Thx a lot, fellow travelers,

Jim -once again- raises an important question: why don’t you make (Real) User tracks?

That is the key question.
In MIDI, the “algorithm” does some of the work for you. In Realtracks, this does not work.

In BIAB you can make styles by making a MIDI song where you have 2 bar-, 1 bar, half a bar, 1-beat chords. If your MIDI file is long enough, say 32 bars and 3 choruses without any copying and pasting, it works. This way you get more than 15 variations for each “case”: 2 bar chord, 1 bar, half a bar... (Most factory styles are not so elaborate and stick with 5 variations, but still...)
Even this “simple” workflow takes me on average 30 hours for only bass and drums and a little piano. One style. Being fed up with hearing the same lines in different styles, as PGMUSIC does, I never use a line twice and that makes it more fun to play along with.

Biab, Yamaha and Roland then have an algorithm that translates chord and scale tones to all possible chords. Yamaha and Roland are scale based, Korg has a really sophisticated algorithm that is scale and chord based. Biab is scale or chord based, but the algorithm only knows a few chords.
A good algorithm should know about 26 different possible chords: 7 modes of Major, Harmonic minor, Melodic minor, 1 mode of wholetone, 2 modes of diminished, 2 modes of Augmented. Roland, Yamaha and Korg do a great job at this, but don’t have a good song based software with lead sheets like BIAB. BIAB is both ahead (song, sheet, melody) and behind (harmony...)

In User Tracks you would, to have a good variety and modern harmony, have to record 32 bars, 3 choruses for every chord type (to make it intresting, you could make songs that overlap, of course...). That is 96 bars times 26 chords... quick math for a 120 bpm style: 10 hours of playing! For each instrument! For each style! And that’s if you played perfectly on each take. And not taking the time to correct velocity bumps, adjusting microphones and all...

That is why all jazz Realstyles share the same sixteen bass parts, piano parts, drum parts. And get boring after some time. Cause you select a different style, but, in reality, you get the same drums or bass...

Algorithms do the work for you. Realtracks don’t have that possibility.
In the future, with stuff like Melodyne, it will be possible to use the same procedure in audio as in MIDI and sound good. It is already possible, but sounds quirky. At this time, harmony-wise, realtracks are at a dead end. Even at the rate of the minimum wage, smile

I think MIDI is a good alternative with all the great libraries out there. If only PGMUSIC stepped up their algorithm.

Biab, Kontakt, Sampletank and lots of nice libraries, from Fluffy audio to Abbey Road drums.
