What additional equipment do I need to use GS Music synthesizers?

Appart from the synthesizer you may need:

  • A MIDI cable (DIN-5)
  • A MIDI controller or keyboard
  • A USB cable to connect the unit to a computer (USB MIDI)
  • A TS or TRS ¼'' audio cable and an amplifier or a pair of headphones.

¿Can I use the synthesizers with a guitar?

There are two ways to use our synthesizers with a guitar.

The first one is by using a guitar to MIDI converter or a MIDI guitar. By doing this, the synthesizer would be controlled by the guitar, making use of all its stages, including the oscillators, filter, amplifier and effects.

The second one is connecting the guitar to the external audio input (available in Apollo and e7). By doing this, the guitar signal would be mixed with the oscillators and then passed through the filter, amplifier and effects. Have in mind that it will be necessary to activate the amplifier somehow, for example sending some MIDI note or using the gain CV input. If the guitar signal is too weak, a pre-amplifier may be used.


All our synthesizers have a 1 year warranty from the time of purchase. In case of any issue, don't hesitate to contact us.
