automation, which are applied once a new note starts. If you want to achieve continuous
changes as a note plays, you may want to use the Simpler.
Slot 8's parameters also include a Link button, located in the lower left corner, which links
slot 8 with slot 7. Linking the two slots allows slot 7's activation to stop slot 8's playback,
and vice versa. This was designed with a specic situation in mind (but can, of course, be
used for other purposes): Replicating the way that closed hi-hats will silence open hi-hats.
Each slot can be played, soloed, muted or hot-swapped using controls that appear when
the mouse hovers over it.
22.1.2 Start, Transpose and Stretch
The Start control denes where Impulse begins playing a sample, and can be set up to
100 ms later than the actual sample beginning. The Transp (Transpose) control adjusts the
transposition of the sample by +/- 48 semitones, and can be modulated by incoming note
velocity or a random value, as set in the appropriate elds.
The Stretch control has values from -100 to 100 percent. Negative values will shorten the
sample, and positive values will stretch it. Two different stretching algorithms are available:
Mode A is ideal for low sounds, such as toms or bass, while Mode B is better for high sounds,
such as cymbals. The Stretch value can also be modulated by MIDI note velocity.
22.1.3 Filter
The Filter section offers a broad range of lter types, each of which can impart different
sonic characteristics onto the sample by removing certain frequencies. The Frequency
control denes where in the harmonic spectrum the lter is applied; the Resonance control
boosts frequencies near that point. Filter Frequency can be modulated by either a random
value or by MIDI note velocity.
