So, going by what you've said about the free version of Studio One, and feel free to correct me, but it won't support the plugins either for AmpliTube or EZdrummer? Meaning I couldn't record a guitar or drums from either of those programs into Studio One?
[edit: obvs you could still try out S1 Prime with your guitar though bcs there are some FX bundled within S1 Prime that you will be able to patch your guitar through, I cant recall which FX they give you but it will tell you on the Presonus site. It might also be possible to record the output from your standalone ezdrummer and pull that wav file into a track within S1, that's far from ideal as it will be set in stone then but it would give you a starting point for trying things out. You'd have to google if thats do-able.]
So, just stick with these KRK Rokits I got for just over £300, and bundled with a Focusrite audio interface?
Guess I could just use my other laptop for working out ideas. Just get the free version of Studio One and mess about with synths and that...
When you look at MIDI keyboards btw I recommend getting one that has some assignable knobs and/or sliders - these can be mapped to the virtual knobs and sliders of synths and mixer in the DAW. Its a lot easier when you are recording to have a hardware knob to twiddle than trying to use a mouse to do it, especially if you've got a guitar strapped around your neck. Also you need to consider how much physical space you have available - Ive got a M-Audio Oxygen-25 but its only two octaves so I often have to push a button to shift the playing range up and down to select the octaves it maps to. If you've got the space in your room you could opt for a wider keyboard with more octaves, eg 4 or 5.
Oh, and I might as well ask, since you mentioned speakers. Don't know if that pic is clear enough? But see the volume and level controls, what the best decibel level to have those at, for the more high gain amps, like Mesa Boogie? Or just generally speaking? Or would figuring out how to set the noise gate threshold in AmpliTube resolve the clipping issue I'm getting with the volume?
FWIW I have my speaker volume pots always on full and I control the actual listening volume using the volume control on the audio interface box. Box shows a red LED if there is clipping from my guitar into the audio box. Everything else is inside the software so I just check none of the levels go into the red.
