Hohner Clavinet
Most famous for having been used on Stevie Wonder’s “Superstition”, Rufus and Chaka Khan’s “Tell Me Some-
thing Good”, and on nearly all of Bob Marley’s hits, the Clavinet had originally been conceived by Ernst Zacharias
of Hohner, to be the next stage in the evolution of the clavichord. The electro-mechanical keyboard so well known
for its “funky 70’s sound”, had been intended to play Bach.

for its “funky 70’s sound”, had been intended to play Bach.
The Clavinet’s 60-note keyboard extended from F1 to E6, and its action was light to the touch. Under each key was
a metallic string, which would be pressed down onto an “anvil” when the key was struck. The string would
vibrate as long as it remained in contact with the anvil, and was dampened immediately upon key release. Two
sets of magnetic pick-ups, which resembled the “treble” and “rhythm” pickups on an electric guitar, produced an
electrical signal, which was fed to the output of the instrument.

The Model C, introduced in 1968, and the more popular Model D6, introduced in 1971, were the two most widely
used versions. The D6 featured a series of six rocker switches, which controlled tone and pick-up selection.
Labeled “Brilliant”, “Treble”, “Medium”, and “Soft”, the first four switches were connected to a series of band-pass
filters. The next two switches enabled each of the pick-ups. Both could be selected, with the choice of them being in
or out of phase. The D6 also featured a sliding “mute” lever, which controlled how fast a held note would decay.

Classic Keys features samples of the “treble” pick-up along with a “release thump”, while the PC2 base ROM
already contains samples of the “rhythm” pick-up. Many of the Clavinet programs in Classic Keys were designed
to imitate the D6’s various switch combinations, making use of the PC2’s own MIDI sliders and switches.

ARP Solina String Ensemble
The Solina String Ensemble, built for ARP by the Dutch organ manufacturer, Eminent, was the most well known
string synthesizer of the mid-seventies, amid a field of similar, less successful competitors. Its distinctive string
sound has appeared on a wide variety of recordings, having been used by Herbie Hancock, The Band, Vangelis,
Pink Floyd, Parliament/Funkadelic, New Order, and many other well-known artists. Housed in a sleek wood
enclosure, the Solina was capable of producing haunting, ethereal strings in the upper register, and lush pads in
the lower register.

The String Ensemble was not a true polyphonic synthesizer, and employed a “divide down” single oscillator (com-
mon in electronic organs) to generate a polyphonic saw wave. All of its voices were fed into a single envelope gen-
erator which afforded the user control over attack (labeled Crescendo) and release (labeled Sustain). A button
labeled, Modulation, enabled the famous “Bucket Brigade” chorus circuit, which added to the warm quality of the
Solina’s sound. Many of the String Ensemble programs in Classic Keys use the PC2’s MIDI sliders and switches to
emulate the Solina’s front panel controls.
