DSP Program selector for FV-1 projects 16 programs

[Devoureddeth]

I know this exists else where but a centralized non-SMD version of this would be great all FV-1 products in one go. http://www.hexeguitar.com/diy/utility/fv1progsel

Note, the Octagon and other projects already have a rotary program select knob. A simple diode array is used rather than an 8 to 3 encoder IC.

I found out that the FV-1 has 8 built-in algorithms in addition to the 8 in the eprom... so for a 1 of 16 selector, you could use an up-down button to drive a 4 bit counter or similar (e.g., like https://www.ti.com/lit/ds/symlink/sn74f163a.pdf).

So many possibilities for sure.

Hexe's stuff is awesome. For years I've been dying for a Melusine but they're impossible to find and when you could still get them were +$350 used.

If you look at my Megatron build report you'll see I used a DPDT to access the onboard FV-1 patches as well as the eeprom. It's easy enough to do.

I assume you can program the FV-1 with 8 programs of your choosing.

Yes, you can order your custom set of programs right here:

Hexe's website is definitely worth the visit, he has an FV-1 controller computer board, as well as an awesome 4 W tube amp. Tons of stuff there.

The default FV-1 programs can be found in the datasheet:

I use a Ardunio Uno to program my EEPROM. Very generic but works

Do you have any guides you leveraged to go about this?

In this project there is a link to the documents on how to do this:

I'm working on an FV-1 module specifically to be embedded into projects like the program selector, presets, etc....

And of course, that will eventually be followed with a main board to support it.

Legend, thanks mate!
