Spin Semiconductor

I have a program that has both a variable delay and a reverb algorithm. I want to add a variable predelay to the reverb side, but I'm not sure how to do that if I'm already using the addr_ptr for the 1st delay.

thoughts?

I want to try input an external LFO to the FV-1. Could this be done using one of the POT inputs?

There is no way to do an indirect write like you are trying to do, only an indirect read using RMPA. But as Digital Larry said doing it this way will not do what you intend. You will either have old data in the buffer or if you add a clearing routine you will have impulses of new data as the POT is...

I'm still having some trouble with this. Is it possible to write to a memory address using a register as the address marker? I want to do something like this, equ length 10000 mem del length equ dly reg0 ... rdax adcl,1 ;read in input wra del+dly,0 ;write to delay, where "dly" is derived f...

the last 2 lines are reading a signal and writing it to the right output for the purpose of driving an LED in sync. If you remove the ldax Led line, the right output will go unused and no more clicking.

Maybe Frank will chime in with some info.

ok thanks. nice new website btw.

I was thinking in a delay, if you change the input address and leave the output address constant, you should be able to change the delay time without shifting the pitch of signal already in the buffer.

can the wra or wrap instructions be used to write to an arbitrary memory address while reading from the end?

Fired up my dev board tonight, and "wrote" my first program. I took the Trem/Reverb from the ROM and stripped the reverb, made it stereo and drove channel 2 using an inverted LFO to make a stereo I/O panner. ;Stereo Panner ;pot0 = ;pot1 = trem rate ;pot2 = trem depth ; equ sigin reg1 equ t...

I looked that up right before asking my question too! Thanks all.

thanks, I will look into that.

I see, thanks. Could an allpass applied to an LFO to give arbitrary control over the phase?

Hi, I'm new to the FV-1 game. Is it possible to generate a 2nd or slave LFO that has a controllable phase offset from a master LFO?

Thanks.
