    2 Connections 18 Connecting audio The Philt re will work in many different applications, whether y ou are connecting an inst rument directly into it, or connecting it through a mixing console. But since the Philt re is a stereo effect unit, it’s important to know whether the source will be stereo or mono. Mono In, Mono o r Stereo Ou t If you’re ...

    Connections 2 19 Connecting to the Channel Inserts o f a mixing console: Most recording consoles ha ve a jack near the mic and line inputs labeled "Insert". This is typically a TRS jack with the send and retu rn on the same jack. To use the Philt re as a channel insert, y ou will need an insert cable (not included). This cable splits the ...

    2 Connections 20 Connecting to the Main Ou tputs o f a mixing console: In addition to channel inserts, most mixing consoles have main insert jacks near the main outputs. You can use insert cables to connect the Philt re to the main L/R bus the same way y ou connect it to a pair of channels. Simply connect one insert cable to the left main insert of ...

  • Alesis ModFX - page 28

    3 Using the Philtre 26 Filter curves, orde rs, and slopes When you look at a graphic display of their frequency response, e very filter has a slope —gentle or steep, like the slope of a hill. The passband —the frequency range that the filter lets through—looks like a flat plateau. The frequency at the edge of that plateau, just as the respons ...

    Using the Philtre 3 27 What is Tempo Sync ? Three of the five mod sou rces in the Philtre have a repeating cycle over time (Triangle, Sample/Hold, and Pattern ). Sometimes, you’ll want the rate of that cycle to match the beat of your music instead of being random. For example, y ou c an set the rate so that the sweep of the filter completes each ...

  • Alesis ModFX - page 30

    3 Using the Philtre 28 Description of Controls Rate The [RA TE] knob changes the filter modulation speed. When the mod sou rce is set to ENVELOPE it affects the attack and release time of the envelope, in TRIGGERED mode it affects the release time. In all other modes it affects the LFO (lo w frequency oscillator) speed. In normal modulation modes ( ...

  • Alesis ModFX - page 31

    Using the Philtre 3 29 Depth The [DEPTH] knob controls how much modulation will be applied to the filter frequency. Tu rn the knob clockwise for a deeper effect. Tu rning [DEPTH] all the way counter-clockwise tu rns modulation off completely, leaving the filter fixed at the [PHREEQ] position. Depth interacts with the [PHREEQ] cont rol (see next pag ...

  • Alesis ModFX - page 32

    3 Using the Philtre 30 Re gen The [REGEN] knob does several different things depending on the filter type. But in each filter it increases the amount of filter resonance (how much gain is added near the corner frequency), which creates a peak in the response as shown belo w: [REGEN] at minimum [REGEN] at maximum • To increase resonance, tu rn [RE ...

  • Alesis ModFX - page 33

    Using the Philtre 3 31 In BAND STOP mode, with [REGEN] set to minimum, the band that is being attenuated is relatively wide. As you increase the [REGEN] setting, the stop band gets nar ro wer. At th e maximum setting, with the addition of filter resonance, the Band Pass filter essentially becomes a narrow notch filter with a high “Q”, like a pa ...

  • Alesis ModFX - page 34

    3 Using the Philtre 32 Modulation Select Switch The up/do wn rocker switch on the right side of the unit selects the modulation source for the Philt re. The LEDs next to the switch light up to indicate the cu rrent mode. There are five kinds of modulation available, explained below. The rocker switch also selects TEMPO SYNC mode, as explained earli ...

  • Alesis ModFX - page 35

    Using the Philtre 3 33 Trigge red This is one of the most useful effects in the Philt re for lead players. Instead of using a repeating wave or LFO, the filter is kept lo w (at the point set by the [PHREEQ] control) until there’s an accent in the incoming signal. An accent (a sudden increase above the a vera ge input audio level) is called a trig ...

  • Alesis ModFX - page 36

    3 Using the Philtre 34 Envelope Like Trig ger, Envelope modulation takes its cue from the input signal instead of using a periodic wa ve. In Envelope mode, the filter frequency follows the average amplitude envelope of the incoming signal—the louder you play, the higher the filter frequency will mo ve. Envelope is used in “auto-wah” effects, ...

  • Alesis ModFX - page 37

    Using the Philtre 3 35 Patte rn This mode randomly generates a 16-step sequence to modulate the filter and repeats it o ver and over. Pattern mode makes the filter jump quickly from step to step, sometimes with a glide between steps. It sounds somewhat like “sample and hold” modulation, e xcept that the pattern will step through the same 16 ste ...

  • Alesis ModFX - page 38

    3 Using the Philtre 36 TYPE Rocke r Switch The up/do wn rocker switch on the left side of the unit selects the type of filter. The LEDs next to the switch light up to indicate the cu r rent type. There are fou r types available, explained below. Low Pass Perhaps the most-popular type of filter effect, the Lo w Pass filter has a 2-pole, 12 dB per oc ...

  • Alesis ModFX - page 39

    Using the Philtre 3 37 Band Pass The Band Pass filter has two 2-pole, 12 dB per octave slopes: one rolling off high frequencies abo ve the center, and another rolling off lo w frequencies below the center. It’s like a high pass filter combined with a low pass filter, with the corners set to let the midrange through. The distance between the two s ...

  • Alesis ModFX - page 40

    3 Using the Philtre 38 Steep For a more dramatic filter effect, press the [STEEP] button. [STEEP] quadruples the number of filter poles being used. This means that more frequencies are rejected, and if [REGEN] is tu rned up, the resonance effect is more pronounced. Here is a chart of the effect of the [STEEP] button: No rmal slope Steep slope 2 p o ...

  • Alesis ModFX - page 41

    Using the Philtre 3 39 Tap Tempo This button affects the speed of the effect whenever the [MODULATION] switch is set to a TEMPO SYNC mode. At any time y ou can tap this button along with the music to set a new tempo. The Tap Tempo light will flash at the cu r rent tempo. Tap Tempo technique For a reliable tempo setting, make se veral taps in a row ...

  • Alesis ModFX - page 42

    3 Using the Philtre 40 By pass This button sends the signal directly from the input to the output without any effect. Press [BYPASS] to check the sound of the source without any effect from the Philt re. When the red BYPASS LED is lit, phasing is tu rned off. The Bypass function can also by activated by the foot switch. Since the Philt re is a digi ...
