### 1/5 — Doesn’t work on iOS 15

*2023-05-17*

Blablabla

### 3/5 — unfortunately still with a crucial bug

*2023-02-08*

when i connect the app to an instrument or an effect in aum, the volume turns up and down at the same time.  With this bug the app is almost unusable.  unfortunately, because your concept is fantastic

**Developer response:** Hello

Sorry for that experience. This happens because default midi output of this app is routed to AUM's MIDI control and it receives control change number 7 on channel number 1 as volume control. You can easily fix that by either changing output channel in lfoch or by disabling cc7 to channel volume in AUM.

As there is a default mapping in AUM for all midi control change 7 messages on respective channels, it doesn't make much sense if i change the default output channel of the lfoch from 1 to any other as it would send cc7 anyway if we have default 16 outputs.
I'll make a special note about that in the description to avoid this confusion and to setup the app properly.

Regards,
Alex

### 5/5 — Lfo lfos Lfo

I use it mostly in Apematrix and get the knobs dancing, very nice laboratory for very experimental sounds!

### 5/5 — Mad Hat LFOH

*2023-04-15*

Trippy idea that can be used in many ways. I love using it with drum synths,  and strange sound effects. Is easy to route through AUM  as well.  Enjoyable interface, cool concept.
