Barber pole flanging is actually something different. That's when you use a frequency shifter (not pitch shifter) and shift frequencies by a very small amount - it creates something a flanger or phaser, but it appears to constantly be moving downward or upward, rather than up and then down, cyclical...

In analog effects, we'd approach it with a noise generator into the input of a sample and hold circuit, a square wave LFO into the gate switch of the s+h, and we'd take the resultant random voltage steps and use that to control the thing we're modulating. Creating noise in the FV1 might be kind of c...

It looks to me like your feedback loop is around the pitch shift. You want the feedback coming from the output of whatever the last effect is, to the input of the first effect. So if you have pitch->reverb then the feedback should come from the reverb out and go to the pitch input. But, if you like ...

It's a little difficult for me to follow this code, but here are some things I see which don't seem right: You are writing to the DACR and DACL twice within the program, once in the limiter and again after the reverb. This is not what you want to do. I'm kind of surprised this works at all, actually...

Frank can respond with a deeper answer probably, but it has to do with the speed of the LFOs which do the pitch bending and crossfading. If the LFOs oscillate at a frequency related to the pitch you're playing, you can sometimes get a periodic cancellation which sounds like wobbling or chirping. But...

SKP out of range
Ran into a new error today, SKP out of range. I guess the SKP operation can only skip 64 instructions?
First, why is that?
Second, is there any better solution to this than to just SKP to a label in the middle of the program, then SKP again to where we actually want to go?

I want to create a code sitar emulator. Can you help me? I suggest a block diagram of the algorithm: Input => +1 octave => (+ 2 octave; reverb) => output. An +1 octave (POT2max = 2 input) should be mixed with clean sound. Reverb (POT0) should work with only +2 octave. +2 octave (POT1max = 2 input) ...

Thank you! This part I understand. What are these pieces of code? equ tovrx reg0 equ sigin reg1 equ lf1 reg2 equ lf2 reg3 equ lf3 reg4 equ lf4 reg5 equ lp_filt reg6 This is where you define the names for registers. When working with code, you have to write results to a register so that you can clea...

Are you familiar with designing analog distortion circuits? There are many different useful tone controls for a distortion. The simplest and most common is a single-pole lowpass filter. Here is one by Frank: rdax adcl,1.0 ; Read ADC left rdax lp_filt,-1.0 ; ADCL - lp_filt mulx pot0 ; * C (POT0 in th...

Are you using computer translations into English? Like Babelfish, Google translate, etc? It's sometimes difficult to understand your responses so it's harder for me to help. To get better at modifying programs, start with a simple goal. For example, you said that sometimes you have a program that is...

What I think is best is for you to read the knowledge base some more. There's more info there than we can cover in a thread. Here's some homework for you. This is how I began understanding how programs work. Once you understand these parts, you will begin to be able to read code and understand the s...
