I have an old, analogue tone generator which produces a tone at a certain frequency and a certain amplitude. When I am running tests I can see what's happening in one frequency but not in conjunction with others.
For the projects I am experimenting with I would want it to create more than one frequencies (maybe up to 12) at a separate amplitude each, so I'd be looking for 12 separate knobs for amplitude control and 12 separate knobs for frequency. Of course if it were digital you'd have "multifunction" buttons.
An additional feature would be the ability to vary the *amplitude* on each channel by a certain amount, % wise, like in AM transmission, based on a random generator or based on a modulating frequency.
An other additional feature would be to vary the *frequency* on each channel around the centre frequency by a certain %, like in FM transmission, based on a random generator or based on an amplitude waveform.
Eg I could say :
channel 1: base F=100Hz, A=1V pk, sine
channel 2: base F=1KHz, A=0.1V pk, sine, FM mod: 5%, random generator.
channel 3: base F=5KHz, A=1V pk, sine, AM mod: 10%, random generator.
Does such a tool already exist?
