## What is Blip Box?

Blip Box is a sixteen voice drum synthesizer that may look nice but can sound mean. Blip Box takes inspiration from a variety of synths, both analog and digital. We pulled together all the things we love about drum synthesis: complex audio rate modulation, snappy envelopes, harsh effects; and put them together in a compact, touch-friendly package. The result is a truly unique digital sound engine that has taken on a life of its own.

Whatever you do, don’t have fun with it!

### 5/5 — I really like it.

*2026-06-23, version 1.0.2*

Some sounds remind me those in Korg Volca Drum, which I really like. I’ve had it for just a few minutes but I already know it’s a great app. Nice interface, very easy navigation. It is immediate. The sounds have a bit of imperfection to them, sometimes a bit of buzz, sometimes some distortion, which makes them more pleasing to the ear.

### 5/5 — Sounds beautifully synthetic.

*2026-06-10, version 1.0.2*

Sometimes real acoustic drums aren’t what you want.  This has lovely artificial hits, good stuff.

### 4/5 — Amazing sound, minor limitations

*2025-12-30, version 1.0.2*

Absolutely love Blip Box, the sound quality and sculpting tools are great! 

My only qualm would be that as it can take a long time to create sounds, often I’ve lost any spark by the time I have made a kit. Sometimes I want to boot up and play around with whatever a drum synth has spat out.

With limited built-in presets and not many people sharing presents online, it would be great if we could randomly generate presets or per-pad sounds? This would be a great addition

Thanks Sketch Audio for the great work!

### 5/5 — Not a Simmons Drums emulation, but something possibly more interesting

*2025-04-17, version 1.0.2*

Yes, you can get very close to the classic Simmons Drums sounds from the 80’s, but this kit has a bit more going for it. Built in options for extreme distortion, for example, can get you closer to a Nine Inch Nails sound if you like. Deceptively simple to use, but loaded with creative possibilities.

### 4/5 — Not Happy

*2025-02-24, version 1.0.2*

Was really expecting something more than this. As basic as it gets. Reminds me Commodore 64 sounds and wasn’t expecting that for the money. Would take a refund if possible

### 4/5 — 🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨

*2024-11-26, version 1.0.2*

Can you Please add more seconds of holding down the button to pull up the options on the pads or use a two finger tap to activate it…. It’s very annoying accidentally activating the pad menu.

### 5/5 — Best drum synth going

*2024-11-20, version 1.0.2*

This is my favorite drum machine app. The AUv3 support has led me to use it on pretty much every track. I genuinely love it. It is fantastic value, especially since you can use it on your MacBook without paying twice (I’m looking at you, baby audio)

### 3/5 — Great sounds, but only 13 presets and no random option

*2024-07-07, version 1.0.2*

Nice UI, really good sounds, and works well as an AU. However, it does take a while to create a new sound on each pad, and as there’s no copy and paste (or drag to copy sounds to each pad), it means starting from scratch each time. And there’s only 13 presets (though you can save your own). A randomiser is essential for this sort of app, as it produces ‘happy accidents’, and starting points for your own ideas. I would use this app much more with a randomiser feature, as it is its going to take a fair amount of time to build up my own library of presets.

### 4/5 — One problem here...

*2024-07-06*

The digital drum sounds are pretty cool and the app has very easy to use and understand controls. Also, the fact that your one-time purchase works on iOS, iPadOS and macOS is a huge plus. BUT the pad assignments do not follow the General MIDI Drum Map, so the app cannot simply be swapped out with a normal drum plug-in. This is not great for productivity in a production environment. Other than this, I love this thing!

### 5/5 — Love this app

*2024-04-08, version 1.0.2*

I’ve had this app for a few months but am only now really delving in and sculpting sounds and I have to say, having just sold my Syntakt, this makes me feel like I’ve lost nothing, it’s so much fun.
I can’t seem to map any parameters to the modulator in Logic Pro (iPad) but other than that this thing is amazing.
