Roland, the leading japanese corporation of musical instruments, announced 4 new modules for the System-500 Analog Modular Synthesizer line.  This is a line of Eurorack format modules based on the previously released and widely known Roland System-700 and System-100m, which includes all the main modules (oscillators, filters, effects, etc.) needed to create a modular system. They were quite warmly received by customers and are in demand.

So, the new modules were: 510 Synth, 555 Lag/ S&H, 531 Mix and 555 VCF.

510 Synth (20HP) is based on the 110 VCO/ VCF/ VCA module from the System-100m line and combines the best of the System-500, being a one-piece, single synthesizer module. It has an oscillator providing three basic waveforms (square, triangle, saw), a classic Roland multimode VCF (LPF/ HPF), and a voltage controlled amplifier. The module has several inputs for external audio signals and modulation, as well as outputs with Eurorack and a linear signal level for convenient interaction with other modules of this format, as well as with other devices. 510 Synth is designed to work without cables and, according to the representative of the company, suitable for beginners and for those who want to make a characteristic for Roland sound in their setup.

555 Lag / S & H is a five-in-one module that brings many useful features to the modular system. The designers tried to combine traditional and non-traditional modulation resources, including ring modulation, sampling-storage with seven waveforms and an integrated low-pass filter, a low-frequency generator with an amplifier and envelope and portamento in a double copy.

531 Mix is ​​a mixer module created under the inspiration of 131 output module. It has 6 channels, each of which is provided with an input, a volume control, a pan handle and a channel shut-off button. The values ​​of all pan controls can be controlled by CV signals, which allows you to create interesting stereo effects. In the headphone output section there is a volume knob, as well as a multi-format input, allowing to use both 3.5mm and 6.3mm jack.

505 VCF - filter module, repeating the sound of Roland SH-5, the filter of which is considered one of the most outstanding among all monophonic synthesizers. It has switchable outputs, built-in amplifiers and the ability to control the cut-off point and resonance with CV. Thus, this module, having a rather compact 16hp format, gives two different vintage filter sounds.

All these modules, of course, have a rich functionality and excellent branding sound of Roland, but it is not yet clear whether they will be in great demand due to the latest news from the company Behringer, who are also going to release clones of modules from the System 100-m line, but for much more affordable prices.
