Frequency dividers are useful for emulating hardware electronic organs, or string synthesizers that utilized the same approach for generating their sounds. There are two approaches that can be used here:
The first one uses a stock module, the Binary Counter 2, and the second method uses a third party module from Elena Designs, the ED DSP Timer. Both these methods work well in the audio frequency range as well as the lower frequency ranges used for sequencer clocks etc.
Note: When used as an audio frequency divider for String Synthesizers etc, the only audio waveform available is a square wave, because we are dealing with binary (on/off) operations no matter what waveform you feed into the DSP Timer or Binary Counter the output will always be a square wave.
Using the Binary Counter 2 as a Frequency Divider.
All that’s needed is to feed the input frequency (F) into the Clock plug, and take the relevant outputs from the Counter
Note: B0 = F/2, B1 = F/3 and so on.
Using the ED DSP Timer as a frequency divider.
It’s quite simple to set this up as a frequency divider. All that’s needed is to set the Mode to “Bistable” in the properties, and it will divide the input frequency by two. There’s no need to worry about the T1 and T2 plugs as they are unused in this mode, just feed the Audio (or clock) signal into the Trigger plug, and the Output will be a square wave at half the input frequency.
By chaining the timers we can get F/2, F/4, F/8, F/16 and so on.
