KQ MiniSynth is a powerful polyphonic modular synthesizer.
This app allows you to create sounds by patching modules.
You can add/remove up to 100 modules at will.
(Oscillators, Envelope Generators, Filters, and so on)
Of course, it depends on the capability of your device.
Modular system is also good for education use.
You can learn the role of various modules while patching those.
The Patch-Editing view supports zooming.
You can connect modules with taps easily.
71 Presets are included.
External and Virtual MIDI is Supported.
MIDI over Bluetooth LE is Supported (Act as a Central device).
Inter-App Audio is Supported.
Audiobus is Supported.
Ableton Link integration.
Includes an Audio Unit Extension (AUv3 Instrument).
FAQ:
Q: The output sounds too quiet.
A: Expression value(Ctrl #11) may be too small. Try to Tap "RESET" on I/O Panel. When it is not improved, try changing an option "Boost Velocities".
Q: The velocities seem to be ignored on Audio Unit.
A: If you want to enable the note velocity function in Audio Unit, try to turn off "Ignore Velocities" in the settings. (The default is enable because GarageBand sends velocities randomly.)
