Doepfer A-137-2 Wave Multiplier II Demo
A quick demo of Doepfer's A-137-2 Wave Multiplier II.
The module uses comparators to generate four phase-shifted copies of the incoming signal to provide a robust, multi-oscillator type sound. Think 'super-saw' without any of the phase cancellation issues usually associated with mixing multiple VCOs.
In the first example you'll first hear the source saw, then the A-137-2 and lastly three VCOs.
The next clip shows that the input level clearly plays a role in the resulting sound. At the beginning you can hear the comparators struggling to lock-on. I found the sound to be most pleasing around the '7' mark.
You can get some very nice effects if you have tempo-sync'd LFOs. In this example I used two S&H outputs of my Kenton Pro 2000 II.
This shows what happens when you feed the A-137-2 with a sine and then a triangle (it won't work with pulses). A nice buzzy sound, but not quite the same as mixing multiple sines or triangles.
And finally, a short demo of what two 'five-VCO' parts can sound like in the mix. Apologies to 808 State ...
