Analog Modal Synthesis On Eurorack Modular

This second part of our series on physical modeling synthesis with eurorack modular synthesizers covers modal synthesis. Modal synthesis utilizes many resonant bandpass filters as a resonator which can then be excited by many different types of impulses or sounds. Since most modal synthesis models use dozens or hundreds of bandpass filters digital implementations are more practical, but we put this together with analog bandpass filters to see how it would work.
The quad filters we used were the Qu-Bit Tone: www.perfectcir...

Well done. So much of today's modular techniques are based on rhythms and sequences. More needs to be done in terms of complex tonality and waveform manipulation (non digital).

So cool, nice work!

[@hunterfoxen]

that was sick

[@modularben7421]

for over 12k in gear it better be good!

[@Wiktorion]

very cool and informative!

[@ComparativeIrrelevance]

Awesome stuff!

[@DaveBessell]

Very nice. If only there were some way of storing analogue presets! Tuning a lot of resonant filters by hand is pretty slow work, especially if you are obtaining the frequency values from a spectrum analysis. This method of analogue modal synthesis has so much potential but is held back I think by the difficulty in controlling it. To my ears it sounds better than the digital version.

You're 2/3rds of the way complete with the most popular physical modeling module: Rings. I'd love to see you attempt to recreate the sympathetic strings mode. Not sure how as I barely understand modal anyway but as that's arguably the most popular mode of the most popular module of its kind i think it'd be a fantastic video experiment

[@MrStognabologna]

Joseph Wright I may be wrong but isn't rings inharmonic string mode karplus strong synthesis? He did mention karplus strong in the video but I don't have a rings to confirm and I'm lazy

[@josephwright5140]

Tee Munee inharmonic string is covered, which is the red mode of rings. I'm talking about sympathetic strings, which is yellow. the former is a single string sound and the latter is several strings that are harmonic and sound much different

[@josephwright5140]

Tee Munee I'm not an expert so maybe there is very little difference under the hood but I do own rings and can tell you first hand they sound miles apart

[@PerfectCircuit]

The rings sympathetic strings mode uses comb filters according to Mutable Instrument's website, and you can create comb filters with short delays. Our other video about Karplus Strong and delay line synthesis shows how you could make something similar to the sympathetic strings mode with short delay lines and a matrix mixer.

Oh gotcha I knew I had something wrong

[@OIP_1]

i heard you like filters

[@wackenthaljef]

If i was in LA!!!...(im in Urope)

[@LavLab]

Hhhmmmmm..... 🤔

[@modularben7421]

too many wires!
