Article from Polyphony, April/May 1978


AR: Attack: Expand on, 0% Release: 15%
Glide: medium amount
Oscillators: 20% pulse; tuned in mid range so that they are in unison when second "C" on keyboard is played.

The playing here should be very legato. Another "drone" oscillator would probably help, perhaps a fifth up.

This patch produces an imitation of the popular Mu-tron Bi-Phase.

The input is preferably "Thick" — multi-track brass or strings, although funky bass lines work well, too.

Both filters - Q to suit.
Initial frequency of Low Pass Must be slightly lower than that of high Pass but within one octave.
Set Bias to prevent Lock-up and/or Set sweep range.
LEO Frequency and Level to suit.

AR: both outputs 5v.
Bias: -2.5v.

Any patch into the balanced modulator can be used. AR settings are variable. A setting which produces this output: [simple ADSR envelope response] produces this envelope: [extra attack and release stage envelope].

This patch gives the distinctive "Eventide" cancellation used by Isao Tomita. It works best on "Thick" sounds - multi-track Brass, String Ensembles, or noise.

Control Settings:
Phlanger #1:
Speed: Minimum
Span: Minimum
Center: Maximum
Accent: To suit - minimum best.
Mix: 100% Delayed only

Phlanger #2
Accent: To suit - minimum best
Mix: 100% Delayed only
Speed/Span/Center: Adjust the desired effect as though using a single phlanger

Inverter: use 0db input
Mixer: adjust input levels for best cancellation
Pan to suit, but Both inputs MUST be the same


- 12 stage recirculation
- Alternate high and low stage settings, no glide
- 50% step trig, out

VCO - Pulse out 50% duty

AR - Attack 0%, Decay 0%, Expand off, 5vp-p
LFO - 1Hz, 5vp-p

Submitted by: David Setser, Morehead, KY


Keyboard: High range - no glide
VCO 1 & 2: Tuned almost in unison (about 30Hz beat)
LFO: 5Hz/VCF: Q maximum
AR: Attack minimum/Release 1/3, expand off

While somewhat more involved than Gary Bannister's patch in Polyphony 1/76, this patch has a nice metallic sound which I like and sounds good even down at the low end of the keyboard.
