www.smartelectronix.com/~koen General project info Name KTGranulator Version 1.0 Type VST effect plugin with custom editor (delay line granulator) Author Koen Tanghe Credits This plugin was made as an exploration in building VST plugins and using the VSTGUI library. It was inspired by the great DLGranulator effect in Ross Bencina's AudioMulch. Description Processing Incoming (mono) sound is fed into a delay line from which small pieces of various durations and at different moments in the past are selected. Each of these pieces is then amplified, transposed and enveloped to form a "grain". Each grain is also randomly panned and the whole mix is sent out to a stereo output stream. Feedback of the grain output back into the delay line is also provided. Freezing the delay line is possible as well, and has the effect that new input samples are ignored and grains are generated only from the sound samples that are currently stored in the delay line. Input • audio: mono • MIDI: for parameter control Output • audio: stereo • MIDI: none Parameters • In gain Gain for incoming signal (in dB) • Feedback Feedback factor (0 is no feedback, 1 would be full feedback) • Mix Mixing factor between original and granulated signal (0 is dry, 1 is wet) • IOT Inter Onset Time: time between grain starts (in s) • Dur. Grain duration (in s) • Ampl. Grain amplitude (1 means full original amplitude) • Pan Stereo panning (0 is left, 1 is right) • Delay Delay time: determines start of grain position (in s) • Pitch Transposition (in semitones) • Shape Grain shape factor (0 means triangle, 1 means rectangle) • Skew Skew factor (0 means no attack/full release, 1 is the other way around) • Freeze Delay line freezing status • Max. grains Maximum number of grains to use • Steal Grain stealing (number of active grains is shown at the right) • MIDI MIDI learn (left mouse button) or reset (right mouse button) Tweaking • Most sliders are grouped in pairs: the left one specifies the minimum, the right one the maximum. • For each grain, a value for each parameter is taken randomly between the minimum and maximum. • The lock buttons "lock" the minimum and maximum so that when you change one, the other changes as well. • As usual, Control+clicking sets the parameter to the default value (for the sliders: if allowed by the lock constraints) and Shift+adjusting uses smaller steps for changing the parameters. • The MIDI button has three states: off, learn (shows an "L") or reset (shows an "R"). • All other controls are just standard knobs, buttons or sliders. You know how to tweak these ;-) Using MIDI input for parameter control • All parameters can be controlled using MIDI messages (control change, pitch bend, or note ranges). • The channel on which the message is received is taken into account (so, a CC#74 on channel 1 is not the same as a CC#74 on channel 2). • A MIDI message c…
