Hi, Spacey. Hope you've been well.
Gonna blather about this (as usual) because my brain needs a five minute break from learning webdesign crud.
Anything I've been able to keep over the years I have. That includes stuff I did in Nuendo (way before I became a Sonarite) and I even have some tracks from sessions done in studio with my old band which I came across as a fluke (but unfortunately didn't get the tracks for the previous album I did with that guy which were deleted and the tape/HDD space reused... ugh... but that was released so whatevs).
The studio sessions I do have were actually pre-production for an album that has yet to be release almost a decade later due to member changes and lots of other stupidness and now the band isn't functioning anymore. We did attempt to redo it all with fresh beds with new members but after endless work (on my part) doing all the overdubs, mixing, etc the band decided it sucked because the beds were bad (too slow, no life, bad drum room, we were to old and jaded, etc). So now I'm looking at that first pre production session as a foundation for the album and man am I glad I have them otherwise those songs would be lost forever aside from some crappy live bootlegs. I've imported it all into Sonar and am going to tighten it all up so the timing is a little better, overdub a lot of stuff (but keep as much as I can of the original tracks) and basically turn it into a studio album ready for mastering/release.
As far as my Sonar efforts... yeah so far I've kept everything but I don't really have much. Basically three full original productions. They were just tester tracks to learn the program really and I've posted all of them on the songs forum but I think maybe they could be interesting releases if I redid or heavily reworked the originals. A lot of mistakes were made and frankly I find the content a little more boring than I'd like but with some work they're passable. People here seemed to like them and apparently they're being bootlegged/stolen on sketchy foreign music stealing sites (but those may just be internet scrubbers and no actual humans decided to steal them).
I don't particularly like having all that stuff eating up HDD space though so what I'll probably do is find some cloud storage solutions and/or just archive the files on DVDs locally. It's always fun looking back on stuff and you never know what will come in handy later on. There is one song in particular (my first real guitar song with Sonar) that I think is REALLY cool but it was actually a test of BFD Eco that evolved into a metal shredder. I had basically just gotten Sonar and BFD running and understood the basics but did not realize BFD Eco as standalone would not export as MIDI. Only a stereo audio file. I had just strung together a bunch of cool sounding pre-programmed content (beats, fills and whatnot) using BFDs timeline thinking I could get the MIDI file for it... which I couldn't. So I just dragged the resulting audio into Sonar and wrote a song around it. This severely limited my drum mixing/editing options. I'd like to try to recreate it (by hunting down the same loops I used), use some of the original guitar work with some overdubs, redo the bass and try to extend the whole song (which is under two minutes). Then obviously I'd like to mix it properly because back then I had absolutely no fracking clue what I was doing so the original is very dull sounding.
I may however just remix the current version and call it a day but I think it has a lot of possibilities both as a song and as a learning experience in fixing stupid stuff.
The other song that I've pushed way more on here (because I used more proper methods to track it) I find is actually a little lame musically but with some more interesting drum/bass parts and some fiddling with the composition it might work.
Anyway... I'm a lunatic who has all sorts of other weird ass plans for stuff like this that go beyond personal enjoyment or traditional releases so go with whatever wets your whistle, dude. Sounds like you want to take another crack at it so have at 'er even if it is just for the nostalgia... which is a great motivation IMO.
Cheers.
