GVST pitch-correction and guitar-synth betas

[nomidi]

just tried your tuner and it sounds quite nice

Good one !

well, nice for my purposes (Cher style effect) and nice compared to other free ones. Very promising imho.

Just tried Gsnap. I appreciate it's beta, but it has a long way to go. Very glitchy on vocals. There is a big need for a good freebie pitch corrector - best of luck.

I don't agree! I believe ( ) it's aimed at the "Cher effect"

I've been using gtune for a while - simple and efficient, so pretty much a default choice when tuning anything. Haven't got around to trying out gsnap yet, but I like your plugins a lot.

Thanks everyone.

There will be an update to GTune/GTuneXL allowing the selection of tuning references other than 440Hz, probably this evening.

As for GSnap, it is definitely more useful as a Cher effect - I doubt you could get a natural result using it on a whole vocal, although I have successfully tamed a few bad notes during comping.

Cheers.

You're on my (ever increasing) donation list, anyway. I'm recently lingering in the absence of a job, so it may be a little while.

That tuner is fantastic man, i havnt found a VST tuner thats that responsive yet. Excellent work man thanks alot.

[JackDark]

I always look forward to anything by GVST! Can't wait to try this stuff out, thanks!

Thanks everyone.

There's a GTune update - See the 'Gtuner- Please make a larger version' topic.

thank you so much G for fixing your G plugs... ive always crashed T1/T2 with Ghi and Glow, ...

also i think it'd be fun to put some gradients on your knobs, it might look kind of neat... but i do like the minimal approach.

I have added GTune to the GVST website, which is a simple chromatic tuner. Off the back of that, I am working on a guitar-driven synth, GSinthG, and a pitch corrector, GSnap. These are in 'beta' at the moment, which just means that they're not finished. I would be interested in hearing from anyone who cares to try them out.

I checked out GSnap, and when activated it caused a DC offset larger than my speakers/soundcard could handle.

The result was a loud pop, and then basically quiet, random noise. No audio was really heard (probably becaues the DC offset pushed the alternating voltage beyond the range of the speakers).

I tested it using Plogue Bidule, on a Windows XP Pro Machine. I used my internal soundcard.

Hi Moseph,
I just downloaded Plogue Bidule and could not reproduce what you describe. I used a wave player to play a vocal sample through GSnap and it sounded just as expected. If you can give me more details then I will try to reproduce and fix the problem.

Graham,

I REALLY like the GVST stuff. Thanks so much for sharing it. Particularly GTune and GSnap, but some of the other ones will come in handy, too!

Thanks again!

Hi Moseph,
I just downloaded Plogue Bidule and could not reproduce what you describe. I used a wave player to play a vocal sample through GSnap and it sounded just as expected. If you can give me more details then I will try to reproduce and fix the problem.

Those really are all the details. The soundcard is the built-in Soundblaster compatible that Dell puts into their Machines (it's a Dimension Desktop circa 2002).

I use the latest beta version of Bidule (because you have to, basically), and I set it up in exactly the same way I think. It looked like this:

|vocal track (mono)| --> |GSnap| --> |Bidule's mixer| --> |Output waver|

To my knowledge, I'm using Wuschell's ASIO4All drivers with Bidule. There's the slight chance I'm actually using the MME device drivers installed with Windows XP Pro (possibly a more recent version since 2002, but I can't remember).

I'm not at home right now, but I'll check it out on other systems and see if I have the same problem.

Dig the rest of your stuff though. I'm excited to try to get this to work, it'll be handy.

Gsnap only causes the error when I use the right output channel.

This happens regardless of what I put through the GSnap bidule, it only causes the error on the right side.

Also, what exactly do the parameters do? I've been playing with them by likening them to an Antares ATR-1 (which I have some familiarity with) but I can't get really dramatic effects even if, for instance, I run audio through it and set it to the wrong key (say, C# Major). That's a little counter-intuitive to me.

[gy]

Ah. Well, the problem there is that GSnap doesn't have a right output channel. It's strictly mono - one-in, one out. Your host must be assuming that there is a right output, which would result in it playing an unitialized buffer, which would sound exactly as you described.

So, my advice is don't use the right output, 'cos there isn't one really. Future versions will be stereo-enabled.

Parameters:
Min Freq - Lowest frequency that will be detected
Max Freq - Highest frequency that will be detected
Gate - Minimum peak level required for detection
Speed - Lower numbers allow faster pitch-detection at the cost of increased chance of error
CorrAmt - The amount of correction
CorrAttk - How long it takes to go from bum-note to corrected-note
CorrRel - How long it takes to return to normal after the bum-note has finished
Key - Dictates the notes that are snapped to

The key selector will be replaced by free note selection in due course.

Hope that helps.
