Korg MICRO manual OSC1 SYNTH/VOCODER, Editing example for a vocoder program

1.VOICE — SYNTH/VOCODER

The "1. VOICE" parameters are the same as for a synth program with a "SINGLE/LAYER" setting of Single (➝ p.16).

To use the program as a vocoder program, set "SYNTH/VOCODER" (knob 1) to Vocoder ()).

2.PITCH — SYNTH/VOCODER

The "2. PITCH" parameters are the same as for a synth program (➝ p.17). They specify the pitch of the carrier.

3.OSC1 — SYNTH/VOCODER

Here you can select the waveform of the carrier.

The "3. OSC1" parameters are the same as for a synth program (➝ p.18).

By selecting a different waveform for "WAVE" (knob 1) you can change the depth of the effect. Normally, you will set OSC 1 "WAVE" to be a triangle wave which contains a rich set of overtones, or VOX WAVE which simulates a waveform similar to that produced by human vocal

cords. Alternatively, you can select DWGS (), and use "CONTROL 2" to select waveform number 26 (5th Wave3: a fifth interval), and play a chord to obtain rich sounds.

Editing example for a vocoder program

1Adjust the audio from the mic input.

Turn the EDIT SELECT 1 knob to the AUDIO IN 1 position.

Turn knob 2 ("THRESHOLD"). As you turn the knob toward the right, the sound will be cut more readily. Adjust this so that noise is not obtrusive when you are not speaking into the mic. Then adjust knob 1 ("GATE SENSE") so that the vocoder sound that is output is not cut off in an unnatural way.

Turning knob 4 ("HPF GATE") toward the right will emphasize the consonants (e.g., "s" sounds) of the input voice. (➝ p.33)

2Make filter settings.

Turn the EDIT SELECT 1 knob to the FILTER position.

Turn knob 4 ("EF SENSE") to adjust the sensitivity of the envelope follower. As you turn the knob toward the right, the vocoder output

will rise more smoothly, and the release will become longer.

Turning knob 2 ("CUTOFF") or knob 1 ("FORMANT SHIFT") will vary the cutoff frequency of the band pass filter for the carrier, changing the character of the vocoder output. (➝ p.35)

Turn the EDIT SELECT 2 knob to the CH LEVEL A or CH LEVEL B position. Turn knobs 1–4for CH LEVEL A or CH LEVEL B to adjust the band pass filter output levels for each of the eight channels of the carrier.

Turn the EDIT SELECT 2 knob to the CH PAN A or CH PAN B position. Turn knobs 1–4for CH PAN A or CH PAN B to adjust the band pass filter output pan for each of the eight channels of the carrier.
