Benchmark Results:
The benchmark is to run TooB NAM with an A1 model to generate 100s of audio. Lower times are better.
TooB NAM has a compile-time switch that uses either the NeuralAudio NAM implementation or
the Neural Modeler Core NAM implementation.

Downloaded from Tone3000.
The model file is attached.
Compilation flags:
summaries for Mono audio adapaters.
Check PWA on windows, edge and chrome.
Make sure Pi 4 default audio device is still hidden when selecting devices!
A final solution for rate-limiting on Tone3000.
A way to force input to mono?
Tooltip on File Property Select: add to release notes.
sAFEfILEnAMES: RENAME, &C. Safe bank names?
NEW BANK
WINDOW SIZE CALCUALTIONS ARE WRONG ON LINUX HIDEF DISPLAYS.
Carla Project icons.
check reload after change of LV2 plugins.
Exactly one underrun per seek in Toob Player
json nan/inf is fatal.
- pipewire aux in?
