The VFX-SD has something like 100 basic waveforms, and while some are sample-based, some are purely synthetic (you've got all your standard waveforms here). The Yamaha's synthetic waveforms are interesting but could hardly be said to represent more of a "synthesis from scratch" philosophy than the VFX. >Most Ensoniq's have an "extrapolate" function that creates a scale in this >manner and compiles it to the full keyboard tuning.

There's also an "interpolate" function which should allow you to program any equal tuning as follows: Tune a note N keys above a starting note to a pitch an octave (or non-octave) higher than the orignal note, interpolate, and then extrapolate. That's all! However, the procedure will alter the pitch of the higher note so that all the steps are equal, whole numbers of cents (or something like that), which can be very annoying. Even worse, the interpolation will sometimes turn inside-out, so that the pitches will decrease as one goes up the keyboard from the lower note, very low notes giving way to bleeps and blurps near the middle of the interpolation zone, and these giving way to some very high pitches which decrease until one reaches the higher note.
