i think it’s ok to have levels at certain points within a pedalboard >0 — just from a digital DSP point of view, we have tons of headroom since it’s all at 32-bit, right?
the only caveats would be:
a particular plugin might be designed such that it distorts if signal is >0.
we need to be <0 at the input and output of the board.
plugin1 -> plugin2 |-> plugin3 -> more plugins
|-> meter
with all my plugins because it keeps the sound consistently stable — which is crucial — when it’s below ~ -20 dB (K20). The output signal is then just below 0 dB.
