![]() ![]() Try applying an LFO to channel pitch, oscillator amplitude, filter frequency, or filter resonance. In addition to envelopes, you can apply LFO (Low Frequency Oscillators) to any parameter of your patch. You can also link the filter envelope to the amplitude envelope for that oscillator (or anything else), so that you only have to edit one envelope to change both. You can experiment with having your filter decay faster than your envelope, or fade in slower than your envelope, for different effects. You don’t have to start at 20 hz, nor do you have to move to the maximum amount you set in your patch. You can click on a breakpoint in the envelope to see the frequency value at that point. If you set your sustain level lower than maximum, the filter frequency will be lower than 10,000. For example, if your cutoff frequency is specified at 10,000 Hz, then the maximum value for the filter frequency envelope will be 10,000 Hz. Your envelope for filter frequency will be a percentage of whatever value you specify in the patch. Brightness and amplitude usually track together, or in related ways. A good thing to start with for filter frequency is to copy your amplitude envelope and paste in into the filter frequency envelope. For sounds that fade in, or have legato attacks, your sustain level will usually be the same as your ending attack level.Īdd envelopes to control filter cutoff frequency, and maybe resonance. To create the impression of a short, accented attack, you should drop the sustain level -6 to -12 dB below the attack level. You can drag breakpoints to lengthen/shorten attack, initial decay, and release times. When you create a new sound, Absynth provides initial ADSR amplitude envelopes for oscillators A, B, and C (whether your have all three oscillators active or not). If you command-click on the Envelope tab, the envelope window will pop out as a separate window. #Ball state ilocker manualOnce you have experimented with manual changes to filter settings, start adding and editing envelopes. ![]() #Ball state ilocker PatchAny parameter you can change in the patch window can be automated through the use of envelopes, LFOs, and MIDI performance controls.Īdd envelopes and LFO modulations to synthesis parameters Try LPF’s with additional poles.Īlways be listening to the result of these manual controls. That boost can give you a sense of cycling through the partials/overtones, as a partial will jump out when the cutoff frequency sweeps past it. The more resonance you have, the more amplitude boost you get at the cutoff frequency. Now add varying amounts of resonance and do the filter frequency sweep again. Sweep the cutoff frequency up and down to hear how the sound can brighten and darken. Stick to the filters with the pole designations for a more analog style design and sound.Īdjust the filter frequency and resonance controls. More poles (4 and 8) provide a steeper response slope (24 dB and 48 dB per octave, respectively). The default filter is a LPF 2 Pole, which stands for Low Pass Filter with a two sample filter delay, providing for a 12 dB per octave slope after the cutoff frequency. Click on the left-edge title bar to add a filter to the synthesis chain. Try selecting the different elemental waveforms to hear the difference between them.įilters provide a way of boosting and cutting the amplitude of specified frequency ranges, which can alter the timbre of the sound over time. With a rich sound source, you can apply filtering with modulation to get interesting results. In the beginning it will be easier to start with a wave rich in frequency content (anything but a sine, and less likely to be a triangle). The inharmonic waveforms can be of use as well. Let’s start with the Single oscillator type, which has a selectable waveform.įocus on the elemental waveforms (sine, triangle, square, sawtooth, noise) and their filtered variants. #Ball state ilocker generatorAbsynth has a flexible generator that can go from a single oscillator, to modulation, to samples, to live audio input. Typically, these generators take the form of oscillators, and Absynth uses the abbreviation OscA (and OscB, OscC). Start with an interesting sound source generatorĪt the top of any synthesis chain in Absynth (or any other synthesis program) is a sound generator.
