It has 3 voice polyphony, a 16 step sequencer, and is battery powered and portable. At least that way you will have an idea of the time period over which an oscillator has an impact. MORE INFO: The Volca FM is like a mini DX7 (the iconic 1980s FM synth) but with a sequencer. I tried several visualisations but never really got to something that did the range of milliseconds to 300s justice! So I stuck with my somewhat linear display, but now calculate the length of each phase and display it. Add to this that the timing of an envelope phase is dependent upon the levels that it is going between and you have very flexible, but incredibly complicated. These envelopes have ludicrous ranges of up to 300s per phase! In fact they have a length of up to 317s when they are acting as a declining rate and 38s when acting as an increasing rate. This means an oscillator can continue forever after the sustain phase, which is particularly useful for ensuring modulators continue modulating during release.įinally, there is the length of the phases. Secondly, the start and end value of the envelope can be non-zero. The extra phase is right before sustain, meaning you can have a particularly interesting attack phase. First of all they have 5 phases, not the regular 4 of ADSR. can any of these apps also export DX7 patches that can be imported on the volca it is my understanding that the volca can import DX7 patches, can it like, it would be cool to have more overview and create patches on an external app instead of going back and forth and back and forth in the volca menu.
