A port of Steven Atkinson's Neural Amp Modeler to LV2.
|
|
|
|
TooB Neural Amp Modeler uses uploadable .nam model files. Download .nam model files from http://tone3000.com, and then load them into TooB Neural Amp Modeler.
|
|
|
|
The TONE3000 website contains a huge collection of community-developed amp models that can be used with TooB Neural Amp Modeler. You can also use .nam models from
|
|
other sources. Using TONE3000 models with TooB Neural Amp Modeler is a two-step process. First, download model files to your local system using a
|
|
web browser. Then upload the model files to the PiPedal server using the PiPedal web interface. You can find an "Upload" button in
|
|
the file browser when you click on the "Model" control in the PiPedal web interface.
|
|
|
|
|
|
If you are not using PiPedal, just click on the Model control, and use the file browser to select the .nam file directly on your local system.
|
|
|
|
TooB Neural Amp Modeler supports a much wider range of amp models than ToobML, but usually uses more CPU.
|
|
You will need at least a Pi 4 to use Toob Neural Amp Modeler, and you may need to increase your audio buffer sizes to prevent overruns.
|
|
If you are having trouble with CPU usage, tone3000.com does contain some smaller amp models. Search for the "feather" tag to find
|
|
models that use less CPU. Generally, you can use up to three NAM models at once in a given preset on a Pi 4, and up to 5 MAM models
|
|
simultaneously on a Pi 5. N100 micro PCs could presumably do even better. However, exact CPU use varies depending on the complexity of the amp models you are using.
|
|
Users have reported success using NAM on Raspberry Pi 3 devices, but this is not recommended (or really supported), as CPU usage is very high on a Raspberry Pi 3.
|
|
If you are interested in profiling your own amps and effect pedals, please visit https://www.tone3000.com/capture
|
|
|
|
When the Threaded control is on, neural amp modelling calculations are run on a separate thread from the
|
|
real-time audio thread. This introduces one extra audio buffer of latency, but allows the plugin to make full
|
|
use of all availble processor cores when running more than one instance of TooB Neural Amp Modeler. As a result,
|
|
you can run more instances of TooB Neural Amp Modeler than you ordinarily could. On a Pi 5, you can run up to 8
|
|
instances of TooB Neural Amp Modeler in a single preset (as opposed to four or five), and up to 5 instances of TooB
|
|
Neural Amp Modeler (as opposed to two or three).
|
|
|
|
You need to check that the PiPedal server's CPU is not temperature throttling
|
|
when using this feature. If the CPU temperature exceeds 80 degrees Celcius on a Raspberry Pi, the CPU clock rate is reduced, and
|
|
the performance of the plugins will be affected. Having a good heat sink, or active cooling system is recommended when using this feature.
|
|
PiPedal displays the current CPU temperature in a status message at the bottom of the display (unless you've turned
|
|
that off in settings), and also displays the current CPU temperature in the status message found at the top
|
|
of the Settings page. The exact temperature at which the CPU starts to throttle varies from computer to computer. If
|
|
you are running on a system that is not a Raspberry Pi, please consult your manufacturer's help documentation
|
|
to find out what temperature heat throttling starts at on your particular computer, if you really need to know
|
|
what the threshold is; but the effect on performance is pretty obvious when heat throttling does start.
|
|
|
|
Note that heat throttling is done to protect your processor from permanent damage due to overheating; but there's no real risk of actual
|
|
damage, since heat throttling thresholds are set well below the point at which damage occurs.
|
|
|
|
TooB Neural Amp Modeler contains code optimizations that allow use of a third model on Raspberry PI 4 devices. These optimizations
|
|
were offered to the upstream NAM project, but we recommended that they not be merged into upstream sources, because they
|
|
significantly affect maintainability of the codebase. and the performance increase they provide (about 30%) is really only
|
|
relevant on Raspberry PI 4-class devices. If you are interested in these optimizations, they have been published in ToobAmp
|
|
project sources on GitHub.
|
|
|
|
TooB Neural Amp Modeler uses code from the NeuralAmp Modeler Core project (https://www.neuralampmodeler.com/). The TooB team wishes
|
|
to express gratitude to Steven Atkinson for making this revolutionary technology available as open-source code. This is groundbreaking
|
|
technology that changes everything; and work that would be impossible to replicate without the work that Steven has done.
