Software for Fender Mustang Amps.

Plug

[GitHub] [GitLab]

Software for Fender Mustang Amps. This is a fork of piorekf's Plug.

Please see Contributing for how to contribute to this project.

Requirements

• Qt6
• libusb-1.0

Building

Building and testing is done through CMake:

mkdir build && cd build
cmake ..
make
make unittest

Installation

CMake will install the application and udev rules using:

make install

The udev rule allows the USB access without root for the users of the plugdev group.

Libusb Logging

Debug message logging of libusb can be controlled by the LIBUSB_DEBUG variable (0: None, 1: Error, 2: Warning, 3: Info, 4: Debug).

plug's Issues

Loading effects from amp or file does not preserve the position

Loading from a Mustang amp

In decodeEffectsFromData(), effects in Position::input and Position::effectsLoop collide.

plug/src/com/PacketSerializer.cpp

Lines 182 to 183 in 8d93d21

	const auto slot = payload.getSlot() % 4;
	effects[slot].fx_slot = slot;

When two effects are in a same slot number(=POS%4), each of Position::input and Position::effectsLoop, the one in the later packet (in the order of stompbox, modulation, delay, reverb) will erase the other.

This occurs possibly in the preset created with Fender Fuse, and so in the built-in V2 presets "Amin 3rds Solo", "Angry Rodent", "Purple Fuzz" (maybe different POS value from V1's?).
Those are treated as valid presets when loaded at Mustang I V2.

Loading from a file

In parseFX(), fx_slot is reset as its rank.
This will effectively make a preset safe for decodeEffectsFromData(), but at the loss of exact user-defined position.

plug/src/ui/loadfromfile.cpp

Lines 221 to 232 in 8d93d21

	const int position = m_xml->attributes().value("POS").toString().toInt();
	if (position > 3)
	{
	m_fx_settings[x].position = Position::effectsLoop;
	}
	else
	{
	m_fx_settings[x].position = Position::input;
	}
	fx_slots[position] = x + 1;

plug/src/ui/loadfromfile.cpp

Lines 424 to 429 in 8d93d21

	for (int i = 0, j = 0; i < 8; ++i)
	{
	if (fx_slots[i] != 0)
	{
	m_fx_settings[fx_slots[i] - 1].fx_slot = static_cast<std::uint8_t>(j);
	++j;

Fender Mustang 2 - Core Dumped

I have installed plug from the AUR and while the application will start when there is no amp connected, once connected the application will crash with the following:

[~]$ plug
/usr/include/c++/12.1.0/bits/stl_vector.h:1142: std::vector<_Tp, _Alloc>::const_reference std::vector<_Tp, _Alloc>::operator const [with _Tp = std::__cxx11::basic_string; _Alloc = std::allocator<std::__cxx11::basic_string >; const_reference = const std::__cxx11::basic_string&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.
Aborted (core dumped)

The amp appears to be well detected as per the following in dmesg:

[ 99.580968] usb 1-10: new full-speed USB device number 6 using xhci_hcd

It is even detected by pipewire and detected as Mustang I/II.

Fender G-DEC 30 Compatiblity

Does anyone know if this program will work with a Fender G-DEC 30 (First Generation Amp)?

Compiling fails in Manjaro

I'm trying to compile Plug 1.4.1 in Manjaro, but I'm getting the following error after running make:

From the error, I can't find anything obvious, so I'd like to see if anyone would have a clue of what's wrong.

Mustang V v2 amp not recognized.

Plug v1.2.1 identifies the amp and works correctly, but this version does not. I'm not sure what the difference is. If you need any info from the Mustang V v2, just let me know and i'll get it.

Cmake fails due to Gtest dependency on Ubuntu Studio 22.04

The "cmake .." command fails due to Gtest dependency on Ubuntu Studio 22.04

CMake Error at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find GTest (missing: GTest_Mock_INCLUDE_DIR GTest_Mock_LIBRARY)
Call Stack (most recent call first):

  cmake/FindGTest.cmake:33 (find_package_handle_standard_args)
  test/CMakeLists.txt:1 (find_package)

I installed libgtest-dev, build the libraries (got 2 *.a files) and moved them to /usr/lib but cmake still fails as above. Any ideas? Is it maybe possible to build without the dependency to Gtest? Thanks in advance!

MacOS compilation

Hello.

I'm trying to compile this on Mac (I know this is meant for Linux, but I believe at least I could get the application itself compiled even if it later has issues connecting to the amp).

Even though I have installed qt5, libusb-1.0 and googletest I'm getting fatal errors about libusb-1.0 not being found.

Here's the output of cmake:

cmake ..

It seems to find libusb (installed via Homebrew) yet on the make part it doesn't seem to link it:

fatal error: 'libusb-1.0/libusb.h' file not found

I've tried manually editing all files in /src/com which have a libusb #include and swapping them to point to my /usr/local/Cellar/libusb/1.0.26/ libusb.h file yet it seems than it still shows an error when compiling the LibUsbCompat.cpp file, even though it doesn't seem to contain any libusb.h includes.

I'm also getting a ton of errors about old-style-casting and unsigned-conversions, which I've ignored using make -i

Am I missing something? Thank you.

Fender Bronco 40 support?

Hello offa,

I have a Fender Bronco 40 amp which from what I understand is very similar to the Mustang series, just with different modeling presets for bass. (Fender Bronco 40 Manual)
It used to be controllable with the Fuse Silverlight-app from Fender.

I managed to build Plug v1.4.3 and the connection fails with the error message
ERROR: Invalid amp id: 239

This error changes depending on the position of the amp selection knob. It has 8 positions and for my setup it produces the ids 171, 0, 0, 244, 239, 219, 219, 219.

Here is the output from dmesg:

Sadly, I lack the C++ skills to look into this but if the Bronco is as similar to the Mustang as I suspect then making Plug compatible with the Bronco should be doable. If someone is interested I will try to help as good as I can.

Super Champ XD

Question: does the this work with the Super Champ XD amp?

Mustang GT 40: No device found

I'm trying to make plug work with my Mustang GT 40.

I took to ownership of the AUR package for this plugin as the previous versions did not compile anymore.

I'm using version 1.4.5.

Is there any successful attempt by someone fro this amp ?

Feb 26 08:26:21 tuxedo2 kernel: usb 1-2: new high-speed USB device number 8 using xhci_hcd
Feb 26 08:26:21 tuxedo2 kernel: usb 1-2: New USB device found, idVendor=1ed8, idProduct=0032, bcdDevice= 4.01
Feb 26 08:26:21 tuxedo2 kernel: usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
Feb 26 08:26:21 tuxedo2 kernel: usb 1-2: Product: Fender Mustang-GT USB Audio
Feb 26 08:26:21 tuxedo2 kernel: usb 1-2: Manufacturer: FMIC

Seems that the amp is seen by the system. I can use it as an audio device.

I don't see anything useful here.

Is there something I can try to make this work ?

FTBFS GCC 13

FTBFS GCC 13.

Fix is to add the following to include/com/Packet.h

#include <cstdint>

udev rules installed incorrectly under /usr/lib64/udev

${CMAKE_INSTALL_LIBDIR} expands to /usr/lib64 making the udev rules installed incorrectly, the proper path for udev rules is /usr/lib/udev/rules.d (https://github.com/offa/plug/blob/master/cmake/Install.cmake#L5). Previously it was possible to set the correct path via PLUG_UDEV_RULE_PATH, but such variable doesn't exist in the project's cmake files any more.

Fender Rumble LT 25 support?

I do know this project is for the Mustang amps, but I was wondering if the bass amp support was ever considered.

At the moment I still do not own the bass amp, but I wanted to check whether anyone using it with Linux, when I found this project.
I know it is wishful thinking, but I hope that it may have the same or very similar hardware in respect of the connectivity and I could use it under Linux.

Thanks in advance,

On Void Linux.
Edit: The Amp is a Mustang 1 V.2.
build passed the unittests.
I checked the udev rules, the group exists and the user is part of it, and the amp seems to be recognized by the laptop.

Did a preset factory reset on the amp, did not help.
I don't know what to do for further troubleshooting. Is there a way to query the preset values on the amp?
Edit: I only am at the place with the amp at weekends
I haven't tried the "old" https://bitbucket.org/piorekf/plug/ on this particular installation yet.
