Title: sounds changing while played
Post by: levib2008 on July 25, 2016, 12:58:47 PM

Hi

I've created some analog sounds on Tempest and made the following:

1. Wave reset - 1&2
2. all Velocity amounts on each of the amplitudes is zero
3. turned on the FIXED LEVEL button
4. assigned the sound to a voice

and still, each time I hit the pad, the sound change a bit with the filter.

anything I'm missing?

thank you

Levi

I'm not an expert here but I'd say that the electrical components have different initial state when the sound starts (temperature, ...) so you get a different result. If I can read "change a bit" as change by a little amount, I'd think that this is what everybody expects from an analogue synths right? And this is what makes it alive. But if the sound is very different, then I don't know... :)

delaying the envelopes, like 1, some times helps to make a more consistent sound.
also, check the lfos are not freerunning.

One of the first things I noticed about T: when making a tuned filter sound, each voice's filter will differ by several cents. Recalibration never fixed this for me.

If you want a sound to be consistent, assign it to a voice. A sacrifice of polyphony for uniformity.

   •   How to avoid inconsistency on sounds by Yorgos Arabatzis:
1) Use Wave Reset
2) Mess around with various combinations on Delay parameters for Pitch,Filter,VCA or Aux envelopes.A setting of 1 will do the trick.Also play around with VCA attack time.
4) Using the self oscillating filter is unstable as Chris stated unless sound assigned to a voice.Try to use the waveforms of OSCs 1-4 instead if you don't assign a sound to a voice.
5) Assigning a sound to a voice can help also but produces a small click to the sound.
6) Take it easy on the Feedback.Settings beyond 80 create unstable environment.
7) Every tiny change you make in Tempest's envelopes counts so it's a mater of sweet spot in them.A spectrum analyzer can indicate these changes.
