Conceptually, I wanted to simultaneously hear all of the installed Terrain Instruments at any given time. I accomplished isolated analog recordings. The images on these pages are but specifics as well and document portions of the original Permanent Forest Terrain Instrument's whole. Not being able to do this in realtime was disappointing; however, using an NEA Development Grant funded Nagra 4.2 reel-to-reel recorder, I accomplished many full track, 15 I.P.S. analog recordings of all Terrain Instruments. Video recordings by others and myself were also completed. On this page was the site from which satellite performances originated- featuring the oldest "major" Birch tree. As realtime on-call resources or remotely controlled rain drops triggering on/offs of any TI, all were capable of being telephone-controlled via keypad, where specific Instruments could be called up and/or activated throughout the 2-way satellite interactivities. Some of which were satellite relayed through equalized 600 Ohm telephone wires. Or. Uplinked from KSJN for Westar 5 downlinking. The modulated laser sound inputs were translated by a Radiometer for mixed uses.
Above and below V.1 is shown in two connected but different locales. Hefty turnbuckles hold the pair via a U-shaped steel rod: below image- windribbon is paired with a 9 gauge galvanized steel strand... windribbon is at back back with e 9 gauge strand faceing outward...each monitored wind and torsional tree movements...
earlier view of Major Birch
Coming off a pair of trunbuckles as seen from below... all strands are anchored to another distant birch tree. For the duration of its sounding life ('75-'86), this tree was referred to a Major Birch. It served as the main anchor for combinations of multiple strand configurations and served also as the anchoring live flagship-soundsource during realtime and interactive Westar satellite (and for teleconstruct spaceworks) projects. The tree succumbed to bronze birch borer disease in 1988 several years after a nearby tree fell and brought down this v.1. The vertical aluminum tube in the 2nd top image was (part of the terrestrial whistler(s) and was physically attached to the 9 gauge strand which parallels the windribbon.. (Producing combind hums and whistles from the same wind gusts).
DETAIl: pair of turnbuckles grasped and held the windribbon taut. Tied down and wrapped outward onto the first inches(this shared the tension at the crutial point) also you can see an additional 9 gauge steel strand which ran parallel.

VIEW of surviving base of the wind-toppled Major Birch showing the now disconnected and severed fat blue cables shown in both pictures carried the amped and line-level output into a nearby basement soundroom. Sensor inputs are the three RCA females dangling from the bottom (with one still attached). A nearby solar panel supplied the DC for the preamp and amp outs.
An FM transmitter (in this photo of a VHS box is tie-wrapped to tertiary limb) and allowed for nearby FM radios to overhear sound collections from this listeningsource. FM radios on nearby London Road were able to tune into the Major birch throughout its electronic activation.

Standing w/earphones near the Whistlers pine sounding block I could hear the douglas fir tree's wind-stirred moans from a different amplified line allthewhile moving-and-touching my stethoscopic-like sensor among six isolated copper and aluminum tubes. I could also easily hear the hardware resonating (whistling) during gusts.

Positioned beneath tree canopies and during prolonged, preferrably steady and slow periods of raining, an attempt to manipulate isolated drops was attempted. A pair of worm gears controlled within wooden blocks could corkscrew up or down as a result of solenoid wratcheting: ((data recorder-move pause measure)) This up/down flexibility would position a galvanized strand on either end to be lower or higher. The wratcheting was electro mechanically triggered by raindrop variations and other sound sources in the Terrain Instrument complex. Object to monitor actual raindrop raindrop movements traversing when either lowered or raised much as a finger traces a bow string to change pitch. Conceptually rain collisions would electrically control a corkscrew electro-mechanical bolt- in either direction- to raise or lower a sounding block.Purposely the equivalent to sliding a finger- to affect a sounding result on a bow string.
