Another way to look at this is why run at such a high sample rate if not necessary? Guitars have a limited bandwidth, even after many effects are applied so why run higher than actually required? Lots of pedals run at 16KHz sample rate so they have 2 seconds of delay available. An electric...

You can do what ever changes you need to so you can handle hotter signals but keep in mind: 1. The pedal was designed for guitar level signals with plenty of head room in the op-amps to avoid clipping/signal inversion error in the TL072. 2. The filtering around the op-amps is for pre/post...

As Digital Larry mentioned, the FXCore is already available but it is not source code compatible with FV-1. FXCore uses a different processing structure, etc. so making it source compatible would have limited the chip. But it has all the functions to replicate the instructions of an FV-1 it just...

Forgot to mention that the official tool set (assembler/preproc/GooeyCore) will support the Sandbox pedal so you can use any tool (web or computer based) with both the dev board and the Sandbox pedal. This updated tool set will be released when the PCBs are released.

As I said, once they are proven. First pass is just arriving this week so need to build and test, watch the github link as they will be posted there when ready. Web based assembler is done and posted and should work with the existing dev board via WebHID (use Chrome or Edge browser), the...

There is, Matthew Farrow of Disaster Area Designs/Alexander Pedals and I have been working towards an open source PCB/pedal design/assembler, the Sandbox FXCore. Assembler is done and online https://fxcore.sandboxpedal.com/ , Matthew released the first pass of the PCBs and he should have them...

Sandbox FV-1, USB-C interface to reprogram EEPROM, switches for stereo or mono modes, allows 6 programs plus through program (program 0) for bypass, browser based assembler so works with Windows, Mac, Linux, etc., open source design and firmware https://sandboxpedal.com/ Initial design by...

Yes, we are always looking at feedback and suggestions from users. As an example we are working on 2025.2 and one of the main updates will be including the FXCoreMP macro processor tool from @Cabintech in the all-in-one package. Looking at also including it in the Win X64, Mac X64 and Mac...

Updated tool set released for FXCore, lots of updates to the assembler. See https://www.experimentalnoize.com/product_FXCore.php

V2.1 now available, added undo stack, can select and delete multiple blocks, text blocks, background grid to align blocks, few other items and new blocks added to util library.

V2.0 released, added color to blocks, group select and move and a few other details.

It really breaks down to the following: 1. No programmer other that the Spin dev board is compatible with the SpinASM s/w directly. 2. Any programmer that can read Intel HEX format files and is able to program 24LC32A EEPROM will work 3. From SpinASM you need to make a project (see PDF on...

Included in the ZIP file of tools for the FXCore on our site: http://experimentalnoize.com/product_FXCore.php Available for Windows x64 and x86 as well as Mac AppleSilicon and Intel based Basic intro and example building a pitch shifter at

We have released an update to GooeyCore, the GUI for FXCore development. V1.5 can now call the preprocessor and assembler directly so it is easier/quicker to test new patches. Some minor updates to libraries also.

Actually this is the reason for the ICP board, just need access to the I2C lines on the PCB to load new programs. FXCore assembler can talk to ICP then plugged into your pedal and it thinks it is a dev board. There are people working on PCBs with the I2C lines on a header just for this reason...

After you do it a couple hundred times it isn't too bad;)
