  1. Some good sounds here………….might buy this on the strength of these demos! Nice price as well.

    The look reminds me of M Audio keyboards…….the pads………very nice.

  2. This app is awesome. It’s basically an exact replica of the Korg Electribe 2… but with better sounds. Really hope that they will address many of the e2’s shortcomings in further updates though…. like 8 bar patterns and a chromatic keyboard! ?

  3. Coming from Electribe 2 this is SO easy to understand. Being software, it has the flexibility to address and improve upon that hardware’s shortcomings.

    Totally worth it, if not just for another Electribe to your arsenal!

  4. Lack of Core MIDI is a bit glaring. JimAudio did a really nice job with Poison202 in terms of simplicity and sound quality but this has me dubious.

  5. I own the EA-1, ER-1, EM-1 and ES-1 electribes and love them, but this is a very cool app. Wow, my iPads running so many freakingly good apps for so little $$$, it just keeps getting better and better.

  6. This app sounds great and features the exact kind of functionality and workflow that had me considering upgrading from Electribe 2 sampler to Elektron Digitakt. All of a sudden I don’t feel the need to buy anything new. Runs great on first gen iPad mini too.

    Once this app dev adds in midi in/out control and export of stems (as he plans to do according to audiobus forums), this will be comparable to any of the hardware boxes I’ve been looking at in terms of functionality. In the case of the E2S, it definitely already sounds better. Looking forward to seeing it get better.
