OB-6 Key Specs Explained

6-Voice Polyphony

This synthesizer generates six simultaneous notes. You can play complex chords or layer sounds without notes cutting off. This polyphony count is standard for many analog instruments. It allows you to perform live without technical limitations on chord density. When shopping, compare this to digital pianos that often offer higher polyphony for large orchestral patches.

Analog Synthesizer

The sound generation uses analog circuits rather than digital samples. This creates a warm, organic tone characteristic of classic hardware. You get continuous control over sound parameters. This differs from digital pianos that rely on sampled recordings. Analog synthesis is preferred by musicians seeking traditional texture and real-time modulation.

Dave Smith Sequential

This indicates the brand and lineage behind the instrument. Dave Smith is known for influential synthesizer designs. Sequential is the current brand name for his products. This association suggests a focus on classic sound architecture. When comparing keyboards, this brand name signals a specific heritage in analog sound design and hardware engineering.

Polyphonic

This term describes the ability to play multiple notes at once. It confirms the instrument is not monophonic. You can hold down several keys simultaneously. This is essential for playing chords and harmonies. Most digital pianos are polyphonic, so this spec confirms the OB-6 fits standard musical performance requirements.

Design and Build Overview

The listing identifies this instrument as the Sequential OB-6 Keyboard, model OB6KEYBOARD. It is described as a polyphonic analog synthesizer. The data provided does not list specific materials, such as the type of wood or plastic used for the chassis. It also does not mention the physical dimensions or the total weight of the unit. You cannot determine from these specs if it is lightweight enough for frequent touring or if it requires a sturdy desk for stationary use.

The title confirms it is a keyboard format. This implies a built-in controller for playing notes directly. However, the exact key count, such as 61 or 76 keys, is not included in the provided data.
