The Korg Volca Bass is a completely analog synthesizer in a small package. For me it was the first step towards analog synthesizer and he is not only a good starting point is to experiment with analogue synthesizers, but it's just fun, sounding very good. As for the sound one finds many demo videos on Youtube or sounds on Soundcloud or on other sites. I confine myself here once on the essentials. The synthesizer has, despite its small dimensions of everything have "large" monophonic synthesizers, namely 3 oscillations, a filter, an envelope generator and an LFO to affect pitch, filter cutoff and envelope. Marks can about the "keyboard" (it's more of a touch screen) to be played, the octave is selected via a knob. In addition, a 16-step sequencer is to create basslines. This saves not only the notes, but can also record with parameter settings (Korg calls the motion sequence). In addition, on board is a Midi interface (MIDI IN), the Midi-channel can be set at the start. As output of the headphone output is used (mini-jack mono), additionally, you can synchronize multiple Volcas two sync sockets (In and Out), so they are also perfectly in time (you have to start the sequencer but even synchronously).
From the series of 3 Volcas (I have all 3) is the bass for me the one with whom I prefer to work. Even if he is bass, you can play with him in other tone ranges, so that leads and pads are quite possible. It is in contrast to Volca Keys however monophonic (you can not play chords, single notes only), but the 3 oscillators may be either used independently, but also be detuned so that quasi 3 different sounds are produced with a touch.
The build quality is good, although the housing completely of plastic, but the top of metal. Regulators are stuck, but sometimes a bit small. For this, he is very easy to transport and also the battery runtime is very good (certainly well over 10 hours with a set of 6 batteries). I have not yet bought a power supply, so I can also have evening times to experiment on the couch with some sounds and sound generation. Headphones pure Volca and have fun! Absolute buy recommendation for both the beginner as well as the interested sound tinkerers.
