The “heartbeat” is Fender Jazz bass connected to Mbox2 via a Line 6 Bass Pod XT Live using Crytocercus setting. The distorted wobbly bass was same using Tetracycline setting. Both were played straight through the chord changes, then looped. The guitar part is a Gibson SG tuned to open E5 and played lying in lap with a National Rail Bar and Jim Dunlap thin pick and connected via a Line 6 Pod XT Live through the Mbox2 into an iMac. The keyboards are software settings in Garage Band. One is Cathedral Pipe Organ. The other is a Synthesizer setting… which is not precisely the sound hoped for… but….
Key of E minor. Used Power Chords on guitars and synth. Minor chords on pipe organ. Straight time, played straight.
Anticipate vocal will be added tomorrow….
Then… it may get a bit spooky….
