Williams Allegro IV Digital Piano | Demo and Overview with Lynette Williams


collapse expand iconDescription

The Williams Allegro IV In-Home Pack kicks off with a showstopping Allegro IV digital piano loaded with 12 sounds—including a stunning concert grand, two vintage electric pianos, two organs, strings, acoustic and electric bass, vibraphone and choir. The Allegro IV has an 88-key, hammer-weighted and graded keyboard that provides the authentic feel of an actual acoustic grand, making it easy for players to transition from home practice to performing live on a real piano. An enhanced, upgraded speaker system with DSP control ensures you hear every nuance of the music you’re playing, and Bluetooth audio and MIDI connectivity lets you pair mobile devices to jam along with your favorite videos and dig into educational apps (such as the included trial period of Skoove Platinum piano lessons). The In-Home Pack also includes essential accessories so you have everything you need to play, practice and write songs at home. An attractive wooden stand holds your Allegro IV with sophistication and style, a padded and height-adjustable piano bench ensures comfort while you play or study, and a three-pedal controller provides grand piano-style execution of sustain, soft pedal and sostenuto passages. The Allegro IV In-Home Pack is available in black or white to match any décor or mood.

Allegro IV In-Home Pack 12 Sounds

12 Onboard Sounds

The Allegro IV digital piano includes 12 scrupulously crafted voices that cover almost every style of music for your performance, recording and songwriting needs. There’s a gorgeous Italian concert grand, two organs (rock and perc), two vintage electric pianos (tine and reed), two basses (electric and acoustic), vibraphone, string pad, synth pad, choir and a bright acoustic piano. Adventurous players can exercise their inner sound designer by splitting or layering sounds on the keyboard for massive sonic textures, as well as processing basic patches with built-in effects, such as 2-band EQ, reverb, chorus and rotary speaker. In addition, the Allegro IV enriches its incredible sounds with a completely redesigned and upgraded audio system. Speakers are mounted inside resonant cavities within the Allegro IV’s frame that are ported—just like professional studio monitors—to deliver a truly immersive experience with rich lows, articulate mids and shimmering highs.

Allegro IV In-Home Pack Bluetooth Audio and MIDI

Bluetooth Audio, MIDI and USB

The Allegro IV effortlessly links to computers, DAWs and tablets via Bluetooth, USB, MIDI, an AUX input and mono/stereo audio outputs. Pair your phone using Bluetooth and play along with songs, YouTube lessons and other educational media through the Allegro IV’s speakers. Make tracks by using your favorite recording software over USB with the Allegro IV’s built-in audio/MIDI interface. Jam with friends and/or dive into group songwriting sessions by plugging into a keyboard amp or PA system. You can even use the free Williams app over Bluetooth to customize sounds and control the piano. The Allegro IV isn’t just for practicing piano at home.

Allegro IV In-Home Pack Bluetooth Stand and Pedals

Wooden Stand and Pedals

Your Allegro IV should look as smart as your repertoire, so the wooden stand really sets the scene. Bringing a touch of class to any living room, bedroom, dining room or practice alcove, the stand firmly attaches to the Allegro IV, so if you want to punish the keys like the legendary Jerry Lee Lewis, zip up and down the ivories like Lang Lang or perform whisper-to-roar dynamics like Alicia Keys, you can rest easy that the keyboard will remain strong and secure. Similarly, the three-pedal controller—which adds sustain, sostenuto and soft pedal to your performance technique—fastens to the Allegro IV via steel bars, which look great and feel solid.

Allegro IV In-Home Pack Piano Bench

Padded, Adjustable Piano Bench

No more grabbing a desk chair or rickety stool when you want to play or practice. The Allegro IV’s padded leatherette bench is comfortable, improves performance posture and can be adjusted to accommodate the heights of children and adults, as well as tall and no-so-tall pianists. The wide bench and steel legs ensure that the only things moving are your fingers flying across the keyboard.
