 Their sound is largely dependent upon older synthesiser technology, notably instruments such as the Moog 3C which they combine with more recent digital technology.The basic technological philosophy of Redshift is to use analogue synthesis where possible, augmented where necessary by digitally sampled versions of hard-to-maintain analogue instruments such as the Mellotron.Redshift use analogue instruments manufactured by Moog, Yamaha, Oberheim, Korg, Roland, PPG, Analogue Systems, Doepfer, Modcan, Solina, and Fender Rhodes.
