Realistically isn’t the most likely thing just a digital drum synth? Not a sampler, like a machinedrum. They’ve got samplers. Digitakts takt obv comes from rhythm so would be weird to have another unrelated takt in the line. If I were to bet on it I’d definitely just say a digital drum synth. Doesn’t really compete with anything else in the line but prob won’t necessarily be a direct follow up to the machine drum. Just some digital drum synth
