New iOS Synth, Copperhead, Inspired By Vintage Synthesizers Of The ’80s.

Developer 4Pockets has introduced Copperhead, an AUv3 digital subtractive synthesizer plugin that’s inspired by the vintage synthesizers of the early ’80s.

But Copperhead offers features that were rare or unavailable in the early ’80s, like 16-voice polyphony, a built-in arpeggiator and a host of integrated effects.

Copperhead’s synth engine features custom waveforms, oscillator sync and various cross modulation modes.

At the heart of Copperhead are its two oscillators, which support basic waveforms (including sine, square, saw & triangle), as well as SuperSaw, Trapezium, and a user definable type. The Voltage Controller Filter section features LP, HP, BP and Notch filters, as well as some less common ones, like Formant, which can be used to create vocal-like sounds.

Copperhead also features twin LFO’s, with random and one shot functionality. It also supports Cross, Ring and FM modulators, in addition to low and high shelf filters.

Copperhead is ‘designed for iPad’, but also compatible with iPhone and MacOS.

  1. they should picture every piece of software with the inevitable mouse pointer; cause that’s what you’ll be seeing at the most.

    1. this community keeps having the worst comment section out there.
      great sounding synth for a magical touch screen for a price of a cocktail, cue bitching about imaginary mouse pointers.
      cant make this stuff up.

    2. Have you used an iPad? It has a multitouch display, which is fantastic for software instruments.

      Sure it isn’t as nice as real hardware knobs, but it’s way better than a single mouse pointer. Nice for mixing with multiple virtual sliders as well.

      DAWs and software synths are basically the killer app for multitouch displays. You can also plug an iPad into a Mac and use it as a multitouch display for your desktop DAW and/or plugins.

  2. £11.99 vs £1199
    Low environmental impact vs large environmental impact
    99.999%+ of the world’s population wouldn’t be able to tell the difference sonically.

    (This one’s for iOS, so the cursor is only there if you happen to have a keyboard and mouse attached)

    1. I really like developing patches and music on an iPad (or iPhone) and then being able to import everything into a desktop DAW like GarageBand or Logic.

      I also like it when iPad apps can run on Macs with Apple Silicon. I have a collection of amazing iOS music apps but I don’t know how many will run out of the box on macOS.
