This is great, thanks and likely to be super useful! But I don’t think it was quite what I was looking for. Put simply, the bottom row of the scale page allows us to increase the pitch of the scale by semitones (i.e. transposing it into a new key) but only allows a shift of up to 7 semitones maximum. What would be awesome would be if you could shift all the way up to 11 semitones. As it stands, if your oscillators are tuned to C (or if you’re using Just Friends over i2c for example) you can use all the keys from C through to G, but none higher than that - which is a bit weird. The workarounds described above involve using a different root note than the “real” root of the scale and changing the other intervals to kind of fake the scale. This works, but is a bit clunky and has other problems (for example, the highlights root note on the Earthsea grid will be in the wrong place). So, what I was hoping for was a way of adding an additional shift beyond the 7 semitones allowed by the grid.
Here’s one possible approach:
Use one of the spare keys on the bottom row as a shift key. Press a key on the scale editor - this lights up, but so does the last light on the row. The pitch shift for this row is then the sum of both lights. E.g. if you press the first light with the shift key pressed, you get the first light and the 7th light lit up, giving a total of 8 semitones.
Does this make sense?
Sorry for endlessly suggesting new features to Ansible - it’s already the greatest sequencer ever, so it does seem a little greedy 
but this feature of only being able to play in some musical keys does feel peculiar and is a bit awkward to explain when I’m collaborating with other musicians!
