Physical modeling tone generator
I'd love to see is a Reason instrument designed to work like the Yamaha VL-70m or the Wallander Instruments VST's.

The goal is very small, efficient playable instruments with the expressiveness and behavior of a real instrument (and compatibility with wind controllers).

Anyone that's ever played a sax through a sampler is aware of it's shortcomings. Even with a wind controller, it just doesn't sound right.

Create this and I'll be the first one in line for the Reason Jazz Band refill.

Check out the Wallander Instruments site for an idea of what is possible. I've heard an early sample MP3 of some saxes being played through via software and it's by far the best sounding virtual sax I've heard to date. (The woodwind instruments are coming out soon. Right now they just have the brass section up).


I believe this will be the future for reproducing real instruments, as it doesn't require a lot of overhead, there are no huge sample libraries required, and the instruments are a lot more expressive (when played live) and natural sounding.

In the event that this idea doesn't take off, put me down for 1 order of a high quality hyper-sampled Reason Saxophones refill please. :)

Re: Physical modeling tone generator
: This rather new technique of sound generating can already be done in reason with a few limitations

I propose to first get an idea of what physical modelling is :

I have made a small example using this technique. take a look at:

best regards,

Re: Physical modeling tone generator
I'm still on version 2.5 until 4.0 ships so I'm unable to check out the example, but I have it downloaded and will try it out in a couple of weeks.

Thanks for the feedback.

Re: Physical modeling tone generator
Cannot view your file right now, but will do tonight.

At a glance the process seems very harsh on ressources (specially more advanced techniques using FE analysis), which goes totally against propellerhead's policy (until now) of softwares that run on lower end machines.

Re: Physical modeling tone generator
It is just a simple demonstration of what reason is capable of beyond the normal usage of osc,filters etc...

But don't expect too much. It was a first kind of a new generation of synthesizer i was trying to build.

Re: Physical modeling tone generator
Could you provide some more details on the way you tuned it actually?

based on a physical model, I guess:
- the comb filter comes in for resonance of some part of the instrument
- reverb for inherent reverb inside the instruments
- scream 4 bodies resonances some other reverb in the instrument?
- am not sure about the reason for the choice of a sawtooth oscillator, as it doesn't seem a natural type of vibration
- pink noise, overdrive and tape screams for inherent / natural instruments defect?

Re: Physical modeling tone generator

I have posted a new thread in the general forum

Since this is more about a technique and not specifically a feature request.
