Great little synth for its price
Crane 11.06.2021
The volca keys is a nice little box of character. It has plenty of different flavours to choose from and can sound very lo-fi if you play around with its onboard delay and aggressive filter.

I like the fact that the volca keys is a one-knob-per-function synth without any hidden menus or settings. That way you can get really hands-on with it and makes it a great synth to learn synthesis as well.

The only quirk of this volca is that its sequencer starts skipping steps once you plug in a mono TS cable. When using regular stereo TRS cables, I get a really soft and noisy signal from the Headphone OUT. When using a mono TS, it's really loud and clean. But due some technical flaw in the keys, the sequencer might skip steps because of it.

Generally it's a great little box for the money and certainly works well when jamming with other volcas!


(Too) many features in a small box

Many features packed into a small synth. I'm sure this works for some people, but I found it to be way too limited. Although, I know, it's very cheap.

Here are some limitations that I found annoying. Some of these might be hard to guess before actually using the unit:

- It's not polyphonic, it's paraphonic. There are 3 VCO's but they share the same VCA. In practice it sounds like the held notes would be triggered again when you play a new note.
- Although the Keys receive velocity when played live, the sequencer does not record it. So the velocity of every note is 100%.
- No ability to bypass recording midi (key) notes from an external midi-keyboard.
This means that if you simultaneously play live on a keyboard and record your automations on the Volca itself, the notes you played get recorded on every loop, over and over again. You have to record the automation separately.
- Sequencer has only 16 steps. Although the scale can be adjusted: 1/1, 1/2 and 1/4.
- Peak (resonance) cannot be automated or affected through midi.
- No MIDI out. Although you can relatively easily make your own. Similarly to Arturia BeatStep, I would suggest a 1/8 TRS jack (next to the MIDI IN jack).
- Only headphones out. If you plan not to use headphones, you need (half of) an insert cable or some other special configurations.
- The scope of the sounds that you can produce with this is very limited. Although the automation helps a lot, but still.

First of all you can't find other real analog synths in the market with up to 3 part polyphony at this very low price.
Sounds like a real analogue synth all the VCO, VCF, LFO knobs help you create beautiful vintage sounds
the delay is a bit noisy it's dirty and imperfect but it could be useful in certain situations.
the mini keys are ok for functions but very bad as keyboard especially for chords.
The sequencer and recording is not for me and I prefer using my DAW sending midi to volca
for the price is a good instrument


Great with Midi
PADPA 28.10.2021
If you can line in with a Midi keyboard that produces analogue sounds, this is an awesome piece of kit. The in built sounds aren’t the best.
