I'm making 'Choir Boy' available to try out (Alpha test).

‘Choir Boy’ is a multi-voice pitch shifting plug-in. From a single input (mono or stereo), ‘Choir Boy’ generates 3 additional voices, which can be tailored to various pitches.



This boy is still a bit rough around the edges and I don't have any immediate plans to release this as a product, but you're all welcome to give it a try and kick it around.

'Choir Boy' can be downloaded directly from this link (no registration required):

Direct Download for Choir Boy

Try it on vocals, solo instruments and polyphonic instruments. No instructions I'm afraid.

The demo is good for 90 days and mutes the sound every 25 seconds.

Depending on feedback, I’ll consider how to proceed with development.

Cheers and Enjoy!

Just updated the demo - reduced latency of 'voice 0' and improved sound.

Cheers

Hi, always interesting to see new stuff from your hand - always original plugins

I was wondering if you´re thinking about planning midi control of the tones being shifted to, and also formant shifting?

In that case you´ve got a product there of which there, as far as I know, only exists two other kinds on the vst-market:

Akai (I think it´s decabuddy) and Steinberg Voice Machine.

Just ran it over some beats,,, sounds wicked,,and quality of sound too,,, you've done it again.

Hi Roman,

I've got a few in the pipeline based around the theme of pitch detection and shifting.

I would like to clean up 'Choir Boy' a lot more (the code can be optimized somewhat - but that needs some research on my part.) Adding formant shifting, or format control, will make voices sound a bit more realistic as they are shifted. I also need to do some research there - and may add that if it doesn't become too computationally expensive.

As for midi control, I have another prototype on the desk which I called 'Track Boy'. It detects pitch and converts to midi. The idea is to be able to extract bass and melody lines from non-midi audio tracks. As it happens, I just got it crudely working about 10 minutes ago (but still needs a lot more work before I can let it out).

Thanks for the positive feedback.

Ok, I look forward to see how well this well work. I think I´ve read that the few programs outthere capable of doing that translation from audio to midi thing aren´t so good, which is understandable, cause it may not be so easy, especially not if you´ve got more than just a solo voice.
But you know what I ment with midi controlling the pitch/formant, right?
I think this wouldn´t be a very complicated thing to make, once you´ve figured out the formant stuff, which nowadays seems not to be a big secret anymore - there are lotsa synths, also free ones - dealing with formant synthesis.
There´s been some tables or links to them posted here explaining something about formant frequencies. Not that I know anything about whether that´s easy to understand or not when it comes to programming, but thought you´d like to know if you don´t already

After taking a look at 'Decabuddy', I now know what you meant (very impressive stuff). Using midi to control the pitch of the individual parts.

In 'Choir Boy' at the moment, you could use automation to do that (though this would be fiddly). To add midi control wouldn't be conceptually so difficult, but is quite some work - thanks for the suggestion though.

As you spotted, the challenge on the pitch midi follower is to determine the correct frequencies in a mix - I am working on that, because that would be the added value of 'Track Boy'.

Combine the pitch-shifter with the pitch-detector, and make Autotune!

Forever,

I thought excactly the same, and that our man here then could add some new inventions so it´ll be more than just a simple autotune. He seems pretty good at that, like CloneBoy which was a very innovative plugin.
I could imagine that once you´ve managed to make an autotune plugin, if you´re a creative person, you´ll automatically see how much weird stuff can be done with the code you´ve got.
Kantos was a step forward, but I hated it for not being able to output the data extracted from the input to other plugins.

'Choir Boy' Just updated to V1.10. Further improved sound quality.

Same download link

I really dig this kind of stuff. Excellent stuff!

I'm just working on putting in the midi control for the pitch of each voice.

I'm almost there. Hope to have a demo update, including midi control, soon.

Great! After thinking a bit, I´ve come to the conclusion that there are no polyphonic keyboard controlled pitchshifters (in vst format) without formants being controlled as well - untill now!
Am I right?
Personally I prefer the formant stuff because my music is not of a kind that would allow a mixed choir of mice and bears - though of course it can be used on drumloops and such as well - but I´m sure there are people who´d love an original touch of a more extreme character to their sound, provided by your keyboard controlled pitch shifter once it´s finished.
Looking forward to play around with the demo when it´s reached that point!

very nice.. I like this a lot

works well on other instruments too
got some really nice fx out of it already


is there a version without the volume gaps for registered elevayta users?

I'm happy you like it already. FX on non-vocal was what I also had in mind.

I'll see how it turns out. At the moment, I'm up to my neck in 'Space Boy' ... Spaceman.

Please!!! I really want an autotune type thing for cheap...

Any news on development?

Greg

He's been on vacation abroad the last few weeks. I think he got back in town a couple of days ago, so maybe not much longer now.

Yawp, I purchased Space Boy as soon as Paul got back.

Greg

I'm just getting my programming steam up again.

'Choir Boy' is nearly there - but then I had some more ideas while I was away. I have a few more in the pipe and I'm still working on how to realize them.

'Space Boy' seems to have taken off big time - this has also distracted me.

However, 'Choir Boy' is my first priority. The MIDI is working, but not yet to my satisfaction.

I know you're putting midi in, but i also noticed at one point you were thinking more of fx for rythms.
my 2c.
when you have midi controled worked out and if you have high quality formant shift as an OPTION then you will have quite a niche market. make sure the pitch quality for vocals is good. it is very important for many of us here. steinberg's voice machine was very synthetic and no longer available, and decabuddy is just too damn expensive atm and also discontinued anyway i believe. going by your other prices i would guess that this will be affordable. people will go for it i'm absolutely sure. i for one am dying for a higher quality voice machine decabuddy type thingy.

any news on this beauty? still tbd.
