This is also known as the Artecho or Art-Echo system.  I have only seen
one Artecho roll in the flesh, which is why one client is having me
convert his art case Apollo grand to the Ampico "A" system.

Artecho was manufactured by Amphion, the same folks that made the
Ampico.  Many of the components, especially the stack and the drawer,
are the same as Ampico A.  The mountings for the tracker bar and the
tracking ears are the same as Ampico A, which makes the conversion
seamless.

Close examination of the Artecho drawer shows that it is a Ampico A
drawer that has been modified at the factory.  The only difficulty
I see is that fitting the intensity units between the posts underneath
the piano will be somewhat of a challenge.

Artecho scale:

1. Bass intensity 1
2. Bass intensity 2
3. Bass intensity 3
4. Sustain Pedal
5. Cancel Bass intensities
6. Bass Diminuendo
7. Bass Crescendo
8. Bass Hammer Rail Up
9-91. 83 playing notes B-A
92. Short perf. Hammer rails down
    Long   "    Rewind
93. Bass Hammer Rail Up
94. Pianissimo
95. Treble Cres.
96. Treble Dim.
97. Cancel Treble intensities
98. Treble intensity 3
99. Treble intensity 2
100. Treble intensity 1

By the way, I have saved the tracker bar and expression units if anyone
needs them.
