Pico: User Scales - Anyway to Change the Key Order?

Most Recent

written by: Tones2

I tried it and got it to work! The ACTUAL major scale formula for get a vertical major scale starting for the upper right is this:

[major vertical RL]
intervals=0 2 4 5 14 16 17 19 7 9 11 12 21 23 24 26


and to get it starting from the upper LEFT (which seems more natural for piano playing) is this:

[major vertical LR]
intervals=14 16 17 19 0 2 4 5 21 23 24 26 7 9 11 12 -1

Like fzzy said, I'm not sure why you need the -1 here, but without it, the last note on the left side (L8) always will play the highest note of the scale.


And here are some other vertically aligned scales fo anyone who would like to just cut and paste:

[natural minor vertical RL]
intervals=0 2 3 5 14 15 17 19 7 8 10 12 20 22 24 26

[natural minor vertical LR]
intervals=14 15 17 19 0 2 3 5 20 22 24 26 7 8 10 12 -1

[harmonic minor vertical RL]
intervals=0 2 3 5 14 15 17 19 7 8 11 12 20 23 24 26

[harmonic minor vertical LR]
intervals=14 15 17 19 0 2 3 5 20 23 24 26 7 8 11 12 -1

[major vertical symmetrical RL]
intervals=0 2 4 5 12 14 16 17 7 9 11 12 19 21 23 24

[major vertical symmetrical LR]
intervals=12 14 16 17 0 2 4 5 19 21 23 24 7 9 11 12 -1

The last two repeat the root note of the scale on the bottom key of the lower row so that the keys are have the same notes per row, one octave apart. This has the advantage of being more intuitive, but you lose a note in the process. In all cases, I REALLY wish I can use those two scroll keys as playing since my hands are no longer locked in the thumb hook position and I can really use those two notes - and I NEVER use them as scroll keys since you have to see the screen anyway so you might as well use the mouse which is 100 times easier (which was a very poor default setup decision for an instrument which already has limited playing keys).

Besides being easier to play counterpoint, I like these vertical positions because I can visually see intervals linearly for chord formation and keep the same triad shape moving down the columns for the first 4 scale chords at least.

I'd love to be able to rearrange the sequence of the keys in some way - i.e. I'd love to have keys R1 through R8 move up a scale and then continue up the scale with L1 through L8 (of course, I'd love to be able to use L9 & R9 as well, but that's another story, he he). The reason for this is that it's difficult to play counterpoint on the Pico because my hands get in the way of each other, and it would work better if I can seperate the each of the two "vertical" strips as a continuous sequence of notes that would give me more flexibility in keeping my hands apart.

I initially thought I could possible do this by defining a user scale that was out of sequence. and continued above note 12. For instance, using a chromatic scale as an example, I could have a scale defined as "1 2 3 4 9 10 11 12 5 6 7 8 13 14 15 16". But it appears that the order has to be from high to low and that you cannot go above note 12 in a scale.

Can anyone see any way of doing this?

"Yeah... that seems to be the 17th note bug I mentioned in my post... If you add a garbage 17th note to the scale it fixes both of your examples.

[inverted major]
intervals=26 24 23 21 19 17 16 14 12 11 9 7 5 4 2 0 -1

[inverted major isometric]
intervals=26 24 23 21 12 11 9 7 19 17 16 14 5 4 2 0 -1

I'm loving the inverted scales, it definitely feels more natural to me. Thanks!"


I just found the above post in another thread so it actually looks like the reverse of this would be exactly what I was looking for - i.e. the following:

[major isometric]
intervals=0 2 4 5 14 16 17 19 7 9 11 12 21 23 24 26 -1

.......or better yet, give the left hand the lower register:

[major isometric inverted LR ]
intervals=7 9 11 12 21 23 24 26 0 2 4 5 14 16 17 19 -1

I'm not at my Pico right now but I'll try later to see if these work.

I'd love to replace the "-1" above with two numbers that represented the 17 & 18 keys, but I assume that would not work. But heck, I'll give it a try anyway, he he.

Yes, you can assign any note to any key by defining a scale which has 16 notes in it. The 17th garbage note is not always needed -- this appears to just be a bug. In my experiments, scales where the low notes are at the top of the pico, like the default scales, do not need a garbage 17th note at the end. It seems that only in the case of inverted scales is the garbage note needed.

Here's an example chromatic scale where the notes ascend the right side and then the left side. No garbage note needed.

[right and left]
intervals=0 1 2 3 8 9 10 11 4 5 6 7 12 13 14 15
