## Most critical reviews (7 lowest-rated)

### 1/5 — I agree, doesn’t show up in AUM

*2020-12-02*

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

### 1/5 — Does Nothing

*2019-10-17*

It opens a PDF and then does nothing.  I tried uninstalling, reinstalling - no.  It cannot be found by ‘AUM’ and frankly, if that can’t see it, I won’t trust it to be any good.  Why don’t these arrogant programmers put SOME sort of interface for the user in there?

**Developer response:** 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.
This is how AU apps work - they need a host

### 3/5 — Question

*2024-03-08*

Just wondering why on Open it presents me with the manual in pdf and not the app? I deleted and reinstalled and it did it again

**Developer response:** If you open as a standalone app(i.e. just click the app icon) it opens just a window showing the manual). You need to open Polyphemus as an Audio Unit in a suitable host - like AUM or AudioBus to get the function screen

### 5/5 — Brilliant unique app, key to my workflow

*2023-01-25*

Polythemus has become a key component within my workflow, where I need certain notes  from constantly changing chords to be sent to say an arp, others to maybe a pad, the lowest note to a drone etc. This stable app gives me exactly that control and as far as I know it’s unique in that regard. Different note handling policies exist to address different scenarios making it flexible. Superb and powerful tool, top marks!

**Developer response:** Thank you for your review. This app was designed to provide the polyphonic ability to monophonic apps by running multiple mono(or poly if you wish) apps as voices. This app then controls the voice allocation.

### 5/5 — Works as advertised

*2021-02-20*

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!

### 5/5 — Good fun

*2020-07-31*

I wasn't sure i needed this but I've just bought it and it's great fun. Having each note of a chord sent to a different midi channel, and then applying different effects to each note, produces interesting and unexpected results. Nice to play around with for a noodle, which will hopefully become something usuable in an actual track.

### 5/5 — Polythemus teaches old synths new tricks!

*2019-12-09*

As soon as I got Polythemus, the first thing I did was to load it into AUM and send it to 4 instances of Viking synth, then trying it with Cyclop x 4, with different pan settings for each voice. Mind blown instantly!
If this was as far as I ever got with this app, I’d be very happy, but I know it can do so much more!
