      Nice build! The difference between an unbuffered (LoZ, under 100k) and bufferred input (>300k-1M) won't be very drastic, usually it's the top end where various overtones live. With clean sound it might be only slightly noticeable. With...

      Version with Delay requires PSRAM, although you can change it using the delay constructor. Default settings are 400ms in RAM2. I've set it to 1sec in PSRAM: AudioEffectDelayStereo_F32 echo=AudioEffectDelayStereo_F32(1000, true); // 1 sec...

      Yes, delay and Reaper JS plugin are in. I have changed the signal path a bit. The amp sim is mono, but i made the component to work a 2xmono one, summing the L+R inputs when on and sending the same signal to L+R output. However, when bypassed...

      Pio replied to the thread teensy control of Reaper?.
      If you enable a track recording and set the Input to MIDI >> Teensy >> Channel (or all channels) you should be able to see a midi comm indicator (yellow square blinking in the default theme). In Preferences/MIDI Devices, the Teensy Input should...

      main.cpp is the main sketch, like *.ino file. The difference is you have to declare all functions before using them just as with regular c/c++ programming. To add more controls via the web interface, using the codec input level as an example: 1...

      I played a bit with the Reaper's JS plugin engine. The new Amp Modeler example will include a JS controller plugin, doing pretty much the same as the html+webMDI, but with automation, MIDI clock sync and all the audio tools a DAW provides.

      What problems did you encounter with the PlatformIO? I have just tested a fresh install of VScode + PIO on Win10, cloned project repo installed all the libraries and compiled fine. There has been changes to the main library, clicking build does...

      Delay is available in the library repo. No example yet, still testing it. Lots of fun! This is the complete amp modeler with delay, reverb, IR cab sim. Delay uses 1sec buffers in extmem (PSRAM on Teensy4.1). https://streamable.com/9wgemt

      I tried, but failed for now. After getting all the path and includes correct Arduino somehow puts a lot of code into RAM1, exceeding the limit. No problems with Platformio.

      The constructor takes a variable, which is the max delay time in ms and also a bool that says where to put the buffers. Default is RAM2, optional PSRAM. The latter do use more CPU as the RAM2 version. There are 4 buffers in a stereo pingpong...

      Just implemented a new tap_tempo function which can be called via MIDI clock callback, footswitch or something else. Here is a short sample of delay synced to a drum track with MIDI clock sent via USB: Another interesting feature is if just a...

      There is no better feedback than a piece of beautiful music with the code working somewhere inside it :) Thank you! I do have a nice stereo ping pong modulated delay in the works, hope to post it here soon. Not a reverb, but a time based effect...

      Yes, i know about tonehunt, however the NAM models are not compatible with this version of the component. IR cabsim can be bypassed or just imply removed. There is an EQ built into the SGTL5000 codec used on the TeensyAudioAdaptor. Just a matter...

      Amp Modeler example project is available here: https://github.com/hexeguitar/hexefx_audiolib_F32_examples/tree/main/NeuralAmpModeler For now PlarformIO only.

      Yes, the signal chain used in that video was: I2S->NoiseGate->AmpModeler->EQ->SpringReverb->StereoIR Cabsim->I2S Load max about 80% with everything turned on.

      \m/ :) More news: managed to port the Neural Network amp modeller from Seed by GuitarML (originally runs on STM32H7 i believe) to Tennsy, added a bunch of other stuff like: - new Noise Gate with external side chain input. This way i was able to...

      Thanks! Things got a bit more exciting - got the RTNeural library working on the Tennsy4.1. CPU load is around 45%, with the tone stack and stereo IR speaker sim tops at about 60%. Still plenty for reverb, delay and a few other effects.

      New incoming reverb for the library: ReverbSC ported from Soundpipe, original authors: Sean Costello, Istvan Varga This one is not to heavy on the CPU, but RAM hungry (387k). I'm still working on fine tuning the code. There will be 2 options...

      I have updated the example projects repo with a version for ArduinoIDE 2.0 and info on how to set it up. Tested on Linux only, the project compiles fine. https://github.com/hexeguitar/hexefx_audiolib_F32_examples
