3. ATTACK
Set the Attack phase of the amplitude envelope. The Amplitude Envelope defines how loud a note
sounds over the course of its existence. Phases include Attack-Decay-Sustain-Release, or ADSR for short.
ATTACK DECAY SUSTAIN RELEASE
KEY PRESSED KEY RELEASED
When the knob is at full left, the attack is 28 milliseconds long, which is actually very short. This gives
a percussive “instant-on” sound. (We chose to set the minimum Attack to 28 instead of zero because
at zero the synth produces an undesirable click. We set the minimum attack to eliminate the click.)
At full right, the attack is 2.5 seconds, longer than you are likely to need in most cases.
The Decay phase is preset. It is very short, and it does not actually decay; the amplitude remains
constant during the Decay phase. You can edit this! See “Programming The Macchiato Mini-Synth”
below.
4. RELEASE
At full left, the Release is set to 25 milliseconds for a snappy, “instant-off” sound. (We set minimum
Release to 25 ms instead of zero because at zero, an unpleasant click is audible.) At full right, the
maximum release is 3.0 seconds for a luscious, airy fade-away feel.
Between Attack and Release is the Sustain phase. This is what is happening when you simply hold a
key down. Your Macchiato is programmed for an unchanging amplitude while you hold the key. The
note will continue to sound at full volume for several minutes and then spontaneously enter the Release
phase. You can edit this behavior! See “Programming The Macchiato Mini-Synth” below.
The Macchiato exhibits an unusual playback characteristic when using long attack and release settings.
With the synth at rest, the first and second notes you play will always fade in from silence, as you
would expect. Subsequent notes will usually begin the attack phase using the amplitude value of the
previous note at that moment. Therefore, if you set up a sound with both a lengthy attack and release,
then by the time your finger plays the third note, the second will have faded away only a little bit; the
third will start at near-full volume. Release all notes and the behavior starts over. This can make the
Macchiato surprisingly expressive. A phrase may open with a slow attack, but the subsequent melody
is much more articulate than expected. Try it!
