As it both connects and is powered directly from USB, the USB Solo is all you need to control an analogue synthesizer from a computer. With no MIDI interface necessary, and no external power supply, cabling clutter is kept to a minimum. The USB Solo still maintains the famous Kenton tuning stability though, as well as full scale range on the CV and auxiliary outputs thanks to its internal power circuitry.

The CV output can operate at 1V/Oct, Hz/Volt or 1.2V/Oct. The scaling and tuning are adjustable, to accommodate any unruly synths. The Gate output can work at several different voltage levels, and can also be set to work a S-trig instead. In addition to this, the USB Solo also features a Sync24 output, so your vintage Roland equipment can join in as well.

The USB Solo is a class-compliant USB MIDI device, and doesn’t require installing any drivers, just plug and play.
