One up-front thing about sound design on it: while it is possible to make patches directly on the box, it’s something that really ought to be done on the software editor (the polyphonic version coming out later this year is going to have a much bigger screen). However, the patch structure itself is pretty straightforward, it’s got a lot of options but conceptually it’s much like any other synth. The only part that gets a little engineering-ish is the modulation options that require other modulators feeding into it, e.g. to make a wavefolded LFO you need to have a wavefolder modulator using an LFO as its source, but the wavefolder by itself doesn’t produce anything. Both the box and the software editor will let you see the current oscilloscope output of any modulator so you can see what it is, or is not, doing.
