    Sine waves and MIDI IN

    Alright, for those who didn't know, please bear with me.

    :bear:

    The DX7 envelope generator behaves in a peculiar way that can be exploited as a wave sequencer. If you set the first stage of the envelope below certain (low) level, the evelope rate parameter will act as a simple delay not as a slope shaper. In other words, when you hit the key, the envelope will kick in after some time set by the rate parameter, instead of rising gradually.

    Now create up to 3 different waves, from simple waveforms to complex timbres and shape them with the remaining 3 stages of the EG that can serve as Attack, Decay or Sustain (not both) and Release for each operator. Position them on the global patch envelope that you create by summing the individual envelopes of each wave.



    Dude, that's like saying a Little Phatty can do "wave sequencing" by assigning the LFO to the waveform. Sure, it changes the waveform, but its not wave sequencing.

      I think some people are confused a bit by the terms.

      Wave sequencing refers to sample chaining/crossfading as made famous by some Korg products. Wavetable synthesis is quite different using a modulatable pointer to move through a table of single cycle waves in realtime.
      Occasionally you can get similar results from both types of synthesis but usually the results are quite different.


      Mathematically the latter technique includes the former as described above as a subset (unless there are additional subtleties), as one could move the pointer from one wave to another (or not) and cross-fade and/or chain at the same time given sufficient number of wave table oscillators and sufficient modulation control.

      ...Music can be used to stimulate mass emotion, while mathematics cannot; and musical incapacity is recognized (no doubt rightly) as mildly discreditable, whereas most people are so frightened of the name of mathematics that they are ready, quite unaffectedly, to exaggerate their own mathematical stupidity.

        Little Phatty cannot crossfade which is part of wave sequencing. DX7 is quite comfortable with it.

          Some Ensoniq gear? or wavetable?

            There are additional subtleties actually. Wave sequencing is linear while wavetables are random-access. Generally wave sequencing involves short samples while wavetables are single cycle waves...there's more but it's a PITA to type this on an iPod.

            When I get home to my puter I can pontificate more if anyone is interested.

              The closest thing from yamaha to my knowledge is the tg33 vector synth. But I'm not that familiar with their synths after the 90s. still pure vector based sound "morphing" is a lot different than wave sequencing. Ws is a technical term and refers to sample sequencing like carbon said. Arguing semantics = fail.

                The TG33/SY22 is a greatly under-rated synth that I happen to really love.

                However, this muddies the waters even more because "vector synthesis" is another form of synthesis entirely - where four sources are panned between during the duration of a note with a multiplex envelope and/or recorded joystick movement. The Korg Wavestation sported this method in addition to it's wave sequencing capabilitys. While sometimes the results can be similar to both wavetable and wave sequencing, it is not always.

                  It's a lucky coincidence that I've posted audio examples of the DX7 wave sequencing in this thread on another forum:

                  Blaster Beam Challenge!



                  Cool! I just submitted my Blaster Beam sound to that thread.
