PortaFM是第一个成员的chipsynth合成器生产线，比特精确复制一个老式低成本2运营商FM芯片(OPLL)内的一个新的合成器设计。PortaFM是一个独特的两个操作FM synth与一个非常古怪的功能集。
80年代后期的“PSS”系列是俗气的，由塑料制成，但有一个非常独特的声音，失去了时间。本系列中最著名的合成器示例包括PSS-140、PSS-270迷你键盘和SHS-10 keytar。Plogue不愿意仅仅复制过去的版本，他设计了一个新的合成器，其特点是与这些合成器产生的声音相同，但这次有了更多的处理能力来控制和调节它的特性，所有这些都以一种方便的虚拟仪器的形式出现。
PortaFM使用一对循环精确模拟的OPLL (YM2413) FM芯片核心作为其主要synth引擎，另一个核心专门用于鼓的声音，所有这些都可以创造性地分层。
独特的“lofi”质量的OPLL从来没有再创造这样准确的之前。Plogue超过15年研究老式数字声音发生器的经验被推到了极限。全新的数学模型是使用我们的定制硬件辅助系统测试程序由Plogue的室内逆向工程团队在蒙特利尔建立的。
chipsynth PortaFM is the first member of the chipsynth synthesizer line, a bit-accurate reproduction of a vintage low-cost 2 operator FM chip (OPLL) inside a new synthesizer design. PortaFM is a unique two operator FM synth with a very quirky feature set.
The late 80’s ‘PSS’ series was cheesy and made of plastic but had a very unique sound which was lost to time. Some of the most well known examples of synthesizers in this series include the PSS-140, PSS-270 mini keyboards and the SHS-10 keytar. Not willing to just copy the past, Plogue designed a new synthesizer that features the same sound generation found in these synthesizers, but this time with much more processing power to control and modulate its features, all in a convenient virtual instrument form.
PortaFM uses a pair of cycle-accurately emulated OPLL (YM2413) FM chip cores for its main synth engine, and another core dedicated to the the drum sounds, all of which can be layered creatively.
The unique ‘lofi’ quality of the OPLL was never recreated this accurately before. Plogue’s experience of more than 15 years studying vintage digital sound generators was pushed to its limit. Brand new mathematical models were built using our custom Hardware-assisted systematic testing procedures by Plogue’s in house reverse engineering team in Montreal.
