Spectrus 1.6.0 gives every rack slot access to the main input and any earlier slot, with separate level trims for each active source. The eight positions are not a fixed left-to-right chain, even though the interface can look like one at first glance. By default, every slot listens to the main input in parallel.
The Spectrus eight-slot signal routing starts making sense once you treat each slot as a destination with its own input patch. Slot 1 can only hear the main input, while later slots can listen to M, one earlier slot, several earlier slots, or a mixture of those sources.
Each lit input square has its own trim, so merging two paths does not mean accepting both at full level. You can push one branch forward, tuck another underneath, or bring the dry input back into a processed path before the next effect touches it.
Spectrus mixes slot outputs at the final stage, so a serial path can still leave earlier stages audible unless you manage their sends to the mix. Muting Slot 1 removes its direct contribution while Slot 2 continues receiving its signal. The same trick lets you mute Slot 2 and hear only the cabinet output from Slot 3 without breaking the distortion-to-amp-to-cab path.
Mute is not the same job as bypass. Use mute when a stage should keep feeding later processing but should not be heard directly in the final blend. Use bypass when you want the chain to keep passing signal while one effect is taken out of the processing path.
Slot Level works along similar lines. It changes how loudly a slot contributes to the final mix, but later slots routed from it still receive the underlying signal unchanged. Balance also affects the slot's mix contribution rather than repanning the feed sent downstream.
Spectrus lets the receiving slot trim each incoming branch separately. A louder distortion path and a quieter delay path can be balanced before they hit a shared reverb, cabinet, saturator, or other processor. Turning down the two slots at the output does something different because those slot Levels do not change what the merge point receives.
A dense rack makes this easy to misread. Audio engineers already treat multi-effect chain ordering as part of the resulting sound, and Spectrus adds source selection to the same problem. A reverb fed by distortion plus clean input behaves differently from a reverb fed only by the distortion output, even when the final loudness ends up similar.
Solo follows the routing logic too. Soloing a slot changes what you hear in the mix, but a soloed or unsoloed branch can still feed a later slot according to the routing squares. It is useful for checking one contribution without tearing apart the graph you built.
This is not interchangeable with an effect's internal Wet and Dry controls. Those controls blend processed and original signal inside the effect, while Spectrus input routing decides what signal reaches the effect in the first place. Master Dry and Wet sit farther downstream again, balancing the untouched input against the rack's combined processed output.
One safety behavior can confuse you during setup. Switch off every input square on a slot, and Spectrus does not leave the slot disconnected or silent. It falls back to the main input, with the M indicator shown differently, so an apparently unrouted processor can suddenly start receiving the original track.
Reordering deserves the same care. Dragging one effect onto another slot swaps the effects and their parameter values, but the routing, level, mute, solo, and tone settings stay attached to the slots themselves. A complicated parallel graph can survive an effect swap, although the sound may change dramatically because the new processor inherits the old slot's place in the routing structure.

Serial chains stay clean when upstream slots stay muted
A basic serial chain is simple to wire. Put distortion in Slot 1, an amp in Slot 2, and a cabinet in Slot 3, then make Slot 2 listen only to 1 and Slot 3 listen only to 2. The important wrinkle is what happens to each slot's own output.Spectrus mixes slot outputs at the final stage, so a serial path can still leave earlier stages audible unless you manage their sends to the mix. Muting Slot 1 removes its direct contribution while Slot 2 continues receiving its signal. The same trick lets you mute Slot 2 and hear only the cabinet output from Slot 3 without breaking the distortion-to-amp-to-cab path.

Parallel paths keep their own gain before a merge
Parallel routing starts with two or more slots listening to M. One branch might hold a tight distortion while another carries delay or modulation, letting both processors work from the same untouched source instead of processing each other's output. You can then send both branches into a later slot and make a proper merge point.Spectrus lets the receiving slot trim each incoming branch separately. A louder distortion path and a quieter delay path can be balanced before they hit a shared reverb, cabinet, saturator, or other processor. Turning down the two slots at the output does something different because those slot Levels do not change what the merge point receives.

Merge points happen before wet and dry mixing
Lighting M and an earlier slot on the same destination creates a merge before the destination effect. Suppose Slot 1 holds a crushed compressor and Slot 2 listens to both M and 1. Slot 2 now processes a blend of the untouched source and the compressed branch, rather than merely mixing a dry signal beside its own wet output afterward.This is not interchangeable with an effect's internal Wet and Dry controls. Those controls blend processed and original signal inside the effect, while Spectrus input routing decides what signal reaches the effect in the first place. Master Dry and Wet sit farther downstream again, balancing the untouched input against the rack's combined processed output.
