Most options are accessed by sliding the arrow at the bottom right of the screen to the left. Just tap a choice from the list that is revealed
Setting The Key
All the usual major and minor key options are accessable to change the default chord choices ...
In the "chord" mode tapping one of the six chord pads allows selection of a different chord from a very comprehensive list. Sliding the list up and down reveal more than is shown here.
The guitar's tuning can be adjusted up and down in case you're playing along with another instrument that is somewhat different.
Several playing options are avaialble : With 'Fret Muting' toggled on, the strings of the guitar can be 'palm muted' by releasing your finger from the chord pad. Holding the pad restores normal strumming. This is really well done!!
this toggled option reveals two spring loaded trigger bars which slide the main chord pad left or right to reveal six extra asignable chord pads ( in each direction ). The main pad slides back as soon as your finger is lifted from the trigger which I find a bit fiddly. On the iPhone the secondary chord pads can be revealed by tilting the phone. Cool!
Hammer On / Pull Off
A good hammer on can be achieved between any left/right adjacent chords. Not sure why the adjacent-chord restriction exists. Pull offs are trick for me at least...
Toggle this on and the strings move further apart to make picking easier. On the iPad they are too far apart for me. When strumming the strings collapse again to the default separation. That's the smart bit, but moving strings is the last thing I need on a Guitar! This feature is a .99c upgrade and probably more useful on the iPhone version.
This menu allows you re-skin guitarism and take the GUI away from a physical Guitar based metaphor. I hope Rhism isnt afraid to do more with this!
The 4P button reveals awesome MIDI outputs for controlling 3 other intruments plus the Guitar itself. Thats four sources ... mind blown.
