Derailer is a physical modelling system built from 3 basic elements. Strings which can be plucked or bowed, metal bars which can be pitched or act as resonators, and nonlinear springs which can be used to connect resonators together to form a network. Derailer uses finite-difference time-domain numerical modelling of these elements.

Derailer uses a driver and resonator setup to provide a flexible system with a wide range of sounds. The excitation signal can be a sawtooth waveform, a plucked or bowed string, a pitched bar, or a striker. This thens passes through an EQ section and low-pass resonant filter, a diode clipper, and then a delay or gate. The resulting signal is then used to drive one of the bars of the resonator network.

The resonator is built from 5 metal bars which can be connected together by up to 10 nonlinear springs. The spring positions can be moved around to change the resonance of the network. Each bar has controls for rigidity, sustain, tone, and mass. Each spring has variable stiffness, decay and nonlinearity.

An extremely valuable addition to a sound designer's toolkit, or any fan of PM synthesis. For that matter, an excellent proof of concept or educational instrument for a newcomer to PM synthesis. That goes for any of Physical Audio's instruments.

Actually... For a good 100,200,300 level PM synth from this manufacturer, I would start here with Derailer. Then move to Preparation, and finally to Modus. They advance in sophistication, or complexity, in my opinion. There are certainly other PM synth developers that make things somewhat more accessible, but I don't think they necessarily show you what's going on under the hood as well, in general.

Nor am I claiming that other PM synths aren't amazing and must-haves, I have a solid list I certainly wouldn't do without.

I'm sure others have plenty of valid opinions on this topic.

Anyway. Check this out.

(I'm not employed by them or endorsed or whatever, I just love their products).
