A-138f Dual Three Way Crossfader
Doepfer A-138f - Dual Three-Way Crossfader
The Doepfer A-138f contains two identical crossfaders with three inputs and one output each. Three different signals are connected to the inputs A, B and C. In the counter clockwise position of the corresponding control only signal A appears at the outputs. Between counter clockwise and centre position a mix of the signals A and B appears at the output. In the centre position on signal B appears at the output. Between the centre and clockwise position a mix of signals B and C appears at the output. In the clockwise position only signal C appears at the output.
• Crossfading of VCO waveforms (eg. saw, square or triangle)
• Crossfading of VCF outputs of multimode filters (eg. lowpass, notch, highpass or bandpass)
• Crossfading of control voltage signals (eg. envelope, LFO or random)
