Die beste Rotary Speaker Simulation
Der neue Ventilator II ist die neue, verbesserte Version des erfolgreichen Ventilator. Gegenüber dem Vorgängermodell besitzt er einen zusätzlichen, dritten Knopf mit Rotor Stop Funktion sowie Stereoeingänge, welche die Anbindung an Stereokeyboards erleichtern. Des Weiteren haben die 5 Justierknöpfe jetzt eine Doppelfunktion. Es lassen sich dadurch weitere Klangparameter wie Fast/Slow Speed, Accelleration Time, Main Level etc. einstellen.
KNOB 1 -
FAST SPEED (primary function) This is adjustable from -5 to +5. This parameter controls the speed of the virtual upper and lower rotors when on fast speed (known in Hammond parlance as tremolo).
KNOB 1 – SLOW SPEED (secondary function) Adjustable from -5 to +5 as well. This parameter controls the speed of the virtual upper and lower rotors when on slow speed (known in Hammond parlance as chorale).
KNOB 2 – BALANCE (primary function) Adjustable between -5 and +5. The Ventilator II, like its predecessor, splits the input signal at 800Hz (the same frequency as the crossover in the Leslie 122) and processes the resulting two signals independently. The BALANCE control allows the user to determine the mix between the virtual upper rotor and the virtual lower rotor. At 12 o’clock, the mix is equal. Turn the knob to the left and you get less upper rotor (less highs). Turn the knob to the right and you get less lower rotor (less lows).
KNOB 2 – ACCELERATION (secondary function) This controls the amount of time it takes the virtual rotors to accelerate from stop or slow to fast speed. Between 9 o’clock and 3 o’clock the knob controls both rotors equally. Turn it to the left and the acceleration time is shortened. Turn it to the right and it is lengthened. Below 9 o’clock, only the bass rotor acceleration speeds up. Above 3 o’clock, only the upper rotor acceleration slows down. This gives the user a wide range of possibilities not available on a standard Leslie without modification.
KNOB 3 – DRIVE (primary function) This adjusts the amount of overdrive added to the signal. The overdrive is one of my favorite aspects of the original Ventilator. It sounds authentic to a real Leslie 122 pushed into saturation. The Ventilator II overdrive is just as thick and warm as the original.
KNOB 3 – MODE (secondary function) The original Ventilator had two modes, GIT and KEY, selectable via a push switch on the back. The Ventilator II has three modes selectable via knob 3. Mode 1, with the knob at 7 o’clock (all the way counter-clockwise), is GIT1 which represents the guitar mode on the original Ventilator. This mode disables the speaker cabinet emulation and is useful for guitarists who want to maintain the sound of their own guitar amp / speaker combination while still enjoying the rotor simulation from the Ventilator. Mode 2, with the knob at 12 o’clock (middle), is GIT2 from the Mini Vent. This is a more distant, mellower sound and like GIT1 disables the cabinet emulation. Mode 3, with the knob at 5 o’clock (all the way clockwise) is the KEY mode for keyboardists as on the original Ventilator and includes the cabinet simulation.
KNOB 4 – MIX/DIST LO (primary function) This controls the mix of the lower rotor in the signal as well as the distance of the virtual mic from the rotor. The first half of the travel (from all the way counter-clockwise to center) determines the mix. At 7 o’clock (all the way counter-clockwise) there is no lower rotor simulation in the mix. Note this does not remove the bass content from the signal; it simply removes the rotary effect. You can use this to emulate the classic “Memphis style” Leslie sound. The “Memphis style” on a real Leslie is achieved by unplugging the motors on the lower rotor, so that only the upper rotor spins. From center to 5 o’clock (all the way clockwise), the knob adjusts the distance of the virtual mic from the lower rotor. This is handy for decreasing the amount of AM (amplitude modulation) in the signal. Pulling the mic further back decreases the “wub wub wub” effect that can be distracting, especially when you’re playing left hand and/or pedal bass. It might be cool for organ dubstep, though.
KNOB 4 – REMOTE (secondary function) This parameter changes the function of the REMOTE input jack on the back depending on the position of the knob. With the knob at 7 o’clock (all the way counter-clockwise) the REMOTE jack is off. With the knob at 10 o’clock, the MIX/DIST LO and MIX/DIST HI knobs can be externally controlled via an expression pedal like the Yamaha FC7. The range is from zero to the value set by the two knobs. With the knob at 12 o’clock, the SPEED is continuously controllable via an expression pedal like the Yamaha FC7. The range is from the value of the SLOW SPEED as set by the knob (pedal minimum) to the FAST SPEED as set by the knob (pedal maximum). This is a very neat feature. With the knob at 3 o’clock, stop/slow/fast speeds are switched (non-continuously) by external latching switches like the Hammond CU-1 halfmoon and original Ventilator remote. With the knob at 5 o’clock (all the way clockwise) the stop/slow/fast speeds are switched (non-continuously) by unlatched switches such as sustain pedals and the Ventilator II remote.
KNOB 5 – MIX DIST/HI (primary function) As with knob 4, this controls the mix of the upper rotor in the signal as well as the distance of the virtual mics from the rotor. The first half of the travel (from all the way counter-clockwise to center) determines the mix. At 7 o’clock (all the way counter-clockwise) there is no upper rotor simulation in the mix. Like knob 4, this doesn’t remove high-frequency content from the signal but rather the rotary simulation of the high frequencies. From center to 5 o’clock (all the way clockwise), the knob adjusts the distance of the virtual mics from the upper rotor.
KNOB 5 – LEVEL (secondary function) This adjusts the overall output level. The default is the middle position. As well as the knobs there are three silent foot switches on the face. From left to right they are BYPASS, STOP, and SLOW/FAST. BYPASS engages a true analog relay-controlled bypass of the Ventilator II’s circuitry. The STOP switch stops the virtual rotors from spinning and positions them towards the virtual mics every time. SLOW/FAST switches between the slow rotor speed and the fast rotor speed
Pressing BYPASS and SLOW/FAST together put the Ventilator II’s knobs into 2nd FUNCTION mode as indicated by the LO/HI LEDs blinking twice per second. Pressing BYPASS and SLOW/FAST again exits from 2nd FUNCTION mode.
