Many of the vintage Roland synths – like Jupiter-8, MC-202 and Juno-106 – feature a delayed LFO which could sound like a vibrato that comes in after a while on longer notes.
It’s possible to do this effect with Doepfer A-147-2 VCDLFO, but the module can be a little confusing. So here’s how to do it (involving Make Noise FUNCTION but don’t worry, it’s expandable):
- Apply a gate to Signal Input of Make Noise FUNCTION.
- Send the EOR (End of Rise) output of FUNCTION to Delay Reset on Doepfer A-147-2.
- CV pitch goes in CV (1 V/octave) input of a VCO.
- Connect the signal from Out (not Delay Out) of A-147-2 to another CV input, preferably with an attenuator, on VCO. (If the VCO doesn’t have multiple CV inputs, then use a linear mixer.)
- Set the Delay knob on A-147-2 between 1 and 2; delay time is actually the wrong way around.
Now I just sold my A-147-2 module. It was nice an full of functionality but it overlapped, and every HP counts. Although, this cool delayed LFO effect, I’m no longer able to patch. I think.
