I can echo this sentiment exactly. I started as a kid with a Yamaha PSR-500 with a built in multi-track sequencer. I wrote SO many songs on that thing. In my teenage years, I added a Boss DR550 Mk2 drum machine synced via MIDI and my song crafting went through the roof! Then I added a Korg M3R sound module and my productivity went down. I added a Yamaha DX7, Korg DW8000 and an Akai AX73 and I was barely doing anything other than noodling around. Even today with all the money I've spent on Arturia VSTs and an M-Audio controller.... a really beefed up computer just for recording. And I've written nothing. It's not for lack of creativity. It's just become such a pain to set everything up and get it going. By the time I've got sound in the headphones, I've just lost interest.
