SINE/NOISE GEN
Sine/Noise Gen is a utility algorithm, but when used with a real time modulator/controller, can
provide some interesting musical effects. Filters are provided for the noise, but no filters are
provided for the sinusoid.
01 — Mix
02 — Volume
See the descriptions under the Mix and Volume Parameters, in the beginning of this section. We
recommend lower Mix settings.
03 — Sine Frequency Range: 0 to 9999 Hz
This parameter controls the sine wave frequency.
04 — Sine/Noise Gen BalanceRange: 00 to 99
Controls the mix between the sine wave and white noise. A setting of 00 would yield all sine
wave; a setting of 99 would yield all white noise.
05 — Noise Filter Low Pass Fc Range: 100 Hz to 16 KHz
Cuts out the high frequencies and can be used to create pink noise.
06 — Bass Fc Range: 0 to 1000 Hz
Selects the cutoff frequency of the low shelving filter applied to the noise.
07 — Bass EQ Gain Range: -48 to +48 dB
Sets the amount of boost or cut applied to the low shelving filter applied to the noise.
08 — Treble Fc Range: 01 KHz to 16 KHz
Selects the cutoff of the upper frequency band high shelving filter applied to the noise.
09 — Treble EQ Gain Range: -48 to +24 dB
Sets the amount of boost or cut applied to the high shelving filter applied to the noise.
10 — EQ Input Level Trim Range: -24 to +00 dB
Adjusts the input volume before the EQs to eliminate the possibility of clipping boosted signals.
