as far as i know, there isn't one. and i'd imagine it would be really tough, if not impossible, to make a sound that really sounds like a grand piano.

that said, if you do end up finding one, let me know! :D

Haha. Ok will do!
Yeah i find it annoying that a keyboard can come without a Piano sound. I know there's an E.Piano but thats not quite the same! The only way i can get a grand piano sound at the moment is using the Garageband program on my Macbook and using the R3 as a controller. Oh well i guess that might have to do!

The Radias/R3 is not a ROMpler or sampler workstation!

It's a mathematical synth, generating waveforms by calculations of algorithms on the fly. It does not use extensive samples of acoustic instruments.

That's not to say you can't approximate (or "fake") a synthetic grand piano sound in some way, though.

Try using the comb filter...

Here's what i did:

http://www.robotgigante.cl/audio/radiaspiano.mp3

It works great on the top octaves, but it sounds like an electric piano in the lower. Perhaps if i add a second layer for the lower it might sound better.

The secret formula:

Osc 1: ramp
Osc 2: Square
SYNC: on
Add a little Noise.
Add a little drive.
Attack: very short.
Decay: very short
Sustain: patched to the mod wheel. So i can play with it.
Release: intermediate.

Filters: Two serial filters. The first one is an LP18, put there to reduce the brilliance of the sound and add some resonance. The second one is the comb filter, which adds some plucking. Add carefully resonance with this one to avoid a phasing sound.

Patch 1 connects a sinewave lfo+1 to the pitch.
Patch 2 connects M.Wheel to the sustain.
Patch 3 connects the Envelope Generator #3 to the noise generator, in order to add that hammering sound in the higher keys.
Patch 4 connects Keytrack +62 to Patch 3 (noise sounds brighter on the higher keys).

The cherry on the top is reverb effect, added tastefully.

R3 Grand Piano

Post by TecRoc »

Hello, bezmond

Without multisampling it is very difficult, if not impossible to have an accurate
emulation of a Grand Piano, imo. Another synthesis approach would be
physical modelling:

Although not the real thing, I have designed some piano-like patches for the R3,
that you might find useful:

but if you need the "real" sound you should check out those multisampled
GP packages.

Nemmo, that sample sounds really good. I've tried to reproduce it with the parameters that you've given me, but it still sounds so inorganic and digital. Are there any other noteworthy changes or parameter settings you can share?

There is an inherent limitation of a VA synth to emulate an acoustic instrument with several hundred real strings, in a metal frame, inside wood, with padded hammers, dampers, soundboard, played by real fingers on a stage, in a studio, or in a concert hall, that costs 100 times or more than what you paid.

The closest approximation is to record all of the notes of a real one at various velocities under carefully controlled conditions. That means using a ROMpler or Sampler with several hundred samples, or a more sophisticated physical model that starts with a better approximation of the natural acoustics, instead of the overly simplistic OSC>Filter>Amp>Effects model of VA synthesis that mostly hasn't fundamentally changed in the last 50 years.

Metal strings hit by a hammer are not merely simple wave oscillators. There's a lot more going on in a real Grand Piano than that. When you hit one open note on a piano, nearly all the strings will vibrate due to harmonic resonance shared with it, some more than others depending.

I forgot that Unison was on, two voices, +15 pitch difference.

If i could get the Editor working i'd send you the patch.... (but i have tried every possible method and i can't get my Radias and my computer talking to each other !)

I've gotten closer, but it sounds more like a clavinet/e-piano mix now. Anything special I need to do to the oscillators? Tuning for OSC2 or control tweaks for OSC1?
