To do a ring modulator, you need to multiply an input signal by an LFO. The internal LFOs of the FV-1 are limited in frequency range, but this should work: Start by initializing a SIN LFO: skp run,endset wlds sin0,0,32767 ;output = +/-1, freq = 0 endset Then adjust the frequency with a pot: rdax pot...

By nesting allpass filters, do you mean inserting an AP in the delay of another? As I recall, there ws no benefit and the code is a bit bigger. I have built all-AP reverbs though. The first Midiverb had a few as I recall. Very limited RT range, but also very interesting. I find the delays of a typic...

Sean: Been thinking this over... Maybe you need my short lecture on reverb programming. I hope its short enough... First of all, if anyone tells you that his algorithm is truly representitive of a real space, he's kidding himself, you, or both. Real spaces are hideously complex compared to a simple ...

reverb descriptions
I love your questions, curious are you! To the best of my knowledge, with the exception of some possible inside jokes that I have not been privy to, reverbs are named according to their sound. -Since the digital methods that approximate the acoustics of physical structures are recent compared to the...

Sean: Sorry, I just replied to your first message; I'm new to this forum stuff. As a suggestion, think of two taps on a delay, summed to an output; this will cause certain frequencies to reinforce where the delay between the taps causes the two outputs to be in phase, canceling when the phase relati...

Sean: Sorry I can't help more. I wrote the article on the website you cited, and it's the result of my experimentation; be advised, filters (HP and LP) within the loop greatly enhance the 'naturalness', if that's what you're looking for. It's the all-pass that does it. Everything comes from the flat...

reverb algorythm development & history
Sean: Don't know much about the history, but have spent years developing commercial reverbs. The first reference to all passes I recall was an AES issue that detailed Schroeder's work, a terrible sounding algorythm as described. The tinny sound of the MXR reverb (my work) suffered from this problem....
