On the Modulation Oscillator I want to make a simple tremolo sound. Easy enough. Init patch. Turn up the VCA amount with a sine wave selected, and everything works fine…I get a nice panned tremolo effect. However, when I set the waveform to sawtooth, pulse or square….I hear popping or clicking sounds the most. These waveforms work fine in the modulation oscillator with other elements (PWM, Filter and Pitch), they all sound as they should. What am I doing wrong or how do I smooth out these abrasive and unusable popping transients. I love the ramp tremolo, but these are unusable without having those transients smoothed out a bit. Square is all pops. Would love some guidance or help. Thanks!
btw…I am not using anything as audio rate and do not have KB tracking or reset engaged in MOD OSC section.
I think I can hear what you are saying, but not sure it is subtle at best.
Be sure mod osc is set to zero in the mixer.
I think what you are hearing is speak pop, this is when the speaker goes from 0 energy to max energy. You can hear this clearly by turning off osc 1 in the mixer and turning osc mod up. Be sure to turn osc mod to 0 in the mixer and turn osc 1 back up, once you’ve heard this.
With a wave form with a sharp transition (e.g. non sine) in the mod osc it is sending 0 energy to a speaker, then at a sharp pan transition slams it full energy.
To get rid of clicks, you could use an LFO instead of the mod osc. Create the following in the mod matrix; source LFO1(bi), destination VCA pan at 100%, Func set source to slew say at a value of 3, this will smooth any sharp transitions. Select the more button for LFO 1, and change LFO type to per-voice. Turn the pan spread knob all the way up clockwise.
Yes! That was exactly what I was looking for. I took it a step further and put sync on the LFO…awesome rhythmic pulse. Thank you!
It still kind of stinks you can’t add slew to the waveform in MOD OSC section. No matter, this accomplishes virtually the same thing, just without the “ramp” waveform. We make some tradeoffs
