SPC Plugins Intros ArcSyn Virtual Analog Software Synthesizer


SPC Plugins has introduced ArcSyn, a virtual analog synthesizer plugin, for Mac & Windows, that they say lets you venture into ‘unexplored sonic territory’.


  • No samples—all oscillator waveforms are generated from scratch.
  • Many unique waveforms including Sub-harmonics, Bit-Noise and FM Crossfade.
  • Unique LFOs feature wave sequencing and hundreds of unusual waveforms including many random types.
  • Powerful, self-oscillating filters based on the Oberheim Matrix 12.
  • Many unusual filter types like Frequency Shifter, Scramble and Multi-Alias.
  • Smooth, natural sound quality throughout—Oscillators and filters are 4X oversampled, all audio processing is done in 64-bit arithmetic and control signals are updated at 5500Hz or higher.
  • Comes with over 350 preset programs.
  • MIDI controller learn.
  • Easy program organization—rearrange programs and folders using your computer’s file system.

Here are the official audio demos:

ArcSyn is available now for US $99/79 EUR/£69 GBP.

  1. Wow! I really love the sounds in these demos. Nice to see some useful sound design elements like subharmonics. I’m curious as to how the implemented that.

  2. I messed around with the demo and was impressed with the variety of oscillators. The other cool thing about the oscillator set is the way they implemented the SHAPE knob to sweep through a wavetable for most of them.

    The big disappointment was the subharmonics and subharmonic sweep, neither of which did what the name implies. Not sure what it was, some kind of square wave or bit-crush thing, but not subharmonics. Too bad, as that is a fascinating and useful tone. If they could have pulled that off, it might have been worth buying.

    The filters & oscillators sound nice. The envelopes are fast, but for as fast as the refresh rate is (as mentioned above), I still wasn’t able to get a very snappy sounding envelope “pop”.
