Inphonik RYM2612 – VST synthesizer based on Yamaha chip from SEGA Mega Drive console
In 2016, the RYM2612 synthesizer from Inphonik was released for Propellerhead Reason. The instrument came in the form of a Rack Extension and was a virtual copy of the Yamaha YM2612 FM chip, which was responsible for outputting sound to the SEGA Mega Drive console. Recently, the plug-in developers announced the release of the synthesizer in VST, AU and AAX formats.
The creators claim that the plugin is a very accurate and accurate copy of the original chip. The developers have recreated all the circuits for the passage and generation of the sound signal, which made it possible to achieve an authentic sound. To the delight of fans of 8-bit consoles and chiptune.
Not without a few improvements.
So the developers added a separate PCM channel with a virtual eight-bit audio input. The RYM2612 FM also features a dedicated effects section and Sample Playback support. In addition, the number of votes was increased from six (like the original) to 16. Also, the tool got the ability to apply filtering on the output, which can be turned off at any time.
The RYM2612 FM is equipped with four separately controlled oscillators. Users can choose from eight algorithms that determine how the sound is generated and passed through the various sections of the synthesizer. During operation, the oscillators generate a sound wave and then mix the generated signal with another sound wave that has passed through the envelope section. The generated waves can be further processed in the phase generator, feedback and detuning sections. Finally, the virtual chip is equipped with a simple low frequency oscillator that is used to vary the signal’s height and amplitude.
In FM synthesis mode, the frequencies of each oscillator are somehow related to each other. The Yamaha chip was also equipped with a Special Mode, in which the oscillators operate at their own frequencies that are not associated with other components of the system. In CSM mode, the oscillators quickly repeat each generated sound, which creates a richer sound than the usual delay effect.
