This is an update of the Simple LFO module.
The major improvement is the implantation of an amplitude potentiometer on the PCB.
This is an outdated version, an update is available!
PCBs are available on Tindie!
Simple LFO 1.2
PCBs are available on Tindie!
I’m assuming that the amplitude pot should be logarithmic, but are you using a linear or log pot for the rate?
The amplitude may be logarithmic only if you privilege an audio use. With CV use in mind, linear is better: if you set the amplitude pot at 50% then you expect your CV output to be 50%.
A linear rate potentiometer will give you more control over high frequencies while a log pot will give more control on lower frequencies.
Thanks, that’s exactly the explanation I needed.
Sorry, if i missed this somewhere but does this require an AC or DC power supply? Thanks in advance!
It requires 3 DC rails: DC +12V, DC 0V and DC -12V.
But +9/0/-9 V might be fine too (2x9V batteries for example).
You can use something like my Mini Dual Power Supply.
