### 1/5 — NO BLUETOOTH!!!

*2023-01-31*

App doesn’t work over Bluetooth so if your device doesn’t have a headphone Jack you’re gonna be stuck listening to it over the phone’s speakers.  I have reached out to the developer several times but have been ignored.  They obviously don’t care.

### 5/5 — Fantastic

*2018-01-16*

I use this constantly. Love the sound. Easy to use. Good presets you can tweak.

### 5/5 — Been using this since 3Gs. Still awesome!

*2015-12-15*

Sounds great! Connection with other audio apps is a nice touch. For example, record performances in Garageband. The tape recorder is great too for quick ideas. This app has worked well ever since it first came out. Great job!

### 5/5 — Yah mon

*2015-10-24*

Loved it when it was free, but still worth some dough (since synth sounds seduce senses)

### 5/5 — Professional Grade Synthesizer!

*2014-07-22, version 5.3.1*

This app is easily comparable to any actual synth I have owned or played in terms of sound quality and customization. The possibilities are endless with options to change keyboard size, record ideas straight on the app, store custom made sounds and I couldn't imagine the countless amount of tones and noises to create. Once I figure out how to control it via a midi output device, I will truly unlock this apps potential. Has not crashed on me once and has shone new light on what is possible within the realms of a smartphone app.Recommended to all folks looking to make some serious tunes or just have some serious fun! For the price there is absolutely no going wrong.

### 5/5 — The best app ever!!!!!!!!

*2014-06-26, version 5.3.1*

This app is one of my favorite types of keyboards!!!!! It has awesome demo on it :) I say get this app for an awesome synthesizer. NLog MIDI Synth again is the best app ever!!!!!!!

### 5/5 — Amazing with Line6 MIDI Mobilizer

*2014-04-12*

Love this synth but wish the "tape" function didn't crash everytime with this latest update -__-

### 5/5 — Venerable synth app with vintage sounds

*2014-04-10*

nLog MIDI Synth is apparently one of the older synthesizer apps on iOS, and was appreciated long before the days when AudioBus came around and iDevices turned into portable, amateur music studios.  Fortunately, the developer has kept with the times (this review after an April 2014 update), and we're left with an app that is AudioBus, Inter-App Audio, and Virtual MIDI compatible.  The synth presets are more in the vein of the keyboards from the 1980's as opposed to the more modern atmospheric noises or arpeggiated sequencers, but I actually appreciate that.  It's cheap, it's compatible, and it's still darn good.

### 5/5 — Tiny Mice

*2014-02-25, version 5.2.3*

Errant Ways

### 5/5 — Great synth!

*2014-01-25, version 5.2.2*

Lots of excellent sound patches, regular updates with fixes. Audiobus and Inter-App Audio make this a great buy.
