Rollback the clock about 15 years, and I was doing everything with real instruments (guitar, bass, drums, and a keyboard synthesizer). My first primary instrument was bass, but I always liked drums; so I got an inexpensive Pulse drumkit and then for about a year explored drumming and Latin percussion, which included (a) focusing on ergonomics and (b) learning how to tune the drums using the techniques in Prof. Sound's "Drum Tuning Bible", which is stellar.
Before that, I designed and built a sound isolation studio, which is a room inside a room inside another room of my house that sits on piers and is raised off the ground. The innermost room sits atop compressed mats made of ground and compressed truck tires and is floated rather than being attached to the outer rooms. It's heavily insulated and there are air-gaps between the walls and ceilings of the outer rooms, as well as Helmholtz resonating panels and two layers of different-width sheetrock. The innermost room is 6' wide by 7' tall and 12' long, which makes it approximately the same size as Les Paul's recording studio before he became famous and started recording himself and Mary Ford in their house.
As shown in one of the photos, what I now call the "Really Bigger Drumkit" nearly filled the sound isolation studio; and I had a lot of microphones on it. The microphones ran to two submixers and then to a larger mixer and finally to a MOTU 828mkII external digital audio and MIDI interface which I connected to an Apple iMac and later to Apple Mac Pro computers, although now I am using a 2019 Apple 27" iMac (Intel processor, 4TB hard drive, runs everything including macOS Sonoma, and cost approximately $1,000).
The "ergonomic" aspect maps to stacking cymbals and Latin percussion instruments; using double-action foot pedals; and custom 22" drumsticks that I make from 5/8" oak dowels, where the strategy is to make it possible to play several things with one upward or downward motion of a drumstick or foot pedal.
At the time, I was not getting good mixes, which was puzzling; so I called MOTU and spoke with "Magic Dave" who provided four very important insights: (a) the submixers and mixer probably where not impedance-matched, (b) the sound isolation studio was no bigger than a walk-in closet, hence having 25+ microphones was not the brightest idea, (c) use two microphones and run them directly to the MOTU 828mkII and stop using the mixers, and (d) that anyone who can play the same instruments as the Beatles reasonable proficiently can sound exactly like the Beatles if they practice the song about 1,000 times.
It all made sense, and most importantly it worked.
The advice about sounding like the Beatles was in response to my saying I can play all the instruments in early-Beatles songs, but it was not sounding so good. Overall, the "1,000" times matches some of what the Beatles did, at least with respect to playing songs over-and-over to get everything perfected and sounding good.
Another completely and totally strange bit of advice perhaps a decade earlier was from a recording engineer in Hollywood who told me that for the "R.A.M." album, Paul McCartney did everything on the first or second take, which I misunderstood literally to map to everything (instruments and singing), when as I learned a few decades later was referring only to McCartney singing a few harmony parts on one or two songs--not on everything.
Among other things, this led me to do what initially was a frightening experiment where I imagined I was teleported with my Marshall stack, effects rig, and Stratocaster onto a stage at an Elvis Presley concert at which time a spotlight shone on me and Elvis looked at me and said "Take it", meaning I was support to play a lead guitar solo for a song I never had heard other than a handful of measures.
Considering that I focused on imagining this to be very real, it was frightening; and during the early days I was afraid there would be knock on the door and two FBI Special Agents would arrest me for being "too spontaneous", since I composed and played everything in real-time on the fly, thinking that if Paul McCartney did it, then I could do it.
The "Fabulous Fifty Million Dollar Trinaural Stratocaster" is a custom-modded 1999 Fender American Deluxe Stratocaster that has two separate and independent output signals--two channels but not stereo--and took about a year to mod, since I had to make sense of all the components and do the guitar-body routing.
The entire thing is real, and it happened; and it's one of the consequences of being very smart in some respects but basically stupid in other respects, which is best explained by my getting stuck for a year or so when my goal was to teach myself how to play lead guitar. I eventually had an epiphany, was is that with a few rare exceptions, every lead guitar solo of the 20th century was played by someone who had four fingers and a thumb on each hand, excluding Django Reinhardt. Once I had that epiphany, playing lead guitar was just a matter of moving forward and taking the time to rewire my brain and improve my muscle dexterity, where the "rewire my brain" aspect refers to creating new neural pathways between the frontal eye fields (FEF) region of my brain and the auditory cortex, where the former has response times as rapid as 24 milliseconds and the latter is more in the range of 60 milliseconds. This also keyed on the fact that you cannot think about everything in an immediately conscious way, because it takes too long; hence you need to discover how to suspend most immediately conscious thinking and to let your unconscious mind run the show, which curiously is one of the best ways to overcome the fear of being arrested by FBI Special Agents for being "too spontaneous".
With all this in mind, once I switched to using VSTi virtual instruments and music notation, I moved the Really Bigger Drumkit to another room and built some plywood benches for the computer, an external rack, and Kustom studio monitors, which actually are loudspeakers for small nightclubs and in a walk-in closet are sufficiently powerful to be excellent studio monitors when calibrated at 85 to 90 dB SPL with a flat equal-loudness curve running from 20-Hz to 20,000-Hz and a dBA weighting.
Sometime later, there was a lightning strike and one of the Kustom two-way PA units exploded and burst into flames; so while I had some spares, I retired the studio monitor idea and switched to using SONY MDR-7506 headphones instead, which by that time was practical since I had discovered how to get good levels using the studio monitors and just applied the same rules to mixing when listening with the headphones, since along the way I would work with the studio monitors and switch to headphones and vice-versa, hence had a good sense of how everything worked. There is more to it, including the way people hear sounds, as discovered by researchers at Heidelberg University in Germany, but I explain that in my books of digital music production.
Regarding calibrating the Kustom PA units and subwoofers, I wear OSHA-approved ear protectors like airline workers wear on the tarmac when airplanes jet engines are running. Basically, you set the computer and external digital audio and MIDI interface to their maximum volume levels and then gradually increase the volume levels of the respective self-powered Kustom PA and subwoofer units until pink noise is 85 to 90 dB SPL measured with a dBA weighting. Explained another way the Kustom units have the real and tangible potential to be louder than two Marshall stacks (full), which in a walk-in closet would result indisputably in permanent ear damage or deafness, hence is something I can do as the result of running concert sound and understanding all that stuff, but is not something I generally recommend for everyone, where my recommendation for everyone is to use a pair of PreSonus Sceptre® S8 two-way monitors and a pair of PreSonus Temblor® T8 subwoofers, where I recommend two of the subwoofers so there is one for each channel of stereo instead of trying to save a few dollars by combining the deep bass arbitrarily, which for practical purposes maps to an electronic device or processor doing the deep bass mixing instead of you doing it.
Summarizing, my current setup is to do everything with the 2019 Apple iMac (Retna 5K, 27-inch) and a B.L.U.E. Snowball USB microphone, along with Studio One (current version), music notation, and a virtual festival of VSTi virtual instruments and VST effects plug-ins, along with Reason (Reason Studios) via the Reason Rack VST and the standard assortment of PreSonus native instruments and effects that are included with Studio One, as well as AI voices from 11ElevenLabs for voices to expand what I can do with my voice-overs in my ongoing science-fiction radio play "Extreme Gravity", which now has 27 chapters, all with music and online at my YouTube channel.
It works nicely, and I think the audio sounds good after YouTube does its proprietary processing.
[NOTE: These sound good when played through studio monitors and computer loudspeakers, but they are mixed for listening with studio-quality headphones, which is the best way to enjoy them. I like SONY MDR-7506 headphones, because (a) they are sonically neutral but (b) have excellent deep bass. I did the first one ("Billie Jean Intro") to show three ways to do panning: (a) Instrument Track true monaural panning with Dual Pan (PreSonus), (b) Audio Track true monaural panning, and (c) simple balance control "panning", which is not true monaural panning but is ballpark when the two channels of the sampled-sound library are nearly identical. ]
