"his filter is not a clone of the ARP 4072 submodule. It does, however, have an identical topology with the same transistors and operational amplifier array. Some people may find this is close enough to use the "C" word but not here at STG Soundlabs, so in tribute to the origin of this filter design it is called the Post-Lawsuit Lowpass Filter.
And before you call to complain, let me point out that Post-Ambiguous-Legal-Action Lowpass Filter just didn't have the same ring."

"I recently got the Dave Smith Instruments MoPho real analog, monophonic synthesizer (serial #281), and while I'm already putting it to good use in my own music, I decided to make a demo of a well-known song to show how powerful, this very affordable analog synthesizer is.
I chose the Beverly Hills Cop theme music by Harold Faltermeyer, because it's based around synthesizers and really demonstrates the range of sounds from the MoPho - from fat, powerful basses to searing leads.
All of the sounds in this demo except for the sampled drums and a single DX-7 piano sound are from the MoPho, programmed by myself. Except for the drums and bass, all of the parts are hand-played without correction.
In my opinion, the MoPho is probably the best sounding synthesizer that's affordable for most people on the market right now. It's warm, thick but even deadly aggressive if you want it to. It even has 4 16-step sequencers ;)
"This is a vintage ring modulator design with bags of character. It is based on the classic ARP4014 sub-module which was used on the ARP2500 modular and ARP2600 semi-modular synthesisers. The design has a fully discrete core but uses two op-amps for input and output amplification.
A ring modulator has two main inputs, usually called X and Y, and one output. The output voltage is the product of the two input voltages. In other words it multiplies the two input signals together to produce a new and different sounding output. If you have two sine wave input signals then the output will have both the sum and difference frequencies. For example, if X is a 440Hz sinewave and Y a 40Hz, you would get a 480Hz and a 400Hz sinewave from the output. However, this is only really true in a perfect ring modulator... And this ring modulator is not that. Each input has its own differing non-linearities or imperfections. This greatly adds to the character of the resultant output.
The Oakley Ring Modulator features three rotary control pots. Each input has its own attenuator, and there's also a offset control for the Y input. In conjunction with the Y attenuator, this third pot effectively acts as a wet-dry control for the X input. But because of the non-linearities inherent in the design it also acts in more subtle ways.
You can also use the Oakley Ring Mod as a standard VCA. Just use the Y input as your CV input and X will be shaped accordingly.
Each input can be either direct coupled (DC) or high pass filtered (AC). The former allows DC and low frequency signals to be processed. While the latter provides a DC block to process only alternating frequencies. The standard panel design makes both types of input available with each having its own socket. However, you can use a one socket on each and then use a switch to select between the two modes if you prefer."
YouTube via analoq "Taking code from my diy softsynth I made this simple drum synthesizer which I am controlling with a Monome and Audio Kontrol 1. And just to spice things up, I throw a Metasonix TM-1 into the signal path. I like when software and valves play together :)"
"The classic Mellotron revised and reworked - seems a little bit DIY still though. And is it really worth having all those tape loops when you can use a sampler?"
