eurorack DIY FV-1 platform?

[japes]

Hello all - curious if this is something that exists. I have a DIY FV-1 guitar pedal I quite like, but it would be nice to have one in eurorack format. Is this a thing?

the D103 on this page for example

Not sure if you can still get 'em, but there's the 12HP and 8HP Dervisheses.

There is this option

There's also submodules by Electro Smith which is basically an FV-1 on a little breakout board. Relatively easy to implement as Eurorack module. I built mine according to a schematic I found here on the site.

O.K.
Mikhail at https://recklessexperimentationaudio.com/ has created prototype PCBs and Panels in Eurorack format (not yet available for sale). They provide the Electro-Smith.com submodule with all that's needed for a complete module. Here;s a demo using a couple of them with custom Delay and Reverb programs.

Once you have coded on a platform like daisy is it simple enough to port this to your own circuit?

@magicdust I'm using the "SpinCadDesigner" which is a GUI. It's very different (easier) from C++ development for the Daisy.

Spin Semiconductor has an IDE for programming for the FV-1 (SpinAsm). But it is all coding.

This is a better environment – SpinCad-Designer. It’s a gui with a simulator! Very effective, but perhaps not as well documented as I’d like.

If you want to program the FV-1, I highly recommend getting the dev env board ( FV-1 Development System :: SPN1001-DEV ).
I thought it would be cheap and “fast enough” to program the EEPROM via a TI MSP430 launchpad micro controller dev board … my mistake!

wow this spin cad designer looks amazing, i was always put off the idea of lookin into fv-1 coding but this makes it seem feasible. then again, there are sooooo many good algorithms out there already, pedal pcb, happy nerding stuff etc etc.

that being said, i second the notion for the electro smith submodules, i use a ocuple and they are extremely convenient. strange that there is no cheap diy eurorack adapter pcb out there yet, recklessexperimental looks promising.

there are some small pedalpcb fv1 boards that would also fit into eurorack sizes but you'd need a bunch of level shifting because those expect guitar/line voltages.

fwiw happy nerdings FX AID (XL) absolutely nailed the best fv1 implementation with the firmware-webapp, update-via-audio, 32 algo-slots and full cv access to all 3 fv1 parameters. so unless you really are really commited to diy this is the best option.

Spin cad is decent training wheels, and a useful reference. However, for any real work on reverbs you will need to learn to program in the assembler.

I also think the official dev board is a worthwhile investment. It’s very reliable, and well integrated with the IDE.

i've been meaning to build an FV-1 euro platform for ages, but never got around to it.

not sure how much the dev board costs or its availability these days but it would be good to implement the same functionality into the module (pins for programming basically).

would love to learn assembly programming but the learning curve is more of a learning wall.. spinCAD is amazing but definitely feels limiting.
