The Osc tab contains the oscillator parameters and settings.

Title Bar Controls

Wave/Spectrogram Opacity

The display at the top of the section allows you to show the sample waveform or a spectrogram of the sample, or a mixture of both. You can blend these two representations using the Wave/Spectrogram Opacity slider.

Drag the slider all the way to the left to show the sample waveform in the display. Drag it all the way to the right to show the spectrogram. Settings in between show both the waveform and the spectrogram superimposed onto each other.

Trigger Note on Click in Sample Display

Allows you to start playback of the sample by clicking in the waveform display.

Load/Replace Sample

Allows you to load an initial sample or to replace the current sample.

In the Load dialog, you can preview the samples.

Parameter Section

Legato

If Legato is deactivated, each note is played back from the position cursor.

If Legato is activated, the first note is played back from the position cursor, and playback of any subsequent notes starts at the current playback position, for as long as the first note is held.

This allows you to you add further notes, all of them synchronized with respect to their playback position. As long as you play notes legato, the oscillator continues to run, which allows you to switch between chords without restarting the oscillator.

Hold Last Spectrum

Activate Hold Last Spectrum to keep the last spectrum, once sample playback reaches the sample end or sample start, depending on the playback direction. This is especially useful if Sustain Mode is activated for the amplifier envelope, because the last spectrum acts like a single-cycle loop that can be played for as long as a key is held.

Channel Spread

Shifts the playback position for each channel of the sample.

  • For stereo files, positive values modify the playback position of the right channel, and negative values modify the playback position of the left channel. In both cases, the other channel is not affected. This can be used to widen the panorama of the sound.

  • For mono files, the oscillator creates a copy of the channel. This allows you to create a stereo sound from a mono sample, for example.

  • For surround files, the front left and right channels are shifted in the same way as stereo files. The shift for the rear channels is twice as large. The center and the LFE channels are not shifted and remain in their original position.

Direction

Allows you to set the playback speed in smaller increments. Furthermore, this parameter determines the playback direction.

  • If you enter negative values, you reverse playback, that is, the playback position moves backward through the sample.

Random Direction

Adds a random negative or positive value to the current direction when you play a note.

For example, if you want the direction to vary between -100% and +100%, set Direction to 0.0% and Random Direction to 100.0%. If you want the direction to vary within the full positive range, set Direction to 50% and Random Direction to 50%.

Position

Determines where playback starts. You can also click in the sample display to set the position.

Random Position

Adds a random value to the current position when you play a note.

For example, if you want the position to vary between 25% and 75%, set Position to 25% and Random Position to 50%.

Speed

Adjusts the playback speed of the sample. A setting of 800% equals an increase of three octaves in pitch. A speed of 0% plays a static spectrum at the current position.

Note

If you change the Speed parameter, you may need to manually adjust the envelope length on the envelope pages.

Acceleration

Allows you to specify the time it takes to transition from the initial playback speed set with the Speed parameter to the set Target Speed.

Higher values result in faster transitions, lower values in slower transitions. With Acceleration set to 0, the initial speed remains constant.

Target Speed

Allows you to specify a target playback speed. The time it takes to reach this speed depends on the Acceleration setting.

Speed Key Follow

Determines how the Speed parameter is scaled by the keys that you play. With a value of 0, the speed is the same for all keys. Positive values increase the speed for keys above the Center Key and decrease the speed for keys below the Center Key. Negative values decrease the speed for keys above the Center Key and increase the speed for keys below the Center Key.

For example, with Speed Key Follow set to 100 and Center Key set to C3, playing a note one octave above C3 doubles the speed, and a note one octave below C3 halves the speed.

Sync to Tempo

Allows you to synchronize the playback speed to the tempo of the host application.

If Sync to Tempo is activated, the playback speed is determined by the Speed parameter and the tempo of the host application.

If Sync to Tempo is deactivated, the playback speed is exclusively determined by the Speed parameter.

Sync Mode
  • If Sync Mode is set to Tempo, the playback speed is calculated based on the ratio between the original tempo of the sample and the tempo of the host application.

  • If Sync Mode is set to Beats, the playback speed is calculated based on the note length of the beats, the number of beats, and the tempo of the host application.

Auto Gain

Allows you to automatically adjust the level of quieter sample parts.

Note

By raising the gain, you risk losing the dynamics of the sample.

Level

Adjusts the output level of the oscillator. This can be used to compensate for level losses or increases caused by the spectral filter, for example.

Width

Narrows the stereo width of the oscillator. At a setting of 0%, the output of the oscillator is mono.

Snapshot

The Snapshot function allows you to create dense, evolving drone textures. It captures spectra at specific time intervals. These spectra are then smoothly interpolated over the set duration. You can specify how many snapshots are captured while a note is playing, and crossfade back and forth through the resulting snapshot sequence.

Snapshot On/Off

Activates/Deactivates the Snapshot function.

Snapshot Mode

Determines how spectra are captured and how the interpolation is performed. In all modes, an initial spectrum is captured when a note is played.

  • Periodic: After the first spectrum is captured, a timer is started. When the timer expires, a new spectrum is captured, and the sound gradually transitions from the previous spectrum to the new one over that time. This process repeats continuously for as long as the note is held. You can set the duration of the timer with the Snapshot Time parameter.

  • Random: After the initial capture, spectra are captured at randomly varying intervals. At the end of each interval, a new spectrum is captured and the output smoothly interpolates to it. The process is then repeated with a new random interval. You can set the maximum interval duration with the Snapshot Time parameter.

  • Manual: The first spectrum is captured immediately and held. When you click Capture, a new spectrum is taken, and the sound gradually transitions to it over the time set by the Snapshot Time parameter, then freezes. To start another transition, click Capture again.

Capture

Captures a new spectrum immediately and restarts the Snapshot Time interval for the modes Periodic, Random, and Manual.

Note

Freeze is automatically deactivated when Capture is triggered.

Note

Capture is available as a destination in the modulation matrix. It is triggered on the rising edge of a modulation signal.

Freeze

Stops the current interpolation and freezes the sound at its current state. Interpolation resumes when Freeze is deactivated.

Note

Freeze is available as a destination in the modulation matrix.

Auto Freeze

Freezes the sound after the snapshot sequence reaches the number defined by the Number of Snapshots parameter.

Snapshot Sync

Allows you to synchronize the Snapshot function to the host tempo.

If Snapshot Sync is deactivated, the interval is specified in milliseconds and runs independently of the host tempo.

Snapshot Sync Mode
  • Tempo: The interval is calculated from the selected note length and the current host tempo.

  • Tempo + Beat: The interval is calculated from the selected note length and the current host tempo. In addition, snapshots are aligned to the beat positions of the host timeline. This ensures consistent timing across all voices without requiring the activation of the Single Timer parameter.

Snapshot Time

If Snapshot Sync is deactivated, this parameter sets the duration of the interpolation between spectra for the selected Snapshot Mode.

  • In Periodic mode, this parameter sets the interval for the capture–interpolation cycle.

  • In Random mode, this parameter defines the maximum duration of each random capture–interpolation cycle.

  • In Manual mode, this parameter defines the interpolation time between manually captured snapshots.

Note

In the modes Periodic and Random, the Snapshot Time parameter also sets the interval between successive captures.

Note

Spectral Snapshot Time is available as destination in the modulation matrix.

Snapshot Single Timer

If this button is activated, a single timer is shared across all voices. The first note starts the timer, and any subsequent notes sync to it. As a result, all voices capture and interpolate in unison.

Snapshot Sync Note

If Snapshot Sync Mode is set to Tempo or Tempo + Beats, this parameter sets the interval as a musical note length. You can also set dotted and triplet note values.

Number of Snapshots

Sets the maximum number of spectra that are captured for a note. The maximum setting is 8. While a note is playing, the spectral oscillator captures snapshots sequentially, according to the selected Snapshot Mode, filling the sequence one by one. When the note ends, the sequence is cleared.

Snapshot Fade

Crossfades through the sequence of snapshots captured so far during the note. At the start of the note only the initial spectrum is available. As new snapshots are captured, the crossfade range extends through the growing sequence.

Note

This parameter is only available if Number of Snapshots is set to a value above 1.

Note

Snapshot Fade is available as a destination in the modulation matrix.
