Not true. Most of whether a synthesizer is fat and warm or thin and tweazy is determined at the output of the oscillator. I haven't yet done an FFT of various models, but I'll wager that the relative level of the fundamental and the first few harmonics to the other overtones is greater on some designs than it is on others. IOW, more fundamental and less relative overtones equals fatness. Also, the SEM is a good example of oscillator character. They have a bad ground scheme (according to Tom Oberheim), and the 60-cycle modulation produces a rattier set of harmonics than a perfect design. It should be easy to hear the difference in two detuned square waves from an SH5 and a Buchla 100, for instance. Waveshaping circuitry makes a difference in a waveform's harmonic content, so simply by fact of different design approaches, the majority of discrete synths should sound a bit different even before the filters. > Most owners of 10K Moogs and System 700's will find it hard to accept >that something costing 10 times less is as good as their vintage monster - I >have a collection of modulars here in the Synth Museum, but guess which >system is in the studio! > >Andy Horrell It always comes down to what kind of sound or what kind of control you want to generate. Some synths excel where others are weak. I'd have no problem adding a few Doepfer panels to my Moog, and using it when dictated by the desired sonic character/controller configuration. Use what's appropriate. Note that this does not include modules with curtis chips. You all know how I feel about them... easier, mike ________________ Specifications: Signs and Portents/Buh Bye Newt ya Hump/Evolution in Action Mark Mothersbaugh on "Rugrats": "The kids are like the cutest little tumors you ever saw."
