Version 3.0 Bug?

      152.163.207.37 writes:

      I use the K5000S, and after installing the new 3.0 operating system, I've noticed
      that sometimes when playing an arpeggiator, a note will drone (even after
      the arpeggiator is turned off) until I find the note that is stuck and press
      it, or until I switch the patch.

      Is this a bug in 3.0, or is there something wrong with my OS disk or the synth
      itself?

resynthsis through SoundDive

      I just got my k5000 and here's my first round o questions . . .

      I've been reading message posted to Analogue Heaven about the K5000 resynthesizing
      samples into additive patches. Is this true? How do you do it? I've got
      the Sound Diver K5000 edition that came with it and the Memory Exapansion and I
      can't figure it out.

      Also can you change the Resonance while holding down a note? The Resonance macro
      knob only seems to work after you retrigger a key, however if you
      assign Resonance as one of the destinations of the User Macro knobs then it seems
      you can modulate Resonance while holding down a note. Is this right?

      Is there a multi-mode on the thing. Is the only way to achieve multi-timbrality
      through setting up multi-patches?

SoundDiver Fix List
 Sunday, 21-Dec-97 22:40:30

      Message:
      199.86.47.2 writes:

      In no order:

      1) The "5ths" edit group is a random group of overtones--none of them are fifths,
      and they don't have any relationship to each other. The "Octaves" group is
      correct.

      2) If you open another program while running SoundDiver in Windows 95, the only
      way to get SoundDiver back is to minimize everything else. Don't click
      on the button on the bottom bar or SoundDiver goes comatose; you have to
      Ctrl-Alt-Del to shut it down and then restart it.

      3) Anyone know how to stop the thing from cutting out for backup every two minutes?

      4) If you're in a number box, how about letting you enter a number by typing a
      number? Instead, the number keys are being used as hot keys for some
      reason, so you go flying all over the program. Very anti-intuitive.

      Also, like I posted before,

      5) The "evens" and "odds" edit groups are misnamed: switch the names.

      I was going to call this a gripe list, but considering how well the K5k and
      SoundDiver do work, I'm not that bitter. For something so complicated it's
      amazing how accesible it is.

      Can't think of any complaints with the K5k! Although . . . it would be nice to
      be able to expand the PCM library.

KS Pitch and "stretch" tuning
Friday, 30-Jan-98 14:48:54 

     130.67.0.151 writes:

     First of all, does anyone know what is the pivot note for normal Key Scale? Is it
     C4 (middle C, one-line C)? I cannot find this documented in the manual.

     Then, under DCO, page 30, it says that KS Pitch can be used to play in quarter-
     tones, or to add "stretch" to the tuning. Quarter-tones work fine, but I cannot
     see that "stretch" is possible. Is this a bug in the opsys or a bug in the manual?
     Or am I missing something?

     It's not in front of me, but I know there's a setting for how much the pitch

     Playing around with it, the only alternate interval between notes I can get out of
     the K5000 is in the range of 0 - 50 cents, which is really much less useful than
     it should be. I'll make sure to adding stretch tuning to the wishlist when I get
     around to creating it.

     Also, a quick check for the "pivot note", if I understand you correctly, gives
     me (oddly enough) the "E3" note.

     That means, if I put the K5000 in fixed note mode and set it to E3, I can change
     the "KS Pitch" parameter and the pitch doesn't change (which doesn't
     happen with any other key).

     Once again, I don't have it in front of me, but I looked at the Sound Diver screen
     the other night and it looked like you could set both the pivot note and the
     interval. The controls are the two boxes on the Sound Diver screen that are above
     the boxes that have the pitch envelope values. This would let you fix a
     constant note (a drone) on any note.

     I just checked it to make sure, but the Sound Diver settings do exactly the same
     thing as the settings in the K5000. The constant note can be changed, but the
     key on the keyboard which the key scaling diverges from is the E3 key (E3 is the
     key which will actually play the constant note and from which the note values
     of other keys can be calculated). Also, the key scaling still only goes up to a
     maximum of 50 cents - a quartertone. It looks like the K5000 can't do stretch at
     all!

Rates in the guise of time values

     130.67.1.177 writes:

     leiter@skypoint.com wrote:

     QUOTE

     Also, re the envelope parameters: it helped when I figured out that the time
     parameter is a rate, not a duration. If you change the level and you want the
     duration to stay the same, you have to change the rate to match. I don't know
     which way would be better, but there it is.

     UNQUOTE

     The time parameters seem to be some sort of inverse rates. Here's my latest
     experiment with the DCA Envelope.

     Set Decay1 Time and Decay1 Level to the values below and set the other parameters
     to 0. Trying to measure time by counting beats for the duration of the
     tone, I get the following results:

     D1T D1L Time Proportion

     127 124 11 1/2
     126 124 7 1/3
     125 124 5 1/4
     124 124 4 1/5

     The resulting time function is probably more sophisticated than the simple fractions
     I have listed above, but it does look as if Time is proportional to 1/(129 -
     D1T). Anyone got a better idea or more solid information?

     In any case, Time appears to be proportianal to (127 - D1L), so "rate" is probably
     the right word, as leiter says.

     Hmm... this throws a different light on the DCA envelopes. Is it the same "rate
     algorithm" as in the ADD/DHL envelopes after all? How can they keep the
     envelope on a constant value then? Can they? - I didn't test it. (See "Rate
     parameters of harmonics envelopes" thread.)

     There is another similarity of these envelope generators: I observed that both
     the DCA_Key_Scale_To_Envelope_Level and the ADD_DHL_Key_Scale_To_Gain parameter
     seemingly do not function (at least in some cases). 

     Is this a bug? - What do you think?

     Meanwhile, have any of you found a way to translate DCA Envelope settings into
     Harmonic Envelope settings? Not to mention a similar translation for the
     DCF Envelope. Figuring out this machine will take some time...

KS to Gain once again
Sunday, 15-Feb-98 08:25:32 

     130.67.1.73 writes:

     Experimenting with a piano sound, I just could not understand why the tone was
     so mellow. After careful comparison with other sources I finally found the
     culprit: KS to Gain in the DHL Common screen was set to +45. Reducing it to 0
     or some negative value cleared up the sound and brought back the high
     harmonics.

     This has been mentioned before, but some explanation for things like these is on
     the very TOP of the wishlist as far as I am concerned. Is there anything in the
     words "KS to Gain" to tell any of you that this is really a brightness control?

     Whether or not this is a bug is not my prime concern. What I want is
     DOCUMENTATION so that I don't have to waste time on things like that. 
     Besides info on "hidden features" like this one, we sorely need some documentation
     on the finer details of rates and levels. It is probably too late to ask for
     times instead of rates, but if there is some free program memory left for extra
     features, I wish Kawai would let us have parallel screens with times (possibly
     logaritmic ones) in them.

Do you hear these bugs?
Saturday, 21-Feb-98 12:52:47 

     130.67.64.133 writes:

     Some of you may have downloaded and tried Kenji's Hammond patch. If I play this
     patch, there is a curious variation in the amount or amplitude of the low
     harmonics. Play e.g. the note C5 (i.e. two-line C) over and over again. What
     I hear is not a constant tone, but a random fluctuation between C5 and C6. That
     is, the low harmonics seem to drop out once in a while. 

     This phenomenon appears to occur only if at least two of the three voices in
     Hammond are active. I cannot make it happen with one voice only. Do you hear
     the same thing? This seems like a bug to me. 

     Another bug that some of you may have noticed is that the effects are not active
     immediately when you pick a new patch. They come only on the second note
     played. Do you hear this too?

     153.37.9.106 writes:

     I don't seem to notice this phenomenon. Can anyone else verify this problem?
     What I do hear is that if you hit the note harder, I think it's the octave harmonic
     that get's louder, although I don't notice any change in the basic frequency. This
     makes the note a tiny bit brighter at harder velocities, although really it's barely
     perceptible. My K5000 also has a broken right output though so maybe it's a problem
     with stereo imaging that I can't hear (even though this seems unlikely)?

     About the reverb problem, really this is something I've noticed is common for
     digital processors. It's not that it waits for a second note, but that it takes the
     effects unit a bit of time to load the new effects settings into memory and
     initialize them, or something like that. My Ensoniq DP/2 effects processor does the
     same thing. This means that if you want to be able to change patches immediately
     on the K5000 you really need to do something with the multi-mode, the
     problem here of course being that all of the sounds run through the same effects
     (although they can take different paths, but you still need to reprogram all of
     the effects). My opinion is that this is a completely unsolvable problem that
     you will encounter on most devices with digital processing.

     I reduced the patch ("Hammond2") to the bare essentials: I retained source 1 and
     2 only, switched all effects off, set the effect control depth to zero - and
     could hear that phenomenon even better than before! 

     My explanation: The dynamic voice (or "source") assignment of the synthesis software
     starts the 2 sources with a little delay. This delay is not constant, so the
     phase relations between the sources vary from note to note. In this case, the
     sources 1 and 2 are identical, so some harmonics may easily be cancelled by the
     phase shift, each time different ones. Maybe even the fundamental. 

     Now make an experiment: Detune one of the 2 sources slightly. All kinds of phase
     cancelations will occur, and you will hear very strong timbre changes.

Re: MORF as built-in envelope calculator
Thursday, 05-Mar-98 10:25:20 

     130.67.2.216 writes:

     It seems to me that the MORF time scale is a "real" time scale, and that it DOES
     solve the rate/time conversion problem. To the extent that I have been able
     to test it, the rates are set so that the implicit "time load" of changing levels
     is taken into account. In fact, if you let one harmonic have the same value from one
     time slice to the next, it will even take care to set the corresponding levels in
     the HLE to two different values in order to avoid the skipping of stages that
     occurs when subsequent levels have the same value.

     But there appear to be some bugs in the MORF function. In particular, the Harmonics
     Levels of the MORFing source are sometimes set correctly, sometimes
     not. This will be corrected in the next version of the OS, I am sure...

     And it's a hassle that you have to save the sources before you execute the MORF.
     I wish the K5000 would read the sources being edited rather than the old
     version in flash memory.

     At least, the rate/time thing seems to be handled satisfactorily by the MORF function.

     The Formant Filter is transposed together with the played note if you play
