[. . . ] The LFOs in each Part are independent of each other, so they can be running at different speeds. When a key is pressed, that voice's LFO may be at the top of its cycle, at the bottom, or anywhere else in the cycle when it begins to affect the voice. Some LFOs may be going in one direction (rising) while others are going in the opposite direction (falling). When the first key is pressed, the LFO's cycle resets to the beginning. When a second key is pressed, the LFO will reset its cycle to the beginning and start over. Each voice has its own LFO that resets when the voice is triggered. Remember that it is possible to have the LFOs set independently, so that one LFO's Reset parameter may be set to poly, for example, while the other's is set to keymono. poly key-mono key-poly 45 5 Program Parameters LFO [edit]: M1 to LFOx Page: Soft Button: Range: Default: 2 1 0-100% 0% In order to use an LFO as a modulation source, you must use the mod matrix to designate a parameter as its destination. For more information, see Chapter 6. There are several ways to use an LFO, but the two main ways are as an expressive modulation source tied to one of the wheels, or as a constant modulation source for some aspect of the sound. This parameter determines whether the LFO will be used as one or the other, or as a blend of both. If you want the LFO only available from (m1), set this parameter to 100%. If you want the LFO to provide some amount of constant modulation regardless of the position of (m1), set this parameter to something less than 100%. When this parameter is set to zero, the LFO will always be full-strength. LFO: the [1] button This button selects LFO 1's parameters for editing. It also immediately takes you to LFO Edit page 1 with the LFO Rate parameter selected. For a description of the various LFO-related parameters, see the LFO [edit] sections on this and the previous page. LFO: the [2] button This button selects LFO 2's parameters for editing. It also immediately takes you to LFO Edit page 1 with the LFO Rate parameter selected. For a description of the various LFO-related parameters, see the LFO [edit] sections on this and the previous page. LFO: the [s&h] button This button selects the Sample & Hold's parameters for editing. It also immediately takes you to S&H Edit page 1 with the S&H Rate parameter selected. The Sample & Hold generator and its parameters are described in the following section. 46 Program Parameters Sample & Hold (S&H) Most of the Sample & Hold's parameters are identical to those of the LFOs discussed on pages 45-46, so we will only list them and refer you to those pages. There are some important distinctions, though, and we will point those out. What does Sample & Hold mean? 5 S&H [edit]: Rate Page: Soft Button: Range: Default: 1 1 0. 010 ­ 1000 hz or x 16 ­ x 1/16 0. 100 hz Sample & Hold is a term that originated in the early days of analog modular synthesizers. It describes the process by which a reading, or "Sample, " is taken at regular intervals of a particular input source, such as an LFO. That Sample becomes a value that is fed to a destination, such as filter frequency. The destination parameter is held at this value until the "Hold" period has expired, at which time another Sample of the input source is taken and fed to the destination, and so on. This is where the initial rate for the Sample & Hold is set. If the [s&h] button is selected, you can edit the rate of the Sample & Hold by turning the rate knob.

Spray the cleanser onto a cloth, then use the cloth to clean the unit. NEVER spray any cleaner directly onto the Ion -- this can destroy the lubricants used in the switches and controls! 102 Specifications Sound Engine Sound Generation: Polyphonic Voices: Alesis proprietary DSP Analog Modeling 8, each with 3 oscillators, 2 multi-mode filters, 3 envelope generators, 2 LFOs, programmable effects send and modulation matrix. 512 Preset Programs, 32 Multi-timbral Setups, all user-rewritable 4 Drive Effects (1 each per Part) plus Master Effects (Shared) Program Memory: Effects: Audio Input Input Connectors: Maximum Input Level: Input Impedance: 2 Balanced 1/4" TRS jacks +5. 2dBu (1. 41VRMS) = -0dBFS 10k Audio Output Output Connectors: Maximum Output Level: Output Impedance: 4 Impedance-Balanced 1/4" TRS jacks, ¼" TRS Headphone Jack +18dBu (6. 17 VRMS) = -0dBFS 1k All measurements done over a 20Hz ­ 20kHz range with a 1kHz sine wave at -1dBFS input.
