OK, just took a closer look at the code, and it looks like the tapped early reflections delay line has the output tap code commented out. So, all of the ld1, rd1, etc. values don't actually do anything in this code. The early reflection delay line has several points that are read, diffused with an a...

Re: Using a microcontroller to clock the FV-1?
If you feel like checking it out I have a ZDSP card (or several) in progress. https://www.instagram.com/p/BNf9BNIAS4j/ Not sure why it took me 6 months to see this, but it sounds INCREDIBLE! That is some amazing time stretching/scrubbing going on there. Very Gantz Graf. also assumably have a Z-DSP,...

Using a microcontroller to clock the FV-1?
Hi all,
Has anyone used a microcontroller to send a clock signal to the FV-1? Is this doable with something like an ATMega328?
Thanks,
Sean Costello

Just saw that the ATMega328 is available in SMD: http://www.mouser.com/ProductDetail/Atmel/ATMEGA328P-AU/?qs=K8BHR703ZXiCmmgp6%2FGNmQ%3D%3D Question: If the FV-1 ROMs were part of a program that was flashed to the ATMega328, and I2C was used to write the programs directly to the FV-1 (i.e. no interm...

Do you guys experiment a high pitch whining with the ramping using this code?, I can't get rid of that!. The whining noise is due to the lack of interpolation when changing the delay length. The delay length change is being smoothed out, but it is still quantized to integer sample delays. Sean Cost...

Re: HIgher-order filters?
I was looking at some analog SVF designs today and saw a couple where there are a few more integrators inside the loop, for example to make it a 4th order filter. Up to now if I wanted a 4th order filter (which is not very often, for guitar) I just cascade 2 2nd order blocks. But if you want LP and...

Thanks for the info Frank, I dodn't have a quality scope at my disposal anymore to use but have managed to get the result in the end. The power lines are clean and no noise on the inputs to the FV-1, so I tried a program with just a freq generator to output to the DAC's which still produced the whi...

Delay RAM floating point format?
I read in the manual that the FV-1 delay RAM is 32k by 14 bits. What is the floating point breakdown for the delay RAM? In other words, how is the 14-bit word divided between mantissa, exponent, and sign?
Thanks,
Sean Costello

FCC Compliance tips?
I just came across this article: http://www.effectsbay.com/2014/05/fcc-regulations-for-pedals/ $450K is a pretty significant penalty. Any tips for designing circuits with the FV-1 that would be compliant with the FCC regulations? Obviously, the circuit itself would have to be tested - just wondering...
