Gotta say, I wasn't that impressed with this one. Of course it's free, so the value for the price is excellent. Kudos to Sound Magic for giving it away, and I hope it's brought some customers to their full products. But - I find the sound quality pretty strange - so I'll talk about it from that standpoint.

Like others have said, the release sound is unrealistic - there's an optional "REL VOL" setting that actually plays a different sample upon release of a note, a sort of higher pitch flutey squeak, which when you boost it to the point that it's audible sounds really strange to me. When I first heard the plugin I thought something was wrong with my system. If you turn that off by setting reduce "REL VOL" to 0, the notes still sound strange when they end - the volume cuts off very abruptly. You can set "RELEASE" to be longer, which controls the volume envelope, but you lose expression and control of when the notes stop - and still it tapers off unrealistically. Even when you don't release the keys, the notes don't sustain very long - e.g. if you play a chord and hold it, after about 6 seconds the notes will all abruptly end at different times. It's like the volume envelope just abruptly jumps to zero once it's below a certain threshold.

Aside from that, the actual sustained body of the notes sound warbly - it's not a smooth note, there's some pulsation and a bit of a bubbling effect, maybe from compression in the samples, or noise reduction on the original recordings - not sure.

So overall, when it's dry, the sound comes off really strange to me. You can bury that in reverb to cover it up, but to me that's just sort of sweeping the sonic problems under the rug.

Aside from sound quality, the UI is a little plain. I had a lot of bugs and display glitches with the 64-bit version. The 32-bit one functioned correctly though (this was using FL Studio 10).

This plugin is the "Zebralette" of the piano market. When companies produce these cut down freebie versions of their products we all win. The company gets goodwill and familiarity with it's products, and we get free stuff!

I've been using Piano One for all my practicing, improv and composition needs for the best part of a year, and the sound is on the whole very satisfying. Now, you can practice and do bare-bones composition on polysynth sounds, but for some reason, you just can't beat the experience of sitting at a piano when it comes to teasing ideas out of your subconscious.

This piano is even good enough to be used on professional tracks semi-naked, with one caveat - the release - as has been pointed out in the other review, is pretty unrealistic. You can fix it a bit by dragging up the release slider, giving a more realistic release length, but the *shape* is still wrong. Mostly you can fix this with reverb (using the reverb that comes in the plugin or an external one), but still, it's the fly in the ointment of an otherwise near-perfect freebie, and the reason I'm giving 9 instead of 10.

The look of the plugin is pretty janky, but the interface has some good controls (velocity curves for example, very useful for extracting different piano styles from your playing). Their paid plugins have much nicer atmospheres to them and it seems fair that they'd cut back on this a bit in the free version.

I'll definitely be checking out their other piano products with the hopes of buying them if they can build on the quality of this one.

One of the best free pianos around, probably better than many commercial piano plugins or sample libraries.

Sound - it has an excellent open and clear sound. Many modeled pianos miss a certain "brilliance" of the sound as well as some sampled pianos (probably recorded with darker microphones). This one sound like a real good piano, how you would hear it from near (while playing on a real piano).

Interface - a simple interface with very self explanatory controls. You can tweak the sound, add some impulse based reverb, open/ close the lid, control dynamic response (velocity curve), etc...

CPU and RAM usage - as mentioned by developer, low usage of both. Can run on slower or older computers without chocking your projects.

On the downside:

- the release is a little unrealistic and can be a turn off for people who are used to play real pianos. You can fix it a little with the release slider, but not make it good. In a project you can hide the problem by using the sustain pedal. Still, if you care more about the sound than response, this is the free piano you'll ever need.

- interface could use a more inspiring design/ colors/ better knobs and sliders graphics.

Very good review, I've used it on a couple projects and agree with every point made.

6 June 2012 at 4:47pmzincalloy

I can't use the presets neither in Version 1.1 nor 1.2.

What is the prob?

If i try to load them in Cantabile or my Daw I got this Message:

The following error(s) had occured: VST PLugin-Piano One-Failed to load preset - version mismatch.

Who'd like to help - love and need this plug

You need to download Version 1.3 and Presets for 1.3 to solve this issue

7 May 2013 at 6:21pmMusicMonster007

Do the notes always cut off after about 10 seconds or do I maybe have an old version? I downloaded version 1.3, installed it, then downloaded the patch for v1.32 and substituted the .dll file - is that all I need to do?

Thanks for any help.

22 July 2012 at 4:18pmlstone92

Everytime I try and use this VST it says cannot find any instruments. Help me? :)

23 July 2012 at 3:02pmshane1980

It would be better that you can contact our customer service about your issue :)

27 July 2012 at 2:55amwillard

I downloaded a version that says 1.3 but it will not load the presets on this page.

what I downloaded was from the supreme piano one page http://www.supremepiano.com/product/piano1.html

the file was PianoOne13zip

It works with the default instrument, but I'd like to try the others

27 July 2012 at 5:18pmLAGinz

I think at one point, right after 1.3 came out, there was either a problem with it or the download was actually 1.2., even though it was labelled 1.3---I had the same preset problem. The 1.3 version on the site now though is definitely 1.3 and works for me with all of the presets. I use the 32 bit version bridged in my 64 bit DAW, since for some reason the native 64 bit version (especially on the release) sounds kind of odd.

That being said, this a really good sounding piano --especially for free!! Props to the Dev.!

When I download PianoOne13.zip for win32, the file properties says the version is ?! I've sent email to customer service but no response for several days. = /
27 July 2012 at 5:59pmwillard

Mine says the same. A real bummer

27 July 2012 at 5:30pmLAGinz

Hmm...I assumed that once they got the right 1.3 up there it stayed up there....but maybe not :(

27 July 2012 at 6:01pmwillard

Is there another download connection? Maybe that would have the correct version?

27 July 2012 at 6:22pmLAGinz

OK, I just re-checked the labelling on the actual dll file currently in my VST folder (Windows 32 bit version). It also says even though the zip said 1.3. BUT....all the presets load and are working properly for me in Studio One Prof. 2.0.6.

27 July 2012 at 10:01pmwillard

When I load the presets downloaded at:http://www.kvraudio.com/product/piano-one-by-sound-magic/downloads, I get the error "mismatched version"

I also downloaded the new Piano One Version 1.32 Patch - Upgrade Only there.

I'm using Cantabile 2.0

3 September 2012 at 3:57pmchopin4525

I guess it's a Cantabile issue because when I used Piano One in Sonar it worked flawlessly and loaded presets without any issue.

27 July 2012 at 10:15pmLAGinz

If my recollection is right, I think the only preset bank that won't work would be the original "kvrer" one, which was superceded by a newer one on that same page. All the rest of the preset banks should work.

I downloaded all the different Piano sets from KVR here but they don't show in Piano one, version 1,32. I got FXP files from the sets, inserted them in Piano One's Folder, but they do not show as presets in the VSTi, only the Default, which sounds awesomely Great, thank you, and a few included numbered Patches that deliver a strange volume boost noise when I play them (Ok, maybe because it's a demo) that I could silence by moving the Attack slider each time but I see no changes in the parameters and the sound is the same as the Default.

I'm using Acoustica Mixcraft Pro Studio 6 as my DAW and all my VSTis 32 bits load and play perfectly.

My PC is: Intel i7, 870 on Windows 7 64 bits, with 6GB DDR3 RAM.

Am I doing something wrong? Is there a way to install them so that they show and load in Piano One? A special folder (re-) naming, a specific location where to put them?

Thank you so much for any help and for such a great product!

21 August 2012 at 4:15pmshane1980

You have to manually add each preset into the patch #. The Preset always
appears as fxp file which you have to use load instruments option (maybe
it has another name in other DAW)to load them. It will not automatically recognized by the plugin

22 August 2012 at 4:01ammusicfoly

Thanks for answering shane1980 but how can I do that?

Acoustica Mixcraft pro 6 doesn't load fxp files, only fxb and I cannot see the presets in PianoOne as I try to load them, only the default 1 and 2 (apart from the Patches).

I don't know how to manually add each preset into a patch.. Sorry for my ignorance..

23 August 2012 at 7:28amalex_sobolan


I've downloaded piano one too but i don't know how to install it.

Do you know how or where i can find some instructions?



25 August 2012 at 1:32pmmusicfoly

Alex, do you have a VST folder? Yes? The whole PianoOne13 folder has to be copied or moved into that VST folder. I don't know what DAW you use (I use Mixcraft 6, I created mine) but I believe every DAW has a VST plugins Folder, be it installed by default by the program or one that you already created.

Sorry cannot help you with the other DAWs. Help should be on its way soon...

2 September 2012 at 2:00amHooj

This is EXACTLY what happened to me when I first added the patches. So I opened "Piano one" inside my DAW and manually assigned the patches (I downloaded) to the numbered (empty) patch banks under the "presets" drop down menu.



25 August 2012 at 11:18amNickl

I have downloaded Piano One and installed it in my VST folder. I have tried using it in a couple of different DAWs but can't get any sound. In both cases I can see the keyboard keys move in response to the events sequence but the sound is completely dead. I haven't had this issue with the various other VST instruments I use and I can't work out what I am doing wrong with Piano One.

Can anyone help please?


25 August 2012 at 1:15pmmusicfoly

Try both versions (32 and 64 bits, not together though). Sorry, can't remember which one I installed but it plays beautifully in Mixcraft Pro Studio 6.

I guess you installed the whole folder (PianoOne13) in your VST folder, not only the dll.


25 August 2012 at 1:31pmNickl

I'm still in the world of 32bit but your point about the location of the whole folder may be the problem - I can't remember whether I put the whole folder in the VST folder or just the dll. I'll check it out when I get home later.


29 August 2012 at 9:54pmmusicfoly

You're welcome!

Anyway, if you're using Mixcraft, only 32 bits VSTs are usable. I have Windows 7 64bits, but I believe in the VST world, it works accordingly to your DAWs' capacity. Some can use 64 bits, some 32bits only. As for any other DAW, check in the "About ...." section or ask around..

Glad it helped you! :D

29 August 2012 at 2:48pmralphdewu

Hey there the update patch still appears to be version 1.0 so can't use the other presets

2 September 2012 at 6:24amKKram

Hi hope someone can assist with this issue. I have installed the Piano 1 component into library/audio/plugins/Components folder and run SPRuntime.

When I open Mainstage it reports that the plugin failed to load. When I select authenticate I get the following error message:

Carbon View Components Available: 1
auvw MSP2 Maze - ERROR: View Component specified, but can't be found "

Is there a way to fix this error?
