- Multi-output. GrindSub has three output buses: the mix, and the grind and sub
paths as separate stems. Enable multi-out in your host (Logic: choose the
Multi Output version of the plugin; Live, Bitwig, Reaper, FL Studio, Cubase: the
plugin’s extra outputs appear in the routing) and the sub arrives on a bus of its
own, so your own sidechain compressor can duck it against the kick while the
grind stays put. Each stem has the Output trim and its own Ceiling, so with the
Ceiling off the stems sum to the mix exactly, and with it on every output is bounded
on its own. The sub bus is a stereo pair carrying the same signal on both sides,
because the sub is mono by construction. All three buses are stereo only: on a mono
track the host sums the pair, which loses nothing of the sub.
- The sub is mono by construction, so there is nothing to collapse below the
cleanup filter. High-pass other instruments around the sub instead of narrowing
GrindSub.
- The fundamental is one sine at a known level, not the low band of a crossover, so
when you layer another bass you are aligning against a single clean tone rather
than against a filtered stack. Alignment is still on you: the
correlation meter reads GrindSub’s own output
only and cannot see the layer or how the two sum.
- Offline bounces are bit-identical to realtime playback at the same sample rate.
If a null test against a bounce fails, the difference is upstream or downstream
of GrindSub.
