How good can a $54.95 plastic synth sound?
Check out the video demo above for an audio demo of an SX-150 Analog Synthesizer Kit that's been modified for MIDI control.
The SX-150 is a battery-powered toy synth kit, but it offers controls for LFO, pitch envelope, frequency cutoff, resonance, and attack/decay.
It doesn't have MIDI built-in, but it's a popular mod.
Pricing and Availability
The SX-150 is available for $54.95 via Maker Shed.
