Please note: this is an AU midi effect so you need a suitable host(e.g. AUM) to use it. The standalone version is just for the manual

Polythemus AUv3 Midi was created for five main uses:

• Creating a polyphonic synth from individual monophonic synths

• Stacking different or similar synths that play alternatively for variation

• Interesting variations in timbre & rhythms by having multiple synths driven with a sequencer (e.g. Quantum) or arpeggiator

• work outside IOS on hardware synths

• voice allocation of externally hosted software vst(e.g. Logic or Ableton Live) using mac osx IDAM for direct device to mac midi

Polythemus turns your midi chords into mono midi channels so you can allocate polyphonic notes (i.e. chords) into different synth patches.

Load up multiple mono synths to turn them into one polyphonic synth.

Add variation to sequences and arpeggios by varying synth patches slightly or even extremely.

Individual control on number of voices and quick mute/unmute per voice.

Midi velocity scaling per voice for volume balancing.

Transpose midi output per voice to allow more compact keyboard playing & voice balancing.

Option to use just one midi output with midi channels for hosts that don't yet support multi-output midi effect apps.

Universal app for iPhone & iPad devices
online manual here:

Polythemus requires an AUv3 host that supports midi effects (like AUM) - the standalone version contains the manual

Works as advertised

This shows up just fine in AUM and works as advertised. The ones giving this a low score because they don’t know how to use AUM are just sad.

Used it to set up a session using the SWAM solo horns, which are monophonic instruments, so I could play chords. Simple and fast!

I agree, doesn’t show up in AUM

This is not currently usable, don’t buy it.
