use your interval list and offset root note.

------- zl objects might get helpful to reorder lists or split them instead of pak -> unpak -> pak etc ----- Transposing like that might produce notes out of midi range, which can cause problems, even corrupt midi port. I would insert clip 0 127 and thin the list

Thanks for your response, really helpful stuff! This technique is superb for transposing, but it's not really what I'm trying to do; I want to be able to transpose diatonically (keeping the relative values within the list, but changing the starting point of that order and generate a new list). I think what I'm after could be described as your example, but quantized to the relative values of the scale fed into [vexpr].

Any thoughts? /J

no, sorry, I have no idea what you mean. can you post one source and one destination list, so that I can try to understand it. 2 2 2 1 2 2 1 are intervals of a scale or distance between list members if you prefer to describe it that way. Maybe I took it wrong because they sum in 12 = chromatic scale and repeated root. and it looked as lydian scale ... 0 2 4 6 7 9 11 If you really mean diatonic transposition or melody shift ... Then simply move each note in a list a diatonic step higher or lower. but for that you need to set the tonality. otherwise we are again in chromatic transposition. if you pick any scale and key then your available notes are given. if what you want is to pick any note and create a list which adds intervals you again end in a scale set 55, add 2 2 2 1 2 2 1 = 55 57 59 61 62 64 66 67 in case that is G lydian scale than your available notes are 1 2 4 6 7 9 11 13 14 16 18 19 21 23 25 26 28 30 31 33 35 37 38 40 42 43 45 47 49 50 52 54 55 57 59 61 62 64 66 67 69 71 73 74 76 78 79 81 83 85 86 88 90 91 93 95 97 98 100 102 103 105 107 109 110 112 114 115 117 119 121 122 124 126 127 same as D major scale

Hey, thanks for the replies. The source list contains of 8 unique list members and I want them to be transposed while maintaining their relation to their neighbouring list members. Source example: 48 50 52 53 55 57 59 60 (C-major) What I want: ...36 38 40 41 43 45 47 [48 50 52 53 55 57 59 60] 62 64 65 67 69 71 72... That is adding an octave above and below the source list, and I've been able to do it using the tips you gave me in your previous post. But, this only works when the source list is within a span of 12 semitones with my current routing (patch attached). What I want is to be able to give a source list spanning over 12-semitones, analyze the relative values between the list members and get a full list of available values between 0 and 127.

Still not making sense? Thanks, J

let's see list is fixed at 8 notes they can be as much apart from each other, even over 2 octaves you want to get intervals of that 8 notes related to 1st or lowest note in the list and build several new lists which keep same intervals from the root. what if list is 22 44 66 88 100 111 123 ? where do you transpose that ? anyway, you first need intervals of 7 notes related to root one. in your first patch list was 50 53 59 62 65 72 79 83 intervals to the root are 3 9 12 15 22 29 33 now what would be your wished transposed list up, and what down ? Or what should even be 1st item in transposed list to build intervals ?

this could make it if that is what you want

you just need to extend it in both directions till limits 0 - 127 are reached ...
