New App, Pepp, A ‘Twisted Groovebox’ For iOS

pepp-smallDeveloper Patrik Hedmalm has introduced Pepp – a new iOS music app, described as a sort of ‘twisted groovebox’.

Here’s what Hedmalm has to say about Pepp:

This twisted groovebox/arpeggiator/synthesizer lets you quickly forge original electronic music, using sixteen sliders and a sixteen-step sequencer.

Instantly save and recall your ideas without missing a beat. With 160 memory slots you’re not likely to run out of storage.

While it’s designed to be easy to use, Pepp also offers:

  • MIDI support, including playing via a MIDI keyboard, MIDI sync & MIDI control of parameters; and

  1. Like the ability to try limited feature before going full blown, lets you have a feel to see if it something you can use.
    Be installing in a few to try out

  2. I bought it. I see how I can make use of it and it’s fun to jam with. I think this will be one of those “love it or hate it” apps for most users. IMHO of course.Try the free demo. IAA and AB BTW.

  3. Curious to see if the IAA will work effectively and effortlessly with Cubasis. Just downloaded the trial version. We’ll see how that goes.

  4. I downloaded this after the trial and playing with it a solid 10-15 min. and I think with IAA and Audiobus I could produce some impressive tracks with this. Kudos to the developer.

    1. Doesn’t work on iPhone 5.
      There is a help splash window when the app opens that doesn’t fit in the screen. As if it wants to be used by a bigger screen of say iphone 6. I can’t get rid of the pop up screen at the beginning and therefore can’t use the app

  5. Pepp is a terrific , but addictive app. It looks, works and sounds great on an iPhone 6.

    In my short session with it, two of the stand-out functions are the excellent filter and reverb. The filter sweep is smooth and the reverb is deep & clean.

    Highly recommended!

  6. I have never ever seen an app wich can make so sweet melodies! Try and send MIDI to it via Wi-fi and it starts to make some serious melodies!! Great stuff!!

  7. Downloaded the free version. After reading these comments I really feel like I’m missing something here; So far I’m just tweaking somebody else’s sequences. Where do I create my own sequences? Is that a feature reserved for the purchased version? I don’t mind the defaults, but I’m only interested in creating my own.

  8. Congratulation This application is very easy and creative . It would be so nice to add the Ableton sync link ?? if it is possible
