Sample Alchemy filters in Logic Pro for iPad
In a Sample Alchemy, the filter module modifies the harmonic content of the sound being produced. It can shape the tonal characteristics of the sound by removing or reducing certain frequencies while allowing other frequencies to pass through.
Sample Alchemy provides an extensive range of filter types, including lowpass, highpass, comb, downsampler, and FM filters. Each filter type has unique sonic characteristics and responds differently to incoming signals.
The filters in Sample Alchemy can also be modulated by an envelope, an LFO (low frequency oscillator), or other modulation sources, which allows them to be controlled over time to create dynamic and evolving sounds. Modulation can be assigned in the Mod Matrix. See Sample Alchemy Mod Matrix.
If you’re new to synthesizers and the concepts behind components such as filters, LFOs, and envelopes, see Intro to synthesizers.
Sample Alchemy filter types in Logic Pro for iPad
This flexible collection of filters allows you to subtly or dramatically sculpt the tone of your instruments:
Lowpass (LP): This filter type passes the portion of a signal below a specified cutoff frequency and rolls off the portion above that frequency. See Sample Alchemy lowpass, bandpass, and highpass filters in Logic Pro for iPad.
Bandpass (BP): This filter type passes a certain band of frequencies and rolls off frequencies on either side of the band. See Sample Alchemy lowpass, bandpass, and highpass filters in Logic Pro for iPad.
Highpass (HP): This filter type passes the portion of a signal above a specified cutoff frequency and rolls off the portion below that frequency. See Sample Alchemy lowpass, bandpass, and highpass filters in Logic Pro for iPad.
Comb PM: This filter mixes the original signal with one or more copies of the signal, which are delayed by a very short time interval. See Sample Alchemy Comb PM filter.
Downsampler: This filter creates a lo-fi digital effect (similar to a bitcrusher). See Sample Alchemy downsampler filter.
FM: This filter uses a modulator oscillator and a sine wave carrier oscillator. The modulator oscillator modulates the frequency of the waveform generated by the carrier oscillator within the audio range, thus producing new harmonics. See Sample Alchemy FM filter.
