Corpus, Rippler, and a growing pile of modal plugins accept audio at their input, which means your own recordings can excite the model.
Most producers only ever play these things from a keyboard. Load a preset, hit a note, get a marimba. That covers maybe a fifth of what the engine is capable of.
The other route sends a signal in. Kick, snare, guitar, vocal, room tone, anything with a transient sharp enough to set the model moving. What comes back carries pitch, material, and decay that no reverb will hand you.
Modal synths are catching up on the same idea. RipplerX added audio input at version 1.4.0, so an external signal can drive its resonator pair instead of the built-in noise and mallet exciters. Send a snare loop into reFX's twelve-model Rippler engine and the same trick applies, except you can play the tuning from the keyboard while the audio keeps hitting.
Sharp material works best. Closed hats, rim shots, plucked guitar, and consonants in a vocal all give the model something to bite on. Pads and sustained synths mostly smear, because the resonator never gets a clean strike to respond to.
The practical gain is control over the tail. Decay sets how long the object rings, material decides whether highs or lows die first, and brightness moves the balance of the overtones. Three knobs, and a flat loop starts behaving like a physical object.
Corpus solves it through the sidechain section. Switch on MIDI frequency, and the resonance follows incoming notes, with a Last or Low switch to decide which note wins when chords arrive. Off Decay then mutes the ring when the note lifts, which stops long tails smearing across a chord change.
Feeding it a duplicate of your bass MIDI is the cheapest way to lock everything to key. The resonance moves with the harmony instead of parking on one pitch, and busy sections stay readable.
Without MIDI control, you are tuning by hand. The Tune knob works in hertz and the Fine knob in cents, so a chromatic tuner on the master bus beats guesswork every time.
It also generates its own pink noise, so you can build tones with nothing plugged in. Dry and wet levels are RMS matched, which keeps gain honest while you audition. Builds cover VST3, CLAP and AU across macOS, Windows and Linux, with no account and no telemetry.
RipplerX sits alongside it as a free download under GPL, and it covers the same three operating systems. Between the two, you can test whether resonated drums belong in your workflow without spending a thing, then decide later whether a commercial engine earns the money.
Gain staging matters more here than with most effects. Resonators amplify whatever frequencies they are tuned to, so a hot input turns into a spike fast. Trim before the plugin, not after, and gate the source when room noise starts ringing on its own.

Resonator models take a signal in, not just MIDI
Ableton built Corpus with Applied Acoustics Systems, and it exposes seven models covering beam, marimba, string, membrane, plate, pipe and tube. You drop it on a channel, and the incoming audio does the striking.Modal synths are catching up on the same idea.

Tuning the resonance to your track keeps it musical
Untuned resonance is the fastest way to ruin a mix. A plate ringing at some arbitrary frequency will sit against your bassline and fight it, and no amount of dry-wet blending fixes a wrong note underneath the kick.Corpus solves it through the sidechain section. Switch on MIDI frequency, and the resonance follows incoming notes, with a Last or Low switch to decide which note wins when chords arrive.

Free options cover this before you spend anything
Polarity-RES is a free resonator plugin worth grabbing before any paid one, with 32 tunable bands you place directly on the spectrum. It snaps to musical notes and harmonic series, follows MIDI, and holds or learns a spectrum from incoming sound.It also generates its own pink noise, so you can build tones with nothing plugged in. Dry and wet levels are RMS matched, which keeps gain honest while you audition. Builds cover VST3, CLAP and AU across macOS, Windows and Linux, with no account and no telemetry.
