Doepfer A-108

Lovely bread and butter module. Probably the most Moog-like filter Doepfer makes, though it doesn't sound exactly like the classic Moog ladder. By the time I finished my Euro modular I had only kept 3 filters, and this was one of them.

Straightforward multi-filter.
No frills
Sounds good but won't set the world alight.

Affordable

I have had the module now for about a week and a half and i am having a great time with it. I used it both as an oscillator and a VCF.

Setting up volt/oct the VCF in self oscillation and modulating it with a Make Noise Maths i was able to create a convincing birdsong, which i have posted on my youtube channel here, used it in the creation of a Karplus Strong patch where it controlled the white noise that fed a delay line used.

Few modular synth manufacturers make a 48 dB (8 pole) filter. It is capable of very steep cutoffs as you might expect, but there are also a number of less steep filter outputs. All in all a very useful and unusual module.
