Heavy working for 15 years with KB and mouse only...tried once to use fancy MIDI controller...spent several hours of programming simple drum pattern, then did the same with mouse for 10 mins and threw MIDI controller away. Since that never touched it again.
BTW...watched a lot of Future Music "In The Studio With..." videos and never seen that anybody uses a MIDI controller (im not talking about MIDI keyboard) in serious production...
I have never seen an artist who is in "serious production" who simply uses a compter, mouse and keyboard... Ever.
Im not trying to start a war... But two things im perplexed about your statement...
1: If it took you several hours to program a simple beat with this anonymous "fancy midi controller"... As the kids say these days "YOUR DOING IT WRONG". Or you simply lack the patience to learn a new piece of hardware/software.
2:"BTW...watched a lot of Future Music "In The Studio With..." videos and never seen that anybody uses a MIDI controller (im not talking about MIDI keyboard) in serious production..."
What you might be missing is most of these artist in "serious production" have hardware... And are generally not "in the box" exclusively but aside that point Richard Devine, Mark Ellis, Trent Reznor, Cevin Key, Ralph Hutter, James Murphy, the Dewaele brothers, to name just a few do not simply use a mouse and keyboard... Be it a controller which bridges the gap missing between software and hardware with one of the major missing elements... Tactility and the relationship one develops with and instrument or piece of hardware that cannot be replaced with a keyboard and mouse... A control surface or controller does just that.
Hardware enables the experimentation process be it something complex like the monome for doing things that are not really possible in avante garde way or simply being able to tweak multiple parameters on an synth, eq, compressor or fx processor that are not linked via some type of macro(which is not the same, lacking the human and random element)
There is a vast array of experiences and happy accidents a keyboard and mouse can never provide, or duplicate that tactile hardware provides.
It sounds like you have taken a defensive postion because for what ever reason you dont have controllers.
It's one thing to say one does not need such to make music, but I cant recall the last studio I have been in in the last 10 years (or more) that didnt at least have a digital SSl with motorized faders... which IS a hardware controller.
I would concede you may be able to find professionals whom are 100% in the box with no controllers... But they most certainly are the exception to the rule... Not the other way around.
I would certainly love to see some of these videos of 100% in the box no controllers producers and musicians... I havent seen it and I have a sneaking suspicion if you go back you will find most if not all are using more then a keyboard and mouse somewhere in the workflow in the "serious production" end of things.
Again I'm not trying to start a war with the generation or those who have the personal preference to not utilize technology available but the assertion that professionals prefer working without tactile contact is not accurate... even remotely... which again... one is not required to adhere to standards or the consensus of a "professional" environment to make or mix music.
