Tyros 2 + NP30 Midi Setup T2. Function \ Splitpoints. Set Split Points R1 & R2 to C1.(last key left) R3 C1#. Previous Registrations saved may alter this. NP30 Midi Out to T2 Midi In A. Only one lead required. (Midi IN B could be used) T2. Function \ Utilities \ Midi \ Edit. Page to System and set Receive Transpose to ON. Page to Receive and set CH1 from Song to LEFT. Page to Chord detect Tick CH1. Volume Control of NP30 is OFF as it's acting as a dummy to trigger T2 Chords \ Styles. The Midi Template settings above Save As (name ?) Suggest Lower ON into USER. I did another Template leaving Receive CH1 to Song and Saved As Lower OFF into USER. This enables you to switch off T2 left voice if not required as on the T2 left voice switch does operate on this setup when playing from NP30. Additional NOTE. Normally the TwinSet NP30 would be playing chords around middle C as per Organ. The NP30 can be transposed one octave down by..... Holding Grand Piano Button down whilst pressing C4. This now plays the T2 Left Voice -1 Octave [GrahamUK]
