When you play the keyboard staccato you will hear a less sustained sound with a
different harmonic makeup, and the delay effect is more easily heard. Play across a
large range of the keyboard, and adjust the Cutoff Env knob to hear how this affects the
filter response.
4. Click the Effects button to view the effects section, then choose the Slapback preset
from the Delay plug-in File menu.
Play a few notes to hear the impact this has, then choose the Bandpass Ping Pong
preset.
5. Return to the performance controls, and adjust the Resonance knob while playing both
staccato and held notes.
6. Double-click both the Resonance and Cutoff Env knobs to reset them to the center
position.

2. Click the source select field for source A, then choose Load VA > Complex > Eighties

Play your keyboard to hear a more classic synth type sound. Feel free to repeat this
step with sources B and C, using different waveforms, or perhaps import a drum loop.
Mute a source to use a partial preset in Alchemy

2. Click the source A button to mute this source. A lit A, B, C, or D button indicates the
source is active.
