My Dad and I are looking at getting back into playing live music. However, since it would only be a duo, maybe one other person, we've been looking at using a sequencer/sampler to fill in our other instruments, including drums at this point. We both are pretty inexperienced when it comes to sequencers, but I have learned quite abit about them lately.
Well... Fusion can do all that but you are basically gonna have to get your head round it all and how Fusion does things - basically, you have a new instrument in fornt of you that you're just gonna have to learn (much like if you'd bought ANY workstation).
It's difficult (if not imposible) to give rough guidelines - the best thing is probably to ask questions if/when you're stuck on something. There's a lot of experience here to help you.
Most (if not all) workstations are pretty complex beasts these days and so take some learning. The manuals are all almost universally disappointing so the best thing is to just work through the keyboard (with the manual close at hand perhaps for reference) and take things bit by bit.
For sequencing, don't try and create a masterpiece immediately... just potter around with it to get a feel for things and keep doing that until you get more familiar with it.
The process is not unlike learning a new piece on - say - piano. No-one in their right mind sits down in front of a new piece and expects to play it perfectly first time... you plod through it, make mistakes (get it totally wrong!) but bit by bit, you work through it, get familiar with bit by bit until you can play it with ease.
And so it is with Fusion (or any similar product) - you have to learn it bit by bit until you can achieve things with ease. Unfortunately, a lot of people these days expect to sit down in front of a new piece of gear, press a few buttons and wonder why they've not made a hit record within 5 minutes of unpacking it for the first time!!! Hmmmmm....!!
Take it slowly and quietly, try things out and ask questions here - you should be ok.
Good luck.... and have fun!
