Using Radical Piano

Loading and saving patches

Loading and saving patches is done in the same way as with any other internal Reason device, see “Loading patches” and “Saving patches” for details.

Selecting piano sound sets

A patch in Radical Piano can consist of a mix between two piano sound sets. The mix could be between two sound sets from the same piano, or from different pianos. You could, for example, blend a Close mic’ed upright piano with the Floor microphones from a grand piano to create your own custom piano sound. The piano sound sets can be selected in the Piano Select section:

The Piano Select section.

1.	Select desired piano sound set(s) by clicking the corresponding LED button(s).

You can select one sound set to the left of the Blend knob and one to the right.

2.	Set the mix between the sound sets with the Blend Microphones knob.

If you only want to use a single sound set for your sound, set the Microphone Blend knob to min or max.

Character

Set the character of the sound with the Character knob.

Range: Subdued to Agitated, in 24 steps, with natural sound at the 12 o’clock position.
Subdued produces a warm and mellow tone whereas Agitated generates a brighter and significantly more pronounced tone.

Changing the Character value temporarily mutes the audio outputs.

Volume

The master volume control for Radical Piano.

Velocity Response

Most sample-based piano instruments and sound libraries on the market use a predefined number of velocity layers. Depending on how soft or hard you play the keys, samples from a specific velocity layer play back. Due to memory limitations, the number of velocity layers aren’t often that many. This can make the velocity response feel and sound unnatural. Thanks to the combination of samples and physical modeling in Radical Piano, all sound sets feature very wide and completely seamless velocity ranges.

With the Velocity Response knobs you can tailor the dynamic response of your piano sound.

•	With the High knob you set the timbre for the highest velocity.

Note that the High parameter can go far beyond the natural range of an acoustic piano, which is great for experimental sounds.

•	With the Low knob you set the timbre for the lowest velocity.

With the Low knob set to zero (marked with an ‘S’) playing really soft won’t play back any sound at all. This can be useful if you, for example, want to hold down a chord and then play other keys to introduce the sympathetic resonance effect, see “Resonance”.

•	With the Curve knob you set the shape of the velocity curve - from exponential, via linear to logarithmic.

Set this parameter where it feels the best to play. There is no “perfect” position since most MIDI keyboards respond differently to velocity.

If you want a natural dynamic range, set the Low knob to around the 9 o’clock position and the High knob to around the 12 o’clock position. Adjust the Curve setting to your liking.

If you want a dynamic range that stretches beyond the range of an acoustic piano, set the Low knob to zero and the High knob past the 12 o’clock position.

If you want a static response (with the same timbre no matter how soft or hard you play), set the Low knob to max and the High knob to zero. Note that there will still be some velocity sensitivity left for controlling the volume.

Tune

Cent

Set the overall master tune of your sound with the Cent knob.

Range: +/-1 semitone (+/-100 cents).

Drift

The Drift parameter can be used for introducing a slow irregular pitch variation to your sound. It’s perfect for adding kind of a “scary” or melancholic touch to your piano sound.

Sustain

The Sustain parameter is a special feature in Radical Piano. It lets you control the piano sustain continuously from pedal up to pedal down. As on acoustic pianos, the sustain pedal is not either “on” or “off - it can be “somewhere in between” as well. The Sustain function in Radical Piano simulates this behavior.

The Sustain parameter can be controlled either from the Pedal LED strip control on the front panel or from a Sustain pedal connected to the Sustain Pedal input of your MIDI master keyboard.

•	When you use a standard (switch type) sustain pedal connected to a standard sustain pedal input on your MIDI keyboard, this will control the Sustain function in Radical Piano as either Off (‘0’) or On (‘127’).

You could record using the standard sustain pedal and then manually edit the Sustain Pedal performance controller data in the note clip in Reason afterwards and adjust the “in between” Sustain levels.

The Sustain parameter value (and LED bar) will always adjust to the latest incoming Sustain Pedal data, be it from the Pedal LED strip control or from a sustain pedal connected to your MIDI keyboard.

Resonance

Sympathetic resonance is a physical phenomenon that can occur in acoustic instruments, like in pianos for example. It means that any undamped strings will ring along with the played strings. For example, if you play a key with the sustain pedal down, all other strings in the piano will also vibrate at various intensities. Similarly, if you hold down a number of keys (so that the dampers are off the strings) and then play additional keys, the strings for the held keys will resonate.

With the Resonance controls you set the amount of sympathetic resonance in your piano sound.

Level

Set the amount of overall sympathetic resonance in your sound.

Release Time

Set the time it should take for the sympathetic resonance to fade to silence.

Envelope

Radical Piano features a special type of envelope generator which is used for shaping the character of the piano sound.

Attack

Set the attack time for the piano sound, from immediate to (unnaturally) slow.

The range is 0-200 ms.

Decay Curve

Set the shape of the decay curve.

This control determines how the sound should decay when you play and hold the keys.
The range is from exponential, via linear, to logarithmic. Exponential settings will make the sound decay faster, which simulates a piano with little body sustain. Logarithmic settings makes the sound sustain more slowly and simulates a piano with a lot of body sustain.

Release

Set the time it should take for the sound to fade to silence once you release the keys.

This simulates the behavior of the dampers. For example, worn out dampers could result in somewhat longer release times.

Mechanics

The Mechanics section features controls for the mechanical noise.

Key Down

•	Key Down controls the level - and character - of the noise that occurs when the keys are pressed/hit.

At the 12 o’clock position the noise is the most natural. Above the 12 o’clock position the noise is more pronounced and below the 12 o’clock position the noise is suppressed.

Key Up

•	Key Up controls the level of the noise that occurs when the keys are released and the hammers and dampers return to their initial positions.

At the 12 o’clock position the noise level is natural. Above the 12 o’clock position the noise is louder and below the 12 o’clock position the noise is quieter.

Pedal

•	Pedal controls the level of the noise that occurs when you press and release the sustain pedal.

At the 12 o’clock position the noise level is natural. Above the 12 o’clock position the noise is louder and below the 12 o’clock position the noise is quieter.

EQ

The built-in equalizer is a powerful 3-band EQ with gain controls for the Low, Mid and High bands. The EQ characteristics have been fine tuned and optimized for piano sounds. The gain range is +/-18dB for each of the bands, which makes it easy to quickly achieve great sonic results.

The EQ can be switched on/off by clicking the LED button at the top.

Ambience

The Ambience section features four different reverb types and a Level control. The reverb types are:

•	Small Room

This simulates the acoustic reflections in a small room.

•	Large Room

This simulates the acoustic reflections in a large room.

•

Hall

This simulates the acoustic reflections in a medium size hall.

•

Theater

This simulates the acoustic reflections in a large hall/theater.

Output

Comp(ression)

This controls the amount of compression of your piano sound.

Width

This lets you set the stereo width of the piano sound.

Note that the Width control does not have any effect on the sound if you use only the “Vintage Mono” piano sound set(s), see “Selecting piano sound sets”.
