The A 101-2 is a vactrol based lowpass gate. Any questions? Lowpass gates (LPGs) are devies that can act as lowpass filters as well as amplifiers. And a combination of both.

Doepfer A-189-1 Voltage Controlled Bit Modifier / Bit Cruncher
This is an interesting module if you are into distortion, low-fi and all kind of weird effects.
Doepfer A-117 Digital Noise / 808 Source example
The A-117 is a versatile digital niose generator. It has two parts: an „808 Sound Source“ whith a 6-oscillator output (cymbals) and a 2-oscillator output (cowbell) for percussive sounds known from an 808-style rhythm machine as well as a digital noise output.
Doepfer A-188-2 Tapped BBD example
The A-188-2 is a Bucket Brigade Device with several taps and extremly versatile sound possibilities. It can be used not only for flanging and delay effects, but also for Karplus Strong synthesis as an oscillator.
Doepfer A-188-1X BBD example
The A-188-1 is a Bucket Brigade Device that can be used not only for flanging and short delay effects, but also for Karplus Strong synthesis as an oscillator. Here’s a short sound demo:

Patch used: An A-155 Sequencer triggers an A-142 VC Decay envelope which controls an A-132-3 VCA (short decay time). VCA input is some noise from an A-117. VCA out goes into an A-188-1X BBD. The BBD frequency is controlled by the A-155 and an A-185-2 (to switch octaves – something like octaves: 1 oct down every 30 seconds).
In the feedback loop, an A-108 is inserted with bandpass out, no emphasis and manually changed filter frequency. BBD output is sent into another A-108 (filter frequency is controlled by BBD frequency VC out), the 48dB out is then sent into DAW.
