi.pid: Read-only file system

Please provide work around...

Thanks in advance

rtpmidi packages input on raveloxmidi problems

Hello Dave,
I open a new ticket to ask you information.

I have tried to send a MIDI note from a controller (from a remote IP in wifi network) to raveloxmidi, to read the data back (for example from a sequencer).
On raveloxmidi logs I read: Dates (0x80) on socket (1) from (192.168.0.4:5008)

I added some debugging prints within raveloxmidi.

If I die a normal MIDI note (running the python script), I get:
DEBUG: Midi Packet: aa
DEBUG: Midi Packet: 96
DEBUG: Midi Packet: 3c
DEBUG: Midi Packet: 7f

While if I get a midi note to an external controller, I get:
DEBUG: Midi Packet: 80
DEBUG: Midi Packet: 61
DEBUG: Midi Packet: 2a
DEBUG: Midi Packet: 82

We seem incorrect data ..

According to you, we can integrate ravelox midi adding this feature?
You may give us directions?

Thank you so much!
Alessio

cc data?

One thing I wasn't sure about from the readme is, can ravelox send cc data as well as note data? I don't see why it wouldn't but just wanted to check

Sysex file crashes ravelox

Hi,

as a test, I tried to send a sysex file to ravelox, which emits a segmentation fault. I just compiled a fresh ravelox binary from this repository.

The sysex file I've used is from here: http://host.mtnsys.com:81/faq-fcb/ExampleSysexFiles.htm named Beh Firmware Blank Sysex.syx. I've used Midi-OX to send it to my local rtpMIDI port.

The last few lines prior the segmentation fault are:

Multiple instances of raveloxmidi

Hello Dave, do you think you can start two instances of raveloxmidi on two different ports?
In this way, for example, you could control the sequencer and also a plugin.

Thank you so much for your help.

My configuration:

service.name = led-pi
alsa.output_device = hw:0,0,0
logging.log_level = debug

Command line:

sudo raveloxmidi -N -d -c /etc/raveloxmidi.conf

Being able to receiving MIDI clock information would be very useful for me. Is this maybe an easy fix?

Still having issues with not responding to the connection request

Hey ravelox

I'm still getting those having issues with not responding to the connection request when trying to connect.

I did follow these instructions, but still no luck

Not sure if this is beacause of Raspi internal MIDI routing/wiring

Hi Dave,

First of all, your work looks very promising.

I have successfully installed Raveloxmidi as per Readme.md and successfully tested the communication between Raspi and Apple MIDI network in MacBook Pro including ./note_send.py . Everything is looking good except for ,I assume, communication between Hareware MIDI input signal and Raveloxmidi. Raveloxmidi is failed to receive Note on/off event from MIDI keyboard so it can’t broadcast MIDI event to other computer in the network.

Here is my setup

MIDI Keyboard (OP-1) is connected to RPi Moel B+
MacBook Pro shares the same WiFi network with RPi

Below is what I have tested so far after installing Raveloxmidi.

I ran Raveloxmidi -Nd So that MacBook Pro can see “Raveloxmidi” in Audio MIDI Setup
I successfully established connection between MacBook Pro and Raveloxmidi, the log in RPi’s terminal also confirms MBP IP address.
I sent MIDI signal using ./note_send.py and ./send_100.py From RPi to Logic Pro X in MBP. Logic Pro X nicely returns the sound of middle C. It was also able to record MIDI C note from the test scripts.
In RPi, I checked aconnect -io To see if MIDI keyboard is registered in the list, which it did.
In RPi, i ran aseqdump -p 20:0 To see if RPi can pick up any MIDI event such as note on/ff on a particular pitch which it did absolutely precisely.

Still I can’t forward the MIDI signal picked up by RPi from Hardware MIDI Keyboard to MBP. So I assume that MIDI wiring in RPi can’t find Raveloxmidi as the final destination. Have you encounter this before? Any suggestion is welcomed. Thanks

Very nice work by the way.

midi ports not exposed or I dont know how

Hi,

I got raveloxmidi up and running, made a config file and now I can connect to the rtpMIDI session running on my windows laptop. (in the terminal output, after starting the program, it just waits on a blank line, there's no feedback messages to see the connection is made from the linux side)

But while on windows, from my daw the session is selectable as midi device, on linux this does not happen. I've checked in daw applications and in jack connection manager cadence with claudia, there's not raveloxmidi device or port to be found anywhere.

Am I missing something? A user manual containing some use case examples would be very welcome for this.

Cannot read sent data to raspberry pi

Hi Dave! Thank you for the software.
I am trying to send midi packets from a PC to the raspberry pi, the opposite way in which you planned your drum kit. I want to read the midi note arriving to the raspberry and then flash some lights with the GPIO pins.
The issue is that altought I succesfully built and executed raveloxmidi, I cannot read the port in which packets arrive.

I tried the following python script:

Import socket
Import struct

host='localhost'
port=5006

s=socket.socket(socket.AF_INET, socket_DGRAM)
s.connect((host,port))
print(s.recv(1024))
s.close

Nothing happens after s.recv.... it seems no data is read!
Can you help me with this please?

Thank you Dave
Cheers, Tom

Inbound Midi File Type

Hello Dave,

Thank you again for creating this amazing software for us! I am trying to interpret the inbound midi file. I have it saving to midi_inbound.txt on our Raspberry Pi Desktop. When I try opening the file in a text editor, it shows Question Marks inside of Diamond icons. When I try reading it with python, it shows the following:

Traceback (most recent call last):
