"Manufacturer Description:
The MF-103 12-stage phaser is a direct descendant of the original Moog modular synthesizers, yet can be used with any instrument level to line level signal. It contains two compete modular functions: a 6 or 12-stage phaser with resonance control, and wide range LFO with amount control.

The 12-Stage Phaser's control parameters are Sweep frequency, Resonance, LFO Rate and LFO Amount. All of these parameters can be controlled by the great feeling knobs that beg to be tweaked as well as expression pedals or external control voltages. Panel switches select ranrge of LFO Rate and 6 or 12 stage phasing. 1/4" jacks are provided for audio input and outputs, pedal/control inputs, LFO out and auxiliary sweep input for bi-phase effects. The heavy-duty yet smooth-acting bypass switch allows tabletop or floor use.

A phaser is a type of comb filter, so called because its frequency response has several dips and peaks, like the teeth of a comb. As the phaser response sweeps back and forth across the frequency spectrum, the harmonics of the audio input signal are alternately increased and decreased. This produces the classic phaser "whooshing" sound.

Phasing is one of the best ways to impart motion to a track and to make sounds come alive. With the MF-103 Phaser you can get swirling, shimmering, vibrating effects; fill up a whole stage from one sound source; even create brand new sonic textures.

The MF-103 produces two comb-filter responses. They are called 6-Stage and 12-Stage, because of the number of phase-shifting circuits that are used internally. The 6-Stage mode has three dips in its frequency response, while the 12-Stage mode has six dips. These two modes have distinctly different sound qualities. In addition, the MF-103 features a variable feedback circuit which increases the resonance, or depth of the phaser sound.

Yamaha TX7 :: The Classic DX7 FM Synth in a Desktop Module

via this auction
"The TX7 was sold in the 80's as an expander, to double the memory of your DX7 synth, but instead of merely being a storage device the TX7 is actually a complete, programmable [via external editors only], working DX7 synth in a stackable module which can be played via midi from ANY keyboard or sequencer / DAW.

The one compromise is that as the front panel of this unit is quite basic compared to the full keyoard version of the DX7, so you will need a PC or MAC DX7 editor/Librarian application to program the unit, or if you want to take advantage of the 1000s of free DX7 sounds available online, but I will include a CD containing loads of patches and editor/librarians to get you going.

This page is also very useful"
