[quote="frank"] I set POT0 to 50%, POT2 to 100% (all flanger, no chorus) [/quote] Frank maybe we talk of different programs here? I use rom_fla_rev.spn. The pots from 0 to 2 are labeled: reverb mix, flange rate flange mix according to my fv1 data sheet. And I set reverb mix to 0%, flange m...

[quote="frank"]So please try and let me know if there are any others that have a problem.[/quote]

Hello,

thanks a lot, chorus/reverb and tremolo/reverb are working now while flanger/reverb compiles but shows no reaction on the rate poti (pot1).

Sorry for not reacting earlier.

[quote="frank"]Hmmm, a quick test looks like you may be correct on this. Keith may have posted an old version of the programs by accident. I'll try to get hold of him and see if he has more info, it may take a few days as he is out of the country at this time.[/quote] Any news? Tanks, Herb...

[quote="frank"]I tried the pitch/echo program (rom_pt_echo.spn) and it worked properly, POT0 controlled pitch in left, POTs 1 and0 controlling echo parameters in right. Any additional info? Can you monitor the values on the POT pins?[/quote] Hi, sorry, my bad, you tried the example which I...

Hi, when I rebuild the FV1 ROM programs from the provided sources, some of the pots have no effect when running from the external EEPROM of the dev board while they work from internal ROM. Examples: On Programs 0 und 1 (Chorus / Reverb and Flanger / Reverb) Pot 1 (rate) has no effect if run from ext...

[quote="frank"] If this does not appear to be happening in your case please check that you have the capacitor on the xtal pin as indicated in current versions of the datasheet. We have discovered some crystal makers cut the crystal in a manner that can cause it to come up in a high order h...

Hello, [quote="frank"] When the FV-1 starts up the internal clearing algorithm clears the entire memory before loading the program and unmuting the chip. [/quote] I guess it does but I guess the input pulse which makes the clip led flash on power up (in our design as well as in the dev boa...

Hello, when the fv1 starts up and a long reverb is selected the internal mute is not long enough to suppress the complete reverb tail. So the units start up with a noise on the headphone output. This can be easily tested with the dev board but some FV1 samples are much noisier than others. Our dev-b...
