SX-150_and_Theremin

The gakken theremin can be used to control the SX-150 which has a much better tone and a LFO for that Violin / cello effect. The ext input of the SX-150 is a Frequency to voltage converter and so any synth can be used to control the pitch of the SX-150 but a signal with a high amplitude is needed (about 3v+)
