Reason+ Rack Extensions Operation Manual
When you play a note on your keyboard, the envelope is triggered. This means it starts rising from zero to the value set with the “Volume” knob How long this should take, depends on the Attack setting. If the Attack is set to “0”, the Volume level is reached instantly. If the Attack value is raised, it will take longer time before the Volume level is reached.
The Filter Envelope can be used for modulating the Filter cutoff frequency (Freq) over time. You set the modulation amount with the “Amount” knob in the Filter section. It features the standard Attack, Decay, Sustain and Release parameters of an ADSR envelope.
*
Set the time it should take to reach from the set “Freq(uency)” value to the maximum Filter Frequency value.
*
Turn the Velo knob to set the keyboard velocity sensitivity, i.e. how much keyboard velocity should affect the Filter Envelope “Amount” (see below). If the Filter Envelope “Amount” is 0, Velo won't do anything. If the Filter Envelope “Amount” is negative, Velo will cause a deeper filter "dip" with higher velocity.
*
You can turn down Depth and modulate the Manual parameter in the “Modulation Matrix”, for example with an envelope or an LFO for alternative chorus effects.
This allows you to modulate parameters from the “Macro” knobs/handles. If you have named the Macro controls, the source column will show those names.
This affects the sample “Start Pos” parameter of the Sample Engine.
This affects the “LFO 1&2” modulation signal intensities. Use this to control the amount of LFO modulation from some other source (e.g. have the Mod Wheel controlling the amount of vibrato).
