SunVox

From the App Store: “SunVox is one of the most powerful music creation tools for iOS. It is a small and fast cross-platform modular synthesizer with pattern based sequencer (tracker).”

It can be run as both an AUv3 and IAA app. As an IAA app, it can be used as an audio effect.

SunVox can be used with or without its built-in tracker (sequencer) as a modular synthesizer and custom effects unit.

App type: App and AUv3

^{From Littlewoodg:}
SunVox allows you to create your own custom effects processors – custom delay, echo, reverb and distortion effects – and a lot more.

Currently, to use SunVox to process external audio, it must be used in standalone (IAA) mode. To use SunVox as an audio effect processor in AUM:

1. Open SunVox in standalone mode.
2. Add the Input module in SunVox.
3. Go to AUM.
4. Add SunVox Filter (IAA) to FX slot on an AUM channel strip.

This same process should work in other hosts as well.

^{From Carnbot:}
To get AU sync options, go to project properties where there's the option to receive sync from other sources (AU) start/Stop, Tempo and position.
