| </header> | ||
| <section><p>The Curve Sequencer modules are deprecated. | ||
| This guide explains how to convert a Curve Sequencer preset | ||
| to use a <a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer>Sequencizer</a> instead.</p> | ||
| <p>The key differences between Curve Sequencer and Sequencizer:</p> | ||
| <ul> | ||
| <li>Curve Sequencer uses <a href=#converting-generate-modes>“generate modes”</a> to specify the starting and ending voltages for each step. Sequencizer uses two flexible voltage sources called “anchors,” one defining the step’s starting voltage and the other defining the ending voltage.</li> | ||
| <li>Curve sequencer uses <a href=#converting-advance-modes>“advance modes”</a> to define the conditions under which the sequence exits the current step and advances to the next. Sequencizer uses a flexible combination of trigger, interrupt, and sustain controls to determine when the sequence advances.</li> | ||
| </ul> | ||
| <p>See:</p> | ||
| <ul> | ||
| <li><a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer/>The Sequencizer Modules</a> for detailed descriptions of Sequencizer’s controls.</li> | ||
| <li><a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer/user-guide>Sequencizer User Guide</a> for ideas about how to use the Sequencizer modules.</li> | ||
| </ul> | ||
| <h1 id=converting-generate-modes>Converting Generate Modes</h1> | ||
| <p>In Curve Sequencer, the generate mode determines what kind of curve the step produces. In Sequencizer, the curve is determined by the START and END anchors, each of which has a source (LEVEL, A, B, C, or OUT) and a mode (SMPL or TRACK).</p> | ||
| <h2 id=generate-mode-curve>Generate Mode: CURVE</h2> | ||
| <p>In Curve Sequencer, curve mode generates a curve starting from whatever voltage the sequencer was emitting when the step started, and prograssing to the voltage set by the <em>LEVEL</em> knob.</p> | ||
| <p>To achieve the same effect in <a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer>Sequencizer</a>: | ||
| <img class=controls style=width:20mm src=curve-mode.png alt="Curve Mode"></p> | ||
| <ul> | ||
| <li>Set the <strong>START</strong> anchor to SMPL OUT. When the step starts, it samples the voltage at the OUT port, and progresses from the sampled voltage.</li> | ||
| <li>Set the <strong>END</strong> anchor to TRACK LEVEL, and set the end LEVEL knob to the desired voltage. The step progresses to the voltage set by the LEVEL knob.</li> | ||
| </ul> | ||
| <h2 id=generate-mode-hold>Generate Mode: HOLD</h2> | ||
| <p>In Curve Sequencer, hold mode emits whatever voltage the sequencer was emitting when the step started.</p> | ||
| <p>To achieve the same effect in <a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer>Sequencizer</a>: | ||
| <img class=controls style=width:20mm src=hold-mode.png alt="Hold Mode"></p> | ||
| <ul> | ||
| <li>Set the <strong>START</strong> and <strong>END</strong> anchors to SMPL OUT. When the step starts, it samples the voltage at the OUT port, and emits the sampled voltage throughout.</li> | ||
| <li>Turn <strong>INT</strong> Off. The step ignores the GATE input, and continues for the step’s full duration.</li> | ||
| <li>Turn <strong>SUST</strong> Off. When the current step’s duration elapses, the sequence automatically advances to the next step.</li> | ||
| </ul> | ||
| <h2 id=generate-mode-sust>Generate Mode: SUST</h2> | ||
| <p>In Curve Sequencer, sust mode emits whatever voltage the sequencer was emitting when the step started.</p> | ||
| <p>To achieve the same effect in <a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer>Sequencizer</a>: | ||
| <img class=controls style=width:20mm src=sust-mode.png alt="Sustain Mode"></p> | ||
| <ul> | ||
| <li>Set <strong>TRIG</strong> to the desired gate condition. When the GATE input matches the condition, the step generates an internal trigger. For a traditional sustain mode, set this to LOW. But you can choose to advance on another GATE condition.</li> | ||
| <li>Turn <strong>INT</strong> On. When the step generates an internal trigger, Sequencizer interrupts the step and advances to the next.</li> | ||
| <li>Turn <strong>SUST</strong> On. When the current step’s duration elapses, the step continues to emit the sampled voltage until interrupted.</li> | ||
| <li>Set the <strong>START</strong> and <strong>END</strong> anchors to SMPL OUT. When the step starts, it samples the voltage at the OUT port, and emits the sampled voltage throughout.</li> | ||
| </ul> | ||
| <h2 id=generate-mode-input>Generate Mode: INPUT</h2> | ||
| <p>In Curve Sequencer, input mode emits the voltage at the IN port.</p> | ||
| <p>To achieve the same effect in <a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer>Sequencizer</a>: | ||
| <img class=controls style=width:20mm src=input-mode.png alt="Input Mode"></p> | ||
| <ul> | ||
| <li> | ||
| <p>Set the <strong>START</strong> and <strong>END</strong> anchors to TRACK A. The step emits the voltage at the A input port.</p> | ||
| <p>You can also use the B or C input ports. Just set both the START and END anchors to TRACK the same input.</p> | ||
| </li> | ||
| </ul> | ||
| <h2 id=generate-mode-chase>Generate Mode: CHASE</h2> | ||
| <p>In Curve Sequencer, chase mode “chases” the input by progressing from the sequence’s current voltage to the voltage at the IN port.</p> | ||
| <p>To achieve the same effect in <a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer>Sequencizer</a>: | ||
| <img class=controls style=width:20mm src=chase-mode.png alt="Chase Mode"></p> | ||
| <ul> | ||
| <li>Set the <strong>START</strong> anchor to SMPL OUT. When the step starts, it samples the voltage at the OUT port, and progresses from the sampled voltage.</li> | ||
| <li>Set the <strong>END</strong> anchor to TRACK A. The step progresses toward the voltage at the A input port. You can also use the B or C input ports.</li> | ||
| </ul> | ||
| <h1 id=converting-advance-modes>Converting Advance Modes</h1> | ||
| <p>In Curve Sequencer, each step’s advance mode determines when the sequence advances from the current step to the next. In Sequencizer, advancement is controlled by the TRIG, INT, and SUST controls.</p> | ||
| <h2 id=advance-mode-time>Advance Mode: TIME</h2> | ||
| <p>In Curve Sequencer, time mode causes the step to proceed for its full duration, regardless of what happens at the <em>GATE</em> input. The sequence then automatically advances to the next step.</p> | ||
| <p>To achieve the same effect in <a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer>Sequencizer</a>: | ||
| <img class=controls style=width:20mm src=time-mode.png alt="Time Mode"></p> | ||
| <ul> | ||
| <li>Turn <strong>INT</strong> Off. The step ignores the <em>GATE</em> input, and continues for the step’s full duration.</li> | ||
| <li>Turn <strong>SUST</strong> Off. When the step’s duration elapses, the sequence automatically advances to the next step.</li> | ||
| </ul> | ||
| <h2 id=advance-mode-rise-fall-edge-high-and-low>Advance Mode: RISE, FALL, EDGE, HIGH, and LOW</h2> | ||
| <p>In Curve Sequencer, when the <em>GATE</em> condition matches the selected advance mode, the current step is interrupted, and the sequence advances to the next step.</p> | ||
| <p>To achieve the same effect in <a href=https://dhemery.github.io/DHE-Modules/modules/sequencizer>Sequencizer</a>: | ||
| <img class=controls style=width:20mm src=interrupt-mode.png alt="Interrupt Mode"></p> | ||
| <ul> | ||
| <li>Set <strong>TRIG</strong> to the desired condition. When the <em>GATE</em> input matches the condition, the step generates an internal trigger.</li> | ||
| <li>Turn <strong>INT</strong> On. When the current step generates an internal trigger, Sequencizer interrupts the step and advances to the next.</li> | ||
