MIDI Keyboard:

Preferably a Studiologic numa compact (1st version): http://www.studiologic-music.com/products/numa_compact/. 

This is the only model that can currently be used for the piece. (Studiologic numa compact 2 and 2x won’t work.)

Sound:

• 4 ch output from 2 laptops on stage.

• Amplification (2 ch?) piano

• Stereo PA (preferably not floating too high)

• 2 speakers under/next to piano

• Small mixer at a suitable location in the hall for live mixing.

(Normal strategy: match sampler through local speakers with acoustic sound of piano, add a balanced mix if sampler and live pno through PA. If PA speakers are hanging high, we should have centers on the floor).

Monitor for soloist and conductor.

Video:

• 2 signals from laptops on stage:

• 1 going to a large projector for the big (the bigger the better!) screen behind and above the orchestra.

• 1 going to a small projector for the “custom screen” in front of the piano. This projector will in most cases have to stand in the audience space (short-throw lense) but can in some cases also be projected with a “tele” lense from behind/above the audience.

Custom screen:

Custom screen of wood, maybe thick cardboard could work too, cut after mask, painted with a projection friendly white (matte). 

Orchestra needs stand lamps. Extra light/profiles for pianist and conductor (pianist and pno need to be lit without spilling light on the custom screen). All lights including stand lamps need to be black-out-able on cue from conductor.

Here also a number of photographs taken at a recent performance in Luxembourg, in which the placement of the keyboard on top of the grand piano; a possible computer set-up; the video screen, loudspeaker, and microphone placements; as well as the percussion set-ups can be seen.

The composer will bring the two laptops (which have the necessary software installed) and soundcards with him.
