bugs:

• 3D view repeat FHPs
• gp8 import hand shapes
• error checks for wrong fhps for handshapes
• gp5 import triplet feel
• bend gp5 import positions
• midi bass
• check tempo moving notes
• After accidentally linking the previous note to a chord at the start of a handshape (which removed the chord) when I recreated it, the notes behaved like individual notes and not like a chord. No matter what I tried I could not get it to properly treat it like a chord again. This caused it to display odd in both the 3D preview and in Rocksmith after building the project.

formats to add:

• psarc

3D preview:

• exploding notes with shaky camera
• arpeggios colored note shadows
• editable camera settings
• camera more like in RS
• string vibrating when plucked

Future things:

• Campaign/Guitarcade
• NAM support/integration (Neural Amp Module)
• Local/Online Multiplayer
