### 3/5 — It's aight

*2023-03-11*

It's good but I can't change the preset like it shows in the vids😐

### 2/5 — Crashing on iPad

*2022-12-11*

The app is fine for the most part, and I love my ESX1, but the app drops all sound randomly. Sometime can go 5 minutes, other times only 1 minute before loosing sound. Please fix this.

### 5/5 — Review

*2022-11-27*

It was good but it wasn’t really need the number sounds

### 1/5 — Not updated anymore 😌 a $20 new app instead, seriously ? 😡

*2022-06-18*

Elektrospit has no more focus on this app, they suggest to buy their new Poly app for 20 bucks which is a bit expensive app for what is supposed to be an accompanying app to their great but not so cheap electronic talk box. I like the Elektrospit but I don’t understand this type of customer support strategy. Will we have to pay each app update every year ? Making an app polyphonic is nothing hard, just update your og app.

### 1/5 — SCAM

*2022-03-17*

It's true, I didn't believe the other reviewer but you can't even open this app unless you own hardware. What a waste of time. It's called a voice synth but it's not. It states the minimum requirements as being just an iphone etc, no special hardware listed.
Well done Apple for letting this one through the net and onto the appstore.
Instant delete, obviously.

### 5/5 — Almost perfect !

*2022-01-07*

At first use, all seems ok.

### 1/5 — Another Trap

*2021-12-07*

Software won’t work without $500 of hardware

### 5/5 — Amazing app but needs a few more controls.

*2021-02-02*

I loooove this thing but I do wish I could vibrato the jam strip

### 1/5 — Worked with my last phone

*2021-01-31*

I payed for it, and now when I click the app it just goes back to the phones main menu..

### 5/5 — Excellent App!

*2020-05-10*

Very straightforward and well constructed app! Highly recommend!
