The Roland E-20 features a primitive General MIDI soundset, which is not editable from the front panel, limiting its functionality for sound design.

The E-20 includes an internal power supply, meaning you only need a compatible cord that fits the plug, not an external power brick.

The E-20 is a 9-part multi-timbral device with 8 synth parts plus drums, similar to the Roland MT-32.

The E-20's engine is similar to the MT32, which is appreciated for its unique sound not replicable by modern plugins.

While sharing some engine similarities with the D50, the E-20 offers a limited number of sounds compared to more advanced models like the Roland E70.

At $75, some consider the E-20 overpriced given its limitations, suggesting a value closer to $50 is more appropriate.

As a MIDI controller, the E-20 offers only basic functionality with keys and pitchbend, lacking advanced control options.

The Roland E-20 requires a specific IEC C9 two-prong power cable, available online for around $15-$20, depending on the region and voltage specifications.

Confirm if the synth is intended for the US or European market to ensure voltage compatibility before purchasing a power cable.

Owners need to assign each part (upper, lower, bass) to a MIDI channel using the "MIDI" button for proper MIDI routing.

Missing volume faders and knob caps are noted issues, but they can be replaced easily if the parts are available.

Users appreciate its utility as a MIDI controller or for basic piano and essential sounds, especially when acquired for free.

Despite setup issues, the E-20 functions well as a MIDI controller, confirming its reception and transmission capabilities.

Ensure MIDI CLOCK RX is on to sync the E-20's tempo with your DAW's tempo, which is a common oversight.
