That is the method I have always used, with both inputs directly linked together. I was just wondering if this was good practice or may introduce a small hum. Would separating the inputs through separate dc blocking and LP filter networks benefit at all? ;read both inputs and store in 'dry' registe...

If you don't bypass the inputs there's Vcc/2 on each one. I'm tying both together and reading them both also. That is the method I have always used, with both inputs directly linked together. I was just wondering if this was good practice or may introduce a small hum. Would separating the inputs th...

I thought doing this but with digipots controller by another uC and a control input (maybe the unused ADC). So when that control input is high the pot value will affect a set of registers, and when it's low other set of registers. It's a nice workaround, at least for prototyping where you have tons ...

I'm using the cho rdal to read the value of the LFOs. I need to use sin0, cos0, sin1, cos1 for several stages of the code for synchronize effects. Started with some simple tests reading the LFOs values and sending to the DAC's. The sin0 and sin1 are perfect, but when I try to see the cos0 or cos1 in...

I'm doing this in a design for feedback (not enough pots to do it digitaly) using the same LPF as in the input. Yeah I have also done the same before, by using the left output to feed the right input for a feedback control, I did use an op amp buffer but also kept the same output input filtering. I...

Thanks Sean, the pre/de-emphasis is how it has been done now and the results are a big improvement. @Sweetalk in the version I have that just has unity gain buffers which I was asking about originally, on the output of the FV-1 using a 1k - 100n R/C combination works well but experiment from 33n to...

Power is 3.0 V clean, regulated, locally bypassed on the daughter board. It's supplied by a L78L33ACZ with a 47uf output filter (minimum required). The same basic artwork is used in a reverb pedal that sometimes (although rarely) does this same thing and uses a 9V external plug in supply and the sa...
