The Yamaha ELS-01C is often compared to a Motif on steroids, offering extensive MIDI control capabilities across tiers and foot pedals.

Advanced 8-operator FM synthesis is noted in models related to the ELS-01C, providing a sophisticated sound engine for complex tones.

The ELS-01C's expression pedal may include programmable toe switches for dynamic sound balancing or switching between sound banks on the fly.

Registration memory presets can be stepped through using the right footswitch on the expression pedal, allowing seamless sound changes during performances.

Preset buttons located between the two main keyboards allow quick sound changes, crucial for live performance adaptability.

Although initially priced at $10,000, these models can depreciate heavily, sometimes being found for as low as a few hundred dollars.

Unlike the CS-80, the Electone E-70 and ELS-01C use digital oscillators, which improve stability but may not capture the analog warmth.

Yamaha Electone models like the E-70 share lineage with the CS-80, famous for its use on "Who Are You" by The Who, though they differ in oscillator type.

As a learning tool, the ELS-01C can function as a unique MIDI controller for organ practice, offering multi-channel MIDI setups.

The Electone ELS-01C can stack multiple instrument sounds like woodwinds, strings, and brass, controlled by key velocity, enhancing dynamic performance capabilities.

The drum parts can be pre-sequenced and triggered separately, potentially mapped to keys or using external triggers, enhancing flexibility for complex arrangements.

Owners note the ELS-01C's size and weight make it comparable to a "400 lb desk," complicating setup and serviceability.
