System-500 512
For starters, we have the 512 dual VCO; as the name tells us, consists of two voltage-controlled oscilators, each of which can be set to pulse, triangle, and sawtooth waveforms. Pulse width can be manipulated by panel control or even CV modulation. The oscillators’ frequencies can also be synced with each other in one of two modes (weak or strong) to acheive a classic ‘sync’ sound.

System-500 521
Second in the series is the 521 dual VCF module, featuring two separate low-pass filters, each with its own frequency cutoff and resonance controls. Each filter also includes a high-pass filter with a fixed frequency (although there are two switchable cutoff points)

System-500 530
The 530 dual VCA module handles the amplification in your signal chain; each amp mixes three audio sources, and each source has three CV controls available. Finally, the 530 has an enormously useful switch to select between linear and exponential response settings.
Amplification duties are taken care of with the 530 dual VCA module, with each amp mixing three audio signals and three CV controls for each signal. The 530 also features a selector switch for linear or exponential response modes.

System-500 540
The 540 is the next step in the signal chain, featuring a dual envelope generator and LFO, featuring two independent sets of ADSR controls. The sections can be triggered internally, externally, or even manually (separately for each envelope), and the output can even be inverted.

System-500 572
Last, but certainly not least, we arrive at the 572, which features a five-stage phase shifter, analog delay, a control voltage gate decay, and an LFO. The phase shifter includes frequency and resonance controls, and the delay section allows you to set the delay time and feedback. Both the delay and phase shifter allow for modulation via the internal LFO or even external CV signals. Finally, the unit features dry/wet controls, which can be controlled on the front panel, or, (you guessed it) CV control.

SYR-E84 Eurorack Case
Now that we’ve gone over all five module units, it’s important to remember that we’re going to need a nice rack to put them in. Well, I suppose you could have them sprawled out across the room, but what fun is that? The best option seems to be the SYR-E84 Eurorack case, a rugged and portable rack with a high-current power supply. Although it’s truly perfect for mobile producers or live electronic music performers, we’re fairly certain that SYR-E84 find its way into the hands of producers of all ability levels.
