That's what I figured was happening but didn't know if there was a slick work around...
Thanks guys! I'll revisit this approach via hardware...

Stereo/Mono Inputs & Auto Sum to Mono Output
Greetings All! I'm working on a stereo program that carries the dry signal through, left input to left output & right input to right output. Obviously this isn't a problem mapping the inputs to the outputs, but I'm having an issue when the user unplugs the right input, I'd like for the left inpu...

Re: Using ADC value with SKP instruction
Hey Bennett!
This seems to be working but every time the signal starts boarding the threshold (i.e. just a little be below and back above again) I get a slight crackling sound in one of my output channels.
Any thoughts on how to get rid of this?

Re: Using ADC value with SKP instruction
There is always noise in an ADC signal, no way around it. Try the following: 1. Read in ADC and take absolute value so always positive 2. Low pass filter it, basically we want the envelope. 3. Select a threshold value (i.e. 0.1) so that above this value is considered signal and below is considered ...

Re: Popping on Startup
Yep, tried it again and it pops every time its turned on and off vs. only after the first initial startup.
Is this common problem folks are having or should I look at a re-design of the buffered bypass portion of the circuit?

Re: Popping on Startup
Thanks ice-nine! I feel like I've tried this by hand soldering a through hole resistor to my PCB and it made it pop every time I turned it on and off vs. just popping at startup. I'll give it one more shot and post back with results. How are you guys incorporating "trails" into your circui...

Popping on Startup
I'm hoping this is a simple fix, please excuse my ignorance as I'm not an electrical engineer. I'm trying to create a buffered bypass by switching off the input to the FV-1. This seems to work: https://drive.google.com/file/d/1rAAKGm1QVKdre-AGHgYEZ0UlxEIAn0gl/view?usp=sharing but it gives off a pop ...

Re: Fade In Help
Thanks Frank! I'll try this out when I get home tonight and adapt it to fit my use. This exercise has really helped me to better understand what is going on behind the scenes with the FV-1, although I still have a lot to learn... :D I'm still a bit confused on how the code below keeps "gain&quo...

Re: Fade In Help
Thanks Aaron! I did some research yesterday and noticed that my skp routines were off. I believe I've fixed that part of it... I basically added a "skp gez,end" line at the end of each block (and put the "end:" statement at the very end of the program) to skip the rest of code so...

Ok, here is what I've come up with... it's clearly not the way to do it as this code doesn't work. Not sure what I've done wrong, when I load the program I get no signal coming out.

Re: Fade In Help
Tanks for your help Frank! I’m not completely sure how to convert this to FV-1 code but the general concept makes sense. I’d rather try and figure out how to convert it on my own, then just ask for the answers. I noticed FV-1 code doesn’t have an IF/THEN/ELSE statement, can you point me in the right...

Re: Fade In Help
Frank,
I’m trying to create a Bloom type reverb where the trails gradually fade it. Probably the best example would be here: https://m.youtube.com/watch?v=KclJxqde8NQ

Fade In Help
Greetings All! I'm pretty new to FV-1 programming and looking for a way to fade in a signal. I'm assuming it'd be something similar to creating a compressor with a slow release time. I've been through the free DSP programs and have a decent understanding of the compressor/limiter examples but not su...
