The sequencer is quite deep from what Ive seem so far in my opinion, however it does seem more like an MPC sequencer than say a Machinedrum, and it would be hard to surpass the Machine Drums UI in some aspects.
From what Ive read the Tempest should easily top any other drum machine I can think of and that Ive owned when it comes to the structural capability it offers access to for one voice/sound.
What I find odd is that a lot of people (youtube comments etc) are really praising the sounds theyre hearing, but if I'm honest I havent heard anything fantastic yet. A lot of the sounds weve been hearing are very basic, or just samples, when the specifications of the Tempest show its got real potential for layered and well structured sounds. From the specifications, and some imagination, I think its definitely capable, and if I hadnt just bought an octatrack Id be getting one.
What makes you say it seems like a Jack of all trades though? (not trying to be an ass, just interested) I thought it was quite focused to be honest.
Do you mean feature wise?
