Vsynth, XT, GT Monophonic clicks

[Shambler]

Ok thanks, I'll find a plugin more like an oscilloscope display, I think Vox do one =)

[edit] actually all I have to do is record the audio in cubase and look at the audio file ^^

[Shambler]

This is interesting,

The audio ouput sits at 0, as you would expect.

When you play a note, instead of the positive half of the sine wave being generated straight away there is a negative pulse, just for a few millisecs and very small in amplitude.

The waveform then comes back up to 0 and the sine wave is generated, looks clean apart from this initial negative pulse which occurs every time a key is pressed even if another key is already sounding.

Not got time to post any pic's atm but I will try and upload some in the next couple of days.

I will also try recording a note and then editing this negative trough out of the waveform to see if it is the cause of the click, I can't see any other 'fault' with the sine wave.

Shambler, is the "Impact" parameter set to 0? Please make sure it is.

[Shambler]

Yes, Impact was on zero.

I am not sure what the impact waveform should look like until I test further but I wouldn't think it would look like this...I'll have to vary the parameter to see what it does.

I expect impact to start the waveform on the last 100-75% i.e. the last quarter of the sine wave.

Near 100% would be a small click, 75% would be a large click since it would start the waveform at the lowest negative point...supposition though until it can be checked.

This click waveform I see on the audio does not follow the sine wave curve.

Here's the findings,

All of the waveforms(including square) have just OSC1, no mix,no cosm,no tva and no FX.

Also I don't know what if anything my sound card is contributing to the signal behaviour.

Playing c4 and c5 in rapid succession, impact 0

Transition of c5 to c4




Holding down c4 and playing c5 repeatedly

Transition of c4 to c5




Make of it what you will but it looks like some higher than requested amplitudes and weirdness to me

[Shambler]

Square wave....square wave you must be kidding lol

You wouldn't think these were digitally generated waveforms.

Must say I still love my GT though even with its 'characteristics'

Transition c4 to c5,



And HQ square,

[Klangwelt]

The "shaky" edges of the square wave are normal and the result of the limited frequency range that you have in the digital domain; but I'm really surprised to see these sawtooth-fragments and the diagonal lines in the lower wave, wow ...

But in the end, it's these "anomalies" that result in the unique sound-characteristic of different instruments. If you should own a Fantom or any other "ROMpler", just have a look at all the different sawtooth- and square-sound-samples that are included in their respective sample-ROMs. They all sound a little different, but they were all intended to be "exact" synthesized waveforms. Viva la differenza!

This is why there are features like portamento and legato which would smooth out the transitions.

^Yes.
It's the nature of truly monophonic patches, especially sine bass to click at cutoff the same as if they were poorly edited.

Slight port/gliss/legato settings act as a sort of "immediate zero-cross envelope transition algorithm", without having to actually wait for the next zero-cross in the previous note, before sounding the new note.
Use them.
