Strum

Sound Strummer

strum audio plugin
Strum is an intuitive multiband delay.

Designed to make spectral delays easier to use, Strum splits your signal evenly and cleanly into a bunch of different bands, and then allows you to control the delay time & feedback of each band.

Strum can work either in “free” or “sync” mode, where in “sync” mode each individual band’s delay time is synchronized to the tempo & time signature of your DAW, allowing for rhythmically-aware strumming.

Additionally, Strum provides  a modulation panel for a bit more control of the delay times, allowing you to switch between “flutter” and “random” modes.

  • Modulation Skew

    Strum allows you to "skew" (or bias) the modulation based on frequency. Enabling the skew link & then adjusting the skew knob can increase / decrease the frequency / depth of your modulation as the frequency changes.

  • Factor Band Control

    Similar to Sweep and Recurse, Strum features a "Factor Band" control system where points are adjusted similarly to how an EQ would be adjusted, giving you comprehensive control over the frequency range.

  • Dynamic Crossover

    Strum's multi-crossover system makes use of a proprietary filter bank which has both a flat frequency and phase response. Rest easy knowing that Strum isn't coloring your sound at all when it doesn't need to be.

  • Overlay Adjustment

    Just in case the overlay that changes as the delay time & feedback are changed seems a bit too much to look at, you can go into the menu (by clicking the Lese logo) and disable it. We'll still show you where the bands are split at, though.

strum tutorial

  1. Factor Band Control. This displays the delay overlay, the factor band curve, and the audio spectrum (if metering is enabled). You can drag the circles to move the factor bands around, and adjust the bandwidth by scrolling.
  2. Factor Band Enablement. You can enable any of the factor bands you like in this section, and each band has it's own pre-defined shape (as displayed in the icons adjacent to the buttons).
  3. Factor Band Parameters. The factor bands (also called control points) are defined in a way similar to filters in an EQ. This section controls the frequency, the amplitude, and the bandwidth (click+drag them as you would with sliders to adjust them, or type in a value).
  4. Flip Controls. This button inverts the Y-axis (up & down) of the control points, for the cases where you couldn't get what you want otherwise.
  5. Dynamic Crossover Skew. This is a slider that changes how the distribution of the dynamic crossover works. At center, the filter bands are evenly distributed accross the frequency spectrum, when you move it left & right, the bands become more bunched up in the lower & higher frequencies (respectively).
  6. Delay Time / Feedback Control Switch. This button switches what set of factor bands the interface is displaying, and what ones you are controlling.
  7. Delay Bands. This knob controls how many delay bands are being processed.
  8. Sync Mode. This button turns Strum from a free-time delay system into a sync-time delay system. Each band will be constrained to a tempo-synchronized value as defined by (9) the max number of delay steps and (12) the divison.
  9. Max Delay. This knob controls the maximum possible delay value settable via the factor bands. if (8) Sync is enabled, this changes to the maximum number of synchronized steps available to be set by the factor bands.
  10. Modulation Rate. This controls the rate of the modulation. Either directly in Flutter mode, or more of a value of movement speed in Random mode.
  11. Modulation Amount. This controls the amount (or depth) of modulation fed into each delay band's delay time values. When at 0%, modulation related controls will be disabled.
  12. Synced Division. This determines what kind of note division will be used when in (8) Sync mode. When Sync mode is off, this knob is disabled.
  13. Modulation Rate Skew Toggle. This toggles if we will (14) Skew the (10) Modulation Rate.
  14. Skew. This knob determines if we are skewing (adding or subtracting bias to / from) the Modulation Rate and Amount parameters based on a delay band's frequency. As the knob turns to the negatives, the lower frequencies will be more affected by whichever modulation parameter is allowed to be affected, and vice versa for turning it positive.
  15. Modulation Amount Skew Toggle. This toggles if we will (14) Skew the (11) Modulation Amount.
  16. Modulation Mode. This switches between "Flutter" mode (where modulation is cyclical, or like a sine wave) and "Random" mode, where modulation is.. well.. random.
  17. Dry / Wet Mix. This determines the dry / wet mix of the plugin.

  • Windows: VST3
  • OSX (Intel / ARM): VST3, AU

Should run fine on any recent operating system. Check the FAQ for installation troubleshooting.
