I'd like firstly to record my admiration for Robin Hayward's invention. It opens up harmonic space in a beautiful way.

Here a suggestion that may have occurred to a few users already: it would be possible to introduce, alongside the transpose feature, the ability to -rotate- the vine through harmonic space or, equally, to rotate the harmonic space in relation to the vine.

To explain: I can pick up a cube off the table and rotate it through 90 degrees around any one of 3 axes, so that when i put it down again the corners that are now touching the tabletop are different to the ones that were initially touching it.

Just so, one could add to the software the ability to rotate the represented 9-dimensional harmonic space around one of its axes. The result would be that different pitches -and- different pitch-relationships would come to lie in the main lattice usually occupied by light blue and grey balls and struts.

The first Hayward Tuning Vine workshop took place on 11.10.14 at N.K., Elsenstr. 52, 2. HH, 2. Etage, 12059 Berlin.

The Hayward Tuning Vine may be used

- as a pedagogical tool, for learning about and exploring Just Intonation;

- for performing music in Just Intonation;

- as an interface for composing and improvising in Just Intonation.

It is a Just Intonation alternative to the piano keyboard.

When using the shift arrows, placed left and right of the number boxes, I find it helpful to imagine harmonic space moving through the tuning vine. The vine itself stays static, but the pitches of the nodes reflect the shifts that have taken place.

The shift feature allows the user virtually unlimited exploration of Just Intonation up to prime number 23, whilst enabling pitches to be simultaneously sounded between 20 and 20 000 Hz. 

NB the 'shift' arrows were originally referred to as 'transposition' arrows. This proved confusing as it implied that the pitches were thereby transposed up and down, whereas only their position within the lattice is changed. 'Shift' reflects this changing position without implying that any change in the sounds themselves.

We've been asked if we can include a 'save' option in future versions. Presets will allow the user to save and recall specific patches, rather than having to screenshot them and build them up again from scratch. This is high on our list of priorities for v2.0.
