Yoko Band-Splitter

Yoko is the essential tool for creating unique multiband effects within Reason.

It splits an audio signal into low, mid, and high frequency bands, each equipped with gain control and stereo metering. Fully featured CV input and variable levels of cutoff slope allow for surgical precision and modulation, making Yoko an effect of its own and a powerful tool when used within a chain.

Yoko: Multiband Everything.

Unlike some splitters, Yoko is specially designed to ensure a “flat sum” all-pass crossover for each frequency band, meaning it won’t add unwanted filtering to your sound*. What you put in is what you get out, only split in three and amplified how you like.

*all-pass filtering is not phase linear, and will therefore change the phase of the signal (although this is usually inaudible)

Multiband Everything: Send each band into its own distortion while modulating the cutoff frequencies to create otherwise impossible timbres. Use separate compression on each band to place it perfectly within a mix. Put reverb on only the lowest or highest part of a signal to create surreal sonic images. The possibilities are endless.

2nd, 4th, 8th, and 12th-order Linkwitz-Riley crossover filters create 12db, 24db, 48db, and 72db per-octave slope at each cutoff frequency. Use 12db for smooth, seamless transition between each section or use 72db for razor sharp splits.

Stereo metering on each frequency band allows you to quickly see how the signal is being divided.

A stereo “sum” audio output adds all three frequency bands, turning Yoko into a flat-sum, 3-section, CV-controllable equalizer.

Solo buttons on each band let you mute unnecessary sections.

Set the high cutoff frequency all the way up to use Yoko in 2-band, “bass-effect” mode.

Return inputs allow you to quickly and conveniently add separate FX on each summed frequency band, instead of having to manually route them through a mixer.

Dynamic CV mapping ensures that unwanted low-high cutoff frequency crossings are avoided while still allowing the maximum possible range of control.

Yoko has been fully optimized for each slope level, ensuring the lowest CPU toll possible, keeping processing available for other effects.

CHANGE LOG:
Version 1.1 of Yoko adds the most requested feature from the User Forum: Return Inputs!
Version 1.1.1 fixes a silence detection bug.
Version 1.2 adds a 12 dB/Oct slope mode. Automation parameters are now grouped together in menus for easier navigation.
