PianoToLife 9.0.2

PianoToLife 9.0.2 — SympResHost has a new name (free, macOS / Windows, AU / VST3 / Standalone)

Hi everyone,

Some of you know SympResHost, the free host that adds a physically modelled sympathetic resonance around your favourite piano plug-in. Thanks to your feedback, it has grown a lot over the last weeks, and the name no longer said what it does. So from version 9.0.2, it is called PianoToLife.

Why a new name?
It started as a sympathetic resonance engine. Today it handles the whole life of the strings around your piano:

• Sympathetic resonance and sustain as one engine: a held key frees one string, the pedal frees them all, exactly like the dampers of a real grand.
• Real half-pedalling, with damping that follows your foot continuously.
• Pedal catch when you re-pedal just after releasing the keys, and now a natural bloom when you press the pedal on notes you are still holding (syncopated pedalling), with its own Held control.
• A natural string release, a wooden key and pedal action, Damper Noise, Ambience…
• All of it driven by the real sound of the piano you host, and calibrated for each instrument.

"PianoToLife" simply says what it is for: bringing your virtual piano to life.

Nothing changes for you

• Same plug-in identity: your sessions and presets open exactly as before.
• The installers replace the old SympResHost files automatically.
• It is still free.

What's new in 9.0.2

• Pedal on held notes: the resonance now blooms in about a second, a little less the later the pedal comes, richer on chords.
• Half pedal, re-pedalling and pedal catch fine-tuned against a modelled concert grand.
• Repeated notes under the pedal (Host Sustain): a restruck note replaces its previous strike, so repeats and diminuendos follow what you play.
• Upright key noise, interface themes, better defaults, smoother CPU.

A big thank you to everyone who tested, reported bugs and shared their ears on the previous threads. Your feedback shaped most of what is in this version. Comments, questions and audio examples are very welcome here.

The UI is very screen reader unfriendly. This sounds like a nice idea, but the inaccessible interface isn't giving me the drive to put it into my template. However, I'd be interested in a demo and I'd be interested to hear what this software has to contribute to the playing experience.

David Lai

So far, most of my time has gone into the audio side. It's a substantial modelling effort: sympathetic resonance, damper and release behaviour, pedal transitions, and key and pedal mechanism noises, all calibrated against real recorded samples, note by note and gesture by gesture. I'm developing PianoToLife alone, as free software, so I have to choose my priorities carefully, and the sound came first. I'm sorry this means it isn't usable for you yet.

What it adds to the playing experience: PianoToLife hosts your sampled piano (VSL, Kontakt pianos, Ivory, etc.) and adds what samples alone can't do. It models the strings resonating with each other while the pedal is down, how the dampers fall back on the strings (including half-pedalling and re-pedalling), the natural release of each note, and the wooden mechanical noises of keys and pedal. The aim is for the piano to respond to the way you play, not just to which notes you play.

Hi OlivierW, there seems to be a bug when I play chords (combinations of low and high octaves) from C -> Dm -> G/E -> G/F.

pianotolife-bug-20261003.mp3

Could you or anyone shows some use case scenarios or a manual guide. What does it means it is a standalone?

Loading VST piano then loading this .vst3 or?
Any basic tutorial would be appreciated for a non‑pianists such as myself. For example can it be used with Pianoteq? Or does Pianoteq come with its own SympRes engine which has to be turned off?

What about branded VSTi pianos? Just a besic demo would be great.

Hi PASHKULI, you could try the readme page, which might be helpful. You can find it via the link below.

Ah, got it. Tomorrow will try it out. Although might not be able to get its functionality that much as a non‑pianist.

wow this is very interesting, but since i'm awfully busy these days i wanted to ask if this thing can solve a very specific problem of mine, the vsl bisendorfer imperial has been on my radar for almost two years now, back then when i tried it i thought it had no competition and i still do... but one thing bothered me a lot and that very thing stopped me from spending any money on it, the imperial has a bug and that is when you depress the sus pedal the lowest velocities/dynamics disappear and playing soft sounds like mp range and it doesn't go any lower, tried to get vsl people to fix it but they said "it's the piano itself" (haha yea), so i'm interested if this can turn the sustain-down samples off and generate the sustain-down effect on its own, if that's the case then i'd be happy af to get it.

one more question though, can i use this as a plugin inside my daw or what? if the former is correct then how? as an effect in the mixer or as an instrument that recieves midi data?

pianow the imperial has a bug and that is when you depress the sus pedal the lowest velocities/dynamics disappear and playing soft sounds like mp range and it doesn't go any lower

I think I know what you mean in the VSL Bosendorfer Imperial. Using pedal pass through in the PianoToLife app indeed makes it difficult to achieve a low velocity range as the sound becomes louder as you press the pedal down. However, switching to the “host pedal” in the app keeps the volume consistent even when I press the pedal down.

pianow so i'm interested if this can turn the sustain-down samples off and generate the sustain-down effect on its own

I also notice that the Sus and Sost controls are disabled inside VSL Synchron Piano when I use the “host pedal” option. This likely disables the sustain-down samples, but subject to confirmation by Olivier.

However, I am using pass through pedal at the moment with my N1X as I noticed a bug that I reported above.

pianow can i use this as a plugin inside my daw or what?

It works as an instrument in Ableton Live, but it also loads the VST plugin with it.

jenpal i will fix this quickly

Hi erW,

Thank you very much for the report and the recording, it was exactly what I needed.

I found the cause. When you change chords with the pedal (C → Dm → G/E → G/F), PianoToLife takes over the previous bass notes with its own strings, using partials measured from your piano's sound. A new chord struck right next to one of those partials could leak into that measurement: in your recording, the B and G of the G/E chord made two high harmonics of the D in the bass much too loud. They then rang as two pure tones "between the notes", which is the strange extra note you heard. It could happen more or less at random, depending on the chords.

The fix is done and is being tested. It will be in PianoToLife 9.0.4, together with some interface polishing. I'll post here as soon as it's out.

Thanks again for helping make it better!

Olivier

many thanks , fixed in 9.0.4

Hi JenPal,

PianoToLife 9.0.4 is out, with the fix for the stray note you reported:
https://github.com/owfrappier/PianoToLife/releases/tag/v9.0.4

Your recording made it easy to track down. When you changed chords with the pedal down (Dm → G/E), PianoToLife misread the new chord as part of the previous one. It then kept playing two harmonics of the D in the bass (around C5 and G#5, a quarter-tone off) as if they were real strings. It was an old weakness in how PianoToLife measures each string. It became audible from 8.2.12 onwards, when the half-pedal and caught strings started playing much closer to full level. That's why 8.2.8 didn't have it.

Since the fix, chord changes are clean on my side. Repeated notes also sound more in tune, and CPU use dropped a bit too.

Could you try your C → Dm → G/E → G/F passage again and tell me if it's gone? If you still hear something, please send me:

• a MIDI file of the passage;
• your pedal mode;
• which piano you're hosting.

Thanks again for the report, it was an important one!

Olivier

pianow Hi PianoNow,

Yes, that is exactly what PianoToLife is made for. With VSL pianos you need to use the Host Sustain pedal mode (the default):

• In Host Sustain, PianoToLife never sends the sustain pedal (CC64) to the VSL piano. The Imperial only ever plays its pedal-up samples, so you keep their full dynamic range, down to the softest layers. The sustain-down samples, and the bug you describe, are simply never used.
• PianoToLife itself holds the notes while the pedal is down and generates the whole sustain effect: the strings freed by the dampers ringing in sympathy, half-pedalling, re-pedalling, the dampers coming back down, all driven by the real sound of the Imperial.
• That is also why the VSL pianos need this mode: on their own, they only switch between pedal-up and sustain-down samples, with no transitions between pedal states. Host Sustain bypasses the pedal completely between your DAW and VSL, and PianoToLife takes over the transitions.

How to use it in your DAW: PianoToLife is an instrument plug-in (AU / VST3, or a standalone app), not an effect.

1. Create an instrument track and insert PianoToLife as the instrument. It receives your MIDI as usual.
2. Inside PianoToLife, scan your plug-ins and load VSL Synchron Bösendorfer Imperial in it.
3. Keep the pedal mode on Host Sustain and play.

For the best result, run the automatic capture once with the Imperial (about 35 minutes): PianoToLife plays every note and builds a resonance model of that exact piano.

It's free, for macOS 14+ (Apple Silicon) and Windows 10/11:

Have fun, and tell me how it goes with the Imperial!

OlivierW Your recording made it easy to track down

OlivierW Could you try your C → Dm → G/E → G/F passage again and tell me if it's gone?

Thanks, Olivier. I’m glad my report and recording helped. All is working perfectly now. 🙂

I also tested my VSL Fazioli and captured its own SR. 🙂

PianoToLife 9.1 is coming soon, with a more beautiful interface… and something hiding inside the piano.
Open the drawer and you'll see. 🙂

9.1.2 is out

https://github.com/owfrappier/PianoToLife

new interface :

Windows Narrator / NVDA and macOS VoiceOver: every control has a spoken name and help, Tab follows a logical order, and sliders can be moved from the keyboard.

Thanks for the update, OlivierW. I love the new look and the damper mechanics, which help visualise half-pedalling. 😍

I’ve been playing a few of my Native Instruments now since the added sympathetic resonance, which makes them sound richer. I’ve already added and captured the individual resonance of my Noire, Grandeur, and Claire, plus more instruments to come.

PianoToLife is now my go-to app for loading my VSTs. Since I have many VSTs, it makes switching much easier and quicker. However, I prefer not to have the pop-up of the VST window and the prompt asking to load presets when changing a preset (and I just wait for few seconds to allow the VST to fully load). 🙂

jenpal Thank you so much, jenpal! It's great to hear PianoToLife is now your launcher for your NI pianos, and that Noire, Grandeur and Claire are calibrated.

I use it myself with these Kontakt pianos. Their built-in sympathetic resonance can't bridge the sustain and the resonance between keys, because the two are treated as separate phenomena, in layers that sometimes contradict each other. In a real piano, everything is interaction: the strings, the dampers, the pedal and the soundboard all work together. PianoToLife models them as one system. That's why it brings back the life of many high-quality sampled pianos whose resonance scripts sound too artificial.

Good point about the window pop-up and the preset prompt when switching quickly. In the next version, both will be options you can switch off, and the setting will be remembered.

Thanks for the feedback!

OlivierW Just wanted to say, I've been playing around with your resonance plugin for the past day or so and I'm super impressed by what you've managed to accomplish here. To be honest, I wasn't expecting much when I first downloaded it, but the whole thing actually works way better than I was expecting. The overall operation is incredibly smooth, and I'm really enjoying trying it out on various piano VSTs. So far I've done captures all of my VSL pianos as the Korg SGX2 and a few Kontakt pianos, and everything has worked flawlessly so far.

I'm also really impressed by how quickly you are issuing updates - it seems like every time I check, there have already been 3 new versions released. 😆

Anyway, many thanks for sharing this project with everyone. You are clearly very passionate about it, and have managed to channel this passion into something that I believe is genuinely unique and useful for the larger community.

Keep up the good work! 👏

OlivierW

idk how to thank you man, these problems with vsl pianos has make them unusable for me since i discovered them, and since the imperial is my all time favorite piano vi i was heart broken the moment i noticed this issue (it rendered my go-to piano completely useless) now you've changed that and i am personally grateful,

it's actually crazy how a single man can produce such an amazing piece of software (and it's free)

and it's even crazier that the actual developers of the synchron imperial basically didn't give a shit about their stuff even though they have the money, time and the resposability to fix such stuff especially when users point them out, again thanks a million times man, keep up the amazing work😊
