The octave buttons are used to shift the keyboard up or down in one octave increments. This extends the range of the keyboard in either direction, which lets you play notes that lie outside the number of keys available.

The more buttons the device has, the more complex the input can be.

The pitch wheel alters the pitch and timbre of a sound in real-time. It can give fine tuning control from fractions of a semi-tone to huge multi-octave pitch swings.

The button is used to select independent banks of continuous controllers. Effectively, this allows you to control more independent parameters with the knobs, faders and buttons. The bank selector button is used to switch among the available banks.

The mod wheel is used to add expression, or to modulate (change) various elements of a sound or sample.

Similar to a weighted action keys, but with less resistance and a slightly springier release, semi-weighted keys are popular with many players. If you don’t need realistic piano response, but also don’t care for spring-loaded synth actions, a semi-weighted keyboard might be ideal for you.

Velocity sensitive keys are just spring loaded keys that sound out louder the harder you hit them. If you "lightly" press a key, the sound will be quiet; the harder you press, the louder it gets.

The pads section is ideal to trigger loops and samples, using your finger drum skills.

More memory locations allow users to save their preset/setup and have them ready to use again and again.
