"The FlangerHand plug-in is based on the idea of early flanging effect
realised on a setup of up to 4 tape machines (1 source, 3 recorders) in the 60's.
The playback-head output from two recorders was mixed together onto a third recorder.
The "flange" effect originated when an engineer would literally put a finger on the flange, or rim of one of the tape reels so that the machine was slowed down, slipping out of sync by tiny degrees
A listener would hear a "drainpipe" sweeping effect as shifting sum-and-difference harmonics were created. When the operator removed his finger the tape sped up again, making the effect sweep back in the other direction. This is where the FlangerHand takes the flanging back in the days of tape recorders and enhances it with new fresh features." Semerika
