  1. Really nice. Would be interesting to hear a comparison with other vsts, e.g. hex drum. But great idea that they make the source open, so there’s no chance of abandonware.

    @Mods, Sorry to split hairs but in the first paragraph I think the pads were hexagonal rather than octagonal.

    1. It’s like Mutable Instruments’ products – commercial, but they give away the source so that you can adapt it to your own purpose or build something new with it.

    1. Yes, I agree that OneTrick Simian looks a lot like Oblivion Sound Lab’s Hex Drum.

      You’re not the only one to notice it, with the horizontal sectioning of the different kit. Remove the colors and the different is more striking.

      Hex Drum is NOT based on the original SDS-V, so as a point of derivative-ness, Simian definitely feels like a tribute/knockoff depending which way you want to take it.

      I asked them and they haven’t replied.
