Synthesizer

iOS and iPadOS

Synthesizer 12.0 is out, now accessible with VO and DirectTouch.

You can play it with a fretless sound pad within the app or connect a MIDI keyboard to your phone, iPad or compatible MacBook.

Turns your iPhone or iPad into a groovy synth based on additive, subtractive and fm sound synthesis.

One of the first synthesizers ever built for the App Store, originally released with the very first iPhone back in 2008.

Features:

5 main oscillators
frequency modulation
lfo
chorus
pitch shift
modulation wave forms (sin, triangle, sawtooth, rectangle)
attack, decay, sustain and release
noise
distortion
cutoff
delay
bitcrusher
presets
wave shape view

External MIDI Support:

The app automatically listens to any connected MIDI input. The app responds to notes, modulation wheel, and pitch bend in real time, while still letting you use the on-screen pad at the same time.

TIPS:

Setting Synthesizer up as a real instrument in GarageBand on your Mac will enable you to use all recording, looping, mixing, and effect features with Synthesizer. You can also create music for itunes or ring tones. Read GarageBand help for details.

If somebody wants to try it, I can provide some Apple promotional codes for download.

I'm always happy to see more music production apps and plugins becoming accessible. I was involved with testing a few so I'd love to try this one out.

Quick question. Is the current version in the app store accessible, or is this about testing a version for accessibility? Because if the one in the app store is accessible, I'll just go buy it.

According to my tests it is fully accessible with VO and Direct Touch. If you encounter any problems please post them here.
