GRAIN SAMPLE MANIPULATOR229
The Modulation Bus section
The Modulation Bus section is used for routing a modulation Source to one or two modulation Destinations each.
This creates a very flexible routing system that complements the pre-wired routing in Grain.
The Modulation Bus section in Grain is derived from the one in the Reason Thor Polysonic Synthesizer device, so if
you are familiar with Thor, you will quickly find your way around in Grain’s modulation bus.
There are eight “Source –> Destination 1 –> Destination 2 –> Scale” busses, of which the first four have pre-as-
signed sources. However, these four pre-assigned sources can be easily changed if you like.
A Source parameter can modulate two different Destination parameters per bus (with variable Amount settings).
Each bus also has a Scale parameter that affects the relative modulation Amount for both Destinations.
q Note that it is possible to assign the same source parameter as Source in several busses. This allows you to
control more than two Destination parameters from the same Source.
1. Select the desired Source parameter by clicking in the corresponding Source box and selecting from the list.
The following parameters can be used as modulation Sources:

Description
Velocity This applies modulation according to the Keyboard Velocity values (how hard or soft you strike the MIDI
keyboard keys).
LFOs (LFO 1, LFO 2 and LFO 3) This allows you to modulate parameters from LFO 1, LFO 2 and LFO 3 respectively.
Envelopes (Amp Envelope, Envelope 1,
Envelope 2, Envelope 3, Envelope 4,
Envelope 3 * Envelope 4, Envelope 3 *
LFO 3)
This allows you to modulate parameters from any of the Envelopes.
As a special feature you can also modulate parameters from the multiplied signal of Envelope 3 and
Envelope 4, as well as from the multiplied signal of Envelope 3 and LFO 3.
Mod Wheel This allows you to modulate parameters from the Mod Wheel.
MW Latched This allows you to modulate parameters based on the current Mod Wheel value at a given Note On.
Pitch Wheel This allows you to modulate parameters from the Pitch Bend control.
Breath This allows you to modulate parameters from the Breath performance controller
Expression This allows you to modulate parameters from the Expression performance controller
Aftertouch This allows you to modulate parameters from Keyboard Aftertouch (channel aftertouch)
Sustain This allows you to modulate parameters from a connected sustain pedal. Note that continuous sustain
data (0-127) is supported - not just on/off.
Key This is keyboard tracking. If a positive Amount value is used and the destination is filter frequency, the
filter frequency will track the keyboard, i.e. increase with higher notes.
Random This sends out a random value each time a new note is played.
Key In Octave This allows you to modulate parameters based on 12 separate note values (within each octave).
Noise This allows you to modulate parameters from white noise.
Polyphony This allows you to modulate parameters based on the number of playing voices at a given time.
Last Velocity This applies modulation according to the latest Keyboard Velocity value (how hard or soft you hit the
latest MIDI keyboard key).
Sample Pitch Curve As soon as you load a sample in Grain the pitches throughout the entire sample is automatically analyzed
and saved as a “Pitch Curve”. This allows you to modulate parameters based on the analyzed pitch value
at the Position marker’s current position in the original sample.
