FV-1 vocal reveb pedal design problem..............

[nguitar12]

I want to bulid a vocal reveb pedal using spin FV-1 chip. I don't need other effect.
The pedal should have 5 knob which control pre-delay, decay, damp, mix and a pot for the selection of different kind of reverb.
I have seen a schematic and layout  on spin's site which included almost everything I want:

http://www.spinsemi.com/mixer_application.html  (see 3K :: 8 Program - 3 variable module)

However I am not so sure about how to use the PROGRAMS file which is included on the web site. Also it seem that there is no "mix" control on this module. I am not a expect on electronic just wonder if anyone here could provide some information on this  that will be greatly appreciated.

The "programs" ZIP file would need to be extracted and then you use the Spin assembler/IDE (Windows only) to create a HEX file which you'll have to load into the EEPROM.  More info about this can be found here:  http://www.diystompboxes.com/smfforum/index.php?topic=109557.0

You'd need to make a mix control externally to the FV-1 board probably.  I'm guessing that the supplied programs are "wet" only.

Is working with FV1 chip a difficult task? Will I need a special programmer in order to program this chip?

Working with the FV-1 is certainly more difficult than building a single transistor boost pedal.  I would not recommend it as a first project.  Do you need a "special" programmer?  Anything that can program the 24LC-whatever EEPROM you use should work.  Most people use a PICKit 2 type programmer.  I'm still using the Spin development board which connects directly to your Windows PC via USB.  It's more than $100 to buy it, but if you value your time, it does get you working with the chip quickly.

Thanks. I think I better stay away from the FV-1 then
