Do you feel that what I am trying to accomplish makes sense by using Arduino Nano? Is it fast enough.
What frequency resolution do you need?
Resolution it can be 1-0 signal, it doesn't matter.
As you slowly reveal more information you get better answers.It is quite frustrating when people do this. A signal generator is a totally different thing to an audio oscillator.So you want to make a four channel audio oscillator. How do you want to control the frequencies?What waveform do you want from it?What frequency resolution do you need?What frequency range do you want?
The only issue I seem to have is how to get the signal out from multiple ports simultainously
how to control each output same time with different pots
QuoteThe only issue I seem to have is how to get the signal out from multiple ports simultainously The simplest way is to connect the outputs together through a resistor on each line. This acts as an audio mixer.Quotehow to control each output same time with different potsEach output will be controlled separately. That top link I posted you looks like your best bet.
The code is written in unfamiliar way
