More effective Phase shifting ideas

Does anyone knows ;how could be the phaser program more effective (I just tried on demo program by changing the values of the width control pot values it increased a bit more ,and feeding back the phase shifted signal to the input again but didn't effect the signal , I think I need more ) ,maybe lik...

Hi ,donstavely ,I m interested in your code .I have a question; ; Need to convert period to frequency ; rdax avper, 1 ; get smoothed period log -1, -0.49 ; need 1/X, the offset scales frequency exp 1, 0 ; linear frequency wrax freq, 0 ; save it if I didn't miss understand this is for 1 octav down or...

I put a simple pic programmer for serial port and some relays with one fv1 effect board in to a box .When I switch on ,the 2432 disconnect from the programmer and when I switch off the board,the 2432 connect to the programmer by the relays,and thats enough for trying many programmes. :lol: But insid...

differo ,how is the pitch shift effect in the holy stain I just wonder if there is a time delay between the dry and pitch shifted signal.

Alesis uses AL3201 ,Behringer uses V1000 .Not the same chip but can be used as the same or they are crossreference of each other.But needs DAC -ADC and LP filters. :D

Is there anyone who sells the FV-1 for 2$ ,I want nothing more.Because I haven't forget the days yet,that I used to pay 4$ for 4 pieces of PT2399 to get very simple reverb sound with using them in 4 comb filters. :)

One thing a scope will help with is to look at how fast the power rails come up. If too slow that can cause problems to the internal reset. Yes ,I dont have scope that s the main problem for me ,so I have to economize with the digital multimeter. :D I had the problem , slow rails come with another ...

Forget the scope.what do you expect to see on scope? :D Make simple in out program like rdax wrax ADC to DAC and try the chip with external and internal programs .We can not solve the problem by ourselves with only datasheet ,need more information ,it s like a closed box. But I solved my problem by ...

It just sounds 'PLOP' or PLOP sounds :D than finish.Than alittle bit deep sound like dc as saturated too much. But I have no heat on chip.Inspite of shorting the inputs to the ground (not the pins of the chip directly ,theboard inputs are grounded)output voltage is sometimes 2v for the one channel,t...

Publishing a service datasheet is a good idea includes everything or so close to everything about the chip... :D
