Recently released Korg volca fm is a portable version of the legendary Yamaha DX7 which made a lot of noise on the market back when it was launched. The successor tried its best to adopt the maximum of possibilities incorporating all the features in a more compact design. It can be easily integrated with other electronic instruments.

Its sound engine is all about the frequency modulation synthesis. It should be noted that volca fm is capable not only of its spiritual predecessor sound space revival, but introduces an individual set of new, more powerful functions.

Obvious improvements concern the easier programming than that featured in DX7. The new interface makes it much simpler to create your own sounds from scratch. FM synthesizer allows storing up to 32 presets. Like DX7, the synthesizer includes 6 operators with a range of 32 algorithms which skillfully synthesize ringing metallic tones, punchy basses and eccentric effects.

The step sequencer is combined with curious parameters. It offers up to 16 tracks managed by Active Step, Pattern Chain or arpeggiator (3 Rise, 3 Fall, 3 Random). In the left part of the front panel there are main sliders and knobs: transposition, velocity, modulator and carrier. A low-frequency oscillator (LFO) is also located here. There are ports to the right at the top: MIDI IN, Sync Out, audio output for headphones (3.5 Mini Jack). It is worth noting that all interface parameters, from transposition and velocity to modulator and carrier can be automated.

It is impossible not to mention the unique ability of adding original DX7 patches. Moreover, countless presets can be found on the Internet. To everyone's surprise, the polyphony of a tiny monster features only 3 voices, but among the modes there are: Poly, Mono and Unison. As a nice bonus - built-in chorus which adds a lush sound in the style of the 80's.
