Some one asked me a while back when we were "discussing" the use of BIAB (I was discussing but the rest were rubbishing) what would Beethoven have written if he had comupters and BIAB etc and I said it certainly would not have been what he is now famous for.
Imagine Lennon and Mcartney with BIAB, what would Yesterday sound like without George Martin's input re strings? Totally different, maybe as good but never, IMHO, beating having 100% human input.
I have written songs since the 1960's but I sounded like a blunt drill bit trying to cut dry driftwood in an echo chamber on just guitar and voice. My first "studios" with 4 and 8 tracks sounded better but this time covered in hisszzzzzzzzzzzz. Then came MIDI and then I discovered BIAB. YAY!! and I now have full instrumentation at my finger tips with VSTi's etc etc.
I would love to be able to write like a classical composer in the 18th century or actually have thought of, for eg, the signature sound of the Glenn Miller orchestra with the sax and clarinet.
Progress has meant that I can now just pick a style, press generate and have a song without any intervention from me inputing the chord sequence. This is what I did with BIAB initially with the inbuilt styles. Now with real tracks a professional sounding song materialises. This is without any input of the "button pressers" ideas for a song, chords etc.

BUT inputting one's own chord sequence turns BIAB into the best band ever, no drunks, no chatting up the wimmin, no broken strings and forgotten leads and best of all no arguing and fights. Been there done that too often, usually a combination of drink and wimmin With work my songs now sound,as near as possible to the version inside my head with a reasonably professional end result. And all at home in my lickle "studio".
The user showcase also shows how good BIAB can be in the right hands BUT I always wonder if those songs would have ever seen the light of day without BIAB and I THANK PG Music for making it all possible. Helping us all, maybe, realise a dream.
Without BIAB I would not have fans in Vietnam and Japan or have been called WIllie Nelson's ugly brother!!!

I was classically trained on piano BUT BIAB has taught me more about music than I have ever learnt from teachers. Apart from that Saturday in the 1970's when Jeff Beck showed me how to play Jeff's Boogie https://www.youtube.com/watch?v=4A_s0Kyh2qQ in a music shop in Charing Cross road, London. He said FFS this is how you do it and showed me hammer-ons and pull offs, cheers Jeff!!!

I say BIAB is now a musical instrument and as with all instruments you need to learn how to play it.
