An effects unit, effects processor, or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing.
Bass pedals are an electronic musical instrument with a foot-operated pedal keyboard with a range of one or more octaves. The earliest bass pedals from the 1970s consisted of a pedalboard and analog synthesizer tone generation circuitry packaged together as a unit. The bass pedals are plugged into a bass amplifier or PA system so that their sound can be heard. Since the 1990s, bass pedals are usually MIDI controllers, which have to be connected to a MIDI-compatible computer, electronic synthesizer keyboard, or synth module to produce musical tones. Some 2010s-era bass pedals have both an onboard synth module and a MIDI output.

A bass chorus is an electronic effect used with the electric bass. It creates the same "shimmering" sound as a chorus effect for electric guitar chorus pedals, which recreates the sound of having multiple instruments doubling the same musical line. The difference is that bass chorus pedals are modified in various ways to suit the low pitch register of the electric bass. While several bass chorus pedal manufacturers have modified the chorus circuit so that it does not affect the lower register, others have designed the effect so that it can have an effect on even very low pitches.
The Yamaha DX21 is a digital controlled bi-timbral programmable digital FM synthesizer with a four operator synth voice generator which was released in 1985.

As a programmable synth, it enables users to create their own unique synthesized tones and sound effects by using the algorithms and oscillators. The instrument weighs 8 kg (17.6 lbs). On its release, it sold for $795.
The 12 Step foot controller is a bass pedal-style programmable MIDI controller pedal keyboard made by Keith McMillen Instruments which was released in 2011. It has small, soft, rubbery keys that are played with the feet. As a MIDI controller, it does not make or output any musical sounds by itself; rather, it sends MIDI messages about which notes are played to an external synth module or computer music program running on a laptop or other computer. Each key on the 12 Step senses the velocity, aftertouch pressure, and the amount of tilt the player is applying with his feet. The messages from the player's foot presses can be sent via USB to a computer-based virtual instrument or to a synthesizer or other electronic or digital musical instrument.
