Developer Matthew Fecher has introduced FM Player: Classic DX Synths, a free and open source iPad virtual instrument.

“It’s 100% free. No in-app purchases, ads, or anything to buy,” notes Fecher. “It’s multi-sampled from a DX7, a DX7II, and some bonus TX81z presets.”

In addition to the software being free, the developer is making the AudioKit ROM Player code available, so that you can create your own sample-based ROMpler type instruments for iOS.

  1. The DX7 is a pure synth. I’m 99% sure you can sample one. It is true that you can not sample a sample-based instrument, like the D50, or an SY99. And, you can not make a sample based instrument out of a synth that samples the DX7.

    That all may be a mute point, From their website, it does not look like they are “selling” anything. This is all free.

  2. It’s a better option than Yamaha’s “FM Essential” softsynth for iOS that only functions if your iPAD is plugged into an expensive Yamaha external keyboard.

    1. The FM Essential app is a one time unlock by plugging your phone into the Yamaha MX49. I did it for free at Guitar Center using their display synth, now I can use the app anytime at home. Also the Yamaha hardware synth was on sale for $349 this week on Amazon. Not that expensive, but compared to a free app on your iPad, then yes that is pricey 🙂

  3. If you want those (possibly rather awful yet nostalgic) presets again (DX7 piano anyone?) this is the app for you! 😀

    Though I must confess in addition to many beautiful sounding FM software synths for iOS I do rather like my TX-81z, probably for nostalgic reasons mainly through it is a vaguely fun pastime to try to program patches into its clunky front-panel interface, and it is a very capable 4-operator FM synth that does sound nice.

  4. CME Xkey 37, my favorite compact polyphonic aftertouch iPad keyboard! (Though I note the short ~2mm key travel isn’t for everyone, the poly pressure is something special…)
